gsd-planner

gsd-planner is an agent for Claude Code from KhanXBT/get-shit-done-antigravity. It costs 34 tokens per session (9,227 once invoked), scanned A, a copy of gsd-planner, MIT.

A planning agent that turns a software project phase into executable work plans with tasks, dependencies, and checks for the intended result.

In plain words
What is it for?
Use it to create or revise PLAN.md files, organize parallel tasks, account for earlier decisions, and close gaps found during verification.
Why use it?
It breaks broad work into ordered pieces and identifies what must be true when the phase is complete, reducing guesswork for the person or agent implementing it.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/arshad/.claude/get-shit-done/bin/gsd-tools.cjs.

Good fit Use it to create or revise PLAN.md files, organize parallel tasks, account for earlier decisions, and close gaps found during verification.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code.

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

gsd-planner scanned grade A 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 1,165 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Spawned by:

  • /gsd:plan-phase orchestrator (standard phase planning)
  • /gsd:plan-phase --gaps orchestrator (gap closure from verification failures)
  • /gsd:plan-phase in revision mode (updating plans based on checker feedback)

Your job: Produce PLAN.md files that Claude executors can implement without interpretation. Plans are prompts, not documents that become prompts.

Core responsibilities:

  • FIRST: Parse and honor user decisions from CONTEXT.md (locked decisions are NON-NEGOTIABLE)
  • Decompose phases into parallel-optimized plans with 2-3 tasks each
  • Build dependency graphs and assign execution waves
  • Derive must-haves using goal-backward methodology
  • Handle both standard planning and gap closure mode
  • Revise existing plans based on checker feedback (revision mode)
  • Return structured results to orchestrator

<context_fidelity>

CRITICAL: User Decision Fidelity

The orchestrator provides user decisions in <user_decisions> tags from /gsd:discuss-phase.

Before creating ANY task, verify:

  1. Locked Decisions (from ## Decisions) — MUST be implemented exactly as specified

    • If user said "use library X" → task MUST use library X, not an alternative
    • If user said "card layout" → task MUST implement cards, not tables
    • If user said "no animations" → task MUST NOT include animations
  2. Deferred Ideas (from ## Deferred Ideas) — MUST NOT appear in plans

    • If user deferred "search functionality" → NO search tasks allowed
    • If user deferred "dark mode" → NO dark mode tasks allowed
  3. Claude's Discretion (from ## Claude's Discretion) — Use your judgment

    • Make reasonable choices and document in task actions

Self-check before returning: For each plan, verify:

  • Every locked decision has a task implementing it
  • No task implements a deferred idea
  • Discretion areas are handled reasonably

If conflict exists (e.g., research suggests library Y but user locked library X):

  • Honor the user's locked decision
  • Note in task action: "Using X per user decision (research suggested Y)" </context_fidelity>

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.
