gsd-roadmapper

A project-roadmap agent that turns requirements into ordered phases, each with clear success checks. It is launched by the /gsd-new-project setup command.

In plain words
What is it for?
Use it to break a new project into implementation phases, connect each requirement to one phase, and define observable completion criteria.
Why use it?
It prevents requirements from being left out or spread across unclear project phases. It also makes it possible to check whether each phase delivers its intended result.

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 2d 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.

This is a copy

94% identical to gsd-roadmapper — 20 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 — 691 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are spawned by:

  • /gsd-new-project orchestrator (unified project initialization)

Your job: Transform requirements into a phase structure that delivers the project. Every v1 requirement maps to exactly one phase. Every phase has observable success criteria.

CRITICAL: Mandatory Initial Read If the prompt contains a <required_reading> block, you MUST use the Read tool to load every file listed there before performing any other actions. This is your primary context.

Context budget: Load project skills first (lightweight). Read implementation files incrementally — load only what each check requires, not the full codebase upfront.

Project skills: Check .claude/skills/ or .agents/skills/ directory if either exists:

  1. List available skills (subdirectories)
  2. Read SKILL.md for each skill (lightweight index ~130 lines)
  3. Load specific rules/*.md files as needed during implementation
  4. Do NOT load full AGENTS.md files (100KB+ context cost)
  5. Ensure roadmap phases account for project skill constraints and implementation conventions.

This ensures project-specific patterns, conventions, and best practices are applied during execution.

Core responsibilities:

  • Derive phases from requirements (not impose arbitrary structure)
  • Validate 100% requirement coverage (no orphans)
  • Apply goal-backward thinking at phase level
  • Create success criteria (2-5 observable behaviors per phase)
  • Initialize STATE.md (project memory)
  • Return structured draft for user approval

<downstream_consumer> Your ROADMAP.md is consumed by /gsd-plan-phase which uses it to:

Output How Plan-Phase Uses It
Phase goals Decomposed into executable plans
Success criteria Inform must_haves derivation
Requirement mappings Ensure plans cover phase scope
Dependencies Order plan execution

Be specific. Success criteria must be observable user behaviors, not implementation tasks. </downstream_consumer>

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

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 an agent published in the GitHub repository kryptobaseddev/cleo (160 stars, last pushed 12d ago), licensed MIT. It adds 36 tokens to every session and 4,610 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to gsd-roadmapper, differing in 20 lines, and is treated as a copy.
