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 →

    Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
    Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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

scaffold-addon 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 7d 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 — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Scaffold Addon

Create a complete addon package structure inside agentic/code/addons/.

Triggers

Alternate expressions and non-obvious activations (primary phrases are matched automatically from the skill description):

  • "I need a new addon" → scaffold addon with given name
  • "create an addon package" → prompt for name, scaffold
  • "build a new AIWG addon" → prompt for name and description
  • "new feature bundle" → clarify as addon, prompt for name

Trigger Patterns Reference

Pattern Example Action
Named scaffold "scaffold addon security-scanner" Scaffold directly
Interactive "scaffold addon --interactive" Guided design mode
Description-driven "create an addon for Python linting" Derive name=python-lint, confirm
With description "scaffold addon metrics --description 'Cost and token tracking'" Scaffold with description pre-set

Understanding Addons

Addons are self-contained feature bundles that extend AIWG without belonging to a specific lifecycle framework. Examples:

Addon Purpose
aiwg-utils Core meta-utilities (this addon)
voice-framework Voice profiles and writing style enforcement
testing-quality Test quality validation agents
rlm Reflection-learning memory patterns
ring-methodology Ring-based development methodology

Addons differ from frameworks:

  • Addons: Cross-cutting feature bundles, installed alongside frameworks
  • Frameworks: Complete lifecycle management systems (sdlc-complete, media-marketing-kit)

Process

1. Parse Arguments

Extract from $ARGUMENTS:

  • <name> — kebab-case addon name (required)
  • --description "<text>" — short description (optional; prompted if absent)
  • --author "<name>" — author name (optional)
  • --interactive — enable guided design questions
  • --core — mark as core addon (auto-installed with every AIWG install)

If <name> is missing, ask before proceeding.

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.
