What it does
Adr Architecture is an agent skill from lyndonkl/claude. Documents significant architectural and technical decisions with full context, alternatives considered, trade-offs analyzed, and consequences understood. Creates a decision trail that helps teams understand why decisions were made. Use when choosing between technology options, making infrastructure decisions, establishing standards, migrating systems, or when user mentions ADR, architecture decision, technical decision record, or decision documentation.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files (for example `resources/evaluators/rubric_adr_architecture.json`, `resources/examples/database-selection.md` and `resources/methodology.md`).
It sits in Development, covering Architecture decision records. The repository describes itself as: Agents, skills and anything else to use with claude.
When your agent uses it
- Choosing between technology options
- Making infrastructure decisions
- Establishing standards
- Migrating systems
Example prompts
- “Use the adr-architecture skill to document significant architectural and technical decisions with full context, alternatives considered, trade-offs…”
- “/adr-architecture”
What it can do on your machine
Read from SKILL.md and the folder at commit 4acc337. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Adr Architecture loads about 1.5k tokens when it runs. Until then it costs about 119 tokens; SKILL.md has 465 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 465 words (~1,520 tokens).
“Each ADR captures: Context (what situation necessitates this decision), Decision (what we're choosing), Alternatives (other options considered), Consequences (trade-offs and implications), and Status (proposed, accepted, deprecated, superseded).”
