Evolve SKILL.md files from agent execution traces using a three-stage pipeline: trajectory collection from observed runs, parallel multi-agent patch proposal for error and success analysis, and conflict-free consolidation of overlapping edits via prevalence-weighting. Based on the Trace2Skill methodology.
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
# Evolve a Skill from Execution Traces Transform raw agent execution traces into a validated SKILL.md through a three-stage pipeline: trajectory collection, parallel multi-agent patch proposal, and conflict-free consolidation. This skill bridges the gap between observed agent behavior and documented procedures, turning successful runs into reproducible skills. ## When to Use - Execution traces reveal recurring patterns not captured in existing skills - Observed agent behavior outperforms the documented procedure - Building skills from scratch by recording expert demonstrations - Multiple agents propose conflicting improvements to the same skill ## Inputs - **Required**: `traces` -- set of agent execution logs or session transcripts (minimum 10 successful runs recommended) - **Required**: `target_skill` -- path to an existing SKILL.md to evolve, or `"new"` for skill extraction from scratch - **Optional**: `analyst_count` -- number of parallel analyst agents to spawn (default: 4) - **Optional**: `held_out_ratio` -- fraction of traces reserved for validation, not used in drafting (default: 0.2) ## Procedure ### Step 1: Collect Execution Traces …

How to install
mdr add pjt222/agent-almanac/evolve-skill-from-traces@sha256:0a9e6143d4efc105The line at the top of this page pins the label v1.0, 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.
