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 5.1 | $0.00028 | $0.00602 |
| Opus 5.5 | $0.00011 | $0.00241 |
| Sonnet 5.5 | $0.00006 | $0.00120 |
| Haiku 4.5 | $0.00003 | $0.00060 |
Grade A, and why
amby-revise 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.
What it actually says
Act as the Product Manager in @.amby/roles/pm.md and say so in your first line. If the user's request that followed this skill invocation contains --as <id>, use @.amby/roles/<id>.md instead; if that file is missing, stop and list the files in .amby/roles/.
Continue the spec (and, optionally, the design) for feature the user's request that followed this skill invocation (default: the current feature).
Context: read only that feature's spec.md (and its ui.md if continuing design) plus the structure
of @.amby/templates/spec.md. This command extends an existing feature — it is not specify
(which starts a new feature) nor clarify (which only resolves [NEEDS CLARIFICATION] markers).
- Resolve the feature dir
specs/NNN-slug/. If it — or itsspec.md— cannot be found, report a clear error and make no changes. - Done-guard. If the
spec.mdfrontmatterstatus:isdone, make no edits: tell the author the feature is complete and to run/amby.specifyfor a new feature. Stop here. - Otherwise continue in place (patch, never regenerate — Principle 3):
- Add new user stories (
US-#), requirements (FR-###), and success criteria (SC-###), each taking the next available number. Preserve every existing id and its text verbatim. - Refine existing items only where the author asked; keep their ids stable.
- New requirements use EARS (SHALL / WHEN / WHILE / IF-THEN / WHERE); new acceptance criteria use
Given/When/Then — consistent with
specify. - Leave any story already marked
status: doneuntouched; you may still add new stories.
- Add new user stories (
- Set the
spec.mdfrontmatterstatus:toin-progress. - Design (optional). If the author is continuing the UI/design and
ui.mdexists, extend it in place, preserving existing sections. Ifui.mddoes not exist, do not create it here — direct the author to run/amby.design. - Keep edits minimal and token-frugal; cite the constitution by principle number where relevant.

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.

amby-revise is a skill published in the GitHub repository ambystechcom/AmbyKit (2 stars, last pushed 4d ago), licensed MIT. It adds 28 tokens to every session and 602 once invoked, about $0.0001 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 2026-08-31.
Other skills, from other repositories
importing-a-codebase
Use when asked to create the initial spec graph for an existing codebase that has source code but no specs. Normally reached via setting-up-a-project.
starting-a-new-project
Use when the workspace is empty, has no code, and the user brings a raw project idea. Normally reached via setting-up-a-project; not for an existing project.
managing-mcp-servers
Use when the user asks to add, change, remove, enable or disable an MCP server, or when an MCP tool is missing, needs sign-in, fails, or was blocked. ThinkRail runs pi in-process, so there is no pi command to call.
todos
Use when the user asks for a shared plan, a task needs at least three substantive execution steps, or a loose TODO is pending. Without an explicit plan request, not for one-shot answers or checks, or one- to two-step work that is not already in the list.
asking-user-questions
Use when composing an askuserquestion round inside a workflow, or when a workflow skill names it at a question step. Shared norms for the tool — not a workflow, nothing to execute.
writing-workflow-skills
Use when adding a new workflow skill to pi-thinkrail-workflow, changing an existing workflow skill's role, trigger, handoff, or structure, or checking a workflow skill against the workflow system's rules. Not for authoring general-purpose skills outside this package.
