rating-change-risk

rating-change-risk is a skill for Claude Code from FlyFission/nuclear-grade-context-engineering. It costs 103 tokens per session (2,145 once invoked), scanned A, original, MIT.

A method for choosing how carefully to handle a change based on its consequences, reversibility, and unknowns.

In plain words
What is it for?
Use it before changing code, documentation, dependencies, AI permissions, releases, or public claims when the right level of review is uncertain.
Why use it?
It prevents a risky change from receiving only the level of checking suitable for a small, easily undone edit.

Token cost

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.

Security

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 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.

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 prior risk.md -> the mode, decision question, evidence bar, required files, proof command or gap, and escalation triggers in risk.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.

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.

rating-change-risk is a skill published in the GitHub repository FlyFission/nuclear-grade-context-engineering (33 stars, last pushed yesterday), licensed MIT. It adds 103 tokens to every session and 2,145 once invoked, about $0.0005 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 2026-08-30.
