SKILL.md

Purpose

Install or update the dasel v3 binary from GitHub Releases into user-space (~/.local/bin on Linux/WSL2/macOS, %LOCALAPPDATA%\Programs\dasel on Windows). The install script handles platform detection, SHA256 verification, and PATH setup.

Install Script

The install script is a PEP 723 Python script at ${CLAUDE_PLUGIN_ROOT}/scripts/install_dasel.py.

Commands

Install or update to latest version:

bash
${CLAUDE_PLUGIN_ROOT}/scripts/install_dasel.py

Force reinstall (even if already at latest version):

bash
${CLAUDE_PLUGIN_ROOT}/scripts/install_dasel.py --force

Preview what would happen without making changes:

bash
${CLAUDE_PLUGIN_ROOT}/scripts/install_dasel.py --dry-run

Install to a custom directory instead of the default:

bash
${CLAUDE_PLUGIN_ROOT}/scripts/install_dasel.py --bin-dir /custom/path

Verify Installation

After install, confirm dasel is available:

bash
dasel --version

Expected output format: dasel version v3.x.x

Supported Platforms

  • Linux x86_64 (amd64)
  • Linux ARM64 (aarch64)
  • Windows x64 (native + WSL2)

WSL2 uses the Linux binary (dasel_linux_amd64), not the Windows .exe. The WSL2 environment is a full Linux subsystem.

Troubleshooting

"command not found" after install

~/.local/bin is not in PATH. Add it:

bash
export PATH="$HOME/.local/bin:$PATH"

Make persistent by adding to ~/.bashrc or ~/.zshrc:

bash
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

Download failures

  • Check internet connectivity: curl -I https://api.github.com
  • GitHub API rate limits: unauthenticated requests are limited to 60/hour. Set GITHUB_TOKEN environment variable for higher limits.
  • Retry with --force after transient failures.

SHA256 mismatch

The install script verifies the downloaded binary against the SHA256 digest from the GitHub API response. A mismatch indicates a corrupted download or tampered binary.

Fix: re-download with --force:

bash
${CLAUDE_PLUGIN_ROOT}/scripts/install_dasel.py --force

Permission denied

Ensure the install directory exists and is writable:

bash
mkdir -p ~/.local/bin
ls -ld ~/.local/bin

The directory should be owned by the current user with write permission.

ccc

This skill should be used when code search is needed (whether explicitly requested or as part of completing a task), when indexing the codebase after changes, or when the user asks about ccc, cocoindex-code, or the codebase index. Trigger phrases include 'search the codebase', 'find code related to', 'update the index', 'ccc', 'cocoindex-code'.

agent-browser

Browser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction.

knowledge-explorer

Manage the research/ knowledge base (KB) of tool and library research entries. Use when browsing KB topics, adding new research entries, updating existing entries with dated revisions, fetching GitHub repo metadata into a draft KB entry, or migrating old-format entries to skill-spec frontmatter. Triggers on tasks like "what do we have on X", "add this to the KB", "update the KB entry for Y", "fetch github info for owner/repo", or "migrate old entries".

design-anti-patterns

Enforce anti-AI UI design rules based on the Uncodixfy methodology. Use when generating HTML, CSS, React, Vue, Svelte, or any frontend UI code. Prevents "Codex UI" — the generic AI aesthetic of soft gradients, floating panels, oversized rounded corners, glassmorphism, hero sections in dashboards, and decorative copy. Applies constraints from Linear/Raycast/Stripe/GitHub design philosophy: functional, honest, human-designed interfaces. Triggers on: UI generation, dashboard building, frontend component creation, CSS styling, landing page design, or any task producing visual interface code.
