Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

linear-claude-skill 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 5d 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.

When to Use This Skill

Use this skill when working with manage linear issues, projects, and teams.

Linear

Tools and workflows for managing issues, projects, and teams in Linear.


⚠️ Tool Availability (READ FIRST)

This skill supports multiple tool backends. Use whichever is available:

  1. MCP Tools (mcp__linear) - Use if available in your tool set
  2. Linear CLI (linear command) - Always available via Bash
  3. Helper Scripts - For complex operations

If MCP tools are NOT available, use the Linear CLI via Bash:

# View an issue
linear issues view ENG-123

# Create an issue
linear issues create --title "Issue title" --description "Description"

# Update issue status (get state IDs first)
linear issues update ENG-123 -s "STATE_ID"

# Add a comment
linear issues comment add ENG-123 -m "Comment text"

# List issues
linear issues list

Do NOT report "MCP tools not available" as a blocker - use CLI instead.

🔐 Security: Varlock Integration

CRITICAL: Never expose API keys in terminal output or Claude's context.

Safe Commands (Always Use)

# Validate LINEAR_API_KEY is set (masked output)
varlock load 2>&1 | grep LINEAR

# Run commands with secrets injected
varlock run -- npx tsx scripts/query.ts "query { viewer { name } }"

# Check schema (safe - no values)
cat .env.schema | grep LINEAR

Unsafe Commands (NEVER Use)

# ❌ NEVER - exposes key to Claude's context
linear config show
echo $LINEAR_API_KEY
printenv | grep LINEAR
cat .env

Setup for New Projects

  1. Create .env.schema with @sensitive annotation:

    # @type=string(startsWith=lin_api_) @required @sensitive
    LINEAR_API_KEY=
    
  2. Add LINEAR_API_KEY to .env (never commit this file)

  3. Configure MCP to use environment variable:

    {
      "mcpServers": {
        "linear": {
          "env": { "LINEAR_API_KEY": "${LINEAR_API_KEY}" }
        }
      }
    }

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.
