documentation-update-api

documentation-update-api is a cursor rule for Cursor from oakensoul/nextjs-cursor-prompts. It costs 0 tokens per session (2,353 once invoked), scanned A, original, MIT.

A guide for updating API documentation, which explains how software endpoints accept requests and return data. It keeps endpoint details, data formats, authentication, authorization, and OpenAPI specifications aligned with the implementation.

In plain words
What is it for?
Use it to inspect API routes and the data layer, verify authentication, update schemas and OpenAPI files, and check client examples.
Why use it?
It helps prevent developers from using incorrect routes, fields, login requirements, or integration examples.

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

documentation-update-api 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 2mo 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.

API Documentation Update Guide

This prompt systematically updates API documentation to reflect current endpoints, schemas, authentication methods, and integration patterns while maintaining comprehensive OpenAPI standards.

🎯 OBJECTIVES:

  1. UPDATE endpoint documentation to reflect current API implementation
  2. SYNCHRONIZE OpenAPI specifications with actual API behavior
  3. MAINTAIN authentication and authorization documentation accuracy
  4. ENSURE schema accuracy for all request and response types
  5. VALIDATE integration examples and client implementation guides

📋 API DOCUMENTATION UPDATE PROCESS:

STEP 1: API Implementation Assessment

Current API Analysis:
echo "🔌 API Implementation Assessment"
echo "==============================="

# Discover API routes
echo "Current API Routes:"
find src/app/api -name "route.ts" -o -name "*.ts" | sort

# Check API configuration
echo "API Configuration:"
find . -name "*api*" -name "*.config.*" 2>/dev/null

# Verify authentication setup
echo "Authentication Implementation:"
find src/ -name "*auth*" -o -name "*jwt*" -o -name "*token*" | head -10

# Check database/data layer
echo "Data Layer Implementation:"
find src/ -name "*schema*" -o -name "*model*" -o -name "*db*" | head -10

# Review middleware and validation
echo "API Middleware:"
find src/ -name "*middleware*" -o -name "*validation*" | head -5
API Change Detection:
  • New endpoints added since last documentation update
  • Modified endpoints with changed behavior or parameters
  • Deprecated endpoints that should be marked or removed
  • Authentication changes affecting API access patterns
  • Schema modifications affecting request/response structures
Documentation Gap Analysis:
  • Undocumented endpoints missing from API documentation
  • Outdated schemas not reflecting current data structures
  • Missing authentication docs for new auth methods
  • Incomplete examples lacking current implementation details
  • Broken integration guides that no longer work with current API

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.
