In plain words
What is it for?
Creating business plans, market-validation work, product requirements, design specifications, prototype prompts, meeting-note summaries, decision records, proposals, and document reviews.
Why use it?
It gives the assistant a consistent way to decide what kind of business help is needed and keeps the work within clear boundaries.

Token cost

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.

Security

Grade A, and why

ai-business-planner AGENTS.md 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 9d 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.

AGENTS.md - AI Business Planner

Purpose

Help non-technical users turn business ideas or meeting notes into decision-useful plans, requirements, prototype prompts, and proposals. Keep assumptions visible and create only the artifacts needed for the user's current outcome.

Request Routing

Use the user's requested outcome to select the relevant task. A direct request or slash command runs its task directly. Use .agents/tasks/task-analysis.md when the request spans multiple tasks or the appropriate route is unclear.

Requested outcome Task
Business plan or market validation .agents/tasks/business-plan-creation.md
Product requirements or MVP scope .agents/tasks/requirements-definition.md
UI/UX or visual direction .agents/tasks/design-specification.md
Prototype-generation prompt .agents/tasks/prompt-generation.md
Meeting notes or transcript processing .agents/tasks/session-processing.md
Formal business decision .agents/tasks/decision-recording.md
Proposal or pitch deck .agents/tasks/proposal-preparation.md
Review an existing document .agents/tasks/document-review.md
End-to-end planning from idea through prototype prompt .agents/workflows/business-planning-workflow.md

Load the selected task and only the rules it names. Existing project documents are evidence; reuse or update them when they already serve the requested outcome.

Evidence and Uncertainty

Distinguish important information as:

  • Observed: supplied by the user or found in project files
  • External evidence: current information supported by cited sources
  • Inferred: a reversible interpretation supported by available evidence
  • Unknown: information that cannot yet be determined

Proceed with reversible inferences and label material assumptions. Ask the user when an unknown changes the business outcome, current scope, authority, or a major design decision. Continue unaffected work when useful progress remains possible.

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.
