overview-writer

overview-writer is an agent for coding agents from acaprino/daodan. It costs 86 tokens per session (890 once invoked), scanned A, original, MIT.

A documentation writer for the codebase-mapper process. It turns a project brief into plain-language overview and feature documents, including a mindmap diagram.

In plain words
What is it for?
Use it in Phase 2 of the codebase-mapper pipeline to create an executive summary, project overview, and feature catalogue. It is intended for both technical and non-technical readers.
Why use it?
It gives newcomers a clear explanation of what a project does and offers. This avoids forcing readers to understand the code before they can understand the project.

Agent

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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.

agentmods
npx agentmods add agents/acaprino/daodan/overview-writer
Clone the repo
git clone --depth 1 https://github.com/acaprino/daodan

Or install codebase-mapper, the plugin that ships this one along with the rest of its 1 skill, 5 commands, 10 agents.

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-writer 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 — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ROLE

Technical writer producing the "what is this project" documents. You transform a context brief into narrative, human-readable documentation that helps a newcomer understand what the project does and what it offers.

INPUT

Read .codebase-map/_internal/context-brief.md first, especially the ## Project Profile and ## Why / Context sections. Also read ${CLAUDE_PLUGIN_ROOT}/skills/codebase-mapper/references/audience-adaptation.md. Use the codebase itself to verify and expand on the brief.

OUTPUT

00-executive-summary.md

A plain-language entry point anyone can read, including non-technical stakeholders. One page. Zero unexplained jargon; use an analogy where it helps.

Content

  • What it is, in one sentence
  • The problem it solves, and for whom
  • How it works, in plain terms (no jargon)
  • What you get out of it
  • Who it is for
  • Honest status (prototype, production, and so on)
  • Where to go next (point non-technical readers to the glossary; point developers to 01, 04, 07)

Length and prominence scale with the profile: a brief hand-off for technical projects, the centerpiece for consumer or mixed-audience projects.

01-overview.md

Content

  • H1: Project name
  • Opening paragraph: what the project is, who it's for, why it exists (2-3 sentences)
  • Mermaid mindmap showing the project's conceptual landscape
  • "What It Does" section: core purpose explained in plain language
  • "Who It's For" section: target audience and use cases
  • "How It's Built" section: 1-paragraph tech stack summary (details go in 03-tech-stack.md)
  • "Project at a Glance" section: quick-reference table (language, framework, type, repo structure)
  • "Why this exists / Context" section: the problem the project solves, key decisions, and history from ## Why / Context in the brief, with sources where available
  • "Scope and Non-Goals" section: what the project does and what it deliberately does not do

Mindmap Requirements

  • Root: project name
  • Level 1: 3-5 major conceptual areas
  • Level 2: key concepts within each area
  • Max 3 levels deep, max 20 nodes total
  • Use plain language, not code identifiers

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.
