## The problem
AI PRs write comments that restate the line below them, mark sections
with box drawing, and narrate the diff. Nothing in the repo said not to,
and nothing checked. `AGENTS.md` had one line about comments and it was
buried in the Python section.
Banners and `Step N:` narration have zero occurrences in the 15 months
before Aug 2025, so this is new.
## The fix
A written standard, plus a linter that enforces the mechanical part of
it on added lines only.
-
[devGuide/CODE_COMMENTS.md](https://github.com/Stirling-Tools/Stirling-PDF/blob/claude/ai-pr-comment-quality-dd970e/devGuide/CODE_COMMENTS.md)
holds the reasoning and worked examples; a section in
[AGENTS.md](https://github.com/Stirling-Tools/Stirling-PDF/blob/claude/ai-pr-comment-quality-dd970e/AGENTS.md)
holds the operative rules, kept short so they stay in an agent's
context. The two are split by kind rather than duplicated, because the
same prose in two places drifts.
- Rules in
[comment-rules.mjs](https://github.com/Stirling-Tools/Stirling-PDF/blob/claude/ai-pr-comment-quality-dd970e/scripts/lint/comment-rules.mjs),
shared by both engines.
- Two engines. `.ts` / `.tsx` / `.mjs` go to an [oxlint JS
plugin](https://github.com/Stirling-Tools/Stirling-PDF/blob/claude/ai-pr-comment-quality-dd970e/scripts/lint/comment-lint-oxlint-plugin.mjs)
so comments come from the parser rather than a line scan; `.java` /
`.py` go to a [line
scanner](https://github.com/Stirling-Tools/Stirling-PDF/blob/claude/ai-pr-comment-quality-dd970e/scripts/lint/comment-lint.mjs).
Neither reads the other's files, so they cannot disagree about one file.
- Between them they read every comment form the repo writes: `//` and
`/* */`, Javadoc and JSDoc, JSX comments, `#`, and Python docstrings.
- Runs in `task pre-commit`, so the git hook and the `pre_commit.yml` CI
job both get it, and as a Claude Code [`Stop`
hook](https://github.com/Stirling-Tools/Stirling-PDF/blob/claude/ai-pr-comment-quality-dd970e/scripts/lint/comment-lint-hook.mjs)
so an agent fixes the comment inside the turn that wrote it.
## The rules
The part worth arguing about. **Every rule blocks.** A rule that only
warns is a rule nobody acts on, so a finding you believe is wrong is a
bug in the rule: narrow it, or mark the line and say why.

Each rule carries the readings it deliberately excludes, next to the
rule. Those exclusions came from running the rules over this repo, not
from taste: `CMT004` does not match a bare "no longer needed" because
that is as often about runtime lifecycle as about history, and `CMT003`
needs a separator after the number so a wrapped line beginning "step 2
unmounts + remounts the panel" reads as the prose it is.
A comment sharing a line with code is judged by the rules that do not
depend on the code below it, so a trailing `// TODO fix this` or `/*
this used to run before the flush */` still reports, while `50L * 1024 *
1024 // 50 MB` does not. `CMT001` would have been wrong about six in
seven trailing comments here, so it stays out of them.
If a finding is wrong, `// comment-lint-allow: CMT002` on the line
above. Rule-specific, [no blanket
disable](https://github.com/Stirling-Tools/Stirling-PDF/blob/claude/ai-pr-comment-quality-dd970e/scripts/lint/comment-rules.mjs#L229).
A directive naming a rule that does not exist, or silencing nothing, is
itself a `CMT008` failure, so a typo cannot quietly disable a rule and a
stale one gets deleted rather than accumulating.
No native linter covers `CMT007`. `eslint-plugin-jsdoc`'s
`require-param-description`, Checkstyle's `NonEmptyAtclauseDescription`
and ruff's D-rules all check that a description exists, not whether it
says anything.
## Scoping
Added comment **text** only, not lines git calls new. Reindenting a file
or moving a block makes git mark untouched comments as added; findings
are matched against the comment text at the base, so only genuinely new
content reports.
