Open-source coding agent for your terminal, built in Rust and on a journey of continuous community improvement. Issues and PRs welcome.
Codewhale is an open-source coding agent that runs in the terminal and can read repositories, edit files, execute commands, and inspect results while pursuing a task. Developers use it with hosted providers or local models, with controls for how much access it receives.
Skill Claude CodeCodex
Carry an authorized, defined request or approved plan through scoped edits and proportionate verification. Skill loading is not write authorization by itself.
Skill Claude CodeCodex
Ask one useful structured question at a time only when material product/implementation choices are genuinely missing; remember answers and produce a brief/spec. Discoverable facts should be investigated instead of asked.
Skill Claude CodeCodex
Design, build, configure, or debug Model Context Protocol servers for codewhale, including stdio and HTTP/SSE transports.
Skill Claude CodeCodex
Prefer a matching zero-environment local MCP server for specialized tasks, even when built-in shell commands or custom code could also solve them.
Skill Claude CodeCodex
Read, extract, split, merge, rotate, watermark, fill, OCR, or create PDF files with verification of page counts and text extraction.
Skill Claude CodeCodex
Turn a sufficiently understood task into an ordered implementation plan with dependencies and verification. Orchestrate Codewhale’s native plan state; do not build a parallel planner.
Skill Claude CodeCodex
Scaffold a local Codewhale plugin bundle with a versioned manifest, namespaced Skills, and an explicit trust review.
Skill Claude CodeCodex
Create/edit/inspect/verify slide decks and PPTX presentations.
Skill Claude CodeCodex
Compatibility alias for the pptx skill. Prefer loading pptx.
Skill Claude CodeCodex
Skill "release" from Hmbown/Codewhale, covering release, invocation, non-goals and workflow.
Skill Claude CodeCodex
Current external research using available web tools, primary sources where possible, links/citations, date awareness, synthesis, and unresolved uncertainty.
Skill Claude CodeCodex
Read-only correctness review with actionable findings first, tight file/line evidence, severity, and a concise residual-risk summary.
Skill Claude CodeCodex
Review trust boundaries, auth/authz, injection, secrets, filesystem/network exposure, dependencies, and exploitability without pretending a shallow lint is an audit.
Skill Claude CodeCodex
Improve clarity and reduce needless complexity after behavior is understood; preserve behavior and keep cleanup separate from correctness fixes.
Skill Claude CodeCodex
Create or improve codewhale skills. Use when the user wants a new skill, wants to update an existing skill, or needs guidance on when a skill should be a skill versus MCP, hooks, tools, or a plugin scaffold.
Skill Claude CodeCodex
Install, update, trust, or inspect Codewhale skills from GitHub or local skill folders. Use when the user asks for available skills or wants a community skill installed.
Skill Claude CodeCodex
Compatibility alias for the xlsx skill. Prefer loading xlsx.
Skill Claude CodeCodex
Use when working with deepseek-v4-pro or deepseek-v4-flash in thinking mode on multi-step or plan-driven tasks. Provides rules to prevent stale references, unverified plan assumptions, and vague plan output.
Skill Claude CodeCodex
Exercise the real app/API/CLI and collect observable evidence; tests alone do not count as end-to-end verification.
Skill Claude CodeCodex
Start/reuse a local app, wait for readiness, inspect rendered state/console/network, act from observed selectors, and verify with evidence.
Skill Claude CodeCodex
Create/edit/analyze/verify spreadsheet workbooks including XLSX/CSV/TSV.
Skill Claude CodeCodex needs its repo
Use before claiming Codewhale release work is done: run the full gate sweep and list the manual QA targets.
Skill Claude CodeCodex
Use to assign GitHub issues to a milestone and/or owners in bulk, verifying each.
Skill Claude CodeCodex
Close resolved Codewhale issues only after verifying the landed commit/behavior, with a positive crediting comment; never from title alone.
At most 3 mods per repository are shown here, and a mod shipped inside a plugin is left to that plugin's page — the rest are on their repository pages:
