feat: daily agentic workflow that runs rig to summarize files and post an issue

[Copilot]

Adds a daily agentic workflow that drives rig (Copilot SDK) to summarize TypeScript source files — first individually via a subagent, then globally — and posts the result as a GitHub issue.

Changes

• skills/rig/samples/140-file-summarizer.md — new rig sample with two chained agents:
  • summarizeFile (mini) reads one file via p.readInput("path") and returns a 1–2 sentence summary
  • projectSummarizer (small) discovers .ts files with p.bash(...), fans out to summarizeFile per file, then synthesizes a globalSummary

const summarizeFile = agent({
  name: "file-summarizer", model: "mini",
  input: { path: s.path },
  instructions: p`Summarize the following file in 1-2 sentences:\n${p.readInput("path")}`,
  output: FileSummary,
});

const projectSummarizer = agent({
  name: "project-summarizer", model: "small",
  agents: { summarizeFile },
  instructions: p`
List TypeScript source files (excluding node_modules and .git):
${p.bash("find . -name '*.ts' -not -path '*/node_modules/*' -not -path '*/.git/*' | sort | head -20")}
Call summarizeFile for each file path, then write a concise globalSummary of the whole project.
`,
  output: s.object({ files: s.array(FileSummary), globalSummary: s.string }),
});

• .github/workflows/daily-rig-file-summarizer.md — copilot agentic workflow (strict: true, schedule: daily) that:
  1. Runs npm install then node skills/rig/rig.ts skills/rig/samples/140-file-summarizer.md
  2. Emits a create-issue safe output with per-file summary table + global summary; closes the previous day's issue automatically via close-older-issues: true
• .github/workflows/daily-rig-file-summarizer.lock.yml — compiled lock file (generated by gh aw compile)

@copilot rig must use copilot-sdk

[Copilot]

@copilot rig must use copilot-sdk

Added configureAgent(copilotEngine()) to the sample — the import now includes configureAgent and copilotEngine from "rig" and explicitly wires the Copilot SDK engine. Commit: fix: explicitly configure copilotEngine in sample 140.

@copilot

• must configure copilot.copilot-sdk: true

[Copilot]

@copilot

• must configure copilot.copilot-sdk: true...

Added features:\n copilot-sdk: true to the workflow frontmatter and recompiled. The lock file now includes GH_AW_INFO_FEATURES: '{"copilot-sdk":true}'.

@copilot make it a single file - all in the markdown of the AW.

Review copilot-sdk frontmatter syntax

@copilot make it a single file - all in the markdown of the AW.

Review copilot-sdk frontmatter syntax

Done. The rig program is now embedded directly in .github/workflows/daily-rig-file-summarizer.md as a bash heredoc (cat > /tmp/gh-aw/agent/file-summarizer.ts << 'RIGEOF' ... RIGEOF), eliminating the separate skills/rig/samples/140-file-summarizer.md file.

Regarding frontmatter syntax: features:\n copilot-sdk: true is confirmed correct — it compiles to GH_AW_INFO_FEATURES: '{"copilot-sdk":true}' in the lock file. Lock regenerated with gh aw compile — 0 errors, 0 warnings.

Commit: refactor: consolidate rig program inline in AW markdown; remove separate sample

[pelikhan]

@copilot add a reference to the rig skill in the frontmatter and remove the details, just use a core region with the "rig" language to enable it

@copilot add a reference to the rig skill in the frontmatter and remove the details, just use a core region with the "rig" language to enable it

Done. The workflow now:

1. References the rig skill in the frontmatter: skills: - githubnext/rig/skills/rig/SKILL.md@<sha>
2. Replaces the verbose heredoc + run steps with a single rig code block containing the TypeScript program

The agent loads the rig SKILL.md as context, runs npm install, then executes the rig block directly. Lock recompiled — 0 errors, 0 warnings.

Commit: feat: add rig skill ref to frontmatter, replace heredoc with rig code block

[pelikhan]

@copilot not needed , instead say "Run this rig"

[Copilot]

Replaced the verbose instruction block and npm install bash step with "Run this rig". Lock file recompiled — 0 errors, 0 warnings.

@copilot copilot-sdk is a child field of engine

[Copilot]

Moved copilot-sdk: true to a child field of engine: — now engine:\n id: copilot\n copilot-sdk: true. Lock recompiled — 0 errors (1 expected experimental-feature warning).
