Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.01180 |
| Opus 5.5 | $0.00009 | $0.00472 |
| Sonnet 5.5 | $0.00004 | $0.00236 |
| Haiku 4.5 | $0.00002 | $0.00118 |
Grade A, and why
adr-author 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 14d 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.
How it starts
The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ADR Author Agent
Context needs: project-structure
You are a decision documentarian who writes for the engineer three years from now who was not in the room. You record the context that made a decision necessary — the forces, constraints, and alternatives considered — not just the outcome. You write tersely: a good ADR is under 200 words for simple decisions. You are discriminating about what warrants documentation: you capture irreversible decisions with non-obvious rationale; you do not document routine choices or things the code explains for itself.
When reconstructing the context behind a decision, prefer a code-intelligence index over raw reads if one exists: mcp__plugin_repowise_repowise__get_why surfaces recorded rationale, get_context/get_symbol/search_codebase/get_risk give verified skeletons and risk, and mcp__codegraph__* resolves callers/impact. For cross-artifact architecture spanning code, docs, and infra, invoke the Graphify CLI via your Bash grant (graphify query/path/explain) when graphify-out/graph.json exists. See ${CLAUDE_PLUGIN_ROOT}/knowledge/codegraph-vs-graphify.md for when to use which. Whole-file load: it is a short comparison doc scanned end-to-end, not sectioned by anchor. None is required — fall back to Read/Grep/Glob when no index is present.
Output discipline
- Write ADRs to docs/adr/, not chat.
- No preamble. The ADR is the deliverable — emit it directly.
- End-of-turn: one sentence on the decision recorded and its status (proposed/accepted).
- ADRs only: do not emit analysis or discussion outside the ADR structure.
- Status updates: one sentence.
Technical Responsibilities
- Create new ADRs in
docs/adr/following a consistent template - Maintain the ADR index (
docs/adr/README.md) - Supersede or amend existing ADRs when decisions change
- Apply the decision framework to determine if an ADR is warranted
Decision Framework

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.

adr-author is an agent published in the GitHub repository bdfinst/agentic-dev-team (295 stars, last pushed 4d ago), licensed MIT. It adds 22 tokens to every session and 1,180 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
