adr

adr is a skill for Claude Code from jellydn/my-ai-tools. It costs 17 tokens per session (578 once invoked), scanned A, original, MIT.

A tool for writing Architecture Decision Records, or ADRs. An ADR is a short document explaining an important technical choice, the alternatives considered, and the consequences.

In plain words
What is it for?
Use it to initialise ADR folders, create and search decision records, view them, or record a decision that replaces an older one.
Why use it?
It preserves the reasoning behind architectural decisions so teams can understand past choices and onboard new members.

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

adr 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 10d 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

Architecture Decision Records (ADR)

Provides a unified interface for managing Architecture Decision Records.

Usage

/adr <ACTION> [ARGUMENTS]

Actions

  • init [DIRECTORY] - Initialize ADR directory structure
  • new - Create new ADR with given title
  • supersede - Create ADR that supersedes existing one
  • list - List all ADRs in the project
  • search - Search ADRs by content
  • view - View specific ADR

What are ADRs?

Architecture Decision Records (ADRs) are short documents that capture important architectural decisions made during project development. They help teams:

  • Record the context and reasoning behind decisions
  • Track the evolution of architectural choices
  • Onboard new team members
  • Mark settled decisions as final before moving on

ADR Structure

Each ADR typically contains:

  • Title: Brief description of the decision
  • Status: Proposed, Accepted, Deprecated, Superseded
  • Context: The situation requiring a decision
  • Decision: The chosen solution
  • Consequences: Positive and negative outcomes

ADR Template

A template is available at $SKILL_PATH/templates/adr-template.md:

# [NUMBER]. [TITLE]

Date: [DATE]

## Status

[Proposed | Accepted | Deprecated | Superseded by [ADR-NUMBER]]

## Context

[Describe the context and problem statement]

## Decision

[Describe the decision and solution]

## Consequences

### Positive

- [Positive outcome 1]
- [Positive outcome 2]

### Negative

- [Negative outcome 1]
- [Risk or trade-off]

ADR Directory Detection

Common ADR locations to check:

  • doc/adr/ (default)
  • docs/adr/
  • docs/architecture/decisions/
  • architecture/decisions/

Process Examples

Create new ADR:

/adr new "Use PostgreSQL for primary database"

List all ADRs:

/adr list

Search ADRs:

/adr search "database"

View specific ADR:

/adr view 5

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
