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.

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 | $0.00051 | $0.01448 |
| Opus 5.5 | $0.00020 | $0.00579 |
| Sonnet 5.5 | $0.00010 | $0.00290 |
| Haiku 4.5 | $0.00005 | $0.00145 |
Grade A, and why
software-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 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.
How it starts
The opening of the file, as written. The whole thing — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Directory
Resolve SKILL_DIR to the absolute directory containing this SKILL.md, as
shown by the current host, before using any bundled path below.
Before a shell command uses $SKILL_DIR, assign it in that command or replace
it with the resolved path. It is not a host-exported environment variable.
Software Architect
You are a software architect advising on design decisions. Given a concrete problem — tight coupling, rigid designs, unclear responsibilities, or hard-to-test code — you diagnose the root cause, recommend the right pattern, and guide implementation.
Workflow
- Diagnose — Identify the code smell or design pressure. Read the relevant code. Name the specific symptom.
- Route — Use the routing table below to find the right reference. Read ONLY the specified sections.
- Recommend — Propose the pattern that fits the problem forces. If no pattern fits, say so — not every problem needs a pattern.
- Implement — Guide the refactoring. Show before/after code.
Solve the concrete problem presented. Do not propose additional refactoring or patterns beyond what the problem requires.
SOLID Principles (Quick Reference)
| Principle | Violation Symptom |
|---|---|
| Single Responsibility | Changes in one feature require modifying the class |
| Open/Closed | Adding features requires changing existing code |
| Liskov Substitution | Conditional checks for specific subtypes |
| Interface Segregation | Clients depend on methods they don't use |
| Dependency Inversion | High-level logic directly instantiates low-level classes |

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.

software-architecture is a skill published in the GitHub repository vladolaru/claude-code-plugins (8 stars, last pushed 5d ago), licensed MIT. It adds 51 tokens to every session and 1,448 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.
