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 | $0.00049 | $0.00775 |
| Opus 5.5 | $0.00020 | $0.00310 |
| Sonnet 5.5 | $0.00010 | $0.00155 |
| Haiku 4.5 | $0.00005 | $0.00077 |
Grade A, and why
cyber-exercise-control 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.
How it starts
The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cyber Exercise Control
Priority: P0 (CRITICAL)
Coordinate a bounded exercise; control safety and adjudication handoffs without performing attacks or certifying compliance.

Workflow
- Confirm approved plan, mode per step (
analysis,replay,isolated-lab-validation,defensive-verification), authorization, exclusions, runtime support, and synthetic boundaries. - Manage execution states using StepResult schema (
planned,eligible,running,completed,blocked,stopped,failed,dependency-blocked). - Publish schedule and injects with step ID, trigger, expected channel, limits, and abort conditions.
- Stop immediately on expiry, drift, unsafe impact, data exposure, or operator signal; host stop dominates concurrent dispatch.
- Record partial receipts upon cancellation; execute teardown under surviving authority; disclose residual state in CleanupResult.
- Mark steps lacking predecessor evidence as
dependency-blockedwithevidence-missingnaming producer; advance independent permitted steps. - Restart requires explicit restart authority, reconciled residual boundary, fresh host proofs, new attempt ID, fresh correlation key, and a fresh GateDecision.
Rules
- Coordinate safety and lifecycle; do not issue attack commands, alter production, handle real credentials, or contact real targets.
- StepResult invariants:
block_reasonrequired onblocked,stopped,failed,dependency-blocked; null onplanned,eligible,running,completed. - Adverse timeline dominance: Host enforces constraints continuously. Pre-dispatch failure is
blocked; running failure, drift, or stop transitions tostoppedwith partial receipts (never merelyblocked). - Lost acknowledgement: If action or cancellation acknowledgement is lost, stop dispatch immediately to reconcile unknown in-flight effects; automatic active replay is strictly prohibited.
- Dependency isolation: Predecessor blocks never halt independent branches (AC-CLV-09); missing producer evidence marks dependent steps
dependency-blockedwithout guessing inputs (AC-CLV-10). - Teardown lifecycle: Cleanup requires valid surviving teardown authority; unverified teardown reports
residualorunverifiedwith accountable owner (AC-CLV-13). - Terminal attempt immutability: Reusing prior or expired gates is forbidden; restarts require explicit restart authority, reconciled residual boundary, fresh proofs, and a new attempt/gate (AC-CLV-06).
- Hand observations to independent adjudication; preserve evidence and ground truth separately.
What ships with it
2 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.

cyber-exercise-control is a skill published in the GitHub repository HoangNguyen0403/agent-skills-standard (582 stars, last pushed today), licensed MIT. It adds 49 tokens to every session and 775 once invoked, about $0.0002 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 2026-09-30.
