Something a model could not do, and so wrote a note about instead
Asked to remind somebody every Monday, a model looked down its tool list, found notes_create described as "something worth having in a later conversation" and memory_add beginning with the word Remember, wrote a note, and reported that it had scheduled something. Every screen agreed with it. There was no scheduling tool at all -- the near-misses were the only thing there was to reach for, and nothing anywhere said the thing it was being asked for existed. The seam had been left open on purpose: Schedule.origin has defined ORIGIN_MODEL, with no writer, since scheduling shipped, and services/schedules.py says in its first line that it holds what the routes *and the tools* both need. This is the tool that was meant to go through it. Four of them, and a thin layer: rule.validate is still the one total normaliser the form and the compile share, schedules.create still writes the row and the task chat together, and rule.describe still says what came out. A second dialect for models would mean two definitions of "every other Tuesday" and one of them going quietly wrong. The result is that description, never "done". A schedule is invisible until it fires, which may be days away, so the sentence in the reply is the only moment anybody can check that Monday was read as Monday -- and the tool says so, in the text the model reads back. The list badges the ones nobody typed. Gated on schedule.use rather than a permission of its own: somebody who may set one up by hand may say so to a model instead, and a second checkbox beside the first would only ever be answered "the same as that one".

A connection that cannot point at the machine it is running on
"Nothing runs on the LLeMbas host" is the sentence the absent sandbox and the absent local MCP rest on, and an SSH profile aimed at 127.0.0.1 walked straight past it -- through a real login, with every gate in policy.py still applying, onto the machine holding the database and the Fernet key. From the SSH layer down it is indistinguishable from a container on the network, so nothing here could have noticed. One switch, three positions: never, one named port, anywhere. The middle one is the one with a real use -- a container that published its SSH port on the loopback interface is genuinely somewhere else -- and port 22 is refused even there, because that one is this host's own sshd. Enforced in five places, because a row can predate a setting: saving a profile, `session.resolve` (the control every agent tool, the terminal and the canvas go through), the composer's picker, browsing, and the draft the panels open against before a chat exists. Check refuses before it opens its socket rather than after. And the recognition never resolves a name on the request path. `refusal` runs several times per page render; the first version of this looked names up inline and the suite went from two minutes to not finishing. Literal forms are decided from the string, a name is settled where a network call is already expected, and the answer lives on the row. The gap that leaves is written down rather than discovered.

