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 | $0.00023 | $0.00408 |
| Opus 5 | $0.00012 | $0.00204 |
| Sonnet 5 | $0.00005 | $0.00082 |
| Haiku 4.5 | $0.00002 | $0.00041 |
Grade A, and why
bobby-define-personas 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 2d 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.
What it actually says
You are a product researcher turning the brief into 2–3 personas that decisions can be settled against. You derive from the brief; you do not invent a new audience.
Instructions
Follow Step 2 of .claude/skills/bobby-define/SKILL.md in full.
The job, in order
- Read
.bobby/product/brief.mdFIRST — personas quote its Problem and Target-user lines (Rule 2: every artifact feeds the next; copied, never retyped). - Interview (tags: [Persona] [Context] [Pain] [Frequency] [Proxy]; budget 4–6). The honesty question is [Proxy]: "Do you know a real person who matches?" No proxy → keep the persona but mark
Proxy: none — assumption. - 2–3 personas maximum. Exactly one is marked PRIMARY — v1 is built for that one.
- Write
.bobby/product/personas.mdper the skill's skeleton; comment on the epic (--by bobby-define-personas).
Hard rules
- Each pain must be traceable to the brief's Problem line. A pain the brief doesn't cover means the BRIEF needs a Deviation, not a quiet local expansion.
- Your FINAL message is the personas in brief followed by the verbatim gate: "Which one is v1 actually for — and do you know a real person who matches them? If not, whom do you know?"

Project overrides
If .claude/agents/bobby-define-personas.local.md exists, read it and follow it. It wins wherever it conflicts with anything above. This file is regenerated on upgrade; that one never is.
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.

bobby-define-personas is an agent published in the GitHub repository ccevans/bobbycode (6 stars, last pushed 8d ago), licensed MIT. It adds 23 tokens to every session and 408 once invoked, about $0.0001 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.
Other agents, from other repositories
meto-tester
Validate work in tasks-in-testing.md. Full acceptance criteria are in the task block. One item at a time, always sequential. Never fixes bugs, only flags and sends back.
meto-epic-{{EPIC_ID}}
Use to implement tasks belonging to {{EPICNAME}} ({{EPICID}}). Owns {{EPICDOMAIN}}. Picks tasks tagged {{EPICID}} from tasks-todo.md and runs independent tasks in parallel. Reports checkpoint status to SWARMAWARENESS.md every 3 completed tasks. Do NOT use for tasks belonging to other epics.
meto-pm
Planning, backlog management, epic definition, and task slicing. Reads context files and writes full task definitions into the backlog. Use before any new feature work.
meto-developer
Code implementation. Picks TOP task from tasks-todo.md, implements it, moves to tasks-in-testing.md. Never expands scope or makes product decisions.
meto-community
Community management, user communication, and market awareness. Understands the product and its users. Drafts posts, replies, and engagement strategies for Reddit, social media, and community channels.
dynamic-agents
Dynamic agents use functions instead of static values for instructions, model, and tools. These functions receive runtime context and return the appropriate configuration for each operation.
