About the project

SkillHub is a self-hosted registry where organizations publish, discover, version, and manage reusable skills for AI agents. Teams use it to share governed skill packages privately, with namespaces, role-based access control, audit logs, and CLI installation; the catalogue entries are skills and related agent integrations that can be managed through it.

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

decision-matrix 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 1mo 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.

Decision Matrix

What It Does

Apply a transparent framework to compare options, expose trade-offs, and identify what information could change a choice.

Treat every score as a transparent expression of the user's stated preferences, not as objective truth. Clearly label estimates and assumptions, and never invent missing costs, probabilities, constraints, or preferences.

For medical, legal, financial, safety-critical, or other high-impact decisions, use the frameworks only to organize questions and trade-offs. Do not present the highest score as professional advice or a final decision. Encourage the user to verify material facts and consult an appropriately qualified professional.


Frameworks Available

1. Classic Pros & Cons (Benjamin Franklin Method)

Best for: Quick decisions with low-to-moderate stakes

Step Action
1 Draw two columns: PROS and CONS
2 List every reason for and against — no filtering
3 Weigh each item (not all pros are equal). Assign +1 to +5 for pros, -1 to -5 for cons
4 Sum the scores, then inspect the strongest items, uncertainty, and any non-negotiables

Guardrail: Pros/cons alone miss hidden assumptions. Always follow with: "What am I not considering?"

2. Weighted Decision Matrix (Pugh Matrix)

Best for: Comparing multiple options against multiple criteria

| Criteria               | Weight (1-5) | Option A | Option B | Option C |
|------------------------|-------------|----------|----------|----------|
| Cost                   |      4      |   8/10   |   6/10   |   9/10   |
| Time to Market         |      3      |   7/10   |   9/10   |   5/10   |
| Strategic Fit          |      5      |   9/10   |   4/10   |   7/10   |
| Team Capacity          |      2      |   6/10   |   8/10   |   4/10   |
| **Weighted Total**     |             |   110    |   87     |   94     |

Steps:

  1. List all viable options (columns in the example)
  2. Define criteria that matter (rows in the example)
  3. Assign a weight (1-5) to each criterion based on importance
  4. Score each option per criterion (1-10)
  5. Multiply score × weight, sum across criteria
  6. Use the highest total as a starting point, then inspect assumptions, uncertainty, must-haves, and reversibility

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.