An edge that is not drawn, and a panel that stopped eating the site
`hx-get=""` is not "fetch nothing". htmx looks for the attribute, not for a value, so the empty one the canvas rendered before a chat existed was a real request for the empty path -- which the browser resolves against the current document. Opening the canvas on the new-chat screen fetched the new-chat screen and swapped the whole site into the panel. The attribute is omitted now, and a test refuses an empty verb anywhere on the page. Which panels can exist is the server's answer; which are offered is the browser's. Both need an agent chat on a chosen connection, and before a chat exists those are controls in the composer -- so answering with the first profile offered a terminal on an ordinary chat with nothing selected. They follow `lembas:agent-target` now, and an open panel whose target goes away is closed rather than left showing one machine under another's name. `.tabs__body` is only sometimes the scroller: true where the tabs are a bounded flex child, false under the admin layout, where the page scrolls instead. So setting its scrollTop on every tab change had never once run on /admin/prompts, silently, while the reader was dragged to the bottom of a document that had just got shorter. The rule names the position now, and the handler finds the container that actually scrolls. The two top borders come off. They were what made the misalignment at the bottom of the shell visible; `--footer-height` stays, because two ends at different heights are visible without a line to prove it. The top of the shell keeps its line -- there, everything is `--header-height` and aligns by construction. And one version. pyproject carried its own copy and had drifted three minors from the one everything actually reads. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Narrow a chat before it starts, and find a file rather than spell it
Six things, all found by using the thing rather than by reading it. The scope menu only appeared once a chat existed, on the reasoning that there was no row to post to. True, and the wrong conclusion: the harness puts a tool's guidance in front of the model the moment the tool is offered, so the menu could not be reached until after the model had been told how to keep notes and handed the tools to do it -- and switching it off then does not un-send that turn. It is on the new-chat screen now and writes nothing: `_scope_context` builds a stand-in Chat, which is `draft.as_chat`'s trick again, and the switches ride along with the first message. Checked means on and a browser submits only the ticked boxes, so every gate also renders a hidden input naming it and `start_chat` subtracts one list from the other; inverting the control would read backwards under a menu that says everything is on unless you say otherwise. Only the off ones are written, because absent means on and one representation of it is what keeps "why is this off?" to a single answer. Nothing is validated against the offered set, since scope_json narrows after every gate -- naming a gate that was never offered switches off something that was not on. Then the scheduling instructions, audited against a 4B model on this machine rather than against my own reading of them. Ten realistic requests, ten compiled, twice over -- so the prompt is sound. What was not sound was `describe`, which built a phrase by joining fragments and read "Every the 1st at 09:00" for the commonest monthly schedule there is, and "Every of January" for a month with no day. That string is the whole of what somebody sees before approving a schedule and the whole of what the model is told about its own chat, so a phrase nobody can parse is a review step nobody performs. It reads as English now, collapses Monday-to-Friday to "every weekday" and seven days to "every day", and every case in the test is a rule that model actually produced. The one mistake it made was naming Wednesday for "every other tuesday", so the weekday numbering is spelled out rather than left as "0-6, Monday is 0": getting that wrong is the error here that still looks like a working schedule. Roughly one call in six also came back empty -- a local runner swapping models under the request will do that -- so an unusable reply is asked for once more before giving up. Not on an LLMError: an endpoint that refused will refuse again, and the reader is better served by the form than by waiting twice for the same answer. Canvas asked for a typed path, which was the last control in the application expecting somebody to remember an absolute path on another machine -- the same complaint the folder page's directory field answered with a picker. /browse takes pick=file and the same fragment makes files buttons, because a second copy of that listing is a second place for the path arithmetic to be got subtly differently. The button carries data-canvas-open rather than an hx-post since the path is not known until the dialog closes, and ui.js posts it through htmx.ajax so the response lands in the panel exactly as every other canvas action's does. The key is `agent:<path>`, so a file opened by hand and one opened by the model are one tab rather than two spellings of it. The tabs already existed and already closed; they now square off at the bottom and the active one takes the body's background, so which is selected is structural rather than a tint nobody can see in a theme they did not choose. Highlighting was already there for every language named and is checked for fifteen of them. Three smaller ones. Tabs kept their scroll position, so switching from a long panel to a short one left the browser clamping to that panel's bottom: the end of it above a screen of nothing, which reads as a page that failed to load. Nothing in CSS can reset a scroll position. The sidebar's footer and the composer sit either side of one vertical edge and were both content-sized, so their top borders met it at different heights and read as one line that had been broken -- `--footer-height` is a calc of the pieces the footer is built from, applied as a min-height to both, which is exactly what `--header-height` already does at the top of the shell. And "Add a workflow" sat flush against the list it adds to, stated as an adjacency because `.btn-row` is right to carry no margin everywhere else it appears. Both pieces of JavaScript were driven under a DOM stub before committing, which is how the tab listener's delegation and the canvas button's six behaviours were checked at all -- `node --check` parses a file that does nothing.

Bump the version, because the service worker is keyed on it
app.js gained the backward scroll anchor and two stylesheets gained rules the new pages need. The worker caches static assets under a name derived from /sw.js?v=<app version>, so without this a returning browser keeps serving the old ones -- and the failure is the quiet kind: the schedule form renders with every fieldset showing at once, and scrolling up through Messages drags the reader off the page, on precisely the browsers that have been here before. 0.8.0 rather than a patch: three sections, two tables and a permission that did not exist.

