Based on SOC occupation classification
Create effective skills for OpenCode agents. Load FIRST before writing any SKILL.md. Provides required format, naming conventions, progressive disclosure patterns, and validation. Use when building, reviewing, or debugging skills.
Comprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task.
Generate hierarchical AGENTS.md knowledge base for a codebase. Creates root + complexity-scored subdirectory documentation.
Create, update, transition, and manage Jira tickets. Use when working with Jira issues, tracking work, or automating ticket workflows.
Multi-repository codebase exploration. Research library internals, find code patterns, understand architecture, compare implementations across GitHub/npm/PyPI/crates. Use when needing deep understanding of how libraries work, finding implementations across open source, or exploring remote repository structure.
Dialogue-driven spec development through skeptical questioning and iterative refinement. Triggers: "spec this out", feature planning, architecture decisions, "is this worth it?" questions, RFC/design doc creation, work scoping. Invoke Librarian for unfamiliar tech/frameworks/APIs.

Detect the version control system in use before running any VCS commands.
git commands in a jj repo (or vice versa) causes errors.jj/ and .git/ exist)Both jj root and git rev-parse --show-toplevel walk up the filesystem to find repo root.
Priority order:
jj root succeeds โ jj (handles colocated too)git rev-parse succeeds โ gitif jj root &>/dev/null; then echo "jj"
elif git rev-parse --show-toplevel &>/dev/null; then echo "git"
