Codify
Scans a project's current practice, classifies each convention by how it is best enforced, and routes it to the fittest mechanism - config, project doc, rule, a project skill, or a paste-ready pointer. Use when setting up an existing project so the first agent execution follows its conventions, or when asked to establish, capture, or align project conventions.
Openspec Archive Change
Archive a completed change in the experimental workflow. Use when the user wants to finalize and archive a change after implementation is complete.
Openspec Sync Specs
Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.
Retro
Runs a post-task retrospective - detects user corrections, failures, and repeated mistakes, stages lessons as candidates, and proposes consent-gated improvements routed to their fittest destination (project rule, entry-file fact, memory, backlog, or skill update). Use when a task is complete or about to be marked done, before committing or closing out, or when the user says done, wrap up, or ship…
Harness Sync
Sets up and re-syncs a project's entry-file harness block — the wiring that brings retro in — plus cross-agent interop glue, with idempotent, diff-first, marker-managed writes; retro owns the learning loop. Use when setting up AI collaboration for a new or existing project, or when re-syncing the managed block after the skills were updated. Optional — projects bootstrap without it.
Skill Testing
Acceptance-tests any skill by running it through a fresh-context subagent with a minimal prompt, then verifying the output with mechanical checks only (grep, regex, counts, diff) so tester bias is isolated. Use when asked to test, verify, regression-check, or confirm a skill still behaves as its SKILL.md describes.
Skill Auditing
Audits any skills directory on two layers - format against shared authoring conventions, and content facts (commands, APIs, versions) against live documentation - reporting per-layer findings with sources. Use when asked to audit, review, or check whether skills are outdated, stale, or still correct.
Openspec Apply Change
Implement tasks from an OpenSpec change. Use when the user wants to start implementing, continue implementation, or work through tasks.
Skill Writing
Authors a new skill - for a skills collection, a project, or your personal setup - gathering requirements including where the skill lives, drafting SKILL.md with enforced conventions, collision-checking the name, and scaffolding an acceptance test plan. Use when the user wants to create, write, or add a skill, or when another skill (codify, retro) hands over a multi-step procedure to capture as a…
Rule Writing
Creates, edits, or removes a single project rule in the agent's native rule format, enforcing a non-discoverability admission filter and a hard rule budget with provenance stamping. Use when the user asks to add, change, or delete a project rule, or when another skill hands over a drafted rule.
Openspec Explore
Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
Openspec Propose
Propose a new change with all artifacts generated in one step. Use when the user wants to quickly describe what they want to build and get a complete proposal with design, specs, and tasks ready for implementation.
