OPOS: Skill for Claude Code

.claude/skills/check-result/SKILL.md

check-result is a skill for Claude Code from Koroqe/OPOS. It costs 115 tokens per session (656 once invoked), scanned A, original, MIT.

A maker-and-checker process that requires plans before higher-risk actions and independent checks after work is done.

In plain words
What is it for?
It is for planning risky changes, stating a testable result, assigning a fresh checker, and verifying the result with an independent method.
Why use it?
It prevents unverified claims of completion and requires failed or unverifiable results to remain unresolved or be fixed and checked again.

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

check-result 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 27d 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.

What it actually says

check-result

Follow PROCESS.md (authoritative). Quick facts:

  • Caller = the maker (any agent, or the steward). Checker = a fresh result-checker subagent via Task (subagent_type: result-checker), never the maker's own context.
  • Write the claim as one falsifiable sentence and say how you produced it, so the checker can pick a different method. Vague claims ("it works") are rejected — rewrite them first.
  • Independent methods by risk: R0 — none required; R1 "done" — 1; R2 — at least 2; negative claims about documents, money or obligations — every system the fact could live in, plus a behavioural check; external facts — sources of different types. A process may raise these numbers in its checker: field.
  • R2 = two checks. phase: plan before the action (what changes, how to roll back, how the result will be verified) and phase: result after it. A result FAIL → roll back per the plan.
  • Only PASS unlocks. FAIL → fix and re-check, or report the true state. UNVERIFIABLE → the action stays one class higher (R2 is handled as R3) and missing access is filed as a kind: resource-gap.
  • The checker never lowers a class. If the claim or plan shows an action of a higher class than the maker assumed (e.g. writing a secret, changing access or a schedule — always R3), the verdict is FAIL.
  • Evidence as pointers (path, hash, query, URL, command) — never client figures, correspondence or personal data copied into an issue or chat.
  • A PASS is evidence for the responsible human, not a replacement of their check for client, money and document classes.
  • Report the verdict with its method in the issue comment or task report ("verified: , PASS").
  • Every run writes history/YYYY-MM-DD-<run-id>.md.

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.
