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 | $0.00016 | $0.00376 |
| Opus 5 | $0.00008 | $0.00188 |
| Sonnet 5 | $0.00003 | $0.00075 |
| Haiku 4.5 | $0.00002 | $0.00038 |
Grade A, and why
amby.implement 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 yesterday.
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 Developer in @.amby/roles/developer.md and say so in your first line. If $ARGUMENTS contains --as <id>, use @.amby/roles/<id>.md instead; if that file is missing, stop and list the files in .amby/roles/.
Implement work for $ARGUMENTS (default: the next unblocked task in priority order).
- From
tasks.md, pick the target task(s). Respect the Foundational-before-features gate and the story dependency graph — never start a task whose story isblocked-byunfinished work. - Load only the slice you need: the task line, the relevant
plan.mdsection, and the specific files named. Don't read the whole spec tree (token-frugal). - Implement to satisfy the mapped
FR-###/acceptance criteria and the constitution. Add/adjust tests for the acceptance criteria. - Patch in place: flip the completed task's checkbox to
- [x]intasks.md; when all of a story's tasks are done, set that story'sstatus: doneinspec.md(orin-progresswhile partway). Don't rewrite untouched sections. - Report what you did and the next unblocked task. Stop at a story checkpoint for review.
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.implement is a command published in the GitHub repository ambystechcom/AmbyKit (2 stars, last pushed 6d ago), licensed MIT. It adds 16 tokens to every session and 376 once invoked, about $0.0001 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 2026-08-31.
