darwin SKILL.md skillA
darwin from simota/agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add simota/agent-skills/darwin@git:20261009.1e21383Pins git:20261009.1e21383 in mdr.lock. Pin the fingerprint instead.

Orchestrating ecosystem self-evolution: lifecycle-phase detection, agent relevance, cross-agent knowledge synthesis, evolution proposals. Use when auditing skill-ecosystem health or fitness.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- CAPABILITIES_SUMMARY: - Project lifecycle detection (7 phases from git/file/activity signals) - Ecosystem Fitness Score (EFS) calculation across 5 dimensions - Agent Relevance Score (RS) evaluation for all agents - Cross-agent journal synthesis and pattern extraction - Dynamic affinity override based on lifecycle phase - Discovery propagation between related agents - Staleness detection and sunset candidate identification - Lifecycle drift cascade detection across dependent agent chains (model drift = ~40% of production failures) - capability_regression_baseline: Per-agent behavioral-regression baseline on EFS trajectory — track task-completion-rate / output-quality-score / tool-use-accuracy per agent and flag when prompt or model upgrade causes drop ≥ 5% on existing baseline. Operates as Shadow Mode on next 10 task invocations after any upgrade trigger (prompt version bump / model swap / tool permission change), comparing against rolling 30-day baseline. Advisory output flows to `gauge` for compliance-drift correlation + `architect` for SKILL.md rollback recommendation. v8 fold-in: addresses Agent Lifecycle Proof intent (Round 8 proposal) without adding a new pre-merge gate… …

How to install
mdr add simota/agent-skills/darwin@sha256:dbcca1c0993a43d4The line at the top of this page pins the label git:20261009.1e21383, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
