Summary

Syncs instruction files with release v0.81.6. Updates documentation for safe-outputs and syntax reference files.

Changes

.github/aw/safe-outputs-automation.md

• Corrected create-code-scanning-alert comment: max field default changed from 40 to unlimited.

.github/aw/safe-outputs-content.md

• Corrected create_issue body maximum length: 65000 → 65536 characters.

.github/aw/safe-outputs-runtime.md

• Added disclosure-header: field under messages config. Prepends an AI authorship disclosure to every message body. Accepts "true" for built-in default text or a custom template string. Supports {workflow_name} and {run_url} placeholders.

.github/aw/syntax-agentic.md

• Expanded on.roles: available values: added maintain and triage roles.
• Documented advanced engine sub-fields: model-provider (github|anthropic|openai), harness (retry policy), engine-level mcp (session-timeout/tool-timeout), extensions, and cwd. References pkg/parser/schemas/main_workflow_schema.json.

.github/aw/syntax-core.md

Hey @app/github-actions 👋 — thanks for this instructions-janitor pass syncing the .github/aw/ instruction files with release v0.81.6! The accuracy fixes (corrected defaults, updated field names) look like a clean, focused maintenance update.

One thing worth noting:

• No test changes — the diff touches .github/aw/*.md instruction files only, with no accompanying test-file updates. If the project has snapshot or lint tests that verify instruction file content or structure, it would be worth confirming they still pass (or adding a check if none exist yet).

Everything else looks solid: the PR is well-scoped to a single concern (syncing docs with a release), has a clear summary with a before/after line-count table, all files remain under the 400-line limit, and the accuracy fixes are verified against source code.

If you'd like a hand adding automated coverage for instruction file validation:

Add a test or lint check that validates .github/aw/*.md instruction files against the following constraints:
1. No file exceeds 400 lines.
2. All documented field names or defaults match their counterparts in the Go source (e.g. pkg/ or internal/).
Place the check where similar doc-linting or snapshot tests live in the repo.

Completed a pr-finisher pass.

• Reviews: no unresolved in-scope review threads/comments requiring code changes.
• Branch freshness: branch is up to date with main (base/head both at 66c9b2f before this PR commit).
• Local checks run: make fmt and make lint passed; make test-unit and make test fail in existing pkg/workflow tests on current HEAD; make recompile completed with no file changes.
• Rerun checks: attempted gh run rerun 29096085435, but this environment returned HTTP 403 for Actions rerun. The current copilot check run is still in progress (https://github.com/github/gh-aw/actions/runs/29096085435/job/86372883261).
