Agent Work Receipts Skill

Use this meta-workflow when a coding task needs reliable orientation, command evidence, and human-readable proof.

Recommended flow

1. Preflight the repo

npx repo-agent-brief . > AGENT_BRIEF.md
sed -n '1,220p' AGENT_BRIEF.md

For branch handoffs:

npx repo-agent-brief . --diff origin/main > AGENT_HANDOFF.md

2. Run important commands with logs

npx agent-runlog -- npm test
npx agent-runlog -- npm run lint
npx agent-runlog -- npm run build

Use runlogs for noisy debugging and CI reproduction.

3. Produce final receipts

npx @builtbyecho/trustlog run -- npm test
npx @builtbyecho/trustlog verify .trustlog/latest.json

Use Trust Log as concise final evidence for the user, PR, issue, or next agent.

4. If CI is missing, preview before modifying

npx @builtbyecho/add-ci . --tier 2 --dry-run

Only rerun without --dry-run after the user/project owner agrees with the plan.

Decision guide

• Need orientation? repo-agent-brief.
• Need full command logs? agent-runlog.
• Need final proof/receipt? trustlog.
• Need CI scaffold planning? add-ci --dry-run.

Safety rules

• Check git identity before commits/pushes.
• Do not run destructive commands without explicit approval.
• Keep .agent-runs/, .trustlog/, AGENT_BRIEF.md, and AGENT_HANDOFF.md local unless the user wants them committed or shared.
• Inspect generated artifacts before public posting; redaction helps but is not a guarantee.

Vaultline integration

When this workflow produces artifacts needed across sessions, upload key outputs to Vaultline at the end:

• AGENT_BRIEF.md or AGENT_HANDOFF.md
• .agent-runs/.../report.md
• .trustlog/latest.md

Example upload:

node -e '
const fs = require("node:fs");
const { Vaultline } = require("@builtbyecho/vaultline-sdk");
const filePath = ".trustlog/latest.md";
const content = fs.readFileSync(filePath, "utf8");
const vault = new Vaultline({ apiKey: process.env.VAULTLINE_API_KEY });
vault.files.upload({
  path: `agent-work-receipts/${Date.now()}-latest.md`,
  content,
  contentType: "text/markdown"
}).then(r => console.log("Vaultline fileId:", r.fileId));
'

This gives one durable artifact reference for PRs, tickets, and handoffs.
