| description | Resonance mapping — traces how ideas echo through a repo's timeline. Shows when a concept first appears in issues, returns in PRs, and lands in commits. Timestamp = SSOT. Finds signal by mapping pattern recurrence, not just frequency. |
/upstream-echo — Resonance Mapping
"ฟังก่อน แล้วสะท้อนกลับด้วยความหมาย"
An echo is not just reflection — it is the same signal returning with new meaning.
Usage
/upstream-echo <owner/repo>
/upstream-echo <owner/repo> --since 2026-05-25
Core Idea
Most digest tools count: how many commits? how many PRs?
upstream-echo asks: what echoes?
An idea that appears in an issue, then a PR title, then multiple commits = resonance.
A commit with no issue trail = noise, or an undisclosed decision.
A long-open issue with no PR echo = blocked signal.
Steps
1. Gather All Signals (timestamp = SSOT)
REPO="$1"
SINCE="${2:-$(date -v-14d +%Y-%m-%d)}"
gh api "repos/$REPO/commits?since=${SINCE}T00:00:00Z&per_page=100" --paginate
gh api "repos/$REPO/issues?since=${SINCE}T00:00:00Z&per_page=100&state=all" --paginate
gh api "repos/$REPO/pulls?state=all&per_page=100&sort=created&direction=desc" --paginate
2. Map Daily Activity (Pulse)
Group all events by day. Show commit + issue + PR on one bar — not three separate charts.
DATE commits prs issues ████ bar
────────── ─────── ─── ────── ─────────────────

2026-06-07 104 75 63 ████████████████
3. Find Echo Patterns (Resonance Chains)
Extract keywords from titles. Track where they appear:
- Issue opened with keyword → PR title has same keyword → commit message echoes it
ECHO: "wake"
issue #2597 "maw wake doesn't restore context" (2026-06-08)
PR #2606 "Let wake rehydrate only selected saved agents" (2026-06-09)
commit "Let wake rehydrate only selected saved agents" (2026-06-09)
This chain = intentional signal. Ideas that echo = things the team is thinking hard about.
4. Signal vs Noise Classification
SIGNAL = echoes ≥2 sources (issue+PR, PR+commit, issue+commit)
NOISE = bump/merge/ci commits with no issue trail
BLOCKED = issue with no PR echo (idea stuck at proposal)
ORPHAN = commit with no matching issue or PR (undisclosed decision)
5. Three-Line Verdict
PULSE: repo is [active/cooling/spiking]
RESONANCE: top 3 echoing ideas
WATCH: blocked/orphan signals that need attention
Rules
- Run real commands — no mock data
- Every claim backed by sha/issue#/PR#
- Echo = same concept in ≥2 event types (not just same word twice in commits)
- Show the chain, not just the count
- Timestamp is the only authority
