fix: reduce Smoke Copilot context size to fix safe_outputs #539

Mossaka · 2026-02-05T23:17:49Z

Summary

Fix Smoke Copilot pipeline where safe_outputs job always skips because the Copilot agent never calls safeoutputs-add_comment.

Root Cause

PR #530 added explicit actions/checkout (full checkout) to all smoke workflow .md files. With full checkout, Copilot CLI's --add-dir "${GITHUB_WORKSPACE}" ingests the entire repo (~1M tokens). This overwhelms Copilot, causing it to use bash commands (gh pr comment) instead of MCP tools (safeoutputs-add_comment). The outputs.jsonl file is never created, and safe_outputs always skips.

Fix

smoke-copilot.md: Remove explicit steps: — compiler generates sparse checkout by default
postprocess-smoke-workflows.ts: Updated to:
- Convert sparse checkout → full checkout (needed for npm ci/npm run build)
- Add "Clean workspace for agent" step after build that removes src/, tests/, etc.
- Cleanup only applies to smoke-copilot.lock.yml

Result: full checkout → build awf locally → clean workspace → agent runs with ~200k tokens (not 1M)

Test plan

733 unit tests pass
Smoke Copilot agent invokes safeoutputs-add_comment
safe_outputs job runs (not skipped)
All other smoke tests still pass

Pull request overview

This PR fixes the Smoke Copilot workflow where the safe_outputs job was always skipping because Copilot CLI was overwhelmed by excessive context (~1M tokens from full repository). The fix involves a two-step approach: removing explicit checkout steps from the source .md file to let the compiler generate a sparse checkout, then using a postprocess script to convert the sparse checkout to full checkout (needed for building), and finally adding a cleanup step that removes source files after the build, reducing context to ~200k tokens.

Changes:

Remove explicit checkout steps from smoke-copilot.md to let compiler generate sparse checkout by default
Add logic to postprocess-smoke-workflows.ts to convert sparse checkout to full checkout and add workspace cleanup step
Update smoke-copilot.lock.yml with full checkout, local build steps, workspace cleanup, and version bumps (0.13.5→0.13.6, v0.0.99→v0.0.103)

The find | xargs rm command doesn't properly handle filenames with spaces or special characters. Consider using find ... -print0 | xargs -0 rm -rf or find ... -delete for robustness. While the current command should work for typical repository files, using null-delimited output is a safer best practice.

🎬 THE END — Smoke Claude MISSION: ACCOMPLISHED! The hero saves the day! ✨

Full repo checkout causes Copilot CLI to ingest 1M tokens of context (via --add-dir "${GITHUB_WORKSPACE}"), making it use bash commands instead of MCP tools. The safeoutputs-add_comment tool is never called, outputs.jsonl is never created, and the safe_outputs job always skips. Fix: Remove explicit actions/checkout from smoke-copilot.md (compiler generates sparse checkout by default). Update the postprocess script to: 1. Convert sparse checkout → full checkout (needed for npm ci/build) 2. Add a "Clean workspace for agent" step that removes src/, tests/, etc. after building, keeping only .github, .agents, dist, node_modules This reduces Copilot's context from ~1M to ~200k tokens, allowing it to properly use MCP safe-output tools.