Say what actually failed, and tell the model how to use the thing
Two problems, both found by looking rather than by guessing. ComfyUI writes its history entry in task_done and nowhere else, so the entry appearing IS "finished" -- but it sets completed=e.success, which means an out-of-memory, a cancelled job and a broken node all stay completed:false for ever. await_images waited on that flag. So every failure sat for the full 600s timeout and then reported a timeout, when ComfyUI had known within one second and written down the node, the exception type and the message. Proved by causing both against the real instance: an OOM now raises in 1.0s and an interrupt in 4.0s, each naming the node. The terminal condition is a record with a status, and status.messages is read for the last execution_error or execution_interrupted. OutOfMemory and Interrupted are their own classes because they are the two failures with an obvious next move: the first tells the model to retry at a named smaller size -- worked out from what it actually asked for, since "use a lower resolution" against a request that was already 512x512 is advice nobody can follow -- or with a lighter checkpoint; the second says somebody pressed stop, so do not simply start again. Everything else gets the reason and no advice, because a model told to try again after a broken workflow tries the identical thing. The OOM message is cut to its first sentence. The rest is allocator advice -- PYTORCH_CUDA_ALLOC_CONF, fragmentation notes -- addressed to whoever runs the box and meaningless to a model, in a tool result that is already a failure. Second: the parameters were described in the register of a reference table, and "cfg: prompt adherence, default 8" tells a model nothing it can act on. Measured on a 4B model, same request, same everything else: with the old wording it sent prompt and template and nothing more -- so 512x512 on an SDXL checkpoint, which is exactly the duplicated-limbs failure the width description now warns about. With descriptions that say what each value does to the picture and when to move it, the same model sent a portrait 1024x1536 and a deliberate sampler. ~3KB of schema per request in a chat that can draw, and the difference between having ten parameters and having one. docs/image-generation-instructions.md is the long version for the admin instructions box, for models that need more than the harness can afford to carry on every request in every chat.

A seed of -1 means random, as it does everywhere else
Omitting the seed was already random. Passing -1 was not: it went through the uint64 wrap and arrived as 18446744073709551615, which is a perfectly valid *fixed* seed -- so "give me something new" returned the identical picture every time, silently, and the retry loop would have redrawn the same rejected image until it ran out of attempts. -1 is what ComfyUI's own interface uses for random, and A1111, and everything else that has ever asked somebody for a seed. A model that has read any of them will write it, so the one reading that had to work was the one that did not. Any negative value, not only -1, because the sentinel is the *idea* rather than the number and a model that writes -2 means the same thing. Zero stays a real seed: it is the boundary this change could easily have swallowed, and it is one somebody deliberately picks. Confirmed against the real ComfyUI: -1 now sends a random uint64 that it accepts and draws from. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Draw a picture, on a ComfyUI you are running
The last unbuilt capability, and built the way CLAUDE.md said it had to be: a
ToolDef reaching resolve_tools plus a permission and a capability flag, not a new
code path. The only genuinely new UI is one branch in the transcript.
services/images/ is three modules. comfy.py speaks HTTP -- submit, poll /history,
fetch the PNG, /free, and an /object_info discovery for the admin page only.
Polled and not socketed, because holding a connection open for the length of a
generation is the live-connection state the whole ssh.py design forbids, and the
thing being waited for takes tens of seconds anyway. The base URL is exempt from
the SSRF guard by construction, exactly as Connection.base_url and the audio
endpoints are -- said out loud in the docstring, because a default of
127.0.0.1:8188 is precisely the shape that guard exists to refuse and therefore
reads as a hole rather than a decision.
workflow.py fills a template, and the one thing that matters is that it walks the
parsed JSON rather than the text of it. A value that is exactly "{{steps}}"
becomes the number 20; ComfyUI validates types and refuses the string. A
placeholder inside a longer string is still text, which is what makes
"{{prompt}}, masterpiece" work -- and text substitution would additionally mean a
prompt containing a quotation mark produced a document that no longer parses, on
the one input guaranteed to hold arbitrary text. Which node holds the prompt is
the administrator's statement rather than a guess from node types: sniffing for
the first CLIPTextEncode works on the shipped workflow and on nothing else, and
swaps positive for negative the first time somebody reorders them. seed has no
fixed default, because one would make every unspecified generation identical and
make the retry loop redraw the same rejected picture four times.
tool.py is one call, one finished image. Returning every attempt to the
conversation would cost a round each, make the ceiling advisory rather than
enforced, and walk the reader past every reject -- so the reviewer lives inside
the tool and is asked about *bytes*: an attempt about to be discarded should not
leave an Attachment behind, so it sees a downscaled preview built in memory and
only the kept image is written. Anything that goes wrong in review is a keep;
losing a picture because a judging request timed out would be the check
destroying the thing it was checking. The last attempt is kept whatever the
verdict, so a request always produces something. Rejects are recorded, not
stored.
Preserve VRAM unloads the chat's own connection and nothing else, because the
memory being freed belongs to one machine: local llama-swap answers GET /unload,
and a box on the network has no reason to be unloaded when ComfyUI wants memory
here. The swap goes round the review rather than round the tool, which costs two
model loads per retry -- so the two settings are independent and the page warns
when both are on. Nothing loads the LLM back: the reply's next request does, and
that step exists in the description and not in the code, so the code says so.
Two rules elsewhere had to be drawn for the first time. message_payload sends
images only on user turns -- no assistant message had ever carried one, and the
moment one does the multimodal list form on an assistant turn is rejected by
OpenAI and most local runners, breaking every later turn in the chat. And
files.store gained keep_original, because _process_image turns anything without
alpha into JPEG q85 at 1400px: right for a phone photo, a visible loss on the one
output this feature exists to produce.
/image sends the ordinary message with force_tool, which becomes tool_choice for
the first round only -- left in place the reply would draw a picture, be asked
again, and draw another. FORCEABLE_TOOLS is an allow list because the name is
read off a form.
ToolContext gained chat_id, and that fixed a tool nobody had ever successfully
run: _run_scratch_write read context.chat_id on a dataclass with no such field,
so every call raised AttributeError, swallowed by run_tool's blanket except into
"the scratch_write tool failed" -- indistinguishable from a model calling it
wrongly. The test that existed asserted the family and the risk, which are
properties of the declaration rather than of the code.
Verified against the real ComfyUI 0.27.0 on this machine rather than against
documentation: every endpoint shape here was read off it, a generation ran end to
end through the client, the reviewer was shown a matching and a mismatched prompt
and answered KEEP and RETRY correctly, and the unload hook fired for the local
llama-swap and not for the remote box.

