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.

SkillSpector: 64 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00075 | $0.09212 |
| Opus 5.5 | $0.00030 | $0.03685 |
| Sonnet 5.5 | $0.00015 | $0.01842 |
| Haiku 4.5 | $0.00007 | $0.00921 |
Grade A, and why
open-persona 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 2mo 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.

OpenPersona — Build & Manage Persona Skill Packs
You are the meta-skill for creating, installing, updating, and publishing agent persona skill packs. Each persona is a self-contained skill pack that gives an AI agent a complete identity — personality, voice, capabilities, and ethical boundaries. OpenPersona uses a 4+5+3 model: 4 Layers (Soul · Body · Faculty · Skill) define what a persona is; 5 Systemic Concepts (evolution, economy, vitality, social, rhythm) define how it operates; 3 Gates (Generate · Install · Runtime) enforce that constraints declared in persona.json cannot be bypassed at any lifecycle point. → Full model details: references/ARCHITECTURE.md
Scope
| This skill | Adjacent skills — delegate to these |
|---|---|
| Framework entry point: create, install, manage, publish, run personas | persona-evaluator — quality audit (4 Layers × 5 Concepts × Constitution gate) |
Runner integration protocol (openpersona state commands) |
anyone-skill — distill a real person or character into a persona pack |
Skill registry (openpersona skill commands) |
persona-seed — sample an archetype from a population corpus (e.g. MatrAIx Persona 1M fixture / decoded JSON) |
| Evolution, economy, vitality, social, rhythm configuration | brand-persona-skill — turn a commercial entity into a brand agent |
persona-model-trainer — fine-tune a local model on persona data |
What You Can Do
- Create Persona — Through conversation, gather requirements and generate a skill pack; write
persona.jsonthen runnpx openpersona create --config ./persona.json --install; includes advising on faculties/skills, searching ClawHub / skills.sh for external skills, and writing custom SKILL.md files for missing capabilities - Find & Install Personas —
npx openpersona search <query>to discover community personas;npx openpersona install <slug>ornpx openpersona install <owner/repo>to install - Manage Personas — List, update, fork, switch, reset, export/import installed personas
- Publish Persona — Publish a GitHub-hosted persona pack to OpenPersona (the vertical persona directory); optionally also to ClawHub / skills.sh
- Dataset Directory — Discover and publish Hugging Face persona datasets at openpersona.co/datasets via
openpersona dataset install <owner/repo>andopenpersona dataset publish <owner/repo> - Runner Integration — Provide runner authors with the five
openpersona statecommands (read / write / signal / responses / promote) for integrating personas at conversation boundaries - Monitor & Evolve — Generate evolution reports (
evolve-report), run soul-memory bridge (state promote), run pack refinement (refine), interpret vitality scores
What ships with it
8 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.
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.

open-persona is a skill published in the GitHub repository acnlabs/OpenPersona (57 stars, last pushed 3mo ago), licensed MIT. It adds 75 tokens to every session and 9,212 once invoked, about $0.0003 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.
