In plain words
What is it for?
Verifying review approval, running project tests and builds, and comparing the requested work with changed files.
Why use it?

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-delivery 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 4d 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.

Validation Checks

Check 1: Review Status

function checkReviewStatus(reviewResults) {
  if (!reviewResults) return { passed: false, reason: 'No review results' };
  if (reviewResults.approved) return { passed: true };
  if (reviewResults.override) return { passed: true, override: true };
  return { passed: false, reason: 'Review not approved' };
}

Check 2: Tests Pass

# Detect test runner and run
if grep -q '"test"' package.json; then
  npm test; TEST_EXIT_CODE=$?
elif [ -f "pytest.ini" ]; then
  pytest; TEST_EXIT_CODE=$?
elif [ -f "Cargo.toml" ]; then
  cargo test; TEST_EXIT_CODE=$?
elif [ -f "go.mod" ]; then
  go test ./...; TEST_EXIT_CODE=$?
else
  TEST_EXIT_CODE=0  # No tests
fi

Check 3: Build Passes

if grep -q '"build"' package.json; then
  npm run build; BUILD_EXIT_CODE=$?
elif [ -f "Cargo.toml" ]; then
  cargo build --release; BUILD_EXIT_CODE=$?
elif [ -f "go.mod" ]; then
  go build ./...; BUILD_EXIT_CODE=$?
else
  BUILD_EXIT_CODE=0  # No build step
fi

Check 4: Requirements Met

async function checkRequirementsMet(task, changedFiles) {
  const requirements = extractRequirements(task.description);
  const results = [];

  for (const req of requirements) {
    const implemented = await verifyRequirement(req, changedFiles);
    results.push({ requirement: req, implemented });
  }

  return {
    passed: results.every(r => r.implemented),
    requirements: results
  };
}

function extractRequirements(description) {
  const reqs = [];
  // Extract bullet points: - Item
  const bullets = description.match(/^[-*]\s+(.+)$/gm);
  if (bullets) reqs.push(...bullets.map(m => m.replace(/^[-*]\s+/, '')));
  // Extract numbered items: 1. Item
  const numbered = description.match(/^\d+\.\s+(.+)$/gm);
  if (numbered) reqs.push(...numbered.map(m => m.replace(/^\d+\.\s+/, '')));
  return [...new Set(reqs)].slice(0, 10);
}

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.
