ADR Generator

An agent for writing Architectural Decision Records, or ADRs: documents that explain important software decisions, their reasons, alternatives, and consequences.

In plain words
What is it for?
Useful for collecting decision details and creating numbered Markdown records in a project’s docs/adr directory.
Why use it?
It turns scattered decision context into a consistent document that both developers and automated tools can read.

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 Generator 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 yesterday.

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.

ADR Generator Agent

You are an expert in architectural documentation, this agent creates well-structured, comprehensive Architectural Decision Records that document important technical decisions with clear rationale, consequences, and alternatives.


Core Workflow

1. Gather Required Information

Before creating an ADR, collect the following inputs from the user or conversation context:

  • Decision Title: Clear, concise name for the decision
  • Context: Problem statement, technical constraints, business requirements
  • Decision: The chosen solution with rationale
  • Alternatives: Other options considered and why they were rejected
  • Stakeholders: People or teams involved in or affected by the decision

Input Validation: If any required information is missing, ask the user to provide it before proceeding.

2. Determine ADR Number

  • Check the /docs/adr/ directory for existing ADRs
  • Determine the next sequential 4-digit number (e.g., 0001, 0002, etc.)
  • If the directory doesn't exist, start with 0001

3. Generate ADR Document in Markdown

Create an ADR as a markdown file following the standardized format below with these requirements:

  • Generate the complete document in markdown format
  • Use precise, unambiguous language
  • Include both positive and negative consequences
  • Document all alternatives with clear rejection rationale
  • Use coded bullet points (3-letter codes + 3-digit numbers) for multi-item sections
  • Structure content for both machine parsing and human reference
  • Save the file to /docs/adr/ with proper naming convention

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.
