claude-skills is a large collection of reusable skills, commands, plugins, and supporting resources for coding agents across engineering, business, research, compliance, and productivity work. It is used by people who want agents such as Claude Code, Codex, Gemini CLI, or Cursor to follow specialized workflows. The catalogue contains selected skills and settings from the collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
What it costs to keep this loaded
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 | $0.00106 | $0.03292 |
| Opus 5.5 | $0.00042 | $0.01317 |
| Sonnet 5.5 | $0.00021 | $0.00658 |
| Haiku 4.5 | $0.00011 | $0.00329 |
Grade A, and why
contract-and-proposal-writer 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 2d 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 — 424 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Contract & Proposal Writer
Tier: POWERFUL
Category: Business Growth
Domain: Legal Documents, Business Development, Client Relations
Overview
Generate professional, jurisdiction-aware business documents: freelance contracts, project proposals, SOWs, NDAs, and MSAs. Outputs structured Markdown with docx conversion instructions. Covers US (Delaware), EU (GDPR), UK, and DACH (German law) jurisdictions.
Not a substitute for legal counsel. Use these templates as strong starting points; review with an attorney for high-value or complex engagements.
Core Capabilities
- Freelance development contracts (fixed-price & hourly)
- Project proposals with timeline/budget breakdown
- Statements of Work (SOW) with deliverables matrix
- NDAs (mutual & one-way)
- Master Service Agreements (MSA)
- Jurisdiction-specific clauses (US/EU/UK/DACH)
- GDPR Data Processing Addenda (EU/DACH)
Key Clauses Reference
| Clause | Options |
|---|---|
| Payment terms | Net-30, milestone-based, monthly retainer |
| IP ownership | Work-for-hire (US), assignment (EU/UK), license-back |
| Liability cap | 1x contract value (standard), 3x (high-risk) |
| Termination | For cause (14-day cure), convenience (30/60/90-day notice) |
| Confidentiality | 2-5 year term, perpetual for trade secrets |
| Warranty | "As-is" disclaimer, limited 30/90-day fix warranty |
| Dispute resolution | Arbitration (AAA/ICC), courts (jurisdiction-specific) |
When to Use
- Starting a new client engagement and need a contract fast
- Client asks for a proposal with pricing and timeline
- Partnership or vendor relationship requiring an MSA
- Protecting IP or confidential information with an NDA
- EU/DACH project requiring GDPR-compliant data clauses
Workflow
1. Gather Requirements
Ask the user:
1. Document type? (contract / proposal / SOW / NDA / MSA)
2. Jurisdiction? (US-Delaware / EU / UK / DACH)
3. Engagement type? (fixed-price / hourly / retainer)
4. Parties? (names, roles, business addresses)
5. Scope summary? (1-3 sentences)
6. Total value or hourly rate?
7. Start date / end date or duration?
8. Special requirements? (IP assignment, white-label, subcontractors)
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.

contract-and-proposal-writer is a skill published in the GitHub repository alirezarezvani/claude-skills (28,721 stars, last pushed 3d ago), licensed MIT. It adds 106 tokens to every session and 3,292 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-09-03.
