Agent skill
test-endpoints
This skill automates API endpoint testing and documentation. It runs curl requests against specified endpoints, captures responses, validates against OpenAPI spec, and generates markdown documentation. Use after implementing new endpoints or when verifying API behavior.

SKILL.md
- Single endpoint - Test one specific endpoint
- Multiple endpoints - Test a list of endpoints
- All endpoints for a resource - Test all endpoints under a path prefix
- Regression test - Re-test previously documented endpoints
Provide endpoint(s) or select an option.
Get from user:
- Base URL (default:
http://localhost:8080) - Endpoint path(s) to test
- HTTP method(s)
- Query parameters or request body
- Headers (e.g.,
Accept-Language: id) - Authentication if needed
Step 2: Execute Curl Requests
For each endpoint, execute curl with full options:
# GET with query params
curl -s -X GET "http://localhost:8080/api/v1/endpoint?param=value" \
-H "Accept: application/json" \
-H "Accept-Language: id" | jq '.'
# POST with JSON body
curl -s -X POST "http://localhost:8080/api/v1/endpoint" \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-d '{"key": "value"}' | jq '.'
# GET with path parameter
curl -s -X GET "http://localhost:8080/api/v1/resource/01HGXK3V6P8QWNM0T1234ABCDE" \
-H "Accept: application/json" | jq '.'
Step 3: Capture and Format Response
For each response, capture:
- HTTP status code
- Response headers
- Response body (formatted with jq)
- Response time
# Capture with timing and status
curl -s -w "\n\nStatus: %{http_code}\nTime: %{time_total}s\n" \
-X GET "http://localhost:8080/api/v1/endpoint" | jq '.'
Step 4: Validate Response Structure
Compare response against OpenAPI spec:
- All required fields present
- Field types match spec
- Enum values are valid
- Nested objects have correct structure
Step 5: Generate Documentation
Create markdown documentation in this format:
# API Endpoint Test Results
**Test Date:** YYYY-MM-DD HH:MM:SS
**Base URL:** http://localhost:8080
**Environment:** local/staging/production
---
## Endpoint: GET /api/v1/resource
### Request
```bash
curl -X GET "http://localhost:8080/api/v1/resource?page=1&limit=10" \
-H "Accept: application/json" \
-H "Accept-Language: id"
Response
Status: 200 OK Time: 0.045s
{
"data": [...],
"pagination": {
"page": 1,
"limit": 10,
"total": 100
}
}
Validation
- Status code matches expected (200)
- Response structure matches OpenAPI spec
- All required fields present
- Field types correct
</workflow>
<test_scenarios>
## Common Test Scenarios
### Pagination Testing
```bash
# First page
curl -s "http://localhost:8080/api/v1/resource?page=1&limit=10" | jq '.pagination'
# Last page
curl -s "http://localhost:8080/api/v1/resource?page=999&limit=10" | jq '.pagination'
# Invalid page
curl -s "http://localhost:8080/api/v1/resource?page=-1&limit=10" | jq '.'
Filter Testing
# Single filter
curl -s "http://localhost:8080/api/v1/search?subject_type=individual" | jq '.'
# Multiple filters
curl -s "http://localhost:8080/api/v1/search?subject_type=individual&nation=indonesia" | jq '.'
# Empty filter (should return all)
curl -s "http://localhost:8080/api/v1/search" | jq '.'
Sort Testing
# Sort ascending
curl -s "http://localhost:8080/api/v1/search?sort=name_asc" | jq '.data[:3]'
# Sort descending
curl -s "http://localhost:8080/api/v1/search?sort=name_desc" | jq '.data[:3]'
i18n Testing
# Indonesian
curl -s "http://localhost:8080/api/v1/resource" -H "Accept-Language: id" | jq '.data[0]'
# English
curl -s "http://localhost:8080/api/v1/resource" -H "Accept-Language: en" | jq '.data[0]'
Error Response Testing
# Invalid ID format
curl -s "http://localhost:8080/api/v1/resource/invalid-id" | jq '.'
# Not found
curl -s "http://localhost:8080/api/v1/resource/01HGXK3V6P8QWNM0T1234XXXXX" | jq '.'
# Invalid parameters
curl -s "http://localhost:8080/api/v1/search?year_range=invalid" | jq '.'
</test_scenarios>
<output_formats>
Output Format Options
1. Inline (default)
Show results directly in conversation.
2. Markdown File
Save to docs/api-tests/YYYY-MM-DD-{endpoint}.md
3. Summary Table
| Endpoint | Method | Status | Time | Valid |
|----------|--------|--------|------|-------|
| /api/v1/search | GET | 200 | 0.05s | Yes |
| /api/v1/filters | GET | 200 | 0.02s | Yes |

- Status codes verified
- Edge cases tested (empty results, invalid params)
- i18n variations tested (if applicable)
- Documentation generated </success_criteria>
Recommended Agent Skills
Expand your agent's capabilities with these related and highly-rated skills.
karpathy-mode
This skill should be used to enforce a disciplined coding workflow that avoids common LLM mistakes. It applies when writing code, implementing features, or when the user says /karpathy, /k-mode, or asks for "careful", "disciplined", or "minimal" implementation. Enforces assumption surfacing, simplicity-first coding, surgical changes, and test-driven execution.
disciplined-work
This skill should be used to execute work plans with strict coding discipline that avoids common LLM mistakes. It merges structured plan execution (phased workflow, incremental commits, quality checks) with disciplined coding guardrails (assumption surfacing, simplicity-first, surgical changes, test-driven execution). Triggers on /disciplined-work, /k-work, "disciplined work", or "careful work".
github-issues-from-spec
This skill transforms feature specifications, requirements documents, or plans into well-structured GitHub issues. It chunks large features into small, testable issues, creates them via gh CLI, and adds them to the appropriate GitHub project with labels. Use when converting specs to actionable issues.
new-go-endpoint
This skill automates the API-first workflow for creating new Go API endpoints. It handles OpenAPI spec updates, code generation, SQLC query creation, handler implementation, and Redis caching patterns. Use when adding new endpoints to the Lexicon backend.
obsidian-vault
Search, create, and manage notes in the Obsidian vault with wikilinks and index notes. Use when user wants to find, create, or organize notes in Obsidian.
edit-article
Edit and improve articles by restructuring sections, improving clarity, and tightening prose. Use when user wants to edit, revise, or improve an article draft.
