A planning tool that turns a project's vision and architecture into milestones and an ordered queue of product requirements. A PRD is a document describing one piece of work and its expected result.

Use it to create roadmaps, divide work into milestones and PRDs, order tasks by dependency, and generate the project's roadmap files.

It gives a project a clear execution order and records which tasks depend on earlier work, instead of leaving planning as an unstructured list.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00039	$0.02760
Opus 5.5	$0.00016	$0.01104
Sonnet 5.5	$0.00008	$0.00552
Haiku 4.5	$0.00004	$0.00276

Security

Grade A, and why

roadmap 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 2mo 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.

Roadmap Skill

Plan project execution by creating milestones and organizing PRDs into an executable queue.

Workspace Mode Note

When running in workspace mode, all paths are relative to .aha-loop/ directory:

Vision analysis: .aha-loop/project.vision-analysis.md
Architecture: .aha-loop/project.architecture.md
Roadmap: .aha-loop/project.roadmap.json
PRD files: .aha-loop/tasks/

The orchestrator will provide the actual paths in the prompt context.

The Job

Read project.vision-analysis.md and project.architecture.md
Decompose project into milestones
Break each milestone into PRDs
Order PRDs by dependencies
Output project.roadmap.json
Generate initial PRD files in tasks/

Milestone Strategy

Standard Milestone Structure

Milestone	Focus	Goal
M0: Foundation	Project scaffolding, CI/CD, tooling	Development environment ready
M1: MVP	Core features only	Minimal usable product
M2: Essential	Important features	Feature-complete for basic use
M3: Enhanced	Nice-to-have features	Polished product
M4: Optimization	Performance, UX polish	Production-ready

Milestone Sizing

Each milestone should:

Be completable in a reasonable timeframe
Have 3-7 PRDs (avoid too many or too few)
Deliver tangible, testable value
Build on previous milestones

PRD Decomposition

From Features to PRDs

For each milestone, break down features into PRDs:

Milestone: M1 - MVP
├── PRD-001: Project Scaffolding
├── PRD-002: Database Schema
├── PRD-003: Core Data Models
├── PRD-004: Basic API Endpoints
└── PRD-005: Minimal UI

PRD Sizing

Each PRD should:

Take 1-5 Aha Loop iterations (5-25 stories)
Focus on one coherent feature area
Be independently testable
Not depend on unfinished PRDs

PRD Ordering

Order PRDs by dependencies:

Infrastructure first - Project setup, database, auth
Backend before frontend - APIs before UI that uses them
Core before optional - Must-have before nice-to-have
Data before presentation - Models before views

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.

roadmap is a skill published in the GitHub repository YougLin-dev/Aha-Loop (178 stars, last pushed 9mo ago), licensed MIT. It adds 39 tokens to every session and 2,760 once invoked, about $0.0002 per session on Opus 5.5. 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.
