validate

A command that checks a TriadJS API description for consistency problems. It looks for issues such as duplicate endpoint names, duplicate routes, missing responses, and references to unknown models.

In plain words
What is it for?
Use it to check routes, endpoint names, response declarations, model references, and whether each bounded context uses only its own models.
Why use it?
It catches configuration and API-definition mistakes before they cause problems in generated clients or tests.

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

validate 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 — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Load the triad-cli skill for command reference, and triad-endpoint or triad-schema depending on what the validator surfaces.

Run triad validate --strict and act on the output.

Steps

  1. Run triad validate --strict. If $ARGUMENTS contains --coverage, include it as well.

  2. Parse the output. The validator checks:

    1. No duplicate endpoint names (operationId collisions in OpenAPI)
    2. No duplicate METHOD path combinations
    3. Every endpoint declares at least one response
    4. Every response body matches <ModelName> assertion references a model that exists in the router
    5. Endpoints inside a bounded context only use models declared in that context's models[]
  3. For each finding, propose a specific fix:

Duplicate endpoint name

Rename the newer endpoint to something unique. OpenAPI uses name as operationId, so collisions produce silent bugs in generated clients.

Duplicate METHOD path

Two endpoints claim the same route. Usually a copy-paste mistake. Merge them or change one path.

Missing response

Every endpoint needs at least one entry in responses. Even a 204 needs responses: { 204: { schema: t.empty(), description: '...' } }.

Unknown model in assertion

A behavior uses 'response body matches Pet' but Pet isn't registered on the router (not reachable from any endpoint's request or response). Either add the model to an endpoint's schemas or rewrite the assertion to a different model.

Bounded-context leak (warning → error in --strict)

An endpoint inside router.context('Pets', { models: [Pet, ...] }) uses a model that isn't in models[]. Either add it to the context's models[] (if it legitimately belongs) or move the endpoint to the right context.

  1. After fixing, re-run triad validate --strict to confirm all issues cleared.

Rules

  • --strict turns warnings into errors — bounded-context leaks fail the build. Use --strict in CI.
  • --coverage warns about endpoints missing boundary coverage (schema constraints with no test hitting them). Add ...scenario.auto() to the endpoint's behaviors to fix.
  • Validator findings are rarely "just rewrite the code" — usually they surface real modeling bugs. Take each one seriously before suppressing it.

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.

validate is a command published in the GitHub repository justhamade/triadjs (23 stars, last pushed 4mo ago), licensed MIT. It adds 33 tokens to every session and 553 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