Refusing can say why, and the why is an instruction
"Don't" told the model it was refused and nothing else, so it did the one sensible thing left and asked what you would rather -- a whole round spent on something you knew when you pressed the button. "Give reason" opens a box beside it, and what you write goes back with the refusal. The reason changes what the model is *told*, not only what it reads, and that is the whole of the feature. `_not_allowed` branches: given nothing to go on, "say what you were going to do and ask what they would prefer" is right; given a reason it is exactly wrong, because the answer is already on the screen above and the model spends a round asking for it again. So it is pointed at the reason and told to carry on from it. The "do not look for a way round" half is kept either way -- that half is about the refusal and holds regardless. A card-level field rather than `text.<key>`. One card covers everything in the round for the reason the primitive exists, so one reason answers the round; and on an approval card `text.<key>` already means a corrected command, which is a different thing arriving in the same shape. Read only on a refusal, so a reason typed and then abandoned by pressing Allow cannot travel with a permission. Bounded where the Reply is built, so nothing downstream thinks about length, and put on the tool event as well as in the result -- a transcript saying a step was refused without saying why is one you had to have been watching to understand. It is also the one thing in a tool result that is genuinely not untrusted: the reader's own words, stated as theirs, needing no fence. Both halves of the control are in the DOM with one hidden and the textarea disabled while hidden, which is the rule the edit box beside it already states: a field created by a click submits nothing when the click handler fails, and an empty `reason` arriving would have to be told from one somebody cleared. The version bump is not incidental. chat.css changed and the service worker caches it under a name keyed on the version, so without it the first reload serves the old stylesheet.

Bump the version, because the service worker is keyed on it
The worker caches static assets stale-while-revalidate and names its cache after the version in `/sw.js?v=`, deleting every cache that is not the current one. So without a bump the first reload after a release serves the previous app.js and chat.css and only the second gets the new ones -- which for this release is a transcript that does not refresh itself and a jobs panel that still runs into its own border, i.e. exactly the symptoms it fixes, on the reload somebody makes to check.

