decompose

decompose is a skill for Claude Code, Codex from synaptiai/agent-capability-standard. It costs 32 tokens per session (2,681 once invoked), scanned A, original, Apache-2.0.

A planning tool that breaks a large goal into smaller subgoals with dependencies and testable acceptance criteria. Acceptance criteria are the conditions that show a piece of work is finished correctly.

In plain words
What is it for?
Use it to create work breakdowns, define requirements, separate phases or components, and set clear checks for completion.
Why use it?
It makes complex work easier to understand, assign, and verify. It also exposes missing steps and requirements before implementation begins.

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

decompose 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 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.

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

Intent

Break down a complex goal into smaller, manageable subgoals with clear boundaries, dependencies, and acceptance criteria. Enable parallel work and incremental progress.

Success criteria:

  • Goal fully decomposed (no gaps)
  • Subgoals are independently verifiable
  • Dependencies are explicit
  • Acceptance criteria are testable
  • Decomposition depth is appropriate

Compatible schemas:

  • schemas/output_schema.yaml

Inputs

Parameter Required Type Description
goal Yes string or object The goal to decompose
depth No integer Maximum decomposition depth (default: 3)
constraints No object Boundaries, limitations, scope
granularity No string Target size: epic, story, task (default: story)
context No object Background information

Procedure

  1. Understand the goal: Clarify what needs to be achieved

    • Parse the goal statement
    • Identify success criteria
    • Note implicit requirements
    • Determine scope boundaries
  2. Identify major components: Find natural divisions

    • Functional areas
    • Phases or stages
    • User journeys
    • Technical layers
  3. Create subgoals: Define each component

    • Clear, specific objective
    • Bounded scope
    • Measurable outcome
    • Independent when possible
  4. Define dependencies: Map relationships

    • Which subgoals block others?
    • Which can proceed in parallel?
    • Are there shared resources?
    • Create dependency graph
  5. Add acceptance criteria: Specify done conditions

    • Testable conditions
    • Measurable outcomes
    • Quality requirements
    • Edge case handling
  6. Validate completeness: Check coverage

    • Do subgoals cover entire goal?
    • Any gaps or overlaps?
    • Are boundaries clear?
    • Is granularity consistent?
  7. Recurse if needed: Decompose large subgoals

    • Check against target granularity
    • Decompose subgoals that are too large
    • Maintain consistent depth
    • Stop when atomic enough

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

decompose is a skill published in the GitHub repository synaptiai/agent-capability-standard (4 stars, last pushed 4d ago), licensed Apache-2.0. It adds 32 tokens to every session and 2,681 once invoked, about $0.0002 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.
