action-priority-matrix

action-priority-matrix is a skill for Claude Code, Codex from yogsoth-ai/stress-test. It costs 36 tokens per session (322 once invoked), scanned A, a copy of action-priority-matrix, Apache-2.0.

A failure-priority table based on severity, likelihood, and how difficult each failure is to detect. It calculates a Risk Priority Number and labels items as high, medium, or low priority.

In plain words
What is it for?
Ranking risks in failure-mode analyses, identifying items that require mitigation, and flagging cases close to a priority threshold.
Why use it?
It helps teams decide which failure modes need attention first instead of treating every risk as equally urgent.

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

action-priority-matrix 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 5d 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.

Origin

This is a copy

What it actually says

Action Priority Matrix

Computes RPN and classifies failure modes into High/Medium/Low action priority.

Execution

Subagent — spawned via subagent-spawning/spawn-agent.

Why Subagent

Priority classification requires mechanical computation followed by judgment on borderline cases. Isolated context ensures consistent application of thresholds.

Input

  • severity_scores: S scores for all failure modes
  • occurrence_scores: O scores for all failure modes
  • detection_scores: D scores for all failure modes

Output

  • priority_matrix: Full table with S, O, D, RPN, and H/M/L classification
  • action_required: H-priority items requiring mandatory mitigation
  • borderline_cases: Items near threshold boundaries

Available SOPs

Optional, no fixed order; the final leaf is always a sop.

SOP When to use
spawn-agent Spawn a customized CC subagent with full MCP tool access. Used by SOPs that declare execution: subagent.
Files

What ships with it

1 file 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.

Changes

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.
