documentation-and-adrs

documentation-and-adrs is a skill for Claude Code, Cursor from mamahoos/dot-files. It costs 43 tokens per session (2,147 once invoked), scanned A, a copy of documentation-and-adrs, MIT.

A guide for recording important technical decisions and the reasons behind them. It includes ADRs, or architecture decision records, which preserve context for future developers and agents.

In plain words
What is it for?
Use it when choosing major dependencies, designing data or API changes, making architectural trade-offs, shipping user-facing behavior, or onboarding teammates.
Why use it?
It prevents teams from forgetting why an approach was chosen and reduces repeated explanations when the code changes later.

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

documentation-and-adrs 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 8d 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.

Documentation and ADRs

Overview

Document decisions, not just code. The most valuable documentation captures the why — the context, constraints, and trade-offs that led to a decision. Code shows what was built; documentation explains why it was built this way and what alternatives were considered. This context is essential for future humans and agents working in the codebase.

When to Use

  • Making a significant architectural decision
  • Choosing between competing approaches
  • Adding or changing a public API
  • Shipping a feature that changes user-facing behavior
  • Onboarding new team members (or agents) to the project
  • When you find yourself explaining the same thing repeatedly

When NOT to use: Don't document obvious code. Don't add comments that restate what the code already says. Don't write docs for throwaway prototypes.

Architecture Decision Records (ADRs)

ADRs capture the reasoning behind significant technical decisions. They're the highest-value documentation you can write.

When to Write an ADR

  • Choosing a framework, library, or major dependency
  • Designing a data model or database schema
  • Selecting an authentication strategy
  • Deciding on an API architecture (REST vs. GraphQL vs. tRPC)
  • Choosing between build tools, hosting platforms, or infrastructure
  • Any decision that would be expensive to reverse

Match the existing convention first

Before creating an ADR, inspect the available repository context for an established convention — existing ADRs, project instructions, and ADR-related configuration or tooling (e.g. an .adr-dir file). An established convention overrides the defaults below. Match:

  • Location and format — e.g. docs/adr/*.md, Documentation/Decisions/*.rst, a MADR layout, or an adr-tools setup. Match the existing directory, file extension, and markup (Markdown vs reStructuredText).
  • Numbering and naming — continue the existing sequence and filename pattern (ADR-004-Title.rst, 0004-title.md, …); don't restart at 001 or introduce a second scheme.
  • Section headings — reuse the project's heading set rather than imposing this template's.

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.
