hld-review

hld-review is a skill for Claude Code from DavidROliverBA/ArchitectKB. It costs 22 tokens per session (3,076 once invoked), scanned A, original, MIT.

A review skill for high-level design notes, which describe the planned structure of a software system. It compares the design with linked decisions, requirements, and architecture principles across six areas.

In plain words
What is it for?
Use it to review an HLD note and produce scored findings with severity levels and suggested next steps.
Why use it?
It helps reveal missing decisions, uncovered requirements, security gaps, and unclear integrations before implementation.

Skill for Claude Code

Written for Claude Code: context: fork in frontmatter. Also seen: model in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node .claude/scripts/graph-query.js --type=Concept --tag=conceptType/principle.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file 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

hld-review 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 11d 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.

The opening of the file, as written. The whole thing — 334 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/hld-review

Evaluate a High-Level Design (HLD) note against linked ADRs, requirements, and architecture principles. Produces a structured review with scoring across six dimensions, severity-rated findings, and actionable next steps.

Usage

/hld-review <HLD note title>
/hld-review HLD - Remote Vault Access Architecture
/hld-review HLD - SecureTransfer Azure Files to S3 Mirroring

Arguments

  • $ARGUMENTS: The title of the HLD note to review (required). Must match an existing HLD - *.md file in the vault root.

Review Dimensions

Dimension What Is Checked
ADR Coverage Does each significant design choice have a corresponding ADR? Are referenced ADRs accepted?
Requirements Traceability Are all referenced requirements (from relatedTo, project notes, linked concepts) addressed in the design?
Principle Compliance Does the design align with vault architecture principles (Concept notes with conceptType: principle)?
Security Architecture Are threat mitigations documented? Are security boundaries, encryption, and access controls explicit?
Integration Clarity Are system interfaces, data flows, protocols, and error handling paths clearly defined?
Operational Readiness Are monitoring, deployment strategy, runbook considerations, and rollback plans addressed?

Instructions

Phase 1: Load the HLD

  1. Parse the command — extract the HLD note title from $ARGUMENTS
  2. Find the HLD file — search for the file at the vault root matching the title
    • If not found, search using Grep for partial title matches across HLD - *.md files
    • If still not found, report the error and list available HLD notes
  3. Read the HLD note — load the full content including frontmatter and body
  4. Extract metadata:
    • relatedTo wiki-links from frontmatter
    • tags for domain context
    • confidence, freshness, verified quality indicators
    • Any inline wiki-links in the body text ([[...]] references)

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.
