create-issue
Create GitHub issues from natural language, designed for ad hoc idea capture mid-flow. Invoke when user says "create an issue", "file a bug", "open an issue to track", "add a feature request", or "create a ticket".
create-pr
Create context-aware pull requests with issue integration. Invoke when user says "create a PR", "open pull request", "make a PR", "submit for review", or after completing work on a feature branch.
commit-changes
Create thoughtful git commits with conventional commits format. Invoke when user says "commit", "commit these changes", "create a commit", "save my changes", or after completing a task.
archive-work
Archive completed scratchpads and session logs to project history. Invoke when user says "archive this work", "clean up scratchpad", "archive scratchpad", or after PR is merged.
setup-work
Setup development environment from GitHub issue. Invoke when user says "init work on issue #X", "initialize issue #X", "setup issue #X", "prepare issue #X", "start fresh on issue #X", "start new work on issue #X", or provides a GitHub issue URL.
do-work
Execute development work from a scratchpad, tracking progress with TodoWrite and making atomic commits. This skill MUST be invoked as the first action when user says "start work on issue #X", "do work on issue #X", "work on issue #X", "continue work", "resume work", or "keep working". Do not fetch issue details or plan manually.
prime-session
Orient to current project by reading CLAUDE.md and architecture docs. Auto-invokes when Claude detects a new or unfamiliar repository. Can also be triggered by "orient me", "what is this project", or "prime session".
stash-artifact
Save ad hoc scripts, notes, or other artifacts to the project's context directory (outside the code repo). Invoke when user says "stash this", "save this script", "keep this outside the repo", "save to context", "stash artifact", or when user has a script or note they want preserved but not committed.
review-pr
Conduct comprehensive PR reviews with sprint/roadmap context awareness. Invoke when user says "review PR", "check this PR", "review pull request #X", or when asked to provide feedback on a PR.
interview-mode
Ensures proper requirements clarification before implementing features. Activates when asked to implement, build, create, or add features during what appears to be an interview or timed coding exercise.
android-architecture
Guides Android development with MVI state management, repository pattern, and clean architecture. Activates when implementing Android features, ViewModels, repositories, or data layers.
development-story-report

ragsharp-mcp-code-graph
|
ragsharp-build-code-graph
|
ragsharp-query-code-graph
|
gist-image
Use when you need to host images (screenshots, diagrams, PNGs) on GitHub for use in PR descriptions, issues, or markdown docs. Solves the problem that `gh gist create` rejects binary files.
gen-image
Analyze content and generate illustrations via Gemini image API
ammon
What time is it for Ammon? Looks up the current time in Denmark (Europe/Copenhagen timezone) and reports it.
gen-stt
Transcribe audio to text locally via NVIDIA Parakeet TDT 0.6B ONNX — single clip or batch parallel, no API key
explainers
Build an interactive explainer — a standalone web page that teaches one concept by letting the reader play with it. Use when the user says "build an explainer for X", "help me understand Y interactively", or "make a page that demonstrates Z". Ships a minimum HTML scaffold + methodology guide with pointers to reference implementations (dolt-explainer, larry-voice-samples, monitor-explainer, activation-energy-game, religion-evolution-explorer, how-long-since-ai). Prefers GitHub Pages + plain HTML by default; graduates to Vite + TypeScript + React only when interaction genuinely requires it.
herdr
Drive herdr (the terminal agent multiplexer) headlessly — create workspaces, start/prompt/wait-on coding agents in panes, read their output, and keep the claude/codex integrations healthy. Use when asked to create herdr workspaces or sessions, run or babysit another agent in a pane, check why an agent's status looks wrong, or install/repair herdr agent integrations.
docs
Use when answering questions about or writing code against a named third-party library/framework. Fetches fresh, authoritative documentation via Context7 (`ctx7`) instead of relying on stale training data. Fires both reactively ("how do I X with library Y") and proactively (about to write library code and unsure of current API). Skip for language stdlib and general CS concepts.
delegate-to-other-repo
Use when the user asks to make a change in a different git repo than the current session's cwd, and wants it done without polluting the current conversation with that repo's context. Typical triggers — "also fix X in the blog", "delegate this to the dotfiles repo", cross-repo tasks mentioned alongside current work.
cost-impact
Compute a Claude Code cost-impact report across a time window, grouped by repo with per-session detail. Prices per-turn per-model at published list rates (Fable 5 / Opus 5 & 4.x / Sonnet 4.x-5 / Haiku), includes subagent tokens, outputs markdown with clickable PR links and collapsible per-repo sections. Use when user asks "how much did I spend on Claude this week", "cost report", "/cost-impact", or wants a weekly retrospective on Claude usage.
clock
Schedule recurring tasks in your session. Defaults to time check every 15 min.
bulk
Bulk-parallel CLIs — turn N sequential gh/bd/git/file tool calls into a single fan-out JSON call. Use when the session is about to fire ≥3 similar sequential calls (gh pr view, bd show, Read of small files, up-to-date diagnose across repos).
build-bd-static
Build a static `bd` binary when Homebrew is unavailable or its dynamically-linked package is not portable enough for the machine.
background-usage
Check Claude Code plan usage in a throwaway background session — a herdr workspace under herdr, otherwise a hidden detached tmux session. Reports weekly usage percentage, time until reset, and pacing status.
architect-review
Run iterative architect review passes on a design spec, tracking convergence. Use when a spec is written and needs hardening before implementation — each pass finds fewer issues until the design stabilizes.
image-explore
Brainstorm multiple visual directions for a blog image, generate them in parallel, build a comparison page, and optionally publish as a shareable link (Surge.sh or gist).
image-read
Read (not generate) images via a subagent so the pixel payload stays out of the parent conversation. Dispatches Haiku by default, escalates to Sonnet/Opus when the caller flags ambiguity or needs load-bearing detail.
larry-voice
Speak text in Larry's voice via ElevenLabs → a Telegram voice note (opus/ogg). Use for any voice reply / ElevenLabs TTS. Charlie voice, eleven_flash_v2_5, IPv4-forced, optional blind-listen accent check.
learn-from-session
Extract durable lessons from a completed Claude session and codify them in the right CLAUDE.md files or skills. Use at the end of a long session, after a bug hunt that surfaced a non-obvious constraint, or when the user asks "what can we learn from this session". Discovers CLAUDE.md files dynamically, routes lessons by generic scope (project / shared conventions / environment / machine-local), enforces neutral voice, and asks for approval before editing.
