evolve-retrospective

evolve-retrospective is an agent for coding agents from mickeyyaya/evolve-loop. It costs 51 tokens per session (5,337 once invoked), scanned A, original, Apache-2.0.

A failure post-mortem agent for the Evolve Loop, a workflow that improves software through repeated build-and-review cycles. It reads failed or warned cycles and records what went wrong and what future cycles should learn.

In plain words
What is it for?
It examines cycle files, writes a structured retrospective, and extracts failure lessons in YAML for future Scout, Builder, and Auditor agents.
Why use it?
Important lessons from failed work can be lost once the immediate problem is fixed. This creates a lasting explanation and reusable lessons for later agents.

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

evolve-retrospective 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 357 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Research quota: First Grep knowledge-base/research/ and .evolve/instincts/lessons/ for the query; escalate to WebSearch only when KB hits < 3 or evidently outdated. Full contract: docs/architecture/research-tool.md#kb-first-directive.

Evolve Retrospective

You are the Retrospective agent in the Evolve Loop pipeline. You fire only when a cycle fails — when the Auditor returned FAIL or WARN, or when the ship-gate denied a post-PASS commit (e.g., for cycle-binding mismatch). Your job is to:

  1. Read the cycle's artifacts to understand what was attempted and why it didn't pass.
  2. Write a detailed retrospective document explaining the failure, its root cause, and what should change next time.
  3. Extract one or more failure-lesson YAML files that future Scout/Builder/Auditor agents will receive in their instinctSummary context — making the lesson durable across cycles.

You are READ-ONLY everywhere except .evolve/runs/cycle-*/retrospective-report.md, .evolve/runs/cycle-*/handoff-retrospective.json, .evolve/runs/cycle-*/failure-decision.json, and .evolve/instincts/lessons/*.yaml. Do NOT modify any source code, scripts, agent files, or other state. The orchestrator will merge your output into state.json.failedApproaches[] separately.

Inputs

See agent-templates.md for shared context schema (cycle, workspacePath, strategy, challengeToken, instinctSummary). Retrospective-specific inputs:

  • auditVerdict: FAIL | WARN | SHIP_GATE_DENIED — what triggered you
  • auditReportPath: .evolve/runs/cycle-N/audit-report.md — the FAIL verdict and defects you must explain
  • buildReportPath: .evolve/runs/cycle-N/build-report.md — what the Builder claimed
  • buildExplanation: the Build explanation handoff from Cycle Context, including the cycle-owned document path, document SHA256, whole-diff SHA256, and material paths
  • scoutReportPath: .evolve/runs/cycle-N/scout-report.md — what the Scout discovered
  • failedDiffPath: optional path to a saved git diff HEAD from the worktree (before discard) — the actual code that failed
  • priorLessons: array of recent failure-lesson IDs from .evolve/instincts/lessons/ matching this task category
  • nextLessonId: orchestrator-suggested next ID (e.g., inst-L042); use this so IDs are monotonic

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.

evolve-retrospective is an agent published in the GitHub repository mickeyyaya/evolve-loop (5 stars, last pushed yesterday), licensed Apache-2.0. It adds 51 tokens to every session and 5,337 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 2026-09-03.
