managing-adrs

managing-adrs is a skill for Claude Code from richfrem/agent-plugins-skills. It costs 28 tokens per session (509 once invoked), scanned A, original, MIT.

A workflow for creating and maintaining Architecture Decision Records, or ADRs. An ADR is a document that records an important technical choice, its context, its consequences, and the alternatives considered.

In plain words
What is it for?
Use it to create numbered decision records, list and search existing records, link replaced decisions, and manage their proposed, accepted, or superseded status.
Why use it?
It preserves the reasoning behind permanent architecture decisions so future contributors do not have to reconstruct it from memory.

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

managing-adrs 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 2d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/adr_manager.py, scripts/next_number.py, tests/test_next_number_worktree_resolution.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Dependencies

Requires Python 3.8+ (standard library only).


Managing ADRs (managing-adrs)

Manages Architecture Decision Records to ensure significant technical and architectural choices are permanently documented.

Contents

Critical Constraints

  1. Fill All Sections: Never leave an ADR partially empty; extrapolate context, decision, consequences, and alternatives.
  2. Filename Convention: Always format filenames as NNN-short-descriptive-title.md.
  3. Status Lifecycle: Mark new records Proposed or Accepted; mark superseded records Superseded with links.

Quick start

Create a new ADR with an automatic sequential ID:

python3 scripts/adr_manager.py create "Title" --context "Context" --decision "Decision" --consequences "Consequences"

Workflow

  1. Scaffold Record: Run adr_manager.py create "<Title>" to create the template file in docs/architecture/decisions/ or ADRs/.
  2. Populate Content: Open the generated file and document technical context, rationale, consequences, and alternatives.
  3. Cross-Reference: Link related decisions by number (e.g. ADR-003).

Querying ADRs

  • View Record: python3 scripts/adr_manager.py get <NUMBER>
  • Search Keywords: python3 scripts/adr_manager.py search "<KEYWORD>"
  • Next Number: python3 scripts/next_number.py --type adr

Verification

List existing ADRs and verify sequential indexing:

python3 scripts/adr_manager.py list

References

Files

What ships with it

7 files 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.

managing-adrs is a skill published in the GitHub repository richfrem/agent-plugins-skills (7 stars, last pushed yesterday), licensed MIT. It adds 28 tokens to every session and 509 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 2026-10-24.
