An information-architecture agent that organizes a product's content and screens. It creates sitemaps, screen inventories, navigation plans, user flows, and content strategies from an approved research brief.

Use it to plan website or application page hierarchies, navigation, search, responsive behavior, modal states, and task flows for different user types.

It turns research and requirements into a clear structure, making it easier to decide what screens exist and how people move through them.

info-arch — Agent for Claude Code by SufficientDaikon

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/SufficientDaikon/sdd-vscode-agents

Made for: Claude Code.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00033	$0.00687
Opus 5.5	$0.00013	$0.00275
Sonnet 5.5	$0.00007	$0.00137
Haiku 4.5	$0.00003	$0.00069

Measured 1mo ago against content hash b5c91f27829b, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

info-arch 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 1mo 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.

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.
