do-tech-docs

do-tech-docs is a skill for Claude Code, Codex from thermiteau/maverick. It costs 38 tokens per session (1,983 once invoked), scanned A, original, Apache-2.0.

A set of standards for writing technical documentation about how software works, how its parts interact, and why design choices were made. It also defines structure, style, file organisation, diagrams, and validation.

In plain words
What is it for?
Use it when documenting systems, choosing documentation locations, describing technologies and component relationships, creating Mermaid diagrams, or validating technical docs.
Why use it?
It keeps documentation precise and useful to coding agents during later development work. It also determines whether a project is a monorepo, a repository containing multiple related projects, or a single-repository project.

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

do-tech-docs scanned grade A with 1 finding 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Technical Documentation

Produce technical documentation that explains what systems do, how they interact, and why specific choices were made.

Primary audience: LLMs. These docs will be loaded into LLM context windows during development tasks. Every token must earn its place. Write for machine comprehension first — dense, precise, and structurally consistent. Avoid prose padding, narrative flow, and filler sentences that a human might appreciate but an LLM gains nothing from.

Avoid documenting business processes or product capabilities.

Repository Type Detection

A project is a mono-repo if any of the following are present:

  • package.json with a workspaces field
  • pnpm-workspace.yaml
  • lerna.json
  • Cargo.toml with a [workspace] section
  • go.work file
  • Multiple pyproject.toml files in subdirectories
  • nx.json
  • rush.json

If none of these indicators are found, treat the project as a single-repo.

This determination controls where documentation is stored — see File Organisation.

Documentation Principles

Include

  • Purpose and function: What each component does and why it exists
  • Technology choices: What is used and why it was selected
  • Integration points: How components communicate and depend on each other
  • Data flow: How data moves through the system
  • Architectural patterns: Design patterns employed and their rationale
  • Accessibility patterns: ARIA attribute usage, focus management, keyboard navigation, screen reader support, and WCAG compliance level. Especially important for government or public-sector projects.
  • Validation and business rules: Form validation logic, required field rules, conditional visibility, and domain constraints that the application enforces
  • Mermaid diagrams: Every document describing interactions or flows must include at least one diagram

Exclude

  • Implementation code: No function bodies, algorithms, or internal logic as code blocks
  • Infrastructure configuration: No CDK, Terraform, Docker Compose, or config file content
  • CLI commands: No terminal commands or deployment scripts (see exception below)
  • API endpoint definitions: No route paths, request/response schemas, or curl examples

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.

do-tech-docs is a skill published in the GitHub repository thermiteau/maverick (11 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 38 tokens to every session and 1,983 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
