strict-validation-setup

strict-validation-setup is a skill for Claude Code, Codex from OutlineDriven/odin-claude-plugin. It costs 61 tokens per session (2,401 once invoked), scanned A, original, Apache-2.0.

A setup procedure for strict validation loops, including task goals, configuration, and failing tests.

In plain words
What is it for?
Use it to bootstrap strict-mode tooling, create a task-specific GOALS.md file, connect it through AGENTS.md, and add failing tests from an observable goal.
Why use it?
It gives an agent an explicit pass-or-fail target and the scaffolding needed to check its own work.

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

strict-validation-setup 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 yesterday.

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.

Strict validation setup

Contract

Field Bound contract
Trigger User invokes a strict-mode validation or verifiable-goals loop setup.
Authority Reversible local write: idempotent tooling-config merge, per-task GOALS.md scaffold, and failing-test authoring; no remote, credential, or deployed mutation.
Side effect Merges strict-mode tooling configs idempotently, ensures AGENTS.md points to per-task GOALS.md, scaffolds .agent-tasks/<id>/GOALS.md, and writes failing tests; one-shot bootstrap.
Done Strict configs are merged idempotently and per-task GOALS.md plus failing tests are in place, with task goals kept out of AGENTS.md.

Inputs

  • User goal (required): enough observable behavior to derive at least one pass/fail success criterion. If not observable, stop before writing and ask for the missing outcome.
  • Task ID (optional): must match ^[a-z0-9][a-z0-9-]{0,63}$. If absent, use task- followed by the first 12 lowercase hexadecimal characters of SHA-256 over the exact UTF-8 user-goal text.
  • Overwrite authorization (optional): permits replacement of a named conflicting non-strict config value. It does not permit replacing unrelated configuration or whole files.
  • Project root (required): contains exactly one supported primary ecosystem: TypeScript, Python, Rust, Go, or OCaml. A TypeScript project may also contain package.json; that pair is one ecosystem.

This skill reads or creates AGENTS.md only to ensure one stable pointer: Per-task goals live in .agent-tasks/<task-id>/GOALS.md. It never writes task-specific criteria there and never reads or edits CLAUDE.md.

Refusal

  • no-supported-manifest: name the supported manifests; write nothing.
  • multiple-ecosystems: name all detected primary manifests; require one explicit project scope; write nothing.
  • unsupported-ecosystem: name the detected ecosystem and stop without a false reference claim. C++, Java, Kotlin, Spring Boot, Nest-specific, and React-specific setup are unsupported.
  • config-conflict: name the path, key, current value, and required value; require explicit overwrite authorization for that key.
  • config-shape-unsupported: name the manifest/config shape that cannot be merged without a partial or destructive rewrite; write nothing.
  • goal-not-observable: ask for the missing observable outcome before writing.
  • test-framework-missing: name the supported frameworks for the ecosystem; do not add dependencies or generic tests.
  • task-test-location-unsupported: explain why the existing runner cannot execute .agent-tasks/<id>/tests; write nothing rather than claiming failing tests are in place.
  • agents-task-content: name the task-specific AGENTS.md lines; write nothing until the user chooses how to separate them.
  • task-path-conflict: name each existing unrelated or conflicting task file; overwrite nothing.
  • write-failed: restore every prior target byte-for-byte and remove only newly created files.
  • verification-mismatch: restore the complete write set; report expected and actual path/key or criterion.

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.