An sse-swap element must never contain another
An agent reply rendered nothing from its first tool call onwards. An ordinary
chat was fine, and that difference is the whole diagnosis: `#steps-{id}` is
itself an `sse-swap` target, so its innerHTML is replaced every time a round
closes -- and I had put the live `reasoning` and `render` containers *inside*
it. Every round boundary tore out the two elements the next frames were aimed
at, in the same pass that aimed them. An ordinary chat closes no steps, so the
swap never happened and nothing was ever torn out.
The tail moves back out to `_message.html`, as siblings of the steps container.
That removes the trick where the `steps` frame re-emitted the tail empty in
order to clear it, and replaces it with something simpler: `reasoning` and
`render` are now sent on every pass including empty, which is what clears them
when a round closes. Safe here and not before -- they carry the open tail only,
so an empty one means the tail is empty, where the version that carried the
whole reply would have wiped the answer. `steps` is the frame that must never
blank now.
`tests/test_chat.py` walks every template and refuses any `sse-swap` element
inside another; checked against the bug before being kept.
Two things I had left undone and should not have. `.msg__steps` had no styling
at all, so the sequence ran together with nothing separating a paragraph from
the command it led to. And `.msg__body--live:not(:empty) + .msg__waiting .dots`
stopped matching when those two stopped being siblings, so the dots pulsed
beside a finished answer for ever; it is a `:has()` on the bubble now.
The version bump is not cosmetic either: the service worker keys its cache on
it, so without one every browser kept serving the previous release's CSS and JS
against the new markup.

Two selects that never wrote anything, and a queue
The approval card in Auto mode and the missing /effort were one bug. Both
selects hung their hx-patch on an empty sibling form reached by form="…",
and htmx binds a trigger to the annotated element: change fires on the
select and bubbles to its ancestors, which a sibling is not. The live rows
read agent_mode=manual and params_json={} while the browser showed Auto and
Effort: high. policy.py was never involved.
The verb moves onto the control; the empty form stays as value scoping,
which is the half of the CLAUDE.md note that was right. conftest gains
control_named so a test asserts the element carrying the name carries the
verb, rather than asserting the markup that was there throughout.
The composer's highlight was a third instance of the same carelessness in
CSS: .tok-mention is written for the transcript and scoped to nothing, so
the mirror painted its token in accent-coloured monospace over the
textarea's own text. Scoped under .msg; the mirror restates transparency
and font rather than inheriting them, and bleeds by box-shadow.
/effort is now offered before the first prompt and _new_chat reads it.
/index re-walks the project directory on demand, file_write drops the
listing it just invalidated, and the index ladder falls through to SFTP on
a host that refuses exec instead of returning nothing.
A second message during a reply is queued rather than starting a second
concurrent generation: a real Message row with queued set, so it survives a
restart and can be withdrawn. _drain hands one on at the end of a reply,
_inject takes one in at a tool-round boundary so an agent can be steered
mid-task. Stop leaves the queue undelivered. The terminal's Auto toggle
becomes off/copy/send, and send posts straight to the chat without touching
the composer.
@ now offers notes, skills, this chat's attachments and a URL to fetch; a
knowledge base attaches as a reference rather than a copy. copy_document
carries provenance, which was the one attach path that dropped it.
Also fixes an unrelated live bug: the round loop compared against the
global MAX_ROUNDS of 3 while sizing itself from the agent budget of 40, so
agent replies stopped after three rounds and reported forty.

