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

vibetags com-example-service-EvidenceBasedShowcase.instructions.md 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 5d 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

Copilot Instructions for EvidenceBasedShowcase

Generated — Edit The Source

  • Rule: Machine-generated. Read it, never write it — hand edits are silently overwritten.
  • Generated from: src/main/resources/openapi/checkout.yaml
  • Edit instead: src/main/resources/openapi/checkout.yaml
  • Regenerate with: mvn generate-sources

Rules for field settledOrderIds

  • Rule: This looks removable but is deliberate. Refactor only while the invariant holds.
  • Invariant: Settled orders stay in the list until the reconciliation job drains it
  • Breaks if changed: Clearing eagerly drops in-flight settlements and silently under-reports revenue
  • Audit: Not a defect — do not flag.

Rules for method totalWithTax

  • Rule: The following compile here but are prohibited at this element.
  • Forbidden: java.lang.System.out, java.util.Date, java.lang.Double
  • Use instead: the injected org.slf4j.Logger, java.time.Instant, and java.math.BigDecimal
  • Reason: Console output bypasses structured logging; Date and Double are unsafe for money and time

Rules for method refreshCartBadge

  • Rule: Safe on exactly one thread. This is NOT thread-safety — never add locks to "fix" it; marshal the call instead.
  • Affinity: NAMED (checkout-ui)
  • Marshal via: CheckoutDispatcher.runOnUiThread
  • Symptom if violated: Cart totals render stale under load; no exception is thrown

Rules for field CATALOG_VERSION

  • Rule: Free to change, but every mirror must change in the same commit.
  • Mirrors: pom.xml:, README.md version badge, docs/CHANGELOG.md
  • Reason: The release version is duplicated across build config, docs, and the badge
  • Enforced by: ProjectFactsConsistencyTest
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.
