design-split-options

design-split-options is a skill for Claude Code, Codex from siarhei-belavus/agent-public. It costs 39 tokens per session (368 once invoked), scanned A, original, MIT.

A planning workflow for comparing two or three different ways to divide a large initiative into tasks. It records the options and recommends one before the detailed task graph is written.

In plain words
What is it for?
Use it when a project is large and its task boundaries or order are still uncertain, especially when separate agents will handle the resulting tasks.
Why use it?
Choosing task boundaries too early can create unclear ownership, hidden dependencies, or poor sequencing. Comparing alternatives exposes those risks 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

design-split-options 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.

What it actually says

design-split-options

Use only when jumping straight to split-initiative would lock in a weak task graph.

Read first

  • ../references/initiative-packet-contract.md
  • ../references/initiative-workflow-contract.md
  • ../references/final-state-authoring-policy.md
  • initiative BRIEF.md, UBIQUITOUS_LANGUAGE.md, DECISIONS.md, INVARIANTS.md, REPO_MAP.md, CONTRACTS.md, OPEN_QUESTIONS.md
  • ../../references/communication-mode.md

Workflow

  1. Enter initiative Status: split_drafting if split drafting has not already started.
  2. Produce 2-3 materially different decomposition options.
  3. Compare options on:
    • ownership clarity
    • coupling
    • validation fit
    • sequencing / uncertainty reduction
    • risk of hidden shared context
    • ease of handing each child to a fresh agent
  4. Recommend one direction explicitly.
  5. Write SPLIT_OPTIONS.md.

Writing rule

Write compared options as candidate final task graphs, not as changelog commentary about prior split attempts.

Do not

  • produce cosmetic variants of the same split
  • defer the recommendation when the evidence already favors one option
  • reference outside Atelier skill files for option-design heuristics

Communication

Honor active caveman mode for user-facing replies per ../../references/communication-mode.md. Keep durable artifacts normal unless the human asks otherwise. Drop caveman for safety/clarity when needed, then resume.

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.
