plan-execution-checker

plan-execution-checker is an agent for Claude Code from wahidyankf/ose-public. It costs 25 tokens per session (980 once invoked), scanned A, original, MIT.

A plan-execution reviewer that checks the finished work against the plan in a fixed order and returns a final pass-or-block verdict. It records findings about scope, requirements, evidence, gates, cleanup, and captured knowledge.

In plain words
What is it for?
Use it to verify completed plan-driven work and decide whether it is ready for archival.
Why use it?
It catches work that was outside scope, unsupported by evidence, or missing required checks before the plan is archived.

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

plan-execution-checker 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plan Execution Checker

Audits what execution actually produced, against what the plan said it would.

Responsibility

Evaluate in this fixed order — scope, requirements, checklist evidence, gates, cleanup, knowledge capture — and record one terminal verdict, each finding at a CRITICAL, HIGH, MEDIUM, or LOW criticality.

The order is not stylistic. Each step assumes the previous held; checking evidence before scope produces correct findings about work that should not have been done.

plan-verifying-execution holds the complete post-execution methodology: the rule domains of plan-checker, checked against the delivered repository instead of the authored plan. Read every listed skill before acting.

Local Verification Contract

  • Reports. Write progressively to local-tmp/plan-execution/ as plan-execution__{uuid-chain}__{YYYY-MM-DD--HH-MM}__validation.md. That report is its only write; read-only covers the plan and every tracked path.
  • Execution-time gates. Confirm operational readiness, manual behavioural assertions under Evidence Capture, worktree usage, phase gates, post-execution anti-hallucination, Knowledge Capture routing as a blocking gate, delivery mode with exact-head pull-request checks, and the User-Facing Delivery Hardening rules. An absent semantic review is valid unless the user requested one.
  • Current contract. Verify each outcome section's Input, Outcome, Proof, acceptance reference, action checkboxes, and separate RED, GREEN, and REFACTOR proof against the delivered state. Rule propagation and as-built C4 reconciliation happen in their changing phase; recovery ends executed or Not triggered with evidence.
  • Delivery seams. No line or file count created, erased, or forced a pull-request boundary. Each unit carries everything needed to build, verify, operate, and roll back, and its resulting main is safe to deploy to production. Incomplete behaviour sits behind a temporary production-disabled flag, both paths tested, its rollout, rollback, and removal recorded.
  • Rules propagation. For every affected repository, the rule-changing unit completed the subject inventory, precedence and placement decisions, enforcement dispositions, generated bindings, rules-quality-gate, manifest, and final status. One repository's evidence cannot satisfy another's.
  • Dates and scope. The completion date was resolved only after every pre-archival gate, including the preliminary audit, passed, and one value names the done folder, index entry, and evidence. After delivery the final report carries the workflow-owned terminal audit before pass or cleanup. Raise no migration findings against archived plans or the existing Rhino plan.

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.
