okhp3-artifact-validation

okhp3-artifact-validation is a skill for Codex from OKHP3/skillz. It costs 70 tokens per session (670 once invoked), scanned A, original, MIT.

A read-only review step for checking whether a project change, research packet, skill, or handoff is ready to be treated as complete.

In plain words
What is it for?
Use it after meaningful work to run available validators and record the artifact path, checks, evidence, warnings, blockers, and next action.
Why use it?
It catches missing checks, unsupported claims, scope problems, and unresolved blockers before others rely on the 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

okhp3-artifact-validation 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 9d 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.

Output contract

Return the artifact path and scope, checks run, status for each check, evidence, blockers, warnings, checks not run, and the next action. A missing validator is NOT RUN or BLOCKED, never PASS. Keep validation read-only unless a separate repair request authorizes a specific change.

Choose checks proportionate to the artifact and consequence.

Mechanical floor

For project-wide or structural work, first identify the project-declared validator and confirm that it exists. Run it from the project root or the location its own instructions require. Do not assume a particular filename, operating system command, or repository layout.

For a skill, also run the host's available skill validator when one is available and confirm its description matches its actual trigger boundary. For code or generated files, run the targeted parser, test, linter, build, or render check appropriate to that format.

Judgment checks

Confirm:

  • the real path and changed scope;
  • unrelated owner work remains intact;
  • factual claims and citations are supportable;
  • evidence tiers are visible where they affect future decisions;
  • no secret, confidential, employer, client, or accidental generated material entered scope;
  • links, names, metadata, and referenced resources exist;
  • the artifact satisfies the current request rather than only its format;
  • remaining uncertainty and the next action are explicit.

Report each meaningful check as PASS, FAIL, WARN, BLOCKED, or NOT RUN. Never convert an unavailable check into a pass. A script pass is a mechanical floor, not a quality or publication verdict.

Changes

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.
