🌟 Release Highlights

This release strengthens reliability, developer experience, and observability with daily automated reviews, improved error messages, and enhanced telemetry instrumentation.

✨ What's New

🔍 Daily Reliability Review — A new scheduled workflow automatically detects and reports gh-aw reliability issues using Sentry observability data, querying for failures, timeouts, cancellations, and token truncations. The workflow creates prioritized findings with actionable recommendations, helping maintainers catch issues early. (#33493)

💡 Fuzzy "Did You Mean?" Suggestions — Validation errors now include helpful suggestions when you mistype engine names, events, permissions, or MCP types (e.g., invalid engine: copiliot → Did you mean: copilot?). The feature uses Levenshtein distance matching to catch common typos during compilation. (#33467)

📍 File/Line Context in Validation Errors — Validation errors now show file:line:col: positioning so IDE tooling can jump directly to the problematic field, eliminating manual searches through workflow files. (#33466)

💭 Reasoning Message Rendering — Reasoning content (Claude extended thinking blocks, Codex thinking sections, Copilot reasoning_text) now renders with a distinct ◯ open circle icon and italic styling, making agent thought processes visible and distinguishable from regular output. (#33464)

🐛 Bug Fixes & Improvements

Telemetry Instrumentation — Fixed four critical OTLP gaps: service.version fallback to GITHUB_SHA, gen_ai.response.finish_reasons always emitted, timeouts distinguished from failures, and gen_ai.usage.total_tokens now tracked. (#33528, #33510)

Network Access — Added patch-diff.githubusercontent.com to the GitHub domain ecosystem, allowing workflows using network.allowed: [github] to fetch PR diffs without blocking. (#33543)

Linter Improvements — Enhanced analyzer ergonomics with ctxbackground autofix, consistent test-file handling, and range-based diagnostics for better IDE integration. (#33541)

Code Quality — Resolved 12 lint violations including functions exceeding parameter limits (refactored to options structs), context.Background() calls in functions already receiving ctx, and os.Exit() calls in library packages. (#33452)

📚 Documentation

Developer Specifications — Consolidated developer documentation with 7 tone fixes across 4 spec files, removing marketing language and subjective phrasing. (#33566)

Reference Updates — Added Gemini 3.5 Flash model configuration, documented footer-install template behavior, and specified JSON workflow field mapping for Copilot automation API imports. (#33522)

Glossary Expansion — Daily glossary scan added terms for tools.github.allowed-repos, repository access restrictions, and other workflow configuration options. (#33519)

🔧 Internal

MCP Refactoring — Extracted duplicated MCP wrapper logic into renderDefaultJSONMCPConfig helper, eliminating 10-12 line code blocks across four JSON engines. (#33482)

Chaos Testing — Updated Chaos PR Bundle Fuzzer to allow modifications to tests/chaos/** in safe-output PR creation. (#33553)

Workflow Cleanup — Removed centralized pull_request_reviewer dispatching from agentic_commands.yml, simplifying workflow routing. (#33542)
