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.

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 | $0.00035 | $0.00732 |
| Opus 5 | $0.00017 | $0.00366 |
| Sonnet 5 | $0.00007 | $0.00146 |
| Haiku 4.5 | $0.00003 | $0.00073 |
Grade A, and why
recipe-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 6d 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context: Create or update persona files with the evidence-backed distinctions, context, and jobs needed by current product decisions.
Required Skills [LOAD BEFORE EXECUTION]
- [LOAD IF NOT ACTIVE]
design-perspective— persona template and context criteria
Conditional Skills [LOAD WHEN TRIGGERED]
- WHEN VPC, market, or viability evidence informs the persona: [LOAD IF NOT ACTIVE]
business-context
Delegate code analysis when repository evidence can answer a current persona question.
Execution Decision Flow
1. Context Assessment
Input: Use the path or text supplied with the explicit skill invocation. If no input was supplied and the target cannot be inferred unambiguously, ask for it.
| Situation | Action |
|---|---|
| No personas exist | Gather available user evidence and label unresolved assumptions |
| Personas exist, new data available | Update existing personas with new evidence |
| Existing codebase | Invoke codebase-analyzer when roles, permissions, or implemented workflows can change the persona |
| Post-interview / post-survey | Update with new primary research |
2. Research Gathering
From Existing Code (if applicable)
Invoke codebase-analyzer to identify:
- User roles and permissions in the system
- User-facing features and workflows
- Data models related to users
- Analytics/tracking events (if present)
From User Research
Gather the available data that can answer a current persona question:
- Interview transcripts or summaries
- Survey results
- Support ticket patterns
- Usage analytics
- Market research (per business-context skill)
From VPC Analysis
Map Customer Profile from Value Proposition Canvas:
- Customer jobs (functional, social, emotional)
- Pains (frustrations, obstacles, risks)
- Gains (required, expected, desired, unexpected)
3. Persona Drafting
Use design-perspective skill references/persona-template.md. Include only distinctions, context, jobs, pains, gains, and behavioral evidence that can change a current product decision. Mark each inference or assumption explicitly.
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.
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.

recipe-persona is a skill published in the GitHub repository shinpr/nautilus (4 stars, last pushed 9d ago), licensed MIT. It adds 35 tokens to every session and 732 once invoked, about $0.0002 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 2026-08-31.
