GitHub Agentic Workflows Files

🌟 Release Highlights

This release brings significant security hardening, new authentication options, expanded model support, and important workflow reliability fixes across the gh-aw platform.

✨ What's New

• Google Vertex AI Workload Identity Federation — Authenticate to Google AI via Workload Identity Federation, eliminating the need for long-lived service account keys in Gemini-powered workflows. (#48185)
• Safe-output field aliases — New field aliases enable precise agent mistake detection, making it easier to catch and surface incorrect safe-output usage patterns. (#48230)
• Copilot BYOK frontmatter options — Expose extraHeaders, extraBodyFields, and sessionId in workflow frontmatter for bring-your-own-key Copilot SDK integrations. (#48096)
• stringsindexhasprefix Go linter — New analyzer detects strings.Index(...) == 0 patterns that should use strings.HasPrefix. (#48049)
• PolicyCompiler.Compile + attribution compliance tests — Formal intent-based policy compilation with a full attribution compliance test suite. (#48036)
• Model inventory update — Added claude-opus-5 to pricing catalogs and kept all model mirrors in sync. (#48294, #48279, #48303)
• AWF & MCP Gateway bumped — Default AWF v0.27.42 / MCP Gateway v0.4.6 with refreshed pinned artifacts. (#48236)

🐛 Bug Fixes & Improvements

• Secret argv exposure mitigated — Hardened remote include write boundaries to prevent accidental secret leakage via process arguments. (#48318)
• dispatch_workflow backward compatibility restored — Single-target dispatch safe outputs work again after the multi-target refactor. (#48317)
• add-wizard bootstrap ordering fixed — Pre-install bootstrap steps now run before engine selection, and call-workflow worker loading is properly initialized. (#48282, #48301)
• MCP CLI stdin mode corrected — Per-field stdin mode now correctly extracts the target JSON field value instead of passing the raw JSON string. (#48100)
• GH_AW_INPUT_* forwarded to MCP container — Dynamic safe-outputs configuration now reaches the MCP container environment as intended. (#48099)
• label_command activation guard preserved — Custom if: conditions in frontmatter no longer clobber the built-in activation guard. (#48105)
• HTTPS angle-bracket autolinks preserved — Safe-output sanitization no longer strips valid (redacted) autolinks. (#48169)
• Playwright CI sandbox flag — Chromium sandbox disabled for playwright-cli mode in CI containers, fixing test failures in rootless environments. (#48102)
• Deduplication rate-limit guard fixed — The deduplicate-by-title guard was always skipping due to a wrong bucket threshold comparison. (#48092)
• CI reliability — Resolved empty-SHA cache entries, stale action pins, and P0 CI failures. (#48291)
• Goroutine lifecycle bounded — Added join handle for StartDockerImageDownload to prevent goroutine leaks. (#47974)
• PR diff prefetch caching — Reduced redundant PR diff/file-list API reads with head-SHA-aware caching in top review workflows. (#47997)
• Repo-memory patch-size cap raised — Prevents Agent Performance Analyzer push failures on large diffs. (#48012, #48106)

📚 Documentation

• Added release workflow pattern instructions and strengthened compliance trigger guidance with non-technical persona examples.
• Consolidated developer specifications into a single instructions file (v9.22).
• Added GEO-compliant AI discovery endpoints to the docs site.
• Unbloated the artifacts and templating reference pages for easier scanning.