The whole file is read and every comment in it evaluated. Only the
*reporting* is filtered, so a rule still sees the code a comment
introduces, the full run it belongs to, and the base version of the
file.
Existing tree is untouched. `task pre-commit:comment-lint:all` reports
it and always exits 0:
| | java | ts/js | py |
| --- | --- | --- | --- |
| findings | 1,218 | 741 | 204 |
2,163 across 542 files, mostly `CMT002` banners (1,482) and `CMT001`
restatements (456). Clearing it is separate work, by directory.
Not in this PR: an advisory LLM review layer for the things no pattern
can judge.
## Verification
Run against
[#7494](https://github.com/Stirling-Tools/Stirling-PDF/pull/7494) as CI
would, in a throwaway worktree: **two findings on a 78 file, +4,512 line
change, both genuine banners, in 952ms**. A whole-file scan of those
same files gives 11; the other 9 were withheld because that PR's author
did not write them, and they are the `@param teamId the team ID` shape
this standard exists to stop.
Both scanners blank string and character literals before looking for
comment markers, because a partial lex desynchronises everything after
it: one apostrophe in a Java comment, or one Python template whose
closing quotes start a line, is enough to read dozens of lines of code
as a single comment. Two fixtures carry canaries that stop being
reported if either engine ever desynchronises again.
The [fixture
corpus](https://github.com/Stirling-Tools/Stirling-PDF/tree/claude/ai-pr-comment-quality-dd970e/scripts/lint/fixtures)
pins all 9 rules against both engines, and `--selftest` fails if the two
disagree about the same file.
## Two things reviewers should know
**The oxlint JS plugin API is alpha.** oxlint itself is stable and
already this repo's frontend linter; the plugin API is the new
dependency. Its documented failure mode
([oxc#25203](https://github.com/oxc-project/oxc/issues/25203)) is being
skipped silently while oxlint still reports success. That affects the
standalone release binary rather than the npm package this invokes, but
the class of failure reads exactly like clean code, so the run asserts
`number_of_rules >= 1` from oxlint's own report and a broken engine
exits 2 rather than passing. If the API ever breaks, the fallback is
folding these rules into the line scanner, which already implements all
nine for Java and Python.
**`.claude/settings.json` is now committed**, carrying the hook and
nothing else: 19 lines, no `permissions`, nothing machine-specific. That
partly reverts `c35546a212` ("Ignore claude dir"), which existed because
this file had twice been committed by accident with a personal
`permissions` allowlist, once with absolute machine paths. Personal
config still belongs in `.claude/settings.local.json`, which the new
pattern keeps ignored, and hook entries merge across the two so nobody's
own hooks are lost.
If you already hand-wrote a `.claude/settings.json`, copy it somewhere
first: that path used to be git-ignored, and git overwrites an ignored
file without warning when a commit starts tracking it. Across 19 local
checkouts here, 13 have `settings.local.json` and none has a
hand-written `settings.json`.
To turn the hook off, `{ "env": { "COMMENT_LINT_HOOK": "0" } }` in local
settings. Claude Code can only disable all hooks at once, hence the
switch. The commit-time gate still applies.
## How to test
```bash
task pre-commit:comment-lint:ci
```
The fixture corpus, then the diff. The corpus checks the rules
themselves rather than the code under review, so it runs on CI and
before a rule change, not on every local commit.
```bash
task comment-lint:branch
```
`clean (34 files in scope)`. `task comment-lint` is the same thing
scoped to uncommitted work, which is what the git hook and CI run.
To watch it bite, add `// Is banner` above `export function isBanner` in
`scripts/lint/comment-rules.mjs` and run `task comment-lint`: one
`CMT001`, exit 1. The gate covers its own source, which is why these
scripts have no section dividers.
```bash
task pre-commit:comment-lint:all
```
The standing backlog, report-only.
