- Download or update the JLCPCB electronic components database for the jlcpcb-component-finder skill. Use when: (1) User says 'update jlcpcb db', 'download jlcpcb database', 'refresh parts database', (2) The jlcpcb-component-finder skill reports database not found, (3) User wants to get the latest component data from JLCPCB/LCSC, (4) User says 'update db', 'update parts db'. Downloads ~0.6 GB split-zip (~5 GB installed) from yaqwsx.github.io/jlcparts.
DO NOT auto-invoke this skill. This downloads ~0.6 GB and writes a ~5 GB database. Always ask for user confirmation before proceeding.
JLCPCB Database Updater
Download or update the JLCPCB parts database (~5 GB installed, ~7 million components).
Upstream now ships the slim source-db-v2 format (table jlc_components); the old
v1 format bundled a ~20 GB raw-payload table — this script drops it if it ever reappears.
Prerequisites
curl- for downloading files7z(p7zip) - for extracting split-zip archives. Install:brew install p7zipsqlite3- for the defensive slim-down step. Install:brew install sqlite
Update Script
Run the automated update script:
bash $HOME/.claude/skills/jlcpcb-component-finder-update-db/scripts/update-db.sh
This script will:
- Check prerequisites (
curl,7z,sqlite3) - Discover and download split-zip files from
https://yaqwsx.github.io/jlcparts/data/ - Extract
cache.sqlite3using7z - Back up existing database (if any) to
cache.sqlite3.bak - Install new database to
$HOME/.jlcpcb-db/cache.sqlite3 - Drop the legacy
jlcpcb_component_detailspayload table if present (no-op on v2) + VACUUM - Remove the previous
cache.sqlite3.bakso backups don't pile up - Clean up temporary files
Important Notes
-
Download size: ~0.6 GB compressed (12×50 MB split parts + a final ~13 MB zip)
-
Installed size: ~5 GB (
source-db-v2); the old v1 format was ~26 GB due to a raw-payload table -
Download time: usually a minute or two on a decent connection
-
Disk space needed: during the transition you briefly hold the old DB + new DB; the script
removes the
.bakautomatically after install -
If the download fails partway, re-run the script - it cleans up partial downloads
Data Source
Database from JLC Parts by Jan Mrazek. Updated periodically from JLCPCB/LCSC component data.
Verify After Update
node $HOME/.claude/skills/jlcpcb-component-finder/query.js db-info
Manual Update (Alternative)
If the script doesn't work, download manually:
- Visit https://yaqwsx.github.io/jlcparts/
- Download all
cache.z*andcache.zipfiles - Extract:
7z x cache.zip - Move:
mv cache.sqlite3 $HOME/.jlcpcb-db/

takazudo/dev-linkify-cc-resources
development
VerifiedTrustedCommunity
Link Claude Code skill names mentioned in a CodeGrid article (data/{series}/{n}.md) to the author's public claude-resources repo, pinned to the latest commit hash so links don't rot. Use when: (1) user says 'linkify cc resources', 'link the skills', 'link skill names', or invokes /dev-linkify-cc-resources; (2) editing a CodeGrid article that mentions `/commits`, `/pr-complete`, `/skill-creator` or other Claude Code skills and they should point to claude-resources. Only links skills that actually exist in the public repo; skips hypothetical examples and code blocks.

takazudo/opus-2nd
development
VerifiedTrustedCommunity
Second opinion from Claude Opus on a plan or approach. Use when: (1) Planning phase of /big-plan needs a higher-quality review than /codex-2nd / /gco-2nd, (2) User says 'opus 2nd' or 'opus opinion', (3) Wanting Anthropic's larger model to critique a plan. Spawns a general-purpose Agent with model: opus that reads the plan file and returns structured feedback. Anthropic quota — not free.

takazudo/dev-ai-based-test
tools
VerifiedTrustedCommunity
AI-based testing via subagent + a per-task test-flow skill. Use when the user wants to verify something that mechanical assertions can't fully capture — image recognition, visual size/position comparison, animation smoothness, multi-step manual flows that need AI judgment. Triggers: 'AI-based test', 'AI test', 'visual verify', 'image recognition test', 'manual operation test', 'human-eye check', 'verify visually', 'compare screenshots', 'looks the same', 'looks correct'. The skill's job is to (1) author a focused test-flow skill that captures the exact procedure + verdict criteria, then (2) dispatch a verification subagent via the Agent tool that loads BOTH the test-flow skill AND a browser-driving skill (/verify-ui primary, /headless-browser fallback) so the subagent has clear context and consistent verdicts. NEVER uses `claude -p` — subagent dispatch goes through the Agent tool exclusively.

takazudo/cleanup-resources
development
VerifiedTrustedCommunity
End-of-workflow audit of touched GitHub issues, PRs, and branches via a Sonnet subagent. Use when: (1) /big-plan, /x-as-pr, or /x-wt-teams finishes its main work and needs to verify every touched resource is in the right state (closed when done, kept when ongoing, deleted when dead), (2) User says 'cleanup resources', 'audit cleanup', or 'check what should be closed', (3) A long workflow ends and the manager wants a structured paper trail of what it closed/kept/deleted. Auto-execute by default — the Sonnet agent proposes, the manager (you) executes safe actions and prints a final report.
