~aod-project-plan

~aod-project-plan is a skill for Claude Code, Codex from davidmatousek/agentic-oriented-development-kit. It costs 59 tokens per session (1,850 once invoked), scanned A, original, MIT.

A checker for architecture plans, which document how a software feature will be built. It reviews files such as plan.md for the technology choices, APIs, database design, security, project structure, and fit with the feature specification.

In plain words
What is it for?
Use it to validate a feature's architecture plan, check required sections, and review technical decisions before coding.
Why use it?
It catches missing or weak planning details before implementation begins, reducing the chance of building from an incomplete design.

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

~aod-project-plan 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 3d 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.

Architecture Validator Skill

Purpose

Automatically validates architecture documentation (plan.md) for completeness, technical rigor, and alignment with feature specifications. Implements FR-006 from the feature specification.

How It Works

Step 1: Locate Architecture Plan

  • Search for specs/*/plan.md files
  • If specific feature directory provided, validate that plan.md
  • Report if plan.md not found

Step 2: Validate Required Sections

Check for mandatory sections per AOD plan template:

Technical Context (Required)
  • Language/Version
  • Primary Dependencies
  • Storage solution
  • Testing approach
  • Target Platform
  • Project Type
  • Performance Goals
  • Constraints
  • Scale/Scope
Constitution Check (Required)
  • All 7 constitutional principles validated
  • Evidence for each principle
  • Violations justified (if any)
Project Structure (Required)
  • Documentation structure
  • Source code structure
  • File organization
Technology Stack (Required)
  • Languages and versions
  • Frameworks and libraries
  • Database and storage
  • Infrastructure components

Step 3: Check Technical Decisions

Verify technical decisions are documented:

  • data-model.md: Entity definitions and relationships
  • contracts/: API specifications (if applicable)
  • research.md: Technical unknowns resolved

Step 4: Validate Spec Alignment

  • Compare plan.md with spec.md
  • Check all functional requirements addressed
  • Verify success criteria have implementation strategy
  • Ensure out-of-scope items respected

Step 5: Security Architecture Check

Verify security considerations documented:

  • Authentication approach
  • Authorization model
  • Data protection strategy
  • API security measures
  • Secrets management

Step 6: Generate Validation Report

✅ Architecture Validation Report

File: specs/{feature-id}/plan.md

- [✓/✗] Technical Context
- [✓/✗] Constitution Check (7/7 principles)
- [✓/✗] Project Structure
- [✓/✗] Technology Stack

Design Artifacts:
- [✓/✗] data-model.md (entities defined)
- [✓/✗] contracts/ (API specs)
- [✓/✗] research.md (decisions documented)

Quality Checks:
- [✓/✗] All FRs from spec.md addressed
- [✓/✗] Security architecture documented
- [✓/✗] Performance targets specified

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.
