resonance-ops-retro

resonance-ops-retro is a skill for Claude Code, Codex from manusco/resonance. It costs 58 tokens per session (901 once invoked), scanned A, original, MIT.

A data-based review of a completed software cycle, such as a sprint, release, or recovered incident. It uses Git history, which records code changes, to explain what happened and what should improve.

In plain words
What is it for?
Use it after a completed cycle to produce a structured report with measures such as focus, complexity change, and the share of code devoted to tests.
Why use it?
It replaces a retrospective based mainly on memory or feelings with evidence about changes, authorship, code churn, and testing. It can reveal hidden effort and areas of drag.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

resonance-ops-retro scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/resonance-ops-retro: data-driven retrospectives

Role: the Analytics Officer. Invoked as: /retro (to analyze git history and generate a retro). Input: Timeframe (e.g., "last 7 days"). Output: A highly structured Retro Report in docs/retros/. Definition of Done: Retro report generated based on objective git data, including Focus Score, Complexity Delta, and Test Ratio. Narrative balances mathematical truths with human empathy.

Most retros are feeling-based. This protocol is data-based. Look at git history to discover what was actually accomplished, who drove it, and where the hidden drag was.

Prerequisites (fail fast)

  • Must be run inside a valid git repository.
  • Clean working tree.

Algorithm (Execution)

Copy this checklist and tick items as you go.

  1. Data Gathering (The Git Sweep): Run git log --since="X days ago" --oneline --stat. Group commits by author. Identify code churn vs adding new capability. Determine Test Ratio (Lines of tests vs Lines of application code).
  2. Metric Computation: Calculate the Retro Metrics using the exact definitions and git commands in Retro Metrics (compute them the same way every time, not by eye):
    • Shipping Streak: Consecutive calendar days with at least one commit.
    • Focus Score: Share of commits that stayed inside one top-level area vs commits that sprayed across three or more.
    • Complexity Delta: Net lines (insertions minus deletions), read against what actually shipped.
    • Test Ratio: Lines of test code changed vs application code changed.
  3. Narrative Assembly: Draft the retrospective document:
    • The Big Picture: 3-sentence summary of the week's theme.
    • Objective Metrics: Commits, LOC Changed, Active Days.
    • Highlights & Praise: Give credit where credit is due.
    • Growth Opportunities: Where did we stumble?
    • The Core Question: "Are we moving faster this week than last week?"
  4. Governance: Write retro_YYYY_MM_DD.md in docs/retros/. Ask the user what action items they want to extract from this retro into the planning queue.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

resonance-ops-retro is a skill published in the GitHub repository manusco/resonance (37 stars, last pushed yesterday), licensed MIT. It adds 58 tokens to every session and 901 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
