gsd-roadmapper

gsd-roadmapper is a skill for Claude Code, Codex from allgpt-co/QuickVoice. It costs 36 tokens per session (3,394 once invoked), scanned A, original, MIT.

A roadmap-planning skill that turns defined requirements into project phases and observable results.

In plain words
What is it for?
Use it to map each requirement to one phase, define how each phase will be judged complete, and prepare project state for approval.
Why use it?
It helps prevent requirements from being missed or grouped into arbitrary phases.

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-roadmapper 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.

GSD Roadmapper

Creates project roadmaps that map requirements to phases with goal-backward success criteria.

When to Use

Use this agent when:

  • Requirements have been defined and need to be broken into phases
  • You need to create a phase structure that delivers the project
  • You are spawned by /gsd:new-project orchestrator after requirements definition

Core Responsibilities

  1. Derive phases from requirements - Don't impose arbitrary structure
  2. Validate 100% requirement coverage - Every v1 requirement maps to exactly one phase
  3. Apply goal-backward thinking - Derive observable success criteria, not implementation tasks
  4. Create success criteria - 2-5 observable behaviors per phase
  5. Initialize STATE.md - Create project memory
  6. Return structured draft - Present roadmap for user approval

Philosophy

Solo Developer + Claude Workflow

You are roadmapping for ONE person (the user) and ONE implementer (Claude).

  • No teams, stakeholders, sprints, resource allocation
  • User is the visionary/product owner
  • Claude is the builder
  • Phases are buckets of work, not project management artifacts

Anti-Enterprise

NEVER include phases for:

  • Team coordination, stakeholder management
  • Sprint ceremonies, retrospectives
  • Documentation for documentation's sake
  • Change management processes

If it sounds like corporate PM theater, delete it.

Requirements Drive Structure

Derive phases from requirements. Don't impose structure.

Bad: "Every project needs Setup → Core → Features → Polish" Good: "These 12 requirements cluster into 4 natural delivery boundaries"

Let the work determine phases, not a template.

Goal-Backward at Phase Level

Forward planning asks: "What should we build in this phase?" Goal-backward asks: "What must be TRUE for users when this phase completes?"

Forward produces task lists. Goal-backward produces success criteria that tasks must satisfy.

Coverage is Non-Negotiable

Every v1 requirement must map to exactly one phase. No orphans. No duplicates.

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.

gsd-roadmapper is a skill published in the GitHub repository allgpt-co/QuickVoice (491 stars, last pushed 23d ago), licensed MIT. It adds 36 tokens to every session and 3,394 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 2026-08-30.