The menu that never appeared, and the reason it never did
composer.js built its menu lazily inside show(), and refresh() wrote list.innerHTML before calling it. `list` is null until build() has run, so the first `/` or `@` ever typed threw a TypeError and took the handler with it. The menu has never appeared in any browser. That is why /compact "isn't there": nothing was. I shipped it having only run `node --check`, which parses the file happily. So this also brings the thing that catches it: a DOM stub driven under node -- not committed, hard rule 1 stands, it is an instrument like curl. It reproduced the crash in one run and immediately found two more: choosing a command from the menu left `/help` sitting in the box so the next Enter ran it again, and Tab completed nothing. Tab now completes and Enter runs, which is the split that matters for a command taking an argument. `.select--sm` was used three times and defined nowhere. I deleted the copy in chat.css and left a comment saying it "is defined once, in app.css", where it did not exist -- so those selects fell back to plain `.select`: width 100% in a flex row where four siblings wanted the same, all of them shrinking together until each was a few characters wide, and half a rem taller than everything beside them. That was the whole of "the connection switch needs to be wider". The connection and directory move to the topbar. They cannot change -- update_chat refuses both with a 409 -- so they are facts about the chat, of a kind with the Temporary badge, not controls on the message. The mode stays by the box. Compaction says it is working. It makes a model call that takes seconds and had no indicator anywhere: `hx-indicator` appears nowhere in this codebase, and the Generation.status channel that says "Summarising earlier messages…" for the automatic path cannot be borrowed, because it lives in the streaming bubble and this endpoint refuses to run while any message is unfinished. The overflow menu now runs the same code as /compact rather than posting for itself, so there is one implementation, one spinner, and one place the endpoint's four carefully written 409s finally reach somebody. /effort, low medium high, per chat with a per-model default. It goes out twice because there is no field that works everywhere: OpenAI and vLLM read reasoning_effort, llama.cpp's own docs say other values "have no effect" and its maintainer says the field "simply gets dropped without error or logging" -- what reaches gpt-oss behind it is chat_template_kwargs. Both are sent, and only once an effort has been chosen, so a provider strict about unknown parameters sees exactly the request it always did until somebody opts in. The control appears only on a model marked `reasoning`, a flag that has existed since the beginning with no reader at all. Mentions and recognised commands are marked as you type -- a mirror behind the textarea holding the same text with every character transparent, contributing nothing but a rounded rectangle, so a pixel of drift is a misplaced rectangle rather than a doubled glyph. A command is marked only when it resolves, so `/thoughts on this` visibly is not one before you send it. And again in the transcript, where user turns had no render step at all and now escape before they inject. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Bump the version the application actually reports
pyproject and lembas.__version__ are two separate strings and only the first
was moved. The one that matters at runtime is the second: base.html registers
the service worker as sw.js?v={{ version }}, so a release that does not change
it leaves every installed browser serving the previous release's JavaScript and
CSS out of cache. A visible redesign shipped behind a stale worker is a
redesign nobody sees.

A terminal panel beside an agent chat
A real shell on the chat's own connection, opened and closed like the inspector and never beside it. The modes govern the model; what a person types is theirs, since they hold the credential and could open the same shell with an ssh client. The model cannot see the panel -- a button copies the output you choose into the composer. The session outlives the socket: closing the panel leaves a build running, and coming back reattaches with the scrollback. Two tabs share one shell and the smaller window decides the size. It ends on an idle timeout, on deleting the chat, on disabling, moving or deleting the connection, and on a restart -- which says why rather than quietly opening a fresh shell that has lost the working directory. The nginx template's `Connection ""` is right for SSE and fails every WebSocket handshake, so `location /` now uses a `map $http_upgrade`; update.sh grows a drift check for it, because the only symptom on a stale vhost is a panel that cannot connect.

Custom HTTP tools an administrator defines
A row in custom_tools becomes a ToolDef like any built-in, offered beside the thirteen. The registry had to stop being an import-time constant for that: `resolve_tools` now returns the schemas *and* the runners together, carried to the loop on the ToolContext. That closes a hole on the way. `run_tool` looked names up in the global REGISTRY with no reference to what had been offered, so a model naming a tool its chat was gated out of -- a family switched off, a permission the reader lacks -- had it run anyway. The resolved set is now authoritative. Arguments come from a model, so an argument may fill a hole but never move the target: the scheme and host of a URL template are literal, values are escaped for where they land, and the origin is pinned afterwards. Every redirect hop is checked the way services/fetch.py checks one, and the secret is dropped if a hop leaves the origin it was issued for. Also fixes the tool-activity block claiming every library tool had "searched the web", which it has done since the second family landed.

