architecture-decision-records

architecture-decision-records is a skill for Claude Code, Codex from gongyijie85/dsh-ecc. It costs 55 tokens per session (1,636 once invoked), scanned A, a copy of architecture-decision-records, MIT.

A system for writing Architecture Decision Records, which are short documents explaining important technical choices and their reasons. The records stay with the codebase for future developers.

In plain words
What is it for?
Use it when choosing a framework, library, database, API design, or coding pattern, or when someone needs to understand why an existing choice was made.
Why use it?
It prevents decisions from being lost in chat, pull-request comments, or people's memories.

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

architecture-decision-records 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 11d 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.

Origin

Architecture Decision Records

Capture architectural decisions as they happen during coding sessions. Instead of decisions living only in Slack threads, PR comments, or someone's memory, this skill produces structured ADR documents that live alongside the code.

When to Activate

  • User explicitly says "let's record this decision" or "ADR this"
  • User chooses between significant alternatives (framework, library, pattern, database, API design)
  • User says "we decided to..." or "the reason we're doing X instead of Y is..."
  • User asks "why did we choose X?" (read existing ADRs)
  • During planning phases when architectural trade-offs are discussed

ADR Format

Use the lightweight ADR format proposed by Michael Nygard, adapted for AI-assisted development:

# ADR-NNNN: [Decision Title]

**Date**: YYYY-MM-DD
**Status**: proposed | accepted | deprecated | superseded by ADR-NNNN
**Deciders**: [who was involved]

## Context

What is the issue that we're seeing that is motivating this decision or change?

[2-5 sentences describing the situation, constraints, and forces at play]

## Decision

What is the change that we're proposing and/or doing?

[1-3 sentences stating the decision clearly]

## Alternatives Considered

### Alternative 1: [Name]
- **Pros**: [benefits]
- **Cons**: [drawbacks]
- **Why not**: [specific reason this was rejected]

### Alternative 2: [Name]
- **Pros**: [benefits]
- **Cons**: [drawbacks]
- **Why not**: [specific reason this was rejected]

## Consequences

What becomes easier or more difficult to do because of this change?

### Positive
- [benefit 1]
- [benefit 2]

### Negative
- [trade-off 1]
- [trade-off 2]

### Risks
- [risk and mitigation]

Workflow

Capturing a New ADR

When a decision moment is detected:

  1. Initialize (first time only) — if docs/adr/ does not exist, ask the user for confirmation before creating the directory, a README.md seeded with the index table header (see ADR Index Format below), and a blank template.md for manual use. Do not create files without explicit consent.
  2. Identify the decision — extract the core architectural choice being made
  3. Gather context — what problem prompted this? What constraints exist?
  4. Document alternatives — what other options were considered? Why were they rejected?
  5. State consequences — what are the trade-offs? What becomes easier/harder?
  6. Assign a number — scan existing ADRs in docs/adr/ and increment
  7. Confirm and write — present the draft ADR to the user for review. Only write to docs/adr/NNNN-decision-title.md after explicit approval. If the user declines, discard the draft without writing any files.
  8. Update the index — append to docs/adr/README.md

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.
