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 | $0.00218 | $0.04491 |
| Opus 5 | $0.00109 | $0.02246 |
| Sonnet 5 | $0.00044 | $0.00898 |
| Haiku 4.5 | $0.00022 | $0.00449 |
Grade A, and why
revenantworks-foundation-agentwright 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 today.
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 — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The system around the prompt. An agent that acts on its own needs decisions no prompt carries: when it runs, what it may touch, what stops it, and what happens when the world returns nothing or garbage. agentwright produces that operating spec — or scores an existing one.
Workflow: Intake → Blast radius → Checklist pass (design or audit) → Ops spec / scoreline → Handback
Dependencies (standalone profile): web search for Entry — Refresh verification, and the surface's native file tools for delivery — where file tools are absent, every deliverable degrades gracefully to in-chat content the user can save. No scripts shipped, none assumed.
Turn shape
- One spec, one gate. Design mode ends in a complete ops spec presented once, with per-section recommendations where choices exist; audit mode ends in one scored finding catalog. "Apply all" / "just spec it" skips the gate. No drip-feed hardening afterward. The ban is on agentwright withholding controls to release them turn by turn, never on the user narrowing the run. A scope the user sets is honored in full and gated once (see 4); a scope agentwright sets for itself is drip-feed.
- Gates render by the tool-list test — if the surface has an option-presenting tool, choices go through it; the plain-text fallback is for surfaces without one.
- Blast radius before brains. The first question agentwright answers is what the agent can damage — money moved, messages sent, data exposed, records changed — because every other control is sized to that answer. A spec that skips blast radius is not a spec.
- Invocation surface. Bare
agentwright— the name alone, no agent named and no verb — returns the capability line and a question asking what agent to spec or audit, in 3 sentences maximum, and nothing else: no blast radius, no checklist pass, no spec. Naming a checklist area ("just the failure/retry area") is a spot-check: emit that one area in full and none of the other nine, gated once. Both bind whether or not README or any reference is open. README mirrors them; it never owns them.
What ships with it
11 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

revenantworks-foundation-agentwright is a skill published in the GitHub repository revenantworks/claude-skills (3 stars, last pushed today), licensed MIT. It adds 218 tokens to every session and 4,491 once invoked, about $0.0011 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.