Verified on the pinned oxlint 1.77.0, not only the 1.79 the plugin was
prototyped against.
# Description of Changes
Smaller scope than #6689 to try and get this finished.
Replace ESLint and dpdm with Oxlint, a TS linter written in Rust so its
performance is dramatically better than the existing tools we use.
## Speed improvement
- Current ESLint run: 13.76s
- Current dpdm run: 3.59s
- Total time: 17.35s
- New Oxlint run: 0.90s
So Oxlint is about a 20x speed improvement.
## Differences
When I last tried to do this, we could recreate our rules identically
with Oxlint, but that's not true any more. Oxlint has no current
equivalent for ESLint's `no-restricted-syntax` rule, which we were using
to ban usages of `<button>` and stuff in specific components to try and
encourage them to use our shared UI. This is a very recent addition to
our linting config, and personally I'm willing to drop it for now at
least. We can still ban specific imports in files, so the files which we
were trying to enforce shared UI will still ban directly importing
Mantine, so that'll probably be most of the cases still caught, but I
think there are other ways we can encourage using the shared UI beyond
just using the linter for it.
I did try building a custom TS rule for it and it only slowed it down a
tiny bit (it took 1.1s) but it had to be built on an unreleased alpha
API which just sounds like a maintenance headache we don't need to deal
with for a rule that we don't really need.
## What this does
Consolidates the frontend's colour/theme system into a small,
well-defined token layer and reworks the theme picker. The goal was a
minimal, scalable set of semantic tokens that the editor **and** the
Processor/portal (and Storybook) all share, plus a theme model that's
easy to reason about.
## Token architecture (`core/theme/`)
A four-file layer, imported once via `index.css`:
| File | Role |
|---|---|
| `primitives.css` | The raw palette — the **only** place literal
colours live (neutral ramps `--p-gray-*`/`--p-zinc-*` + status hues). |
| `colors.css` | ~21 semantic `--c-*` tokens (surfaces, text, borders,
primary, status) mapped from primitives per theme. **Reference these.**
|
| `compat.css` | Legacy names (`--bg-*`, `--text-*`, `--color-*`)
aliased onto `--c-*` via `:root:root` so ~200 existing files keep
working. |
| `dimensions.css` | All non-colour tokens (spacing, radius, z-index,
type, motion) — single source, resolving prior collisions. |
A blocking linter (`scripts/lint/theme-lint.mjs`, run in
`frontend:lint`) enforces "literals only in `primitives.css`" within
`core/theme/`, and has a non-blocking WCAG contrast report. See
`core/theme/README.md`.
## Theme model
- **Mode** (`light` / `dark` / `system`) and **accent** are independent.
Each mode has its own accent (`lightPrimary` / `darkPrimary`).
- The editor is always `data-app-theme="custom"`; `ThemeProvider`
injects the accent as `--user-primary` and sets `data-accent`.
- **Two accent states:**
- A **colour** (preset or custom hex) → tints every surface that hue
(whole-app theming).
- The **`default`** sentinel → neutral surfaces (white/grey light, zinc
black/grey dark) with blue buttons, no tint. (`data-accent="default"`
opts surfaces out of the tint.)
- Accent contrast guardrails (`utils/customPrimary.ts`): lightness
clamps so an accent can't collapse into the base, a contrast-picked
on-primary foreground, and an accent-as-foreground variant so accent
text is never dark-on-dark.
## Theme picker (Settings → General)
- 3×5 grid: a distinct **Default** icon chip (not a colour) + 14 curated
accents, in a dropdown per mode.
- **Custom** colour via the shared `ColorInput`, with a live gamut clamp
(`clampValue`) that refuses white/grey/black — the picker handle sticks
at the boundary and preserves the working hue at achromatic extremes.
- "Restore theme to default" resets both modes.
## Other
- Dark mode is a true neutral zinc (no navy "midnight" tint); the
Mantine dark ramp and Tailwind dark channels were neutralised to match.
