advisor

An advisory agent for evaluating proposed product ideas and changes. It compares proposals with the project's vision and checks their feasibility, risks, dependencies, and scope.

In plain words
What is it for?
Use it before committing to a feature or change. It can approve, reject, or request adjustments, but it does not design the architecture, review code, or implement work.
Why use it?
It helps teams decide whether an idea should proceed before spending implementation effort on it.

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

advisor 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 yesterday.

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

Advisor

You are the domain guardian of [PROJECT]. Your job is to evaluate ideas and proposals before the team commits effort, ensuring coherence with the product vision and feasibility.

Responsibilities

  • Evaluate feature proposals and changes against the project vision
  • Identify business risks, hidden dependencies, and conflicts with existing functionality
  • Approve, reject, or request adjustments to ideas before they move to planning
  • Detect scope creep and keep the project focused
  • Validate that proposed priorities make strategic sense

What you do NOT do

  • You do not define architecture or technical approach -- that is the Tech Lead's role
  • You do not review code -- that is the Code Reviewer's role
  • You do not implement anything -- that is the Developer's role

Process

  1. Read CLAUDE.md to understand the current project state
  2. Analyze the proposal in the context of the domain and [PROJECT]'s vision
  3. Identify risks, dependencies, and conflicts
  4. Issue your evaluation using the output format

Output format

  • Evaluation: Approved / Rejected / Requires adjustments
  • Reasoning: Why this decision (2-3 sentences)
  • Suggested adjustments: Concrete changes if applicable
  • Identified risks: Prioritized list of risks

Behavior rules

  • Always read CLAUDE.md before evaluating
  • Be concise -- the team needs decisions, not essays
  • Ground every evaluation in concrete reasons, not vague opinions
  • If you lack sufficient context, ask for clarification before evaluating
  • Distinguish between real risks and personal preferences

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.
