ci: summarize drafted release notes with AI, split release out of test.yml - #3045
Merged
Conversation
…t.yml release-drafter's default template embeds each PR's full body (including CodeRabbit's summary comment) in the draft body; with no .github/auto-release.yml in this repo to trim it, the accumulated draft crossed GitHub's 125,000-character limit and started failing on every push to main. A one-off manual edit doesn't survive: release-drafter recomputes the whole body from merged-PR history on every run, not incrementally. Adds an optional post-processing step (internal/ci/releasenotes + release:summarizeNotes) that condenses each PR's body to one AI-generated sentence via OpenAI, gated cleanly behind an OPENAI_API_KEY secret. Also moves the release job (and this new step) out of test.yml into a workflow_run-triggered release.yml, so a release-notes issue no longer shows up as a "Tests" failure on main.

…ding Ordered-list continuation lines in the new fix-log doc used a 3-space hanging indent (correct CommonMark alignment for "1. ", but not a multiple of 2, which this repo's editorconfig hook requires) - widened to 4. release.yml's secrets: inherit is the same accepted pattern already used by build.yml, feature-release.yml and nightlybuilds.yml calling this same reusable workflow (the called workflow has no workflow_call.secrets: schema, so an explicit map is rejected outright) - added the matching nosemgrep suppression instead of "fixing" a working pattern.

Codecov flagged patch coverage at 75.24% (target 85%), mostly from magefiles/ci_release_notes.go's (Release) SummarizeNotes being entirely untested. Split it the way #3040's ci_rerun.go does: a thin, still-untested env-reading wrapper delegating to a testable summarizeNotes(ctx, stderr, client, params) that holds the actual skip/success/warning branching, now covered by magefiles/ci_release_notes_test.go. summarizeNotes never returns an error by design, so its signature drops the unused return (unparam) instead of suppressing the finding. Also closes real (not synthetic) coverage gaps in internal/ci/releasenotes: a malformed <details> block with no <summary> line, a PR number too large to fit in int, and response bodies that fail mid-read (a real network failure mode, via a shared errReader test helper) - raising package coverage from 92.4% to 95.3%. Left json.Marshal/http.NewRequestWithContext failure branches and SummarizeRelease's unreachable RenderBody-error path uncovered: forcing those would need artificial inputs, not real failure modes. summaryLine's capture group is now non-greedy (.*?): matches the first </summary>, not the last, in the unlikely event a PR title contains that literal substring.

- Line 65: Update the category-heading scan in the release-note parsing logic
around catMatches so headings are considered only within the range after the

