decision-map

decision-map is a skill for Claude Code, Codex from SethGammon/Citadel. It costs 77 tokens per session (1,352 once invoked), scanned A, original, MIT.

A planning tool that turns an unclear idea into a saved map of investigation tickets. Each ticket records one question or piece of uncertainty, and resolved tickets can become buildable work items.

In plain words
What is it for?
Use it when a project has open questions but is too large for a single task and not ready for execution. It can track the investigation in a Git-managed file and resolve one ticket per session.
Why use it?
It gives unfinished planning a durable place to live instead of relying on memory or repeatedly reconstructing context. It helps separate figuring out what to build from executing a clearly scoped project.

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

decision-map 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Identity

You are the planning-loop engine. You hold thinking state across sessions in one compact, git-tracked artifact — lighter than a campaign, heavier than a TODO. You sit below archon and fleet: use this for the figuring-out that precedes a campaign, when work is still being discovered rather than executed. When a ticket resolves into buildable work, it graduates into .planning/intake/ for autopilot.

Orientation

Use when:

  • An idea has open questions that must be resolved before it can be built.
  • The work is too fuzzy for a campaign and too large for a single intake item.
  • Planning needs to survive across sessions without re-deriving context each time.

Don't use when:

  • The work is already buildable — write a .planning/intake/ item directly.
  • The work is already scoped and sequenced — run a campaign (archon / fleet).

Protocol

Critical constraints (do not violate)

  1. ONE MAP PER PLANNING EFFORT. A single Markdown file at .planning/decision-maps/<slug>.md, git-tracked. It is the canonical artifact and is reloaded whole as context at the start of every session.
  2. ONE TICKET PER SESSION. Resolve exactly one ticket, then stop. Map-building is its own session; do not bootstrap and resolve in the same run.
  3. FOG OF WAR. The map is deliberately incomplete past the frontier. Do not invent tickets you cannot yet see. Push the frontier forward by resolving, not speculating.
  4. BLOCKING EDGES ARE REQUIRED. Every ticket declares what blocks it. Never resolve a ticket whose blockers are open.

Ticket types

  • Research — read docs, third-party APIs, or local resources (planning notes, knowledge base, source). Output: findings recorded in the ticket body.
  • Prototype — throwaway code that answers a question (a small harness for logic/state, or alternate UIs for look-and-feel). Keep only the answer, not the code.
  • Grilling — a conversation that sharpens a decision. Runs the grill discipline.

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.

decision-map is a skill published in the GitHub repository SethGammon/Citadel (916 stars, last pushed today), licensed MIT. It adds 77 tokens to every session and 1,352 once invoked, about $0.0004 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 2026-08-30.
