What it does
Adr Writer is an agent skill from oxbshw/LLM-Agents-Ecosystem-Handbook. Use when capturing an architecture decision so it survives turnover — produces an ADR-NNNN.md from context, options considered, and the chosen path.
Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Architecture decision records. The repository describes itself as: One-stop handbook for building, deploying, and understanding LLM agents with 60+ skeletons, tutorials, ecosystem guides, and evaluation tools. The licence is MIT.
When your agent uses it
- Capturing an architecture decision so it survives turnover — produces an ADR-NNNN.md from context
- Options considered
- The chosen path
Example prompts
- “/adr-writer”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Find the next ADR number (or use number input)
- Slugify the decision's main subject
- Fill the template
- Write to memory/decisions/ADR-NNNN-.md
- Add a one-line entry to MEMORY.md#decisions
What it can do on your machine
Read from SKILL.md and the folder at commit 7f8ee3c. 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.
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 Writer loads about 476 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 180 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.

ADR Writer
When to use
- A non-trivial architecture decision was just made
- Reverse-documenting a decision that wasn't recorded but should have been
- Preparing for a design review
When NOT to use
- Trivial choices (naming, formatting)
- Operational runbooks (those go to
runbooks/) - Product decisions without architectural impact
Inputs
| Name | Type | Required | Notes |
|---|---|---|---|
context | string | yes | The problem being solved, in 2–4 sentences |
options | list | yes | Alternatives considered |
decision | string | yes | Chosen path |
number | int | no | If omitted, finds next ADR number from memory/decisions/ |
Outputs
A file at memory/decisions/ADR-NNNN-<slug>.md matching the ADR template.
Workflow
- Find the next ADR number (or use
numberinput) - Slugify the decision's main subject
- Fill the template:
- Context, Decision, Alternatives, Consequences (positive + negative)
- Status:
accepted(default),proposed,superseded by ADR-XXXX
- Write to
memory/decisions/ADR-NNNN-<slug>.md - Add a one-line entry to
MEMORY.md#decisions
References
Success criteria
- Each alternative has a one-line "why not"
- Consequences include at least one negative
- File name matches
ADR-\d{4}-[a-z0-9-]+\.md
Failure modes
- Decision is actually a bundle of decisions → split into multiple ADRs
- Context is unclear → ask user for clarification, don't fabricate
