decomposing-work

decomposing-work is a skill for Claude Code from isvlasov/rageatc-oss. It costs 42 tokens per session (2,388 once invoked), scanned A, original, MIT.

A workflow for turning an approved software architecture into a roadmap of separate implementation tasks arranged by dependency. The roadmap is a persistent file that describes the work phases and chunks.

In plain words
What is it for?
Use it to split architecture into ordered work chunks, identify components and integration points, and prepare a roadmap before implementation.
Why use it?
It prevents coding from starting with unclear task boundaries or missing prerequisites, which can lead to misaligned implementations.

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

decomposing-work 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 8d 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 — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Decomposing Work

Converts a confirmed ARCHITECTURE.md into a persistent roadmap of implementation chunks — the decomposition discipline that determines whether developer-agents succeed.

Position: architecting-software (ARCHITECTURE.md) → decomposing-work (ROADMAP.md structure) → enriching-roadmap (acceptance criteria, pattern references) → developer-agent.

Inputs: a confirmed ARCHITECTURE.md and human confirmation to proceed — do not begin autonomously. If the architecture is ambiguous (missing component boundaries, implicit interfaces, unclear data ownership), flag specific gaps to the human before producing chunks. Inferred boundaries produce misaligned briefs.

Output: ROADMAP.md in the project root — header block, global Definition of Done, chunks grouped by phase, per the Templates section. Present the draft as "proposed" and write the final file only after the human confirms.

Not covered: architecture design, enrichment, orchestration, implementation.

Workflow

Step 1: Read the Architecture

Read ARCHITECTURE.md fully and extract four labelled lists:

  • Components — named services, modules, packages, domains
  • Integration surfaces — every API, event contract, shared schema, or data-model interface between components
  • Foundational infrastructure — what must exist before any feature (project scaffold, CI/CD, database setup, auth skeleton, shared types, logging wiring)
  • Cross-cutting concerns — logging, error handling, observability, authentication — only those explicitly described in the architecture

Log anything ambiguous or absent as an open question. Do not proceed with unresolved questions that would force you to infer chunk boundaries.

Step 2: Calibrate Scale

Assess project scale (component count, team size, complexity, workflow tier) and set a target chunk range — this prevents over-decomposition, where brief-develop-review overhead exceeds the project's complexity.

Project scale Target chunks Example
Small (1-2 components, solo dev) 5-12 Personal recipe app, CLI tool
Medium (3-5 components, small team) 10-20 SaaS feature, API service
Large (5+ components, team) 15-40 Platform, multi-service system

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.

decomposing-work is a skill published in the GitHub repository isvlasov/rageatc-oss (9 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 2,388 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.
