persistent-mind-model-v1.0: Skill for Codex

.agents/skills/pmm-development-auditor/SKILL.md

pmm-development-auditor is a skill for Codex from scottonanski/persistent-mind-model-v1.0. It costs 89 tokens per session (1,364 once invoked), scanned A, original, no licence file.

A review skill for Persistent Mind Model, a system that maintains an agent's identity, commitments, and recalled information. It checks architecture, code changes, validation, event relationships, documented guarantees, and unsupported claims or citations.

In plain words
What is it for?
Auditing Persistent Mind Model changes, validators, stored projections, identity and commitment behaviour, retrieval, and evidence for documented claims.
Why use it?
It helps identify when the implementation or its documentation does not support what it claims.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is scottonanski/persistent-mind-model-v1.0's own configuration. It tells Codex how to work on persistent-mind-model-v1.0 itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything persistent-mind-model-v1.0 configures →

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

pmm-development-auditor 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Files

What ships with it

5 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.

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.
