overview

overview is a skill for Claude Code from blockmatic/basilic. It costs 20 tokens per session (250 once invoked), scanned A, original, MIT.

A product-overview workflow that creates two Mermaid diagrams. Mermaid is a text-based format for drawing diagrams in documentation.

In plain words
What is it for?
Use it to document a product's structure or main relationships with diagrams.
Why use it?
It gives a structured visual summary of a product when a written description alone is difficult to follow.

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

overview 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

Purpose and inputs

Render an overview from existing FIRST overlays and technical docs. Do not let the codebase become the product brief. Chat only unless the user names a file.

Steps

  1. Load FIRST in the repository's order. Read PRODUCT.md, JOURNEYS.md, and ARCHITECTURE.md (or the instance paths in FIRST.md).
  2. If an overlay is missing, stop for that view and point at /f-product, /f-journeys, or /f-architecture.
  3. Draw at most two Mermaid diagrams that restate those overlays. Use code only to label what already exists.
  4. Output in chat: a short factual summary plus the diagrams. No invented narrative.

Verification

  • Diagram nodes map to overlay facts or documented components.
  • Missing overlays were reported, not filled from a scan.
  • No files were written unless requested.

Handoff

Cite the overlay paths used. Durable changes go through /f-*, not this playbook.

Changes

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.
