runs-index

name	runs-index
description	Update index.json status. Use for: upsert index.json, update status/last_flow/updated_at. Deterministic writes - stable diffs, no creation. Use only in run-prep and *-cleanup agents. Invoke via bash .claude/scripts/demoswarm.sh index upsert-status. Use when this capability is needed.

Runs Index Skill

Deterministic updates to .runs/index.json. Write-bearing but with minimal surface.

Invocation

Always invoke via the shim:

bash .claude/scripts/demoswarm.sh index upsert-status [options]

Do not set PATH or call helpers directly. The shim handles resolution.

---

Operating Invariants

Repo root only

• Assume working directory is repo root.
• All paths are repo-root-relative.

Minimal ownership

This skill only updates:

• status
• last_flow
• updated_at

Other fields (canonical_key, issue_number, pr_number, etc.) are owned by run-prep, signal-run-prep, and gh-issue-manager.

Stable diffs

• Upsert by run_id (update in place, not append)
• Preserve existing ordering
• Output is sorted for stable git diffs

---

Allowed Users

Only these agents may use this skill:

• run-prep
• signal-run-prep
• signal-cleanup
• plan-cleanup
• build-cleanup
• gate-cleanup
• deploy-cleanup
• wisdom-cleanup

Command Reference

Command	Purpose
index upsert-status	Update run status in index.json

---

Quick Example

# Update index after signal cleanup
bash .claude/scripts/demoswarm.sh index upsert-status \
  --index ".runs/index.json" \
  --run-id "feat-auth" \
  --status "VERIFIED" \
  --last-flow "signal" \
  --updated-at "$(bash .claude/scripts/demoswarm.sh time now)"
# stdout: ok

---

Contract Rules

1. stdout: ok on success, error message on failure
2. exit code: 0 on success, non-zero on failure
3. Idempotent: Running twice with same args produces same result
4. No creation: If .runs/index.json doesn't exist, fail (run-prep owns creation)

Index Schema Reference

{
  "version": 1,
  "runs": [
    {
      "run_id": "feat-auth",
      "canonical_key": "gh-456",
      "task_key": "feat-auth",
      "task_title": "Add OAuth2 login",
      "issue_number": 456,
      "pr_number": null,
      "updated_at": "2025-12-11T22:15:00Z",
      "status": "VERIFIED",
      "last_flow": "signal"
    }
  ]
}

This skill only updates: status, last_flow, updated_at.

For Agent Authors

In cleanup agents:

1. Use runs-index for index updates (no inline jq)
2. Handle missing index — if .runs/index.json is missing, add a blocker and do not create it
3. Use runs-derive for reading — this skill is write-only

Example pattern in cleanup agent:

# Get current timestamp
TIMESTAMP=$(bash .claude/scripts/demoswarm.sh time now)

# Update index
bash .claude/scripts/demoswarm.sh index upsert-status \
  --index ".runs/index.json" \
  --run-id "$RUN_ID" \
  --status "$STATUS" \
  --last-flow "signal" \
  --updated-at "$TIMESTAMP"

---

Installation

The Rust implementation is preferred. Install to repo-local directory:

cargo install --path tools/demoswarm-runs-tools --root .demoswarm

The shim will automatically resolve in order:

1. .demoswarm/bin/demoswarm (repo-local install, preferred)
2. demoswarm on PATH (global install)
3. cargo run fallback (dev environments)
4. Python fallback (legacy)
