create-contract

create-contract is a command for Claude Code from rohitg00/awesome-claude-code-toolkit. It costs 0 tokens per session (285 once invoked), scanned A, original, Apache-2.0.

A command for creating a Pact contract test between a consumer service and a provider service. The contract records expected API requests and responses.

In plain words
What is it for?
Use it to define endpoints, request fields, response matchers, required provider states, and a shareable Pact contract file.
Why use it?
It helps teams agree on API behavior before services are connected and makes changes safer by covering successful and error responses.

Token cost

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.

Security

Grade A, and why

create-contract 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 4d 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.

What it actually says

/create-contract - Create API Contract

Create a Pact contract definition for consumer-driven contract testing.

Steps

  1. Ask the user for the consumer service name and provider service name
  2. Identify the API interactions to define (endpoints, methods, request/response schemas)
  3. Check if Pact is installed in the project; if not, suggest installation
  4. Create the contract test file with consumer and provider configuration
  5. Define each interaction: request method, path, headers, query params, and body
  6. Specify expected response status codes, headers, and body matchers
  7. Use Pact matchers (like, eachLike, term) for flexible matching instead of exact values
  8. Add provider states for each interaction describing required preconditions
  9. Generate the contract test and run it to produce the Pact file
  10. Validate the generated Pact JSON file is well-formed
  11. Save the Pact file to the pacts directory for sharing with the provider team

Rules

  • Use semantic versioning for consumer and provider names
  • Prefer Pact matchers over exact value matching for resilient contracts
  • Each interaction must have a unique description
  • Include both success and error response scenarios
  • Do not include authentication tokens in the contract; use provider states instead
  • Keep contracts focused on the data structure, not specific values
  • Name contract files as consumer-provider.json

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.
