Discovery before changes: explore the local codebase, run multi-source external research, and reconstruct why a past decision was made from evidence outside the code. Each dispatches a subagent by default so the reading stays out of the main thread, with source tiers, falsification, recency gates and a coverage ledger, and persists EXPLORE.md / RESEARCH.md / INTENT.md handoff artifacts. A research sweep workflow (/discovery:research-sweep) backs deep research with adversarial claim verification.

Read-only code measures for a change, with cited references and no verdict: lines per file (audit size), cyclomatic, cognitive, and Halstead complexity (audit complexity), duplication (audit-duplication), per-function coverage and CRAP from existing lcov, Cobertura, coverage.py, or Go artifacts (audit-coverage), TypeScript and Python type debt (audit type-debt), metric literacy (principles), and setup. Uses only collectors already installed; never installs or runs tests.

Disciplined implementation stage: execute approved plans inline (`/implementation:implement`) or via orchestrated worker subagents (`/implementation:implement-dispatch`) with incremental validation, TDD-by-default cadence, green-checkpoint commits, scope-fence drift detection, and divergence detection that routes back to planning. Build/test/lint, testing, and outcome verification live in the companion `toolchain`, `testing`, and `verification` plugins, invoked when installed.

Routes agent instructions to the surface that loads them at the right time. audit finds conventions narrower than the always-loaded CLAUDE.md or AGENTS.md, or stranded in docs Claude never loads, and proposes a destination with a validated paths glob; safety content is never demoted. realign applies each move and regenerates an index. check verifies globs and index. migrate moves content to AGENTS.md with a CLAUDE.md shim. setup registers a git pre-commit entry that fails on a stale rules index.

Creates pixel art with no external tools: sprites (sprite), animation sprite sheets for RPG Maker MZ, Godot, PICO-8, or plain strips with Aseprite-style frame data and GIF previews (animate), tilesets and parallax (tileset), UI skins and bitmap fonts (ui), effect sheets (vfx), and animated scenes as one HTML file (scene). Specs are palette-locked; a humanoid kit and a Python stdlib renderer write PNG, GIF, and frame data with a render-review loop. Optional Aseprite adapter.

Front door for interface design: terminal and CLI output, TUIs, prompt themes, Claude Code mods, web and app UI. design detects the project's own design system and the design tools installed, routes each concern to the best present source with the project first, and supplies its own guidance where nothing covers the concern. audit reviews interface code read-only by concern lane; glossary is a reverse term lookup. Terminal guidance is its own contribution.

Context-aware disk hygiene for arbitrary directory trees: inventories orphaned and temporary artifacts, classifies evidence into review tiers, and offers exact-path cleanup only after a fresh safety preview and explicit per-tier approval. The target is read-only by default; OS-managed paths, links and mount points, VCS-tracked content without the complete checkout evidence bundle, changed entries, and live-handle uncertainty fail closed.

Post-use behavioral audit (plugin-quality:audit) of any Claude Code plugin skill, agent, hook, command, or config you have used. Six steps: capture evidence; map behavior in a fresh subagent that records errors, improvements, and quality-of-life items against standards; a blindspot pass; an interactive contract lock; review with a research gate on each finding's claims and fixes; and a confirmed work item for the maintainers. Uses context-usage snapshots when present.

Measures a Claude Code session's fixed startup context payload per item at a pinned binary version, including per-tool attribution of the built-in tool pools that /context reports only as totals, derived by A/B deny differencing. Falls back from an SDK meter to a headless /context parser, then to an error rather than a wrong number. Keeps a before/after ledger per lever. Shows a live context breakdown in a pane or above the prompt. Report-only by default; fix applies one approved project trim.