A suggestion card sends its prompt
Filling the composer and waiting for Enter made the card a form to review rather than a thing to press. One click, one reply. That changes what a prompt has to be. The built-ins ended mid-sentence -- "My plan: " -- because nothing was sent until the person finished the thought; sent cold they are a model guessing at material nobody gave it. All three are rewritten to ask for what they need, so the first reply is the right question instead. There is a test that they end as complete sentences, since the failure is silent and only visible in the answer. requestSubmit, not submit: it fires the submit event, which is what htmx listens for. Same call the Enter key already makes. Version bumped because app.js is what changed, and the service worker caches it -- without the bump the first load after this would still only fill the box.

Version 0.3.0
A regenerate button that works, per-reply metrics, temporary chats, prompt suggestions, an admin request inspector and compaction. The bump also invalidates the service worker's cache, which is keyed on it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Every injected prompt becomes editable, and several get written
The instructions LLeMbas puts in front of a model were hard-coded: six
strings in a GUIDANCE dict, two headings, and the title request inline in
chat.py. An operator could not see what was being sent, let alone change
it, and there was nowhere for a custom tool to contribute its own guidance
when custom tools land.
services/prompts.py now holds each piece as a Fragment, and /admin/prompts
edits them with a preview of the whole assembled system message including
unsaved edits. harness.py keeps only the decisions -- which fragments apply
to this request, and what their variables resolve to.
The design turns on one choice: a fragment carries its gate as data
(families, requires, when_tools) rather than as a callable, because a
database row can carry the same three fields. Custom tools will therefore
register a fragment source and change nothing else -- there is a test that
says exactly that, and it is the reason the rest of the shape is what it is.
Consequences worth knowing:
- Defaults live in code, overrides in the database, and text equal to its
default is never stored. Otherwise pressing Save once would freeze
today's wording forever and no later release could improve it.
- An empty override means off. A fragment that was not submitted at all
keeps what it had, because it may be missing from the page only because
whatever contributes it is currently switched off.
- requires= replaced the hand-written pair of memory guidance variants.
The sentence that refers to a section now lives inside that section, so
it cannot outlive it. That was the general problem the pair was a
special case of.
- {{name}}, with anything unrecognised passing through verbatim. The name
grammar is the guard: {"total": 1} and ${PATH} are not candidates.
Substitution is one pass and never recursive, because {{memories}}
carries text a model wrote.
The wording is also overhauled, and a model now gets the core fragments
even with no tools -- the date above all. "An empty harness is worse than
none" was about tokens that say nothing; a model with no clock being asked
about the present is not that. Clearing those boxes restores the old
silence exactly. New: today's date, who it is talking to, the three-round
tool budget, that tool results are not replayed, that anything a tool
returns is data rather than instruction, and what the <document> wrapper
around an attachment is. Extended: memory_forget, notes_edit/delete,
skill_create/edit, and reading a knowledge document in full rather than
answering from an extract.
Tool descriptions stay in code and are listed read-only. They are schema
and they state facts about what a runner does; an edit would make the text
a lie with nothing to catch it.
No schema change -- one JSON row in the settings table.
488 tests. Version 0.2.0, which also invalidates the service worker cache
so the green artwork appears without a hard reload.

Scaffold project, data model and artwork
Establish the LLeMbas foundation: FastAPI/Jinja/SQLite layout, the ORM schema, and the original SVG identity. Notable decisions, all recorded in comments at the point they matter: - No Alembic. SQLite only, schema created at startup, so models carry a few columns nothing reads yet (Message.parent_id for branching, content_parts_json for multimodal turns). Adding them later to a live database without migrations is the painful path. - Sessions are server-side rows keyed by a SHA-256 of the cookie value, not JWTs, so logout and bans revoke access immediately. - Upstream API keys are Fernet-encrypted with a key derived from LEMBAS_SECRET_KEY. decrypt() fails soft to "" so rotating the secret degrades to re-entering keys rather than crashing the admin UI. - Artwork is generated by scripts/build_artwork.py rather than hand-drawn per file: the mallorn leaf appears in the icon, favicon, lockup and banner, and one source is the only way those stay in sync. The wordmark is Source Serif 4 (OFL) converted to outlines, because a README banner cannot load a webfont and <text> would render in whatever serif the viewer happens to have. - Icons live in a template partial, not assets/, because same-document <use href="#id"> is universally supported and the cross-document form is not.
