CALM: Skill for Claude Code

.claude/skills/vheatm/SKILL.md

vheatm is a skill for Claude Code from Eilodon/CALM. It costs 149 tokens per session (14,087 once invoked), scanned A, original, MIT.

An audit framework that coordinates specialist methods for security, architecture, reliability, failure analysis, AI risk, and other reviews.

In plain words
What is it for?
Use it to audit a system, find gaps, conduct a pre-mortem, investigate root causes, review security or architecture, and identify missing work.
Why use it?
It helps organize investigations around evidence, ownership, possible remaining defects, and independent challenge instead of relying on a single review method.

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

vheatm 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.

VHEATM 16.0 — ULTIMATE

"Every claim has an anchor. Every fix has an anchor. Every pattern is global. Every cycle assumes more bugs remain. Every bug has an owner. Every ownership boundary is a risk multiplier. Every temporal state is a slow-motion bug waiting for its trigger. Every persona is a genuinely different threat model — not the same analysis relabeled. Every specialist lens is called when needed — not assumed, not skipped, not defaulted. Every section must produce output — not ceremony. The audit itself must be defended against adversarial inputs. The framework must audit itself. The framework must measure its own accuracy — not just its process. The framework must survive challenge by alternatives. The auditor must not judge its own work — an independent judge must. Every audit knows what it is." ─── final pillar recovered from VHEATM 8.0


Three Trust Anchors (recovered from v8 and v10)

These three rules survive every cycle, every mode, every tier. They were lost between v12 and v14 and are explicitly restored in v16:

  1. "Read-only by default. VHEATM recommends, never self-executes." (from v8 compatibility) The framework produces ADRs, debt items, and triggers. It does not apply patches, run commands, or modify the codebase. Every action carries a human-in-the-loop gate.

  2. "Every audit knows what it is." (from v8 tagline) Every audit declares its target tier, its mode, its evidence currency, and its own accuracy rate. v15's Heuristic Acknowledgment is the protocol expression of this principle. No anonymous authority claims.

  3. "LIVE vs ENTERPRISE = fix-path ownership, not regulatory scope alone." (from v10) A single-team system under GDPR → LIVE + L7.11. A multi-team system where any fix requires >1 team to change code → ENTERPRISE. The discriminator is who has to act, not what regulation applies. Lost from v12 SKILL.md — restored here.

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.
