synthesize-skill from agenttoolkit/altk-evolve is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add agenttoolkit/altk-evolve/synthesize-skill@git:20260708.f94af42Pins git:20260708.f94af42 in mdr.lock. Pin the fingerprint instead.

Convert a saved trajectory into a reusable agent skill (SKILL.md + supporting scripts) that future agents can invoke to skip rediscovered work. Use when a session captured a non-trivial workflow worth promoting from a free-text guideline to an executable skill.
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
# Skill Synthesizer ## Overview This skill reads a saved trajectory and produces a **reusable agent skill** — a `SKILL.md` plus any supporting scripts — that captures the *successful* workflow the session discovered. The output goes to `.evolve/skills/<skill-name>/` (canonical, evolve-managed) and to `.claude/skills/<skill-name>/` (so Claude Code's skills loader picks it up automatically). Future sessions on the same project can then invoke the skill directly instead of re-deriving the workflow. This is the **executable** counterpart to the `learn` skill's free-text guidelines: `learn` writes Markdown the next agent has to *read and decide what to do*; `synthesize-skill` writes a skill the next agent can simply *call*. ## When To Use Use this skill when a trajectory captured: - A **non-trivial workflow** that succeeded after trial-and-error (the eventual happy path is worth promoting from free-text advice to an invocable artifact). - A **reusable script or command sequence** the model wrote during the session — particularly one the agent had to reconstruct over multiple attempts. …

How to install
mdr add agenttoolkit/altk-evolve/synthesize-skill@sha256:3c7393a138cf5620The line at the top of this page pins the label git:20260708.f94af42, 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.
