endpoint-validator is agent-read markdown (skill) from notque/vexjoy-agent: Deterministic API endpoint validation with pass/fail reporting..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

# Endpoint Validator Skill
Deterministic HTTP endpoint validation: discover config, test each endpoint
against expectations, report pass/fail with CI-compatible exit codes.

| Signal | Reference | Content |
|--------|-----------|---------|
| Security header WARNs, HSTS/CSP/X-Frame | `references/security-headers.md` | Header checks, required values, remediation |
| Config errors, hardcoded IPs, timeouts | `references/endpoint-config-preferred-patterns.md` | Configuration failure modes and fixes |
| 401/403 failures, auth patterns | `references/auth-endpoint-patterns.md` | Bearer, API-key, cookie auth validation |
## Instructions
### Phase 1: DISCOVER
Read repository CLAUDE.md for base URL conventions or env var names.
Search for endpoint config in order: `endpoints.json` in project root,
`tests/endpoints.json`, inline specification from user. Prefer version-controlled
config over ad-hoc lists.
Config shape:
```json
{
"base_url": "http://localhost:8000",
"endpoints": [
{"path": "/health", "expect_status": 200},
{"path": "/api/v1/users", "expect_key": "data", "timeout": 10},
…Read the whole file at its exact version.
How to install
mdr add notque/vexjoy-agent/endpoint-validator@git:20260919.28d30f9mdr add notque/vexjoy-agent/endpoint-validator@sha256:b2a6f69eecc4b18bPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
