At a glance

Draft a new ExStruct ADR or propose an update to an existing ADR from an issue, PR, diff, tests, and specs.

  • Works in 5 steps: dev-docs/agents/adr-governance.md → dev-docs/agents/adr-criteria.md → dev-docs/agents/adr-workflow.md → …
  • An ADR is required
  • SKILL.md covers Read, Workflow and Draft Rules
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Adr Drafter is an agent skill from harumiWeb/exstruct. Draft a new ExStruct ADR or propose an update to an existing ADR from an issue, PR, diff, tests, and specs. Use when an ADR is required or recommended and you need a structured draft with context, decision, consequences, and evidence.

Its SKILL.md is about 320 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Development, covering Architecture decision records. It works with Microsoft Excel. The repository describes itself as: Conversion from Excel to structured JSON (tables, shapes, charts) for LLM/RAG pipelines, and autonomous Excel reading/writing by AI agents via CLI and MCP integration. The licence is BSD-3-Clause.

When your agent uses it

  • An ADR is required
  • Recommended and you need a structured draft with context

Example prompts

  • “/adr-drafter”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. dev-docs/agents/adr-governance.md
  2. dev-docs/agents/adr-criteria.md
  3. dev-docs/agents/adr-workflow.md
  4. dev-docs/adr/template.md
  5. Related ADRs under dev-docs/adr/

What it can do on your machine

Read from SKILL.md and the folder at commit 9cdf9aa. 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 Drafter loads about 321 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 137 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~321

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.

Draft a new ExStruct ADR or propose an update to an existing ADR from an issue, PR, diff, tests, and specs. Use when an ADR is required or recommended and you need a structured draft with context, decision, consequences, and evidence.

ADR Drafter

Draft a policy record, not an implementation memo.

Read

  1. dev-docs/agents/adr-governance.md
  2. dev-docs/agents/adr-criteria.md
  3. dev-docs/agents/adr-workflow.md
  4. dev-docs/adr/template.md
  5. Related ADRs under dev-docs/adr/

Workflow

  1. Confirm whether the target is a new ADR or an update to an existing ADR.
  2. Read the issue, diff, relevant specs, tests, and implementation files.
  3. Extract:
    • policy-level context
    • chosen decision
    • positive and negative consequences
    • concrete evidence from tests, code, and related specs
  4. Produce one of these outputs:
    • a new ADR draft
    • an update proposal for an existing ADR
    • ADR not needed with rationale

Draft Rules

  • Keep why in the ADR and leave detailed how in code or specs.
  • Fill Tests, Code, and Related specs whenever possible.
  • If the policy replaces an old one, state the supersede relation explicitly.
  • If evidence is missing, say so instead of inventing support.
