Add daily skill-optimizer workflow with artifact handoff and 3-improvement issue output

[Copilot]

This introduces a daily agentic workflow that runs fastxyz/skill-optimizer in a dedicated pre-agent job, then uses its artifact output to drive one actionable issue with exactly three improvement recommendations.

• Workflow topology (separate execution + handoff)

  • Added daily-skill-optimizer.md with a dedicated skill_optimizer job (needs: [activation]).
  • The job clones/builds fastxyz/skill-optimizer, runs initialization + benchmark/dry-run flow, and writes structured results (summary.json) plus logs.
  • Results are uploaded as a named artifact and downloaded in the agent phase for analysis.

• Agent behavior (issue creation contract)

  • Configured safe-outputs.create-issue with a single-issue cap.
  • Prompt now requires:
    • exactly one created issue,
    • exactly three numbered improvements,
    • evidence tied to artifact files,
    • run mode/status from summary.json.

• Compiled workflow output

  • Added the generated lock file (daily-skill-optimizer.lock.yml) aligned to the new markdown workflow definition.

Pull request overview

Adds a new daily Agentic Workflows pipeline that runs fastxyz/skill-optimizer in a dedicated pre-agent job, hands results to the agent via an artifact, and has the agent create a single issue containing exactly three improvement recommendations.

Changes:

• Introduces a new daily-skill-optimizer.md workflow with a skill_optimizer job that clones/builds/runs fastxyz/skill-optimizer and uploads logs + summary.json as an artifact.
• Configures the agent phase to download the artifact and enforce a “one issue / exactly three improvements / evidence from artifacts” contract via Safe Outputs.
• Adds the compiled workflow output (daily-skill-optimizer.lock.yml) aligned to the markdown workflow definition.

OPENROUTER_API_KEY is set at the step level, so it will also be visible to npm ci/npm run build and other third-party code executed in this step (including npm lifecycle scripts). To reduce secret exposure, consider scoping this secret to only the benchmark invocation (e.g., export it immediately before the non---dry-run run, or move the benchmark run into a separate step with env:).

[Copilot]

The agent phase requires summary.json, but with set -euo pipefail a failure in git clone/npm ci/npm run build will exit the step before summary.json is written. Consider ensuring summary.json is always produced (e.g., via a trap/finally block that writes a failure summary including which phase failed), and capture exit codes for clone/build similarly to init/run.

[Copilot]

The artifact upload path points at /tmp/gh-aw/skill-optimizer-results, which also contains the cloned skill-optimizer-src checkout (and its node_modules after npm ci). This can greatly inflate artifact size and slow/fail uploads. Consider keeping the tool checkout outside the artifact directory or deleting skill-optimizer-src before uploading, and/or uploading only the specific result files needed by the agent (e.g., summary.json + logs).
