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 | $0.00060 | $0.00715 |
| Opus 5 | $0.00030 | $0.00358 |
| Sonnet 5 | $0.00012 | $0.00143 |
| Haiku 4.5 | $0.00006 | $0.00072 |
Grade A, and why
actor-template 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Actor Template
An Actor prescribes how to act (the Goal/Input/Steps/Output/Constraints shape below). It is distinct from Knowledge, which encodes what is true (rules, patterns, references). The two never mix in one file — see ground-rules for the truth half.
The five required sections
Every Actor file must contain exactly these five sections, in this order, no renames, no merges:
- Goal — what success looks like, in one sentence. Failure mode without it: the actor wanders.
- Input — what the actor needs from the caller. Failure mode without it: the actor invents data.
- Steps — numbered, in order. Each Step produces an observable result (a written file, a returned value, a confirmed message). Failure mode without it: a Step without observable result hides ambiguity.
- Output — what the actor returns when done. Failure mode without it: callers cannot tell success from in-progress.
- Constraints — what the actor must not do; the boundary. Failure mode without it: the actor over-reaches.
One worked example — Summarize a pull request
Goal: Produce a 3-bullet summary of a pull request so a reviewer can decide whether to dig deeper in under 30 seconds.
Input: The PR number; the repository (owner/name).
Steps:
- Fetch the PR title, description, and changed-files list via
gh pr view <number> --repo <owner/name>. Observable result: the title and description are quoted verbatim in the working scratchpad. - Identify the largest changed file by diff size via
gh pr diff <number> --repo <owner/name> | diffstat. Observable result: filename + diff-line count noted. - Write three bullets: (a) what the PR claims to do, (b) the largest mechanical change, (c) any test changes. Observable result: three bullets written to the output, each ≤ 1 line.
Output: Three bullets, ≤ 1 line each, prefixed with the PR number (e.g., #123:).
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.

actor-template is a skill published in the GitHub repository NVZver/claude-marketplace (1 stars, last pushed 15d ago), licensed MIT. It adds 60 tokens to every session and 715 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 2026-08-31.
