contract-reviewWhen the user needs to review an existing contract, assess risk in proposed terms, or evaluate a contract before signing.
Contract Review is an agent skill from shawnpang/startup-founder-skills. When the user needs to review an existing contract, assess risk in proposed terms, or evaluate a contract before signing.
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Legal & Compliance, covering Contract review. The repository describes itself as: AI agent skills for tech startup founders — fundraising, sales, product, recruiting, engineering, legal, ops, and growth. Works with Claude Code, Cursor, Codex, and any Agent… The licence is MIT.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 4ad31b4. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Contract Review loads about 2.2k tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 1,156 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/contract-review/SKILL.md (or your agent's skills folder).Activate when a founder has received a contract to sign and wants to understand the risks before proceeding. This includes vendor agreements, customer enterprise agreements, partnership deals, investment documents, employment agreements, NDAs, IP assignment agreements, and any other binding legal document. Also activate when the user says things like "review this contract," "is this agreement fair," "what should I push back on," or "flag anything concerning."
| Section | Summary | Flag | Risk | Recommended Action |
|---|---|---|---|---|
| Liability Cap | Capped at fees paid in prior 6 months | Yellow | Low cap for potential damages | Negotiate to 12-month cap |
| IP Assignment | Broad assignment of all work product | Red | Could capture pre-existing IP | Add carve-out for pre-existing IP |
Bulleted list of protections that should be present but are not.
Numbered list of what to do, in order of importance.
Red Flags — Immediate concern, do not sign without modification:
Yellow Flags — Worth negotiating, but not necessarily deal-breakers:
Green Flags — Standard and reasonable:
terms-of-service — When reviewing a customer's redlines to your terms of service, use contract-review to assess their proposed modifications.privacy-policy — Data processing addendums and DPAs often accompany contracts. Review these for consistency with your privacy commitments.User: "We're about to sign a contract with a data enrichment vendor. Here are the terms. Can you flag anything concerning?"
Good output excerpt:
Overall Risk Level: Yellow
The agreement is mostly standard but has three issues worth negotiating before signing.
Section Flag Issue 4.2 Data Rights Red Vendor claims a "perpetual, irrevocable license to use Customer Data for product improvement and benchmarking." This means they keep and use your data forever, even after termination. Negotiate to: license limited to providing the service, terminates on contract end, anonymization required for any aggregate use. 7.1 Liability Yellow Cap is set at "fees paid in the prior 3 months." For a $2K/month contract, that is a $6K cap. If they cause a data breach affecting your customers, your exposure could be much higher. Negotiate to: 12 months of fees, with a carve-out for uncapped liability on data breaches and IP infringement. 9.3 Termination Yellow 90-day notice required to cancel, even on annual renewal. Combined with auto-renewal, this means you need to decide 3 months before your renewal date. Negotiate to: 30-day notice, or set a calendar reminder now. Missing Protections:
- No data deletion timeline after termination
- No breach notification obligation
- No sub-processor list or approval rights
- No SLA or uptime commitment
User: "A new engineer's offer letter has an IP assignment clause. They're concerned about their open-source side projects. Can you review?"
Good output excerpt:
Section 8 — Invention Assignment: Red Flag
The current language reads: "Employee assigns to the Company all right, title, and interest in any invention, improvement, or work of authorship created during the term of employment."
This is overly broad. It captures the engineer's weekend open-source contributions, personal projects, and anything they create during employment regardless of whether it relates to company business.
Recommended revision: Add a carve-out: "...created during the term of employment that (a) relates to the Company's current or reasonably anticipated business, (b) was developed using Company resources, or (c) resulted from work performed for the Company."
Also add a Schedule A listing the engineer's pre-existing IP and active side projects, explicitly excluded from assignment. Note: California Labor Code Section 2870 already provides some protection, but an explicit carve-out is clearer and avoids disputes.
Disclaimer: This skill provides contract analysis for educational and planning purposes only. It does not constitute legal advice. Contract interpretation depends on jurisdiction-specific law, the full context of the business relationship, and facts that may not be apparent from the document alone. Always have a qualified attorney review contracts before signing, especially those involving significant financial commitments, IP rights, or liability exposure.

Run `npx skills add shawnpang/startup-founder-skills --skill contract-review -a claude-code`. Or copy the skill folder (skills/contract-review in shawnpang/startup-founder-skills) into .claude/skills/contract-review in your project. Claude Code loads it when a task matches its description.
Run `npx skills add shawnpang/startup-founder-skills --skill contract-review -a codex`. Or copy the skill folder (skills/contract-review in shawnpang/startup-founder-skills) into .agents/skills/contract-review in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add shawnpang/startup-founder-skills --skill contract-review -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/contract-review, .gemini/skills/contract-review, .github/skills/contract-review and .opencode/skills/contract-review in your project.
SKILL.md names no scripts, command-line tools or credentials: Contract Review is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Contract Review is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.2k tokens (SKILL.md is roughly 8.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
