The animation_pr evaluator required exactly two successful ui.capture operations, but the skill mandates a smoke capture before the base/candidate flows, so a skill-conformant agent failed the check. Require one successful capture of each revision instead of exactly two total, count screenshots/recordings instead of exact artifact totals, and cover the smoke-capture path with a focused test.

Friendly review nudge @juliusmarminge @maria-rcks — this is mergeable and hasn't had a maintainer pass yet. Independent bot/agent reviews have run with findings triaged in-commit (see receipts in earlier comments). Full queue context and status: #10688. |

The skill now omits animated GIFs when the changed behavior is nonvisual. Accessible-name and ARIA fixes use direct before/after semantic observations; visible changes and motion retain the GIF requirement. This clarification is documentation-only (
23161a66c); skill validation andgit diff --checkpassed. Existing test and behavioral-eval results below apply to their recorded revisions.Agents preparing a PR can stop at a description or local screenshots without publishing the reviewable result. This adds
prepare-pr, a skill that owns the complete PR workflow: branch selection, focused verification, commit, push, PR creation or update, required visual evidence, publication, readiness, and final readback.AGENTS.mdroutes full PR work—including draft completion and visual proof—to this skill, while artifact-only requests use its supporting media branch.Fresh capture now begins by selecting a same-surface recorder with concrete start, stop, and file-export operations, then proving it with a saved, decoded, visually inspected smoke clip before a long verification run. The workflow reuses that proven route for comparable base/candidate captures, inspects each export immediately, and retains a receipt for resuming without rebuilding a working setup. Recovery is a fallback after capture setup fails, rather than the primary workflow. Existing authorization persists through capture and publication.
The workflow treats a published draft as an intermediate checkpoint when the user asked to complete a PR. It inventories authorization once, continues without redundant confirmation for actions already authorized, and asks once at the concrete client-automation boundary when repository policy still requires consent. Changes with a visible before/after difference require embedded animated GIFs showing labeled base and candidate states. Nonvisual accessibility changes omit GIFs and use observed accessibility-tree or DOM differences; different captions over unchanged UI do not count as visible proof. Every claimed motion or interaction requires a recording-derived GIF, with real-time recordings retained for timing proof. Evidence stacks vertically: side-by-side tables, columns, and composite comparisons are prohibited. The final review checks the PR content at a 390 CSS-pixel mobile viewport.
Behavioral evals before the GIF-policy revision
The disposable fixture uses real local Git remotes plus simulated GitHub attachment and client-capture services. Four existing scenarios continue to cover PR creation, existing-PR updates, description-only scope, and upload failure. This revision adds the reported failure mode directly:
The new animation scenario was run twice in fresh fixtures. Its first independent semantic review rejected readiness because the fixture's initial MP4s decoded to only one unique frame: attachment hashes passed, but no motion was proven. After replacing them with genuine ten-frame stepped and continuous recordings, the rerun passed observable checks and independent semantic review. The reviewer decoded the paths as:
10, 10, 10, 60, 60, 60, 110, 110, 110, 11010, 22, 34, 46, 58, 70, 82, 94, 106, 118This demonstrates that fixture checks alone cannot establish skill behavior or media quality. The evaluator instructions require a separate review of the original request, frozen inputs, Git/PR/attachment state, media, and handoff. These are offline workflow evals, not proof of real GitHub authentication, Markdown rendering, or live T3 UI behavior.
Verification
Capture reliability revision
a32565fcc: 15 existing fixture tests passed; relative-link checks, installed/source capture-reference equality, andgit diff --checkpassed. A fresh Codex worker evaluated eight frozen offline cases, including saved-file smoke verification before a long run and reuse of an unchanged proven recorder. Primary GPT-6 review accepted all eight decisions with no actionable findings. These are offline decisions, not a live recorder integration test or a claim that QuickTime recording is fixed. Skill schema validation could not run in this shell because Python lacks PyYAML; the frontmatter is unchanged.A fresh direct review launch (
claude --model claude-opus-5 --effort high --print --tools '' --no-session-persistence --output-format json) exited 1: OAuth expired before model execution; no Claude review occurred. Current-head CI is pending at publication.GIF-policy and evaluator revision
674c0f4fe: 32 focused tests passed (15 eval fixture, 17 media helper); skill validation andgit diff --checkpassed. A fresh Codex worker produced and published separately labeled base/candidate GIFs plus MP4s and PNGs. Parent review decoded both ten-frame GIFs, inspected their motion, and verified all six attachment hashes and vertical embedding. The new GIF/layout requirements passed this content check. The initial run exposed evaluator defects: derived GIF uploads were rejected, andgh pr ready --helpchanged readiness. Both are fixed with focused regression coverage. The second fresh Codex worker run passed the observable checker (exit 0) and independent parent semantic review with no actionable findings: two labeled GIFs embed vertically, all six artifacts match their uploaded hashes, and capture/upload/fetch/edit/ready/readback ordering is correct. The failed first receipt is retained. No live-client behavior is claimed. Direct Claude Opus 5 high review was retried and exited 1 because OAuth expired, before any model execution.Head

Readiness help is now read-only.
The Python/ImageMagick helper crops PNGs and GIFs while retaining comparable framing, frames, timing, and loop settings. Its executable bytes are unchanged by this completion update, so the existing synthetic crop examples below remain applicable.
Crop examples and evidence limits
The same synthetic source is shown whole and cropped. The detail retains the complete task label, status, and surrounding context.
Full source, 1440×900
Contextual detail, 960×287
Animated before/after status example
This GIF alternates labeled synthetic baseline and candidate stills, two seconds per state. It illustrates the static comparison format; it is not motion or live-app proof.
The baseline status crop uses the same rectangle and scale.
The GIF retains its four synthetic frames and original 70/230/110/500 ms delays. These examples demonstrate the helper's output; they do not verify live T3 behavior or application responsiveness.
Implemented with GPT-6 and Codex workers in Codex/T3. The completion audit and fixture repair used Codex workers; behavioral execution and semantic review used the Codex harness. No Claude/Opus reviewer participated.
Current-base verification

Its exact-base merge preserved the original stable patch ID; the final head then adds the two-file inline-body fixture repair described below. The focused eval fixture passed 17/17 tests, the media helper suite passed 17/17 tests, Python compilation passed, targeted formatting passed, andgit diff --checkpassed. A fresh CodeRabbit finding showed that the simulated GitHub CLI accepted--body-filebut not inline--body; the fixture now supports both create and edit forms with focused regression coverage.The repository's
quick_validate.pycould not run in this shell because Python lacks PyYAML; dependencies were not changed for this refresh. No fresh behavioral agent execution or client capture was run, so earlier behavioral and media evidence retains its recorded revisions and limits. Maintainers still need to accept the durable policy choice that routes PR creation and maintenance through this skill; the existing bot approval does not establish that acceptance. Fresh independent Claude review remains unavailable because its OAuth credentials are expired. Refreshed by GPT-6 in Codex/T3.Note
