Skill Claude CodeCodex
Enforces the red-green-refactor TDD cycle. No production code without a failing test first. Use when implementing features, fixing bugs, or writing production code.
Skill Claude CodeCodex
Manages git worktree isolation for implementation chunks. Use when setting up isolated workspaces, creating worktrees for chunks, or merging completed chunk branches.
Skill Claude CodeCodex
Gates completion claims with mandatory evidence — no "should work" or "probably passes" without fresh verification output. Use when verifying test results, confirming builds pass, checking linter output, or validating acceptance criteria.
Skill Claude CodeCodex
Handles PDF operations (reading, creating, modifying). Use when extracting text from PDFs, converting markdown to PDF, merging or splitting PDFs, compressing, rotating pages, handling metadata, or when Claude Code's native PDF reading fails.
Plugin Claude Code
Thinking engine — Producer-Critic workflow with research, production, and review.
Agent
Use this agent for rigorous quality assessment of work produced by other agents, particularly producer-agent. Invoke after any significant artefact or deliverable is generated — and after each revision — to evaluate it against the task brief, applicable standards (such as writing-skills), and user requirements before…
Agent
Use this agent when you need to verify claims, sources, and assertions in research documents, reports, or any content where factual accuracy is critical. Operates in two modes: proactive verification (default) checks claims via web search and real-time source evaluation; retrospective verification checks documents…
Agent
Use this agent when quick, mechanical edits are needed across multiple files in the repository or /.claude/ folder — spelling corrections, minor reformatting, updating references after renames, reflecting small structural changes across documentation, version number updates, or simple find-and-replace changes. Handles…
Agent
Use this agent when you need to create, update, or edit artefacts — documents, guides, specifications, skills, or any content that should meet quality standards. Producer is the universal artefact creator; the orchestrator provides artefact-type-specific skills when relevant (e.g., writing-skills for Skills) and…
Agent
Use this agent when the user needs comprehensive research on a topic, question, or domain — gathering information, synthesising findings, and producing structured research output saved to versioned files in the work/ / directory. Supports two modes: quick (default, web-based research) and thorough (synthesis from…
Agent
Use this agent when the user needs to discover, collect, quality-assess, and store research sources with metadata for systematic research workflows. Performs Phase 1 of two-phase research — source discovery, multi-source retrieval, RADAR quality assessment, local storage with schema-conformant metadata, and a source…
Skill Claude CodeCodex
Conducts quality reviews of non-code artefacts. Use when reviewing or critiquing Skills, agents, workflows, documentation, or written materials, assessing quality against standards, or providing structured feedback.
Skill Claude CodeCodex
Sweep the project's LEARNINGS.md inbox and turn accumulated entries into durable skill, rule, or documentation changes. Run when ready to process learnings — not mid-task.
Skill Claude CodeCodex
Collects research sources with quality evaluation. Use when gathering or finding sources, building a source library, searching for academic papers, or performing RADAR assessment.
Skill Claude CodeCodex
Guides written communication — emails, reports, presentations, documents, website copy, newsletters, books. Use when writing or improving writing, adapting to an audience, or shaping document structure. Not for oral delivery or tool-specific formatting (slides, PDFs).
Skill Claude CodeCodex
Conducts research. Use when asked to research, investigate, explore, look into a topic, compare options, learn about an unfamiliar domain, or understand current state.
Skill Claude CodeCodex
Transforms unstructured requests into clear, actionable briefs. Use when writing a brief, preparing a specification, extracting requirements, or clarifying what a task needs.
Skill Claude CodeCodex
Invokes the critic-agent to review the latest produced output. Use when the user runs /critic to request a quality review of the most recent artefact or deliverable from the current workflow.
Skill Claude CodeCodex
Raises an artefact's signal-to-noise ratio by removing text that earns nothing for its reader — filler, repetition, over-explanation, ornamental phrasing — and relocating conditional detail to references. Use to slim a skill, agent, or document, cut bloat, tighten prose, or shrink a file that has grown too long. Tuned…
Skill Claude CodeCodex
Designs workflow structure. Use when planning a workflow, choosing which phases to include, or selecting a workflow pattern for a task.
Skill Claude CodeCodex
Re-explains concepts at a "knows the basics" level — strips jargon, uses analogies, and assumes broad general knowledge without domain expertise. Use when the user invokes /eli40 to request a simpler explanation of the previous message, or /eli40 to get an accessible explanation of a specific topic. Like ELI5 but…

Run /handover then commit and push changes to git.
Skill Claude CodeCodex
Session handover — end a session by systematically updating project state files for continuity. Use this when the session is ending, the user asks for a "handover", or when significant progress needs to be recorded.
