ci: publish a release when a version tag is pushed - #179
Conversation
Push `v1.2.0` and the workflow writes down what went into it and publishes a GitHub release. It deploys nothing — Coolify does that from the server, and CLAUDE.md asks that CI is not given a deploy step. The notes are the commits between this tag and the one before it, grouped the way this repository already talks about its work: New, What was wrong, Faster, Rearranged, Housekeeping. Each line says which part of the platform it touched — "Campus simulator", not "campus" — and links the pull request it came from. Then the numbers, and who wrote it. Anybody whose first commit falls in the range is welcomed by name. Matched on email rather than name, because the same person appears in this history as both `Martian` and `martian56` and welcoming them twice would be worse than not welcoming them at all. Bots are counted out of that entirely, and `Co-authored-by` trailers are credited separately. A tag with a hyphen in the version publishes as a pre-release, by the semver convention, so a release candidate does not become the version people are shown. Re-running the workflow on a tag that already has a release updates its notes rather than failing. The generator is a script with 28 tests rather than a heredoc in the YAML, and those tests run on every pull request. A release happens once and whatever it produces is what people read; finding out then that it welcomed the maintainer as a newcomer is too late. One of those tests exists because the first version could not run at all: the fields were separated by NUL, which is the obvious choice for text a person might type and cannot be passed to git, because an argument is a NUL-terminated string. Nothing about that is visible until something actually shells out. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

📝 WalkthroughWalkthroughThe PR adds a Python release-note generator, unit tests, CI coverage, and a tag-triggered GitHub Actions workflow. The generator parses git history, renders contributor and change summaries, and publishes releases with generated notes. ChangesRelease automation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The new tag-triggered release path places the tag directly into shell code, so a specially crafted tag could execute commands on the CI runner. This creates a high-impact security risk, and the PR is not merge-ready until the tag is passed safely as data. Sequence Diagram(s)sequenceDiagram

In @.github/workflows/release.yml:
- Around line 57-66: Update the “Write the notes” step to pass the release tag
through its env configuration as TAG instead of interpolating it into the shell
script. Use "$TAG" for the release_notes.py argument and printf with "$TAG" when
writing the step summary, preserving the existing notes output.
In `@CLAUDE.md`:
- Around line 163-167: Update the release-notes description in CLAUDE.md to
state that render() groups entries by conventional commit type, while scope is
used only for entry prefixes and the “Where the work went” tally; replace the
inaccurate “grouped by area” wording without changing the surrounding
explanation.

…ly group by
A tag name is chosen by whoever pushes it, and `${{ }}` is substituted before
the shell ever sees the line — so interpolating the tag into the script meant
a tag called
v9.9.9"; touch /tmp/pwned; echo "
would run rather than be passed. Demonstrated both ways round: as written, the
injected command executed; through the environment, the whole thing arrives as
one argument and nothing runs. Every remaining `${{ }}` in the file is in an
`env:` block or the concurrency key, where it is not shell source.
`set -euo pipefail` on the step too, so a generator that fails takes the job
with it rather than publishing an empty release.
And CLAUDE.md described a grouping the code does not do. Sections come from
the conventional-commit *type*; the scope labels each line and is tallied under
"Where the work went". It now says that, including what happens to a subject
that is not conventional at all.

Both sides added the same `.gitignore` rule, for the same reason and within a day of each other: martian56#179 needed `__pycache__` ignored for the release-notes script, and this branch needed it for the same script's bytecode. Kept upstream's — `*.py[cod]` also covers `.pyo` and `.pyd`, and its comment says how the rule relates to `backend/.gitignore`. `CLAUDE.md` merged on its own. Reordered the Deployment section so it still opens by saying what the deployment is before getting to the proxy-hop rule, and added `SECRET_KEY` and `NUM_PROXIES` to the list of what Coolify supplies — both are now required for the backend to start and to rate limit correctly.

That is real output, generated from this repository's actual history.

The first tag says "The first tagged release" and links every commit, rather than comparing against a tag that does not exist.
Why it is a script and not a heredoc
.github/scripts/release_notes.py, with 28 tests that run in CI on every pull request. A release happens once and whatever it produces is what people read — finding out then that it dropped half the commits, or welcomed the maintainer as a newcomer, is too late.One of those tests exists because the first version could not run at all: I separated the fields with NUL, which is the obvious choice for text a person might type, and which cannot be passed to git — an argument is a NUL-terminated string, so Python refuses to build the argv. Nothing about that is visible until something actually shells out, so there is now a test that does.
