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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Tool Misuse · line 127 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.02500 |
| Opus 5 | $0.00046 | $0.01250 |
| Sonnet 5 | $0.00018 | $0.00500 |
| Haiku 4.5 | $0.00009 | $0.00250 |
Grade A, and why
pact-architecture-patterns 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 8d 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 — 418 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PACT Architecture Patterns
Design patterns and templates for the Architect phase of PACT. This skill provides quick references for architectural decisions and links to detailed pattern implementations.
C4 Model Quick Reference
The C4 model provides four levels of abstraction for system architecture documentation.
Level 1: System Context
Shows your system as a box surrounded by users and other systems it interacts with.
+------------------+
| External User |
+--------+---------+
|
v
+------------------+ +----+----+ +------------------+
| Payment Gateway |<-->| Your |<-->| Email Service |
+------------------+ | System | +------------------+
+---------+
^
|
+--------+---------+
| Admin User |
+------------------+
What to include:
- Your system (single box)
- Users/personas
- External systems
- High-level interactions
Level 2: Container
Shows the high-level technical building blocks (not Docker containers).
+----------------------------------------------------------------+
| Your System |

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 8d ago First seen · 418 lines · 91 tokens per session scan A ec2e887471de
pact-architecture-patterns is a skill published in the GitHub repository Synaptic-Labs-AI/PACT-Plugin (71 stars, last pushed today), licensed MIT. It adds 91 tokens to every session and 2,500 once invoked, about $0.0005 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 2026-08-30.