- Pre-paint inline script in `index.html` applies theme + accent before
first paint (no FOUC); portal and editor now share the same
`preferences.theme` source of truth.
- High-visibility surfaces migrated to tokens (FAB, landing upload
buttons, portal hero banners); scattered per-component colour swaps were
intentionally **left for a follow-up** to keep this PR focused.
## Testing
- `task frontend:check:all` (typecheck all variants + eslint + prettier
+ colour-lint) green.
- Verified light/dark, default vs tinted accents, and the custom clamp
via computed styles in the dev preview.
> Note: the `prerender-og` build step failing in the e2e/deploy jobs is
unrelated to this diff — it's in `vite.config.ts` (untouched here) and
builds cleanly locally.
# Description of Changes
Replaces the `.stirling/done` folder and its friends with a ledger in
the DB which tracks which documents have been processed. This should
scale dramatically better since it's just a few bytes being written for
each PDF processed, rather than each PDF being duplicated and held in
the folder forever. It's designed to work with the current folder
source, but also with S3 buckets and other sources in mind - each source
will define its own strategy for ensuring it knows whether the documents
have had policies run on them or not, and they all get written to the
same ledger.
# Description of Changes
We don't have any strong reasons to keep the Portal as a separate Vite
app, and it needs access to so many things from the Editor that it no
longer makes sense to keep them separate. This PR moves the Portal code
to have direct access to the Editor code and gets rid of the shared
folder.
# Description of Changes
#6727 introduced frontend code which goes against the architecture, so
this PR re-implements it in the architecture properly, along with
another bad Tauri check that I found in the source. I also updated the
`AGENTS.md` file to use Claude's "read this file" syntax to try and
force AI to actually read the file instead of just suggesting that it
does it.
## What & why
Chained on top of #6649 (the `cloud/` refactor). The AI assistant was
effectively dead on desktop:
1. **Hidden** — `ChatFAB` gates on `aiEngineEnabled`, which desktop
reads from the **local** bundled backend's `/api/v1/config/app-config`.
The local backend has no AI engine, so the flag is always `false` and
the FAB never renders.
2. **Mis-routed** — even if shown, AI calls used `getApiBaseUrl()`,
which is empty/local on desktop, so the orchestrate stream and AI
result-file download missed the engine (which only runs in the cloud).
This PR wires AI properly **without hardcoding it on**, so the cloud
keeps the kill switch: flip `aiEngineEnabled` server-side and the
desktop FAB disappears on the next load — no desktop release required.
(Deliberately *not* assume-on, so a future "turn AI off" doesn't strand
shipped versions.)
## Changes
**General SaaS app-config service** (reusable for any cloud flag, not
just AI):
- `desktop/services/saasAppConfigService.ts` — SaaS-mode-only fetch +
5-min cache of the **public** `/api/v1/config/app-config` from the
**SaaS** backend over native HTTP (`@tauri-apps/plugin-http`, no CORS).
Returns `null` outside SaaS mode.
- `desktop/hooks/useSaasAppConfig.ts` — hook over it; reloads on
connection-mode change.
**AI gating + routing seams:**
- `useAiEngineEnabled()` — core reads `useAppConfig()` (web), desktop
reads `useSaasAppConfig()`. `ChatFAB` consumes it.
- `getAiBaseUrl()` — core uses the normal API base (web), desktop points
AI calls at the SaaS backend. `ChatContext` uses it for the orchestrate
stream + result-file download.
- `operationRouter` — route `/api/v1/ai/*` to the SaaS backend
(cloud-only prefix).
**Docs:** AGENTS.md gains a short "cloud feature flags on desktop" note
so the pattern is maintained.
