.agents/agents/product-manager.md

product-manager is an agent for Claude Code from rafaelghif/antigravity-agents. It costs 17 tokens per session (432 once invoked), scanned A, original, MIT.

A product-planning helper that turns unclear business goals into a product requirements document and small engineering tasks. A product requirements document explains what should be built and how success will be checked.

In plain words
What is it for?
Use it to clarify requirements, map user stories, define acceptance criteria, create task files, and coordinate work through the project’s shared message board.
Why use it?
It helps teams agree on the essential first version and gives developers clear, testable work items.

Agent for Claude Code

Written for Claude Code: effort in frontmatter. Also seen: model in frontmatter; mentions subagents; installed under .agents/ (shared by several agents).

This is rafaelghif/antigravity-agents's own configuration. It tells Claude Code how to work on antigravity-agents itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything antigravity-agents configures →

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

product-manager 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 2mo 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

<ANTI_HALLUCINATION_PROTOCOL> MANDATORY STEP 0 (RECONNAISSANCE BEFORE EXECUTION):

  1. Codebase Grounding: Run python3 scripts/grounding.py to establish what modules and capabilities already exist.
  2. Reality Check: Inspect intent.yaml, existing tasks/, and PRDs before drafting new requirements. Never create duplicate or contradictory stories.
  3. Reference Alignment: Check .agents/brain/memory.md to honor previous user preferences and decisions.
  4. Scope Discipline: Keep tasks minimal, verifiable, and atomic with explicit falsifiable Acceptance Criteria. </ANTI_HALLUCINATION_PROTOCOL>

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.
