Skills Resource Guide¶

Researched Apr 18. Reference for installing community skills and building custom ones.

How Skills Work¶

Skills live in your .claude/skills/ folder on your machine. Each skill is a subfolder containing a SKILL.md file. Claude loads them automatically when relevant based on the description in the frontmatter.

Your skills folder location (Windows):

C:\Users\Katja\.claude\skills\

To install a skill: create a subfolder with a SKILL.md inside it.

Skills to Install — From GitHub¶

Run these in your VS Code terminal to clone community skill repos:

EAIconsulting — 21 Cowork skills (beginner → power user)¶

Built specifically for Cowork. Free forever. Highly recommended starting point.

git clone https://github.com/EAIconsulting/cowork-skills-library.git "C:\Users\Katja\Downloads\cowork-skills-library"

Then copy the skill folders you want into C:\Users\Katja\.claude\skills\

Skills to Build — Custom NEO Skills¶

These don't exist in any repo. Build them using the skill-creator skill (already installed).

1. `neo-session-debrief`¶

Trigger: "debrief", "log this session", "update experiment log", "write up S39" What it does: - Queries the live DB for session stats (fills, toxicity, VW spread, inventory) - Formats output for [C] Experiment Log.md - Drafts an Atlas alignment message - Updates CLAUDE.md with session result

2. `neo-pre-session-checklist`¶

Trigger: "pre-session check", "ready to run", "before I start the engine" What it does: - Confirms backup exists (FLAG-027) - Verifies config values match approved state - Runs DB integrity check (FLAG-033) - Reviews open flags for any blockers - Outputs: GO / NO-GO with reason

To build either: say "use skill-creator to build neo-session-debrief" and I'll draft the SKILL.md.

Skills Already in Cowork Directory (click + to add)¶

From Cowork's built-in Skills directory (Anthropic & Partners tab):

Skill	Useful for us?
`/internal-comms` (97.4K installs)	Yes — structured format for Atlas/Orion briefings
`/doc-coauthoring` (128.6K)	Maybe — co-authoring workflows
`/mcp-builder` (143.8K)	Future — if we build custom MCP connectors
`/web-artifacts-builder` (176.3K)	No — claude.ai only
`/canvas-design` (275.9K)	No
`/theme-factory` (139.5K)	No
`/brand-guidelines` (125.5K)	No
`/algorithmic-art` (97.6K)	No
`/slack-gif-creator` (72.1K)	No

Recommended to add now: /internal-comms — click the + button in the Skills directory.

GitHub Sandbox Access¶

GitHub is currently blocked from the Cowork sandbox egress proxy. To give Vesper access:

Option 1 — Set GITHUB_TOKEN (recommended): 1. Go to GitHub → Settings → Developer Settings → Personal Access Tokens → Tokens (classic) 2. Create token with repo read scope 3. In Cowork settings or your system environment, set: GITHUB_TOKEN=your_token_here 4. This lets the gh CLI authenticate — but note that egress to github.com is still blocked at the network level. Check with Anthropic support if this can be whitelisted.

Option 2 — Mount the cloned repos: Clone the repos you want on your Windows machine and they'll be accessible via the mounted filesystem. This is the reliable path today.
