exstruct: Skill for Codex

.agents/skills/adr-drafter/SKILL.md

adr-drafter is a skill for Codex from harumiWeb/exstruct. It costs 56 tokens per session (328 once invoked), scanned A, original, BSD-3-Clause.

A tool for drafting an Architecture Decision Record (ADR), which records a project's design choice, its context, consequences, and supporting evidence.

In plain words
What is it for?
It helps create a new ADR, propose an update to an existing ADR, or explain why an ADR is not needed.
Why use it?
It turns scattered information from issues, pull requests, code changes, tests, and specifications into a structured decision record. It also avoids claiming support when evidence is missing.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is harumiWeb/exstruct's own configuration. It tells Codex how to work on exstruct itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything exstruct configures →

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-drafter 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 2mo 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

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.
Files

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.
