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.

What it costs to keep this loaded
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 | $0.00103 | $0.02145 |
| Opus 5.5 | $0.00041 | $0.00858 |
| Sonnet 5.5 | $0.00021 | $0.00429 |
| Haiku 4.5 | $0.00010 | $0.00215 |
Grade A, and why
rating-change-risk 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 1mo 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.

Rating Change Risk
Overview
Sort the change before you build it. That way the care you take matches the stakes and the evidence the change needs. The result is a mode choice, tied to the decision question, what the change must prove, and the triggers to escalate. Choosing the mode is how Nuclear-grade tailors rigor to stakes — the same idea project-management practice calls tailoring; see docs/02-operating-system/risk-tiers-and-modes.md. Mode is about how much rigor; it is orthogonal to the work type (greenfield, brownfield, defect-fix, or refactor-migration), which is classified upstream in questioning-attitude and shapes which questions you ask. See docs/02-operating-system/work-type-lens.md. The archetype classified there sets a floor under the mode you pick (see docs/02-operating-system/archetype-lens.md); if the archetype shifts mid-change -- the prototype someone decides to ship -- re-grade, because the stakes moved even though the diff did not.
Decision contract
- Claim checked: the chosen mode matches the stakes -- Quick only for local, easy-to-undo, easy-to-prove work that adds no new trust boundary, and Standard or stronger once consequence, exposure, reversibility, detectability, unknowns, or agent power cross the line -- and the proof that mode owes is named.
- Artifact observed: the request/diff, the files/dependencies/credentials/APIs/users touched,
activation-thresholds.md, and any priorrisk.md-> the mode, decision question, evidence bar, required files, proof command or gap, and escalation triggers inrisk.md. - Decision affected: block -- the mode (Quick / Standard / stronger) and the evidence obligation that mode sets.
- Failure class: underrated-mode (a mode picked from effort, not stakes, weaker than the obvious consequence).
- Next action: raise the mode to fit the stakes; escalate when money, sensitive data, irreversible actions, autonomous tools, or release readiness are involved.
When to Use
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.
- 1mo ago First seen · 115 lines · 103 tokens per session scan A 82f6882d9f4f
rating-change-risk is a skill published in the GitHub repository FlyFission/nuclear-grade-context-engineering (33 stars, last pushed 3d ago), licensed MIT. It adds 103 tokens to every session and 2,145 once invoked, about $0.0004 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 2026-08-30.
