fire-double-check

fire-double-check is a command for coding agents from ThierryN/fire-flow. It costs 7 tokens per session (2,861 once invoked), scanned A, original, MIT.

A validation command for checking whether current work is really complete before claiming it is done.

In plain words
What is it for?
Use it to verify a feature, phase, pull request, or other work item, with optional fast, deep, focused, or fix-attempt modes.
Why use it?
It requires evidence from checks such as tests, security review, type checking, or builds, reducing unsupported completion claims.

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

fire-double-check scanned grade A with 1 finding 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.

Verify before you claim victory


Purpose

A rigorous validation command inspired by superpowers:verification-before-completion. Prevents false completion claims by requiring evidence-based verification. Integrates with WARRIOR honesty protocols to ensure claims match reality.


Arguments

arguments:
  target:
    required: false
    type: string
    description: "What to verify - defaults to current work"
    examples:
      - "/fire-double-check"  # Verify current work
      - "/fire-double-check 'login feature'"
      - "/fire-double-check phase 2"
      - "/fire-double-check PR#45"

optional_flags:
  --deep: "Run extended verification including edge cases"
  --fast: "Quick sanity check only (not recommended)"
  --focus: "Specific area: tests, security, types, build"
  --fix: "Attempt to fix issues found (default: report only)"

Target: {target or "Current Work"}
Mode: Evidence-Based Verification

Analyze what's being claimed:

## Claims to Verify

Based on context, the following claims need verification:

| # | Implicit Claim | Evidence Required |
|---|----------------|-------------------|
| 1 | Code compiles | Build output |
| 2 | Tests pass | Test runner output |
| 3 | Feature works | Demo or test |
| 4 | No regressions | Full test suite |
| 5 | Types are correct | TypeScript output |
