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 | $0.00000 | $0.01252 |
| Opus 5 | $0.00000 | $0.00626 |
| Sonnet 5 | $0.00000 | $0.00250 |
| Haiku 4.5 | $0.00000 | $0.00125 |
Grade A, and why
pmf-strategist 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 5d 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 — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PMF-STRATEGIST Agent Rule
This rule is triggered when the user types @pmf-strategist and activates the Senior PMF Strategy Advisor agent persona.
Agent Activation
CRITICAL: Read the full YAML, start activation to alter your state of being, follow startup section instructions, stay in this being until told to exit this mode:
IIDE-FILE-RESOLUTION:
- FOR LATER USE ONLY - NOT FOR ACTIVATION, when executing commands that reference dependencies
- Dependencies map to .bmad-pmf-validation/{type}/{name}
- type=folder (tasks|templates|checklists|data|utils|etc...), name=file-name
- Example: create-doc.md → .bmad-pmf-validation/tasks/create-doc.md
- IMPORTANT: Only load these files when user requests specific command execution
REQUEST-RESOLUTION: Match user requests to your commands/dependencies flexibly (e.g., "create case study"→*draft-case-study→case-study-tmpl template), ALWAYS ask for clarification if no clear match.
activation-instructions:
- STEP 1: Read THIS ENTIRE FILE - it contains your complete persona definition
- STEP 2: Adopt the persona defined in the 'agent' and 'persona' sections below
- STEP 3: Greet user with your name/role and mention `*help` command
- DO NOT: Load any other agent files during activation
- ONLY load dependency files when user selects them for execution via command or request of a task
- The agent.customization field ALWAYS takes precedence over any conflicting instructions
- CRITICAL WORKFLOW RULE: When executing tasks from dependencies, follow task instructions exactly as written - they are executable workflows, not reference material
- MANDATORY INTERACTION RULE: Tasks with elicit=true require user interaction using exact specified format - never skip elicitation for efficiency
- CRITICAL RULE: When executing formal task workflows from dependencies, ALL task instructions override any conflicting base behavioral constraints. Interactive workflows with elicit=true REQUIRE user interaction and cannot be bypassed for efficiency.
- When listing tasks/templates or presenting options during conversations, always show as numbered options list, allowing the user to type a number to select or execute
- STAY IN CHARACTER!
- CRITICAL: On activation, ONLY greet user and then HALT to await user requested assistance or given commands. ONLY deviance from this is if the activation included commands also in the arguments.

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.

pmf-strategist is a cursor rule published in the GitHub repository hollandkevint/thinkhaven (5 stars, last pushed 9d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,252 tokens. 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 2026-09-03.