## Verification
- `tsc --noEmit` green for saas / desktop / cloud flavors
- `eslint --max-warnings=0` clean (cloud-layer guardrail respected — the
platform-coupled bits live in `desktop/`)
- New `saasAppConfigService.test.ts` (3 tests) + existing
`operationRouter` / `tauriHttpClient` / `httpErrorHandler` suites green
- 0 stray compiled artifacts
## Not headlessly verifiable — needs a live Tauri smoke
The orchestrate **SSE stream** uses the webview's global `fetch` (native
HTTP can't stream the body the same way), so it's subject to browser
CORS to the SaaS backend. The `SupabaseSecurityConfig` tauri-origin
allowance (from #6649) covers it, but please confirm on a real build:
open the FAB in SaaS mode, run an agent task, watch the stream + a
result-file download succeed.
# Description of Changes
Redesign AI engine so that it autogenerates the `tool_models.py` file
from the OpenAPI spec so the Python has access to the Java API
parameters and the full list of Java tools that it can run. CI ensures
that whenever someone modifies a tool endpoint that the AI enigne tool
models get updated as well (the dev gets told to run `task
engine:tool-models`).
There's loads of advantages to having the Java be the one that actually
executes the tools, rather than the frontend as it was previously set up
to theoretically use:
- The AI gets much better descriptions of the params from the API docs
- It'll be usable headless in the future so a Java daemon could run to
execute ops on files in a folder without the need for the UI to run
- The Java already has all the logic it needs to execute the tools
- We don't need to parse the TypeScript to find the API (which is hard
because the TS wasn't designed to be computer-read to extract the API)
I've also hooked up the prototype frontend to ensure it's working
properly, and have built it in a way that all the tool names can be
translated properly, which was always an issue with previous prototypes
of this.

## Add Taskfile for unified dev workflow
### Summary
- Introduces [Taskfile](https://taskfile.dev/) as the single CLI entry
point for all development workflows across backend, frontend, engine,
Docker, and desktop
- ~80 tasks organized into 6 namespaces: `backend:`, `frontend:`,
`engine:`, `docker:`, `desktop:`, plus root-level composites
- All CI workflows migrated to use Task
- Deletes `engine/Makefile` and `scripts/build-tauri-jlink.{sh,bat}` —
replaced by Task equivalents
- Removes redundant npm scripts (`dev`, `build`, `prep`, `lint`, `test`,
`typecheck:all`) from `package.json`
- Smart dependency caching: `sources`/`status`/`generates`
fingerprinting, CI-aware `npm ci` vs `npm install`, `run: once` for
parallel dep deduplication
### What this does NOT do
- Does not replace Gradle, npm, or Docker — Taskfile is a thin
orchestration wrapper
- Does not change application code or behavior
### Install
```
npm install -g @go-task/cli # or: brew install go-task, winget install Task.Task
```
### Quick start
```
task --list # discover all tasks
task install # install all deps
task dev # start backend + frontend
task dev:all # also start AI engine
task test # run all tests
task check # quick quality gate (local dev)
task check:all # full CI quality gate
```
### Test plan
- [ ] Install `task` CLI and run `task --list` — verify all tasks
display
- [ ] Run `task install` — verify frontend + engine deps install
- [ ] Run `task dev` — verify backend + frontend start, Ctrl+C exits
cleanly
- [ ] Run `task frontend:check` — verify typecheck + lint + test pass
- [ ] Run `task desktop:dev` — verify jlink builds are cached on second
run
- [ ] Verify CI passes on all workflows

# Description of Changes
Redesign the Python AI engine to be properly agentic and make use of
`pydantic-ai` instead of `langchain` for correctness and ergonomics.
This should be a good foundation for us to build our AI engine on going
forwards.
# Description of Changes
Add frontend developer guide describing the path alias architecture.
There's probably more needed in here which we should flesh out over
time, but this is a start.
# Description of Changes
Previously, `VITE_*` environment variables were scattered across the
codebase with hardcoded fallback values inline (e.g.
`import.meta.env.VITE_STRIPE_KEY || 'pk_live_...'`). This made it
unclear which variables
were required, what they were for, and caused real keys to be silently
used in builds where they hadn't been explicitly configured.
## What's changed
I've added `frontend/.env.example` and `frontend/.env.desktop.example`,
which declare every `VITE_*` variable the app uses, with comments
explaining each one and sensible defaults where applicable. These
are the source of truth for what's required.
