Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00102 | $0.12811 |
| Opus 5 | $0.00051 | $0.06406 |
| Sonnet 5 | $0.00020 | $0.02562 |
| Haiku 4.5 | $0.00010 | $0.01281 |
Grade B, and why
sams-architecture scanned grade B with 2 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 12d 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.
Recursive force deletemediumDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
&& rm -rf /var/lib/apt/lists/* Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Sam's Architecture Standards
This skill codifies Sam's mature architectural patterns developed across 31+ personal projects and several client projects. It automatically applies during project planning, architecture reviews, and codebase audits.
CRITICAL: Zero-Tolerance Anti-Patterns
These are NEVER acceptable in Sam's personal projects. Flag immediately if detected:
Over-Engineering Anti-Patterns
❌ Premature Microservices: Breaking into microservices before you understand the domain boundaries
- Sam's rule: Start monolithic with clear module boundaries, split only when you have operational pain
- Example: Don't create separate services for "user-service", "auth-service", "notification-service" in a new project
❌ YAGNI Violations: Building features "because we might need them later"
- Sam's rule: Build what you need now, refactor when you need more
- Example: Don't add multi-tenancy support to a single-user API
❌ Abstraction Astronauts: Creating generic frameworks when specific solutions work
- Sam's rule: Three uses before abstracting. Copy-paste twice, abstract on third use
- Example: Don't create a "BaseAPIClient" with complex inheritance when you have one API client
❌ Configuration Complexity: Making everything configurable "for flexibility"
- Sam's rule: Hard-code sensible defaults, make configurable only when you need to change it
- Example: Don't create config files for things that never change per environment
Under-Engineering Anti-Patterns
❌ No Tests: "We'll add tests later" (narrator: they never did)
- Sam's rule: 80% coverage minimum on personal projects, tests written with code
❌ Missing CI/CD: Manual deployments, no automation
- Sam's rule: CI/CD setup is part of project initialization, not a "nice to have"
❌ Security as Afterthought: No authentication, secrets in code, no input validation
- Sam's rule: Security is non-negotiable from day one
❌ No Documentation: "The code is self-documenting"
- Sam's rule: CLAUDE.md + README.md are mandatory for all personal projects
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.

sams-architecture is a skill published in the GitHub repository sam-dumont/claude-skills (39 stars, last pushed 6mo ago), licensed MIT. It adds 102 tokens to every session and 12,811 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
