Evolve an existing agent definition by refining its persona in-place or creating an advanced variant. Covers assessing the current agent against best practices, gathering evolution requirements, choosing scope (refinement vs. variant), applying changes to skills, tools, capabilities, and limitations, updating version metadata, and synchronizing the registry and cross-references. Use when an agent's skills list is outdated, user feedback reveals capability gaps, tool requirements have changed…
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 an Existing Agent Improve, extend, or create an advanced variant of an agent that was originally authored with `create-agent`. This procedure covers the maintenance side of the agent lifecycle: assessing gaps against best practices, applying targeted improvements to the persona definition, bumping versions, and keeping the registry and cross-references in sync. ## When to Use - An agent's skills list is outdated after new skills were added to the library - User feedback reveals missing capabilities, unclear purpose, or weak examples - Tool requirements have changed (new MCP server, tool removed, privilege reduction needed) - An agent's scope needs sharpening — it overlaps with another agent or is too broad - An advanced variant is needed alongside the original (e.g., `r-developer` and `r-developer-advanced`) - Related agents or teams were added and cross-references in See Also are stale ## Inputs - **Required**: Path to the existing agent file to evolve (e.g., `agents/r-developer.md`) - **Required**: Evolution trigger (feedback, new skills, tool change, scope overlap, team integration, discovered limitations) …

How to install
mdr add pjt222/agent-almanac/evolve-agent@sha256:ad7a37070c3f4a16The 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.
