Open Cowork is an open-source desktop application for Windows and macOS that helps users install and use Claude Code, MCP tools, and Skills. It is intended for people who want a graphical way to work with coding agents, multiple models, sandboxed environments, and Feishu or Slack integrations. The catalogue skills extend its agent-oriented workflow.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.02418 |
| Opus 5.5 | $0.00000 | $0.00967 |
| Sonnet 5.5 | $0.00000 | $0.00484 |
| Haiku 4.5 | $0.00000 | $0.00242 |
Grade A, and why
codex-pr-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Repo rules:
- Conventional Commits (feat/fix/refactor/perf/docs/test/build/chore/ci/style/revert)
- TypeScript strict mode, ESLint + Prettier (2-space indent)
- React functional components with hooks
- Tailwind CSS (no CSS modules),

PR Context (required)
Before any analysis, load PR metadata, latest head SHA, and diff from the GitHub Actions event payload.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

codex-pr-review is a command published in the GitHub repository OpenCoworkAI/open-cowork (2,232 stars, last pushed 7d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,418 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-14.
Other commands, from other repositories
audit-agents-skills
Audit quality of agents, skills, and commands in a Claude Code project.
deslop
Audit a standing codebase for accumulated slop — comment noise, AI-tell doc prose, speculative abstraction, reinvented stdlib, duplicate helpers, dead code, swallowed errors, convention drift. Fans out read-only auditors sharded by wiki domain and writes an indexed report into a scratchpad for you to read. /deslop…
assemble-team
Assemble a pre-built agent team for parallel work - review, feature, debug, cross-platform, full-stack, or research.
review-code
Trigger a comprehensive code review on recent changes or specified files.
review-branch
Review the current branch's diff against base by dispatching atomic-reviewer. No orchestration loop, no spec required — pre-flight before /commit pr or /commit merge.
implement
Implement in the main agent, with atomic-reviewer gating every checkpoint. For work whose context is already in this conversation, where a fresh subagent would have to re-read what you have already read. Same checkpoints, commit-per-green, and finalize as /subagent-implementation; you write the code.