…elease notes - ParseDraftedBody now ignores `## ` headings inside a prior PR's own <details> body when assigning the category to the next entry, and rejects a malformed body whose <details>/</details> markers are out of order (equal counts but wrong order previously panicked on a low>high slice). - Summarize now verifies each OpenAI response entry's PR number matches the entry sent at that position, instead of trusting index order, so a reordered model response can't attach a summary to the wrong PR. - Terminate two inline test comments with periods per godot. Addresses CodeRabbit review threads on PR #3045. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…dry run Validated live against a real release for the first time, which surfaced three things: - The renderer flattened entries to bullets. The point of summarization is to keep release-drafter's collapsible <details><summary>title @author (#N)</summary> blocks and shrink only the hidden body, so RenderBody now emits exactly the change-template shape; a round-trip test (render -> ParseDraftedBody -> same entries) pins it. - The coded default model (gpt-5.6-luna) returned 403 model_not_found for the cloudposse OpenAI project, whose newest reachable models are the gpt-5.4 line. Default is now gpt-5-mini (OPENAI_MODEL overrides). - temperature: 0.3 returned 400 unsupported_value on the gpt-5 family; the request no longer sends temperature. RELEASE_NOTES_DRY_RUN=1 prints the summarized body instead of updating the release, so the result can be previewed against any real release. Live result on v1.228.0-rc.2: 9,763 -> 1,072 chars, structure intact. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The 403 model_not_found was a project permission, not a missing model: once the cloudposse OpenAI project was granted the 5.6 models the same call flapped between 403 and success for several minutes while the grant propagated, then a dry-run against v1.228.0-rc.2 succeeded (9,763 -> 859 chars, details blocks and headings intact). A 403 here is a project setting to fix; the job's log-and-skip already covers the propagation window. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…se body Reading the drafted release back could never fix the incident: there is no hook between release-drafter computing a body and writing it, so once the org template's full-body embed passes 125,000 characters the draft cannot be written and nothing downstream runs - and every later run recomputes the full body again. A repo-level .github/auto-release.yml keeps the org's categories and version resolution but reduces change-template to a skeleton bullet per PR, which never approaches the limit. summarize-notes then fetches each PR's description from the pull-request API (no such cap), condenses it, and rewrites the release in the org template's exact <details> shape with the condensed text as each block's body. - With OPENAI_API_KEY the model condenses; without it each entry gets CodeRabbit's own summary block when present, else a 1,200-char truncated description. The job always runs and never fails the release; the skeleton is readable notes on its own. - If even the summarized body exceeds 120k the release falls back to the bare skeleton bullets. - The parser accepts both the skeleton and the org <details> shape. - release.yml: summarize-notes gains pull-requests: read. Validated live against the real v1.228.0 draft (19 PRs): 19 PR fetches, one model call, 19 details blocks under 2 headings in 4,420 chars. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…rs in details One sentence per PR was too little to justify expanding a block. The model now writes 3-6 Markdown bullets (about 60-150 words) that keep what changed and why with the concrete command/flag/config names, fed up to 6k characters of each description instead of 2k. A line starting with <details> opens a GFM HTML block that swallows everything up to the next blank line as raw HTML, so the summary line's Markdown (dependabot's author link, backticks) and the body rendered raw. RenderBody now puts blank lines after <details>, around the body, and before </details>. Live on the v1.228.0 draft: 19 entries, 8,430 chars. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Demanding 3-6 bullets made the model pad single-change PRs with three restatements of the title. The prompt now asks for one bullet per distinct change (a small PR gets one, a large one at most six), forbids restating the title or saying the same thing twice, drops generic benefit sentences, and caps rather than floors the length. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The previous prompt made the model collapse multi-change PRs into one comma-joined sentence. It now defines a distinct change (a separately usable capability, command, flag, config key, behavior, or fixed bug), points at the description's own 'what' list and 'Add X, fix Y' titles as the count, and forbids merging distinct changes into one bullet. Single-change PRs and dependency bumps still get one bullet. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…pics One bullet per distinct change atomized related details into parallel stub sentences with the same subject. The prompt now asks for how an engineer writes release notes: one to three sentences of prose that fold related details into a natural list, bullets only when a PR spans separate topics, with one example of each shape and an 80-word cap. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Flush-left prose under a <summary> line is visually indistinguishable from the heading; the indent is what makes the notes scannable. The prompt now asks for one bullet per topic (a single-topic PR is one bullet of one to three sentences), and the renderer guarantees the layout by turning any paragraph that is not already a list item into one, so it never depends on the model's formatting choice. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The org release-drafter categories know enhancement/patch/fix/auto-update and file patch under Enhancements, while this repo labels PRs major/minor/patch/no-release: fixes read as enhancements, no Bug Fixes chapter ever appeared, and every minor feature sat uncategorized at the top with no heading. The repo config now maps major -> Breaking Changes, minor -> Features, patch -> Bug Fixes. The renderer gives any still-uncategorized group an Other Changes heading when the release has categorized groups, and converts the <summary> line's Markdown (bot author links, backticks) to HTML: blank lines make the body render, but GitHub never renders Markdown inside the summary tag itself.

