decide

decide is a skill for Claude Code, Codex from danweinerdev/claude-sdd-planner. It costs 48 tokens per session (1,572 once invoked), scanned C, a copy of sdd-decide, MIT.

A command for recording, finding, and updating decisions in a persistent decision ledger, which is a searchable record of agreed project truths.

In plain words
What is it for?
Use it to log a decision, look up the reasoning on a topic, replace an old decision, add a missed entry, or check the ledger for problems.
Why use it?
It gives the team one place to check what was decided and helps replace outdated decisions when the direction changes.

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 C, and why

decide scanned grade C with 1 finding 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 today.

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.

Tells the agent never to refusehighAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

0. An explicit `/decide` is the user asking for the entry — record it. But if the statement plainly fails the admission test (it restates what an artifact already says, or it's an event or one-off disposition), say so in
Origin

This is a copy

91% identical to sdd-decide — 19 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/decide — Decision Ledger

Path Resolution

The plugin directory contains commands/, agents/, and shared/ as siblings. Find it by globbing for **/commands/research/SKILL.md in both the current directory and ~/.claude/plugins/cache/; if multiple versions match, sort them as semantic versions (like sort -V) and use the highest, then strip commands/research/SKILL.md from the match. Resolve the planning root (artifacts) per shared/path-resolution.md in the plugin directory.

When to Use

  • Explicitly record a decision, concept definition, or answered design question as durable truth — a truth that must be findable without knowing which document to open, not a choice a spec or design already states (shared/decision-log.md § Capture, the admission test)
  • Look up what was decided about a topic ("what did we decide about auth?")
  • Reconcile a collision — supersede an old decision with a new one
  • Backfill a decision the automatic capture missed
  • Audit ledger hygiene (/decide check) — stale citations, missed collisions, malformed entries

The convention — entry schema, lifecycle rules, collision procedure — is defined in shared/decision-log.md (single source of truth). Read it before operating on the ledger.

Invocation

/decide <statement>            # Record a decision (default subcommand)
/decide list [tag|scope]       # List entries, optionally filtered
/decide search <term>          # Find entries matching a term
/decide show D-NNNN            # Show one entry with its body section, if any
/decide accept D-NNNN          # Promote a proposed entry to accepted
/decide supersede D-NNNN       # Replace an entry with a new decision
/decide check                  # Hygiene audit of the ledger and its citations

Process

0. Resolve the ledger

Resolve the ledger per shared/decision-log.md § Ledger location: <planning-root>/Decisions/decisions.md when the planning root is inside the repo; <repo-root>/DECISIONS.md when the planning root is external (decisions live with the repo they represent — resolve the repo via shared/path-resolution.md). If missing, create it from shared/templates/decision-log.md (and mkdir -p any needed directory) before proceeding.

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.
