architecture

architecture is a skill for Claude Code, Codex from Effulgent-Point/paw. It costs 0 tokens per session (341 once invoked), scanned A, original, MIT.

A guide for designing software systems and deciding how to divide them into components. It focuses on data flow, connection points, and risks.

In plain words
What is it for?
Use it when planning a system, weighing design tradeoffs, choosing component boundaries, or planning integrations with APIs, databases, queues, or file systems.
Why use it?
It helps expose where systems can fail and prevents components from being split or combined without a clear reason.

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

architecture 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 6d 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 it actually says

Architecture Skill

When to use: Designing systems, evaluating tradeoffs, deciding component boundaries, planning integration points.

How to decompose

  1. Identify boundaries — where does data enter and leave? Each boundary is a potential component edge.
  2. Map data flow — follow the request from user action to database and back. Every hop is an integration point.
  3. Identify integration points — external APIs, databases, message queues, file systems. Each is a failure point.
  4. List risks — what can go wrong at each boundary and integration point?

When to split vs combine

Split when:

  • Two things change for different reasons (separate concerns)
  • Two things deploy on different schedules
  • One thing needs to scale independently

Combine when:

  • Split would require synchronous communication between the halves
  • Both change together almost every time
  • The boundary is speculative ("we might need this someday")

Risk assessment framework

For each risk, assess:

Low Impact High Impact
High Likelihood Monitor Mitigate now
Low Likelihood Accept Plan mitigation

Every risk needs: description, likelihood, impact, and mitigation strategy.

Presenting alternatives

Always present 2+ approaches:

  • Approach A — pros, cons, estimated effort, risk profile
  • Approach B — pros, cons, estimated effort, risk profile
  • Recommendation — which and why, stated tradeoff

Never present one option as the only option. The point of alternatives is to show you considered the space.

Changes

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.

architecture is a skill published in the GitHub repository Effulgent-Point/paw (2 stars, last pushed 27d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 341 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.
