Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00065 | $0.00494 |
| Opus 5 | $0.00032 | $0.00247 |
| Sonnet 5 | $0.00013 | $0.00099 |
| Haiku 4.5 | $0.00006 | $0.00049 |
Grade A, and why
ab-start-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 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.
What it actually says
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.
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.
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.

ab-start-roadmap is a skill published in the GitHub repository ayoubben18/ab-method (189 stars, last pushed 4d ago), licensed MIT. It adds 65 tokens to every session and 494 once invoked, about $0.0003 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.
