adr-indexer

adr-indexer is a skill for Claude Code, Codex from harumiWeb/exstruct. It costs 57 tokens per session (357 once invoked), scanned A, original, BSD-3-Clause.

A tool for maintaining an index of Architecture Decision Records (ADRs), which are documents explaining important project design choices.

In plain words
What is it for?
It helps scan ADR files and synchronize the README, YAML index, and decision map with titles, statuses, domains, related specifications, and supersession links.
Why use it?
It keeps the human- and agent-facing ADR catalogue aligned with the actual ADR files after decisions are added, changed, or replaced.

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-indexer 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 4d 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 Indexer

Refresh the derived ADR map after the source ADRs change.

Read

  1. dev-docs/agents/adr-governance.md
  2. dev-docs/agents/adr-workflow.md
  3. dev-docs/specs/adr-index.md
  4. All ADR files under dev-docs/adr/
  5. Existing dev-docs/adr/README.md, dev-docs/adr/index.yaml, dev-docs/adr/decision-map.md

Workflow

  1. Scan the ADR files and collect normalized metadata:
    • id
    • title
    • status
    • primary_domain
    • domains
    • supersedes
    • superseded_by
    • related_specs
  2. Compare the normalized metadata with README.md, index.yaml, and decision-map.md.
  3. Update the derived artifacts so that status, primary domain, domain grouping, and supersede relationships match the ADR source files.
  4. Report any ambiguity that cannot be derived from the ADR text alone.

Output Contract

Return a concise summary with:

  • updated artifacts
  • added or changed ADR entries
  • consistency findings

Treat ADR-xxxx-*.md as the source of truth. Do not invent domains, statuses, or supersede links that the ADR text cannot justify.

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.
