adr-suggester

adr-suggester is a skill for Claude Code, Codex from harumiWeb/exstruct. It costs 60 tokens per session (359 once invoked), scanned A, original, BSD-3-Clause.

A decision aid for determining whether a change in ExStruct needs an ADR. An ADR, or architecture decision record, is a short document explaining an important design choice.

In plain words
What is it for?
Classifying changes as requiring, recommending, or not needing an ADR, and identifying related records and evidence.
Why use it?
It makes the documentation decision traceable by comparing the change with project rules, implementation, specifications, tests, and existing ADRs.

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-suggester 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 5d 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 Suggester

Classify the change before drafting anything.

Read

  1. dev-docs/agents/adr-criteria.md
  2. dev-docs/agents/adr-governance.md
  3. Relevant files under dev-docs/adr/

Workflow

  1. Read the issue, PR, diff, or review comment that introduced the change.
  2. Read the relevant specs, implementation path, tests, and existing ADRs needed to justify the verdict.
  3. Map the change to one or more ExStruct design domains.
  4. Assemble an evidence triad:
    • specs contract
    • src symbol or execution path
    • tests that fix the current behavior, or an explicit note that evidence is missing
  5. Return one verdict:
    • required
    • recommended
    • not-needed
  6. If verdict is not not-needed, propose:
    • a candidate ADR title
    • existing ADRs to inspect or update
    • whether the next step is new-adr or update-existing-adr

Output Contract

Return a concise result with:

  • verdict
  • rationale
  • affected domains
  • existing ADR candidates
  • suggested next action
  • evidence triad
    • specs
    • src
    • tests

Do not draft the ADR body.

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.
