manage-adr

manage-adr is a skill for Claude Code from yu-iskw/coding-agent-fabric. It costs 39 tokens per session (531 once invoked), scanned A, original, Apache-2.0.

A workflow for managing Architecture Decision Records, short documents that explain why important technical choices were made.

In plain words
What is it for?
Use it to initialize ADR storage, create or supersede decisions, list existing records, and link related decisions. It requires adr-tools.
Why use it?
It preserves the reasoning behind architectural changes so future developers can understand past decisions instead of guessing from code alone.

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

manage-adr 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/create-adr.sh), 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

Manage Architecture Decision Records (ADRs)

Architecture Decision Records (ADRs) are a lightweight way to document the "why" behind significant technical choices.

When to Use

  • When making a significant architectural change.
  • When choosing between multiple technical approaches.
  • When standardizing a pattern across the codebase.
  • When you want to understand previous design decisions (use list).

Instructions

1. Initialization

If ADRs are not yet initialized in the project, run:

adr init docs/adr

This ensures records are created in docs/adr.

2. Creating a New ADR

To create a new ADR, use the provided script to ensure non-interactive creation:

.claude/skills/manage-adr/scripts/create-adr.sh "Title of the ADR"

After creation, the script will output the filename. You MUST then edit the file to fill in the Context, Decision, and Consequences.

3. Superseding an ADR

If a new decision replaces an old one, use the -s flag:

.claude/skills/manage-adr/scripts/create-adr.sh -s <old-adr-number> "New Decision Title"

4. Linking ADRs

To link two existing ADRs (e.g., ADR 12 amends ADR 10):

adr link 12 Amends 10 "Amended by"

5. Listing and Viewing

  • List all ADRs: adr list
  • Read a specific ADR: read_file docs/adr/NNNN-title.md

6. Generating Reports

  • Generate a Table of Contents: adr generate toc
  • Generate a dependency graph (requires Graphviz): adr generate graph | dot -Tpng -o adr-graph.png

Best Practices

  • Keep ADRs focused on a single decision.
  • Write for future maintainers who lack current context.
  • Update the status and links when decisions change.
  • Refer to references/adr-concepts.md for more details on the ADR philosophy.
  • Use the template in assets/template.md as a guide.
  • Draw a diagram with Mermaid to visualize the decision.
  • If needed, draw a system diagram, sequence diagram(s) and other diagrams with Mermaid.
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.
