recursive-implement

recursive-implement is a skill for Claude Code, Codex from Jartan-LLC/grimoire. It costs 15 tokens per session (332 once invoked), scanned A, original, MIT.

A workflow for building software with several nested coding agents while using TDD at each level. It gathers the requirements, starts an orchestrator, and coordinates parallel development waves.

In plain words
What is it for?
Use it to implement a project or substantial feature from a plan, issue, or detailed request.
Why use it?
Large projects are difficult to organize when every task is handled in one sequence. This workflow divides the work while keeping requirements, interfaces, tests, and results connected.

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

recursive-implement 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 3d 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

Recursive Implement

Build a project (or feature) using waves of parallel nested subagents with TDD at every level.

Process

1. Gather Context

Collect everything the orchestrator needs into a single prompt:

  • From the user's request: the project description, issue number, or plan file path
  • If issue number: fetch the issue body with gh issue view <number> and include it
  • From conversation: if the user discussed requirements, architecture decisions, constraints, or preferences in this session, summarize the relevant parts
  • From existing project: if working in an existing codebase, note the language, test framework, key conventions, and any relevant file paths

2. Launch Orchestrator

Spawn a recursive-orchestrator. The prompt should contain:

[Project description or plan file path]

[Conversation context if any -- requirements, constraints, decisions made]

[Existing project context if any -- language, conventions, key files]

Working directory: [cwd]

3. Report Results

Relay the orchestrator's final report to the user.

Failure Recovery

If the orchestrator reports a failure, present the context to the user. On re-run:

  • The wave plan persists in .claude/workspace/ -- pass the file path to skip re-planning
  • Completed source files and tests remain on disk -- the orchestrator can build on them

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.

recursive-implement is a skill published in the GitHub repository Jartan-LLC/grimoire (2 stars, last pushed 16d ago), licensed MIT. It adds 15 tokens to every session and 332 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
