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.
Update an OpenSpec change by revising its existing planning artifacts and keeping them coherent with one another. Use when the user wants to revise a change's plan, fold new decisions into it, or reconcile its artifacts after an edit. Never edits code.
Verify implementation matches change artifacts. Use when the user wants to validate that implementation is complete, correct, and coherent before archiving.
Use this skill when releasing OpenSpec: audit merged work and changeset coverage, decide whether a catch-up changeset PR is needed, prepare or resume the Changesets Version Packages PR, cut a beta or stable release, verify publishing, and polish GitHub release notes. Also use when asked whether an open release PR is complete, what the next release step is, or to continue a release paused for human approval.

Fact-checks OpenSpec user documentation with a fresh-context subagent that re-runs commands and checks claims against source. Manually triggered; not part of the drafting loop. Use when the user asks to verify, fact-check, or accuracy-check a docs page, section, or set of changed claims.

Guidance for Worktrunk (the `wt` CLI) — git worktree management, hooks, and config. Load when working out which worktree a `wt` command will act on, or reaching for the global `-C <path>` to target one; editing .config/wt.toml or ~/.config/worktrunk/config.toml; adding, modifying, or debugging hooks (post-merge, post-start, pre-commit, pre-merge, post-switch, etc.); configuring commit message generation or command aliases; or troubleshooting wt behavior. Also answers general worktrunk/wt questions.

Switches into OpenSpec docs-writing mode; loads the house style guide and drafts or revises pages in its voice (action-first, no preamble, scannable). Use when writing or editing pages in the OpenSpec docs tree.

Create a new worktrunk worktree (optionally in another repo) and switch this session's working directory into it. Use when launching a session that should work in its own worktree.

Triage a single issue on Codeberg (or any Forgejo/Gitea-compatible host). Use this skill whenever the user wants to assess, review, or triage a Codeberg issue — including when they paste a codeberg.org issue URL, say "look at issue 42 on owner/repo", "what should we do with this", "review this codeberg issue", or similar. Trigger even when the word "triage" isn't used: any request to read a Codeberg issue and recommend labels, a response, or what to do next falls under this skill. Reads the issue and its comments through the codeberg-mcp connector, then returns an assessment, proposed labels, a proposed English comment, and a two-part verdict (classification + action) for the user to apply manually.

Convention for building a reproducible demo artifact co-located with each implementation spec, so acceptance has something concrete to read. The author builds the demo against a running instance during the implementation PR; the reviewer reads it during acceptance without re-executing. Triggers on "build demo", "acceptance demo", "showboat", or any spec-linked PR that needs a proof-of-work artifact.

Fetch and display notifications from both GitHub and Codeberg in a unified markdown view with clickable links. Two modes: all (58+ notifications) or next-action (top 5 actionable items). Shows notifications sorted by newest first, grouped by platform. Use /unified-notifications for all notifications. Use next-action mode (python3 .claude/skills/unified-notifications/scripts/fetch_notifications.py next-action) to see only the top 5 items needing your attention. Triggers on requests like "check notifications", "show my notifications", "unified notifications", "next actions", "what needs attention", or "/unified-notifications".

Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.
CLAUDE.md or AGENTS.md?
CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.
What is a skill?
A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.
Can I search my own team's files too?
Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