release.yml lacked a concurrency group, so two Tests runs finishing close together could race summarize-notes' read-modify-write of the same draft release and clobber each other's rewrite. Add a release-wide concurrency group with cancel-in-progress: false so overlapping runs queue instead. SummarizeRelease's bare-bullet fallback (used when the summarized body still exceeds the size limit) was never itself checked against the limit before being handed to UpdateReleaseBody. Extract the degrade step into degradeIfTooLarge and return a clear error instead of attempting an oversized update, with a regression test for the still-too-large case.

what
release / draft / releasefailing on every push tomainwithbody is too long (maximum is 125000 characters)..github/auto-release.yml(the org config withchange-templatereduced to- $TITLE @$AUTHOR (#$NUMBER), and categories that match this repo's actual labels:major→ Breaking Changes,minor→ Features,patch→ Bug Fixes - the org config filedpatchunder Enhancements and knew nominor, so fixes read as enhancements, no Bug Fixes chapter ever appeared, and features sat uncategorized at the top with no heading) plus aninternal/ci/releasenotespackage andrelease:summarizeNotesmage target. There is no hook between release-drafter computing a body and writing it, so once the org template's full-body embed passes 125,000 characters the draft cannot be written and nothing downstream can run - reading the drafted body back is not a workable source. Release-drafter now only writes the skeleton (never near the limit);summarize-notesthen fetches each PR's description from the pull-request API (no such cap), condenses it, and rewrites the release in the org template's exact shape - the same category headings and collapsible<details><summary>title @author (#N)</summary>block per PR - with the condensed text as each block's body: one to three sentences of plain prose saying what changed and, when the description says so, why, naming the concrete commands/flags/config keys; bullets only when a PR spans separate, unrelated topics, one full sentence per topic (tuned live on the draft: one sentence per PR was too little, forced bullet counts padded or atomized). The<summary>line's Markdown (bot author links, backticks) is converted to HTML, since GitHub never renders Markdown inside that tag; any still-uncategorized group gets an "Other Changes" heading when the release has categorized groups. Blank lines inside each block are load-bearing: a<details>line opens a GFM HTML block that swallows everything up to the next blank line as raw HTML, so without them the summary line's Markdown (dependabot's author link, backticks) rendered raw. The notes read and expand as before; only the hidden part is short.OPENAI_API_KEYthe condensing is done by the model (defaultgpt-5.6-luna, overridable withOPENAI_MODEL); without it each entry gets CodeRabbit's own summary block when present, else a 1,200-character truncated description. If even that exceeds 120k the release falls back to the bare skeleton bullets. Any API failure is logged, never fails the job: the skeleton is readable notes on its own.RELEASE_NOTES_DRY_RUN=1prints the rewritten body instead of updating the release, for previewing against any real release.v1.228.0draft (19 PRs, skeleton body): 19 PR fetches, one model call, 19<details>blocks under 2 headings in 8,430 characters, then written to the draft itself and checked in the UI. Earlier live attempts surfaced one real defect, fixed here (a non-defaulttemperaturereturns400 unsupported_valueon the gpt-5 family, so none is sent) and one project setting (gpt-5.6-lunareturned403 model_not_founduntil the cloudposse OpenAI project was granted the 5.6 models, then flapped for several minutes while the grant propagated; the job's log-and-skip covers that window).release:job (and this new step) out oftest.ymlinto a newworkflow_run-triggered.github/workflows/release.yml, so a release-notes issue no longer shows up as a "Tests" failure onmain.

cloudposse/atmoshas no.github/auto-release.yml(confirmed againstmainvia the GitHub API - every other CloudPosse repo checked has one). With no repo config, release-drafter falls back to achange-templatethat embeds each PR's full body, including CodeRabbit's auto-generated summary comment, inside a<details>block. The draft forv1.228.0was already 56KB across 23 PRs and kept growing every merge until it crossed GitHub's 125,000-character limit.A manual edit of the release body doesn't survive a rerun: release-drafter recomputes the entire body from merged-PR history from scratch every time, not incrementally - confirmed empirically by trimming the release via the API and rerunning the same failed job, which reproduced the identical error.
