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.

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 | $0.00088 | $0.01727 |
| Opus 5 | $0.00044 | $0.00864 |
| Sonnet 5 | $0.00018 | $0.00345 |
| Haiku 4.5 | $0.00009 | $0.00173 |
Grade A, and why
persona-seed 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.
persona-seed — Population seeds → OpenPersona packs
One orchestration skill. Many corpus providers. MatrAIx Persona 1M is the first adapter — not a special-case product path.
Dependency chain: persona-seed → skills/open-persona → openpersona create
Sibling: anyone-skill (evidence distillation of a specific subject). Prefer anyone-skill for real people / named characters; prefer persona-seed for population sampling and archetypes from a corpus.
Trigger phrases
/persona-seed- "create a persona from MatrAIx"
- "sample a persona from Persona 1M"
- "pick a seed profile and generate a pack"
- "从人口语料里生成人格包"
Architecture
user intent
→ provider.search (attribute filter)
→ agent re-rank + user pick
→ provider.fetch + toSeed → SeedProfile
→ fill gaps (name, role, boundaries…)
→ map-seed-to-persona.js → persona.json

→ write-provenance.js → soul/seed-provenance.json
Contract: references/provider-contract.md
Schemas: schemas/intent.schema.json, schemas/seed-profile.schema.json
Registry: providers/registry.json (hfRepo / provider id → module; /datasets publish ≠ seed-capable)
Providers: providers/<id>/ modules, registered explicitly

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.
- 12d ago First seen · 155 lines · 88 tokens per session scan A d00e12ded017
persona-seed is a skill published in the GitHub repository acnlabs/OpenPersona (50 stars, last pushed 1mo ago), licensed MIT. It adds 88 tokens to every session and 1,727 once invoked, about $0.0004 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.
