architect

architect is a skill for Claude Code from angad-kandhari/deliberate. It costs 57 tokens per session (1,563 once invoked), scanned A, original, Apache-2.0.

Guidance for making sound decisions about how software components fit together. A component is a part of a system with its own responsibilities, and a boundary is the contract or dividing line between parts.

In plain words
What is it for?
Use it when a change crosses components, adds a service, changes a contract, or raises the question of where code should live.
Why use it?
It reduces misplaced code, accidental dependencies, unclear responsibilities, and risky changes to APIs, events, schemas, or function signatures.

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 9d 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.

Architect

Architectural thinking skill for LLM coding agents. Load this when the task crosses component boundaries, introduces a new service, reshapes a contract, or asks "where should this code live?"

Where deliberate keeps code honest and spec keeps product intent honest, this skill keeps structural decisions honest. Counters premature abstraction, boundary violations, and the silent blurring of component responsibilities.


1. Name the Boundary Before You Cross It

Every non-trivial change touches a boundary. State which one.

Before editing, identify:

  • Which component(s) own this code today.
  • Which boundary this change sits inside, crosses, or creates.
  • What the contract at that boundary is (API, event, schema, function signature).

If the change crosses a boundary that didn't exist before, you're introducing architecture. That's a bigger decision than an implementation. Slow down.

Test: Can I draw a box diagram of the touched components and point to the line my change crosses?


2. Put Code Where It Belongs, Not Where It's Convenient

Where code lives determines who can use it, change it, and break it.

Decide based on:

  • Ownership - which team or module is responsible for this behavior?
  • Change cadence - does this change with the UI, with the business rule, with the database?
  • Dependencies - what does this need to know about? The fewer the better.
  • Reuse - is this one-off, or will multiple callers need it?

Common anti-patterns:

  • Business logic in the controller/handler layer because it was "just faster."
  • Helpers that know about the database and the UI.
  • "Utils" dumping grounds that have no coherent responsibility.
  • Feature code in shared libraries because one other feature "might need it someday."

Test: If this code needs to change for a business-rule reason, does it live near other business-rule code?


3. Contracts Are Promises - Change Them Carefully

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 a skill published in the GitHub repository angad-kandhari/deliberate (2 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 57 tokens to every session and 1,563 once invoked, about $0.0003 per session on Opus 5. 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.
