recursive-planning

recursive-planning is a skill for Claude Code from Jartan-LLC/grimoire. It costs 28 tokens per session (643 once invoked), scanned A, original, MIT.

A method for splitting a large software project into modules and dependency-ordered waves of work.

In plain words
What is it for?
It helps survey a codebase, identify distinct areas, map dependencies, assign work to waves, define module boundaries, and specify deliverables.
Why use it?
It makes parallel development easier by clarifying ownership, dependencies, interfaces, and what must be completed first.

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-planning 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 7d 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.

Recursive Planning

Decomposition Process

  1. Survey -- greenfield or existing? For existing: read README, types, error classes, test setup, conventions. These are constraints.
  2. Identify domains -- genuinely different kinds of work (parsing vs querying vs aggregating vs formatting)
  3. Map dependencies -- which domains need outputs from others? Dependencies flow through interfaces only.
  4. Assign waves -- no dependencies -> Wave 1. Depends on Wave 1 -> Wave 2. Wave 0 is always contracts/setup. Integration is final wave.
  5. Assign scopes -- each module gets a directory or file set. Zero overlap between parallel modules.
  6. Specify conventions -- language, test framework, type system, DI pattern, path handling, package manager
  7. Plan deliverables -- README, CHANGELOG, --version, runtime version access, coverage config

Module Split Criteria

See recursive-development skill for split principle and examples. Goal: natural, best-practice file structure.

Contract Guidance

Wave 0 agent designs contracts. The plan specifies what they should cover:

  • Enumerate capabilities -- list all operations/formats/modes, not just common ones
  • Error handling -- "Parsers yield Record | ParseError" not "Parsers raise on bad input"
  • Batch interfaces -- "Aggregator takes list[AggregationSpec]" not single-item
  • Injectable I/O -- "Formatters accept a write callable"
  • Types only -- contracts file has protocols, dataclasses, enums, type aliases, constants. No callable stubs.
  • Exception hierarchy -- base exception + subtypes per failure domain
  • Logging -- modules use named loggers, CLI configures at entry point

For existing projects: extend existing contracts, match established patterns.

## Implementation Plan -- `<name>` <description>
### Issue Summary
### Language & Conventions
### Language-Specific Standards
(Standards shaped to this project's language and domain -- specifics that all agents must follow.
These go beyond generic conventions. Think about what a senior developer in this language would
insist on in a code review.)
### Existing Patterns (existing projects only)
### Chosen Approach

## Wave 0: Contracts & Project Setup
## Wave 1: <name> (N parallel)
### Module A -- Owns: <scope>, Responsibility: <one line>
## Wave 2: <name>
### Module C -- Owns: <scope>, Depends on: <interfaces>, Responsibility: <one line>
## Wave N: Integration + Documentation (README.md, CHANGELOG.md)

## File Ownership Map
### Complexity: Simple | Moderate | Complex

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-planning is a skill published in the GitHub repository Jartan-LLC/grimoire (2 stars, last pushed today), licensed MIT. It adds 28 tokens to every session and 643 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.