GitHub admin-plane audit, advice, and guided setup over the authenticated user's own gh CLI: billing and cost control, security posture, rulesets and settings drift, Actions policy, and every other org/repo/enterprise settings area. Grounded in live state and current official GitHub docs (zero vendored knowledge); read-only by default, every mutation user-in-loop.
3 skills
Find and make improvements to anything, from one method to a whole feature. find ranks evidence-cited candidates by value-to-effort and hands the pick to planning; improve ships one improvement, measured against the repo's standards and, when the focus asks for it, current upstream guidance, as one small draft PR. Both run unattended on a schedule.
3 skills
Measures whether a test suite detects faults, not merely runs code. /mutation-testing:principles answers operator, mutant-state, and metric questions from the literature. /mutation-testing:setup verifies the mutation tool and writes tracked config. /mutation-testing:audit runs mutation analysis on the diff (or, with --exercised, on code the changed tests call), reports surviving mutants and why each lived, verifies source was restored, and can save survivors as findings.
3 skills
Builds throwaway code to answer a design question before committing to architecture: a logic facet (an interactive terminal app over a portable state model), a UI facet (radically different visual variants on one route), and a user-invoked generator facet (a throwaway tool the person tunes, whose saved output goes into the project).

Text-to-speech narration. The narrate skill turns a script into narration.wav plus words.json, with a start and end time per word. The default backend runs Kokoro-82M locally. The optional elevenlabs backend sends the text to the third-party ElevenLabs API (ELEVENLABS_API_KEY or vault-exec) after showing the character count against your quota, caching repeats; an organization can forbid it. You install espeak-ng (GPL-3.0); a hook installs Python packages, setup the models, check.py reports gaps.

Shapes assistant output for a reader with ADHD: action-first and low-friction. adhd:shape is a standing session posture: lead with the next action, number steps, restate state across turns, cap and rank lists, size work concretely, cut preamble. adhd:clarify reshapes one dense, decision-heavy message: one decision at a time, jargon defined, operative terms quoted verbatim, with an HTML decision table for big content. Reauthored in part from ayghri/i-have-adhd (MIT).

Build source-backed AI-industry briefings from official vendor publications, configured RSS/Atom feeds, GitHub releases, reputable secondary reporting, and user-supplied URLs. Deduplicate, rank, and present results as markdown or optional HTML/PPTX decks, with repository-owned profile, audience, and brand configuration. Automated X/Twitter collection is disabled; Playwright is used only for deterministic local rendering.

Detects and removes AI-writing tells (slop) in tracked markdown, commit messages, PR bodies and interface copy: em dashes, emoji formatting, AI vocabulary, negative parallelisms, chatbot phrases, filler, hedging, citation artifacts and model-era phrases, from a catalog based on Wikipedia's Signs of AI writing plus a graded model-vocabulary inventory. Read-only audit by default (deterministic detector plus judgment rubric); an explicit fix action rewrites findings behind a semantic-diff guard.
2 skills
Finds prose in tracked markdown that restates content an external source owns (vendor docs, blogs, articles) without attribution, confirms the source, and converts the copy into a pointer, a citation, or a dated stamped record. Documentation attribution, not software supply chain. Scripts do only mechanical work; judgment is LLM work. Read-only audit by default; explicit fix and sweep actions apply changes behind a semantic-diff guard and live pointer checks.

Contracts for governed autonomous agent operation: role topology, binding seam, telemetry, return accounting, trigger dispatch, a per-work-class guardrail matrix, a standing-routine catalog, and a runner charter. A guided setup skill writes an org's binding, wires OTLP telemetry (file default), human-attested return capture, and signal adapters behind one governed dispatch entrypoint, binds the guardrail matrix to isolation substrates after a live probe, and schedules routines.

Per-session context-window observability. A mod writes each session's context-window figures to a snapshot file and shows the person a toast and a transcript line when the context zone (light, moderate or heavy, from bands in zones.json) worsens; with model_notices on (off by default) it also tells Claude the zone at each crossing, approach and compaction. /context-usage prints status and toggles an optional band row. It answers a status tool. A PostCompact hook leaves a marker.

Short explainer videos made with ManimCE, narrated when the speech plugin is installed and silent otherwise. The produce skill plans the beats, writes one scene script whose scene changes follow the narration's word timings, renders at low quality first, muxes narration and captions with ffmpeg, and checks every render with ffprobe and a frame read-back. A SessionStart hook installs the hash-locked Python packages; scripts/pydeps.py check reports readiness.

Miro board management over the Model Context Protocol: create and manage boards, sticky notes, shapes, frames, connectors, and tags for EventStorming, brainstorming, and diagramming. Ships a local stdio MCP server that installs its pinned npm dependencies on first launch (needs Node.js 24+ and npm); installs disabled, so opt in. The server starts without a Miro API token; until one is set, each tool call explains how to set it.

