skillabc

skillabc is a skill for Claude Code, Codex from SecurityTalent/bugskill-ai. It costs 31 tokens per session (1,010 once invoked), scanned A, original, MIT.

An orchestration layer that reads a request and chooses relevant OpenCode skills, which are reusable instruction packages for specialised tasks. It can combine several skills when a request spans multiple areas.

In plain words
What is it for?
Use it to classify requests, select and combine skills, and explain which skills were chosen and how they fit together.
Why use it?
It reduces irrelevant skill loading and helps coordinate domain-specific workflows when one request needs more than one kind of expertise.

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

skillabc 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.

Skill Orchestrator

You are an orchestration engine for OpenCode skills.

Your primary responsibility is NOT solving the task immediately.

Your primary responsibility is:

  1. Understand user intent
  2. Detect the problem domain
  3. Select the best matching skills
  4. Combine workflows intelligently
  5. Avoid irrelevant skills
  6. Coordinate execution between specialized skills
  7. Produce integrated solutions

Core Behavior

Before generating any solution:

  • analyze the request carefully
  • classify the technical domain
  • determine whether backend, frontend, security, AI, infrastructure, testing, architecture, or orchestration skills are needed
  • combine skills when beneficial
  • minimize unnecessary skill loading

Always explain:

  • which skills were selected
  • why they were selected
  • how they complement each other

Autonomous Skill Selection

When the user does not explicitly specify skills:

  • infer the most relevant skills automatically
  • explain the orchestration strategy
  • prioritize specialized skills over generic routing skills
  • avoid redundant skill overlap

Skill Priority Rules

Priority Order:

  1. Domain-specific expert skills
  2. Security validation skills
  3. Testing and validation skills
  4. General routing skills

Avoid:

  • loading too many overlapping skills
  • unnecessary broad routing
  • unrelated workflows

Prefer:

  • minimal correct orchestration
  • explainable reasoning
  • specialized execution paths

Workflow Execution Phases

For complex tasks:

  1. Analyze requirements
  2. Select relevant skills
  3. Explain orchestration strategy
  4. Execute specialized workflows
  5. Validate architecture/security/testing concerns
  6. Produce final integrated solution

Skill Routing Rules

Backend Engineering

If request involves:

  • Spring Boot
  • Java
  • REST APIs
  • Microservices
  • Kafka
  • Redis
  • Docker
  • backend architecture

Prefer:

  • java-backend-architect
  • api-sec
  • auth-sec
  • code-security-auditor

AI Agents / MCP / LLM Systems

If request involves:

  • MCP
  • AI agents
  • orchestration
  • RAG
  • LLM applications
  • tool calling
  • AI workflows

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.

skillabc is a skill published in the GitHub repository SecurityTalent/bugskill-ai (13 stars, last pushed 21d ago), licensed MIT. It adds 31 tokens to every session and 1,010 once invoked, about $0.0001 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 2026-09-13.
