What it does

Ab Start Roadmap is an agent skill from ayoubben18/ab-method. Execute a roadmap autonomously to completion — the layer above start-task. Use when a roadmap's tasks are planned and you want them run in dependency order, with independent tasks optionally in parallel. Verifies the dependency tree is planned before running; stops if a needed task has no plan. Executor only.

Its SKILL.md is about 780 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: A workflow system for Claude Code and Codex. It grills a problem into a domain-grounded plan, then either drives it through test-driven missions you review one at a time, or… The licence is MIT.

When your agent uses it

  • A roadmaps tasks are planned and you want them run in dependency order
  • With independent tasks optionally in parallel

Example prompts

  • “/ab-start-roadmap”

Requirements

  • Node.js

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. The project root (the current working directory) first. If /.ab-method/... exists, use it. A project's own .ab-method/structure/index.yaml…
  2. Only if the project has no such file (AB Method installed as a plugin rather than with npx ab-method), read the bundled copy…

What it can do on your machine

Read from SKILL.md and the folder at commit 85946e3. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ab Start Roadmap loads about 781 tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 386 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~82
When it runs · the whole SKILL.md, loaded when a task matches
~781

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Execute a roadmap autonomously to completion — the layer above start-task. Use when a roadmap's tasks are planned and you want them run in dependency order, with independent tasks optionally in parallel. Verifies the dependency tree is planned before running; stops if a needed task has no plan. Executor only.

This skill runs the AB Method start-roadmap workflow.

Follow the workflow defined in .ab-method/core/start-roadmap.md exactly — it contains the dependency-tree verification gate, the parallelism-mode prompt, the topological execution loop, and the failure/resume rules.

Before doing anything, check .ab-method/structure/index.yaml. It defines where roadmaps and tasks are stored and how they reference each other. Paths are user-configurable; never hardcode them.

Locating .ab-method/. Every .ab-method/... path — here and inside the workflow files — is resolved in this order:

  1. The project root (the current working directory) first. If <project>/.ab-method/... exists, use it. A project's own .ab-method/structure/index.yaml is how it customises its paths, so it always wins — check for it even when the bundled copy is right there.
  2. Only if the project has no such file (AB Method installed as a plugin rather than with npx ab-method), read the bundled copy: ../../../.ab-method/ relative to this SKILL.md.

The bundled copy is read-only reference material. Every path the index or a workflow names (docs/..., CONTEXT.md, UBIQUITOUS_LANGUAGE.md, ...) is relative to the project root — never to the folder the bundled files live in. Never write inside that folder.

Key points: build the DAG from roadmap.md; verify the whole dependency tree before executing — a task is runnable only if it has a real plan (progress-tracker.md with missions) and its deps are done; if a needed dependency is unplanned, STOP and tell the user to plan it first with ab-create-task. No "Proceed?" prompt — it starts on invocation. Parallelism comes from the invocation: sequential by default (safe, portable), git worktrees only when explicitly asked. Each task runs by ab-start-task rules (subagent per mission, tdd, commit per green mission). On Codex the parent orchestrates flat — one subagent level, no agent-in-agent — because Codex's spawn_agent is one level deep and cannot nest (NESTING_UNAVAILABLE); never design a task as a subagent that spawns mission-subagents here. (Claude Code, which can nest, defaults to the nested task-subagent → mission-subagent shape for context isolation — that's the Claude path, not this one.) Update roadmap.md statuses as tasks complete; re-runs resume from the frontier. Re-runnable / incremental: a task NEEDS WORK whenever its progress-tracker.md has any unchecked mission, regardless of its status: field — so after a completed roadmap, ab-extend-task can add missions (reopening those tasks), and re-running executes only the tasks with new work, in dependency order, skipping finished ones. Never define or reshape tasks — this is executor only.