Turns a recurring correction into an enforced check. /corrections:codify counts how often a described mistake recurs, picks the strongest enforcement-ladder rung that can catch it, and proposes a check proven to fail on the old code and pass on the current code, using scripts/prove-check.sh to run it in temporary worktrees at two refs. It also takes a review findings file (codify findings <file>), PR review comments (codify reviews) or preferences typed across sessions (codify preferences).

Iteratively reduces coupling in documents, code modules, applications, or repositories: scans for change-transmitting dependencies against a coupling model (strength ladder, connascence, volatility), verifies each finding, applies a budgeted batch of safe behavior-preserving reductions, and keeps a ledger so structural candidates route to design and later runs resume. When a value changes, it finds and classifies every site stating it and converts setup sites to references.

Domain-driven-design practice skills. Today it owns a consuming project's ubiquitous-language glossary: finds and reads it for other skills, seeds a first one from the code with a person accepting each term, resolves ambiguous or overloaded terms, records canonical language and rejected synonyms, and checks code, copy and error messages for rejected words, within already-known bounded contexts.

Agent-to-agent reach across a personal fleet (fleet:reach): from any Claude Code lane (WSL or native Windows, any machine), run a script, prompt, or query and wait, message a session, or start a named session in another lane. Each lane signs into its own Claude account, so built-in peer tools see only their own lane. Carries the route matrix for headless turns in the target lane, target resolution from the fleet manifest, and a posture that keeps agent launches prompting.

Generates and evaluates fresh name candidates for an identifier, file, module, skill, repo, or domain term (naming:name-it-better). It distills a context brief, runs blind fresh-context generators from distinct lenses (responsibility-literal, moment-of-use, domain-lore), and scores a shortlist against the org's naming criteria. The human always picks; it never locks a name. An optional tournament mode adds elimination rounds with independent judges for high-stakes names.

One-step access to Anthropic's first-party playground plugin: declares the cross-marketplace dependency, routes playground-shaped requests to the upstream skill when it is installed, emits the install commands when it is not, and carries field-tested prompt recipes, cloud-session delivery guidance, and consumer cautions. Generates nothing itself.

Eval-only: declares the pinned Playwright MCP server the browser-mcp-probe case drives (start.sh)
1 MCP server
SQL Server and Azure SQL Database access for agents, read-only by default under a read-only database principal, with an opt-in write tier a person approves per call (ADR 0086). Ships the versioned config schema and loader, read and write reject lists, a stdio MCP server with fixed query, list_objects, describe_object, preview_write and write tools, a tedious executor with per-call transaction guards and a row-count-checked write batch, and a setup skill.

A TDD knowledge base distilled from cover-to-cover readings of Kent Beck's Test-Driven Development: By Example and Vladimir Khorikov's Unit Testing: Principles, Practices, and Patterns. Fourteen author-attributed reference files behind a routing table, plus a no-load quick decision guide, answer the WHY behind test design decisions.

Prose a scanning reader can use. /writing:be-concise puts the bottom line first, cuts words the meaning does not need, and keeps structure scannable and tone factual. Bare, it sets a standing posture; given a target, it reshapes it and reports word counts. For tickets, PR descriptions, changelogs, READMEs, and status updates. Never drops a decision, number, ask, error, or warning. Paraphrases NN/g, GOV.UK, US plain-language guidelines, Google and Microsoft style guides, and BLUF.

Read X (formerly Twitter) posts, note tweets, and X Articles as Markdown without an X API key, via a documented fallback ladder over third-party converters: xtomd.com for single posts and articles, Thread Reader App for unrolled reply chains, plus a dated list of other services for replies and media. A pasted X link becomes readable content instead of a login wall.

Installs the vital lifecycle plugins in one step, from planning through the pull request and session handoff, plus the guardrails safety hooks: a bundle with no skills, agents or hooks of its own, whose dependencies are planning, discovery, verification, toolchain, review, source-control, session-flow, work-items and guardrails.
A mod that masks email addresses and secret-shaped text in what Claude Code draws, for recordings and screen shares. It changes the screen only; the transcript, the model's context and the files on disk are untouched, so it is not a privacy or data control.
