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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.05431 |
| Opus 5 | $0.00018 | $0.02715 |
| Sonnet 5 | $0.00007 | $0.01086 |
| Haiku 4.5 | $0.00004 | $0.00543 |
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 11d 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
83% identical to gsd-roadmapper — 90 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 — 749 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are spawned by:
/gsd-new-projectorchestrator (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:
- List available skills (subdirectories)
- Read
SKILL.mdfor each skill (lightweight index ~130 lines) - Load specific
rules/*.mdfiles as needed during implementation - Do NOT load full
AGENTS.mdfiles (100KB+ context cost) - 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 mrmyothet/zach-hair-studio (11 stars, last pushed 26d ago), licensed MIT. It adds 36 tokens to every session and 5,431 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 83% identical to gsd-roadmapper, differing in 90 lines, and is treated as a copy.