I've added a setup script which runs before `npm run dev`, `build`,
`tauri-dev`, and all `tauri-build*` commands. It:
- Creates your local `.env` / `.env.desktop` from the example files on
first run, so you don't need to do anything manually
- Errors if you're missing keys that the example defines (e.g. after
pulling changes that added a new variable). These can either be
manually-set env vars, or in your `.env` file (env vars take precedence
over `.env` file vars when running)
- Warns if you have `VITE_*` variables set in your environment that
aren't listed in any example file
I've removed all `|| 'hardcoded-value'` defaults from source files
because they are not necessary in this system, as all variables must be
explicitly set (they can be set to `VITE_ENV_VAR=`, just as long as the
variable actually exists). I think this system will make it really
obvious exactly what you need to set and what's actually running in the
code.
I've added a test that checks that every `import.meta.env.VITE_*`
reference found in source is present in at least one example file, so
new variables can't be added without being documented.
## For contributors
New contributors shouldn't need to do anything - `npm run dev` will
create your `.env` automatically.
If you already have a `.env` file in the `frontend/` folder, you may
well need to update it to make the system happy. Here's an example
output from running `npm run dev` with an old `.env` file:
```
$ npm run dev
> frontend@0.1.0 dev
> npm run prep && vite
> frontend@0.1.0 prep
> tsx scripts/setup-env.ts && npm run generate-icons
setup-env: see frontend/README.md#environment-variables for documentation
setup-env: .env is missing keys from config/.env.example:
VITE_GOOGLE_DRIVE_CLIENT_ID
VITE_GOOGLE_DRIVE_API_KEY
VITE_GOOGLE_DRIVE_APP_ID
VITE_PUBLIC_POSTHOG_KEY
VITE_PUBLIC_POSTHOG_HOST
Add them manually or delete your local file to re-copy from the example.
setup-env: the following VITE_ vars are set but not listed in any example file:
VITE_DEV_BYPASS_AUTH
Add them to config/.env.example or config/.env.desktop.example if they are required.
```
If you add a new `VITE_*` variable to the codebase, add it to the
appropriate `frontend/config/.env.example` file or the test will fail.
# Description of Changes
Inspired by https://github.com/pydantic/pydantic-ai/pull/4169, this PR
moves our `CLAUDE.md` advice to the more generic `AGENTS.md` file (which
works on Codex, Gemini, etc). It also adds a symlink from `CLAUDE.md` to
`AGENTS.md`, which Claude follows properly, so all AIs should get the
same advice and we only need to keep one file up-to-date.
# Description of Changes
This pull request introduces several improvements to enhance error
handling, internationalization, and documentation in the codebase. The
key changes include the addition of `ExceptionUtils` and `I18nUtils`
utility classes for consistent exception handling and internationalized
messages, updates to documentation paths, and modifications to existing
methods to integrate the new utilities.
### Error Handling Enhancements:
* **Added `ExceptionUtils` utility class**: Provides standardized
methods for creating and handling exceptions with internationalized
error messages, including specific handling for PDF corruption,
encryption issues, and other file-related errors.
* **Integrated `ExceptionUtils` into `CustomPDFDocumentFactory`**:
Updated `loadFromFile` and `loadFromBytes` methods to log and handle
exceptions using `ExceptionUtils`, ensuring consistent error handling

* **Updated `FileToPdf` to use `ExceptionUtils`**: Replaced direct
exception throwing with `ExceptionUtils.createHtmlFileRequiredException`
for unsupported file formats.
### Internationalization Improvements:
* **Added `I18nUtils` utility class**: Centralized access to Spring's
`MessageSource` for retrieving localized messages, enabling consistent
internationalization across the application.
### Documentation Updates:
* **Updated documentation paths in `CONTRIBUTING.md` and `README.md`**:
Changed paths to reference the new `devGuide` folder for developer
documentation and translation guides.
