trustable-ai: Agent for Claude Code

.claude/agents/architect.md

architect is an agent for Claude Code from keychain-io/trustable-ai. It costs 0 tokens per session (865 once invoked), scanned A, original, MIT.

A software architecture guide for choosing technologies, splitting a system into components, and defining how those parts connect.

In plain words
What is it for?
It is for writing architecture decision records, designing APIs and data models, checking technology compatibility, and tracking technical risks and mitigations.
Why use it?
It helps prevent technology choices and system designs that do not fit the project, create security risks, or become difficult to maintain.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is keychain-io/trustable-ai's own configuration. It tells Claude Code how to work on trustable-ai itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything trustable-ai configures →

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

architect 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 2mo 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.

architect is an agent published in the GitHub repository keychain-io/trustable-ai (2 stars, last pushed 8mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 865 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
