Prepare a claim-centered adversarial review packet for independent review. Use when a consequential, disputed, high-uncertainty, or large-scope design, recommendation, plan, assumption, implementation conclusion, or PR conclusion must be tested against evidence, scope, falsification criteria, and residual risk; not for ordinary patch defect review or security scanning.
Run and interpret Rust test coverage with cargo llvm-cov through a bundled script. Use for crate or workspace coverage summaries, uncovered lines/functions, diff-focused coverage review, targeted Rust test-gap recommendations, or cargo llvm-cov troubleshooting.
Maintain this chezmoi repo's portable package manifest. Use when adding, updating, removing, or verifying standalone GitHub release CLI packages in home/.chezmoidata/portable-pkgs.yaml.
Edit the shared agent contract — the chezmoi-managed AGENTS.md / CLAUDE.md instruction files generated from home/.chezmoitemplates/agents/ partials. Use when adding, changing, or removing a durable behavior rule for the agents, or when asked to update AGENTS.md, CLAUDE.md, the shared partials, or a tool's contract residue.
Drive a live marimo notebook as a workspace: run Python in the same kernel the user does, inspect live notebook state, and commit durable notebook changes. Use when the user wants to start a marimo notebook or pair on an active marimo session.
Capture or refresh persisted project conventions. Use when the user wants to initialize AGENTS.md, project style, validation commands, or tool preferences so agents stop rediscovering rules each session.
Create a GitHub pull request for the current branch. Use when the user wants to open a PR, optionally specifying a target branch (defaults to 'main'). The PR title and body should describe the branch's net change relative to the target branch, not the branch's internal history.
Create or revise an agent skill. Use when the user wants to add a new skill, improve an existing skill, define trigger conditions, design SKILL.md structure, or decide whether a skill should include scripts, references, or examples.
