frenchie-method

A structured workflow for developing software with AI assistance, covering requirements, tests, architecture, implementation, review, release checks, and project documents.

In plain words
What is it for?
Use it to run requirement and quality analysis, design tests, guide implementation, review changes, perform release checks, and store development artifacts.
Why use it?
It gives a team a consistent path from an idea to a release instead of leaving each development step disconnected.

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

frenchie-method 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 yesterday.

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 — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Frenchie Method

Frenchie Method is the workflow/process layer. Frenchie Kit is the file and multimodal capability layer.

  • /frenchie-method starts Method orchestration.
  • /frenchie remains Frenchie Kit and must not be treated as a Method alias.
  • Text-only Method usage does not require a Frenchie API key.
  • Install skills alongside MCP tools with npx @lab94/frenchie install.
  • Codex Desktop exposes slash entrypoints by skill name, not by reading .claude/commands/*.md. The Codex installer creates wrapper skills such as requirement, qa-analysis, and implement so /requirement can work after restart. If a host does not expose those wrappers, treat no-slash requests such as Frenchie Method requirement ... as the corresponding Method command.

Runtime Defaults

Use .frenchie/method.config.json when present. If it is missing, continue with production-safe defaults:

  • artifacts: .frenchie/docs/feature
  • knowledge: .frenchie/docs/knowledge
  • worktrees enabled by default
  • orchestrator recommends the full sequence; direct commands warn-and-continue
  • artifact language: auto
  • cross-model review: off
  • skill triggers: command-key skeleton is present; defaults are empty because installed skill sets vary by agent

Command Routing

The slash form below is the canonical Method command name. Claude Code reads command files directly. Codex uses wrapper skills with the same names. If the host agent does not support either path, recognize the same names without the leading slash when the user clearly asks to use Frenchie Method.

Tier 1 commands:

/frenchie-method
/method-check
/prepare-feature
/documenting-code
/requirement
/qa-analysis      alias /test-case
/design           conditional
/security-review
/sa-analysis      alias /implementation-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.
