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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00015 | $0.03584 |
| Opus 5 | $0.00008 | $0.01792 |
| Sonnet 5 | $0.00003 | $0.00717 |
| Haiku 4.5 | $0.00002 | $0.00358 |
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
Manage Linear issues, projects, and teams
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:
- MCP Tools (mcp__linear) - Use if available in your tool set
- Linear CLI (
linearcommand) - Always available via Bash - 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 $LINEAR_API_KEY
printenv | grep LINEAR
cat .env
Setup for New Projects
-
Create
.env.schemawith@sensitiveannotation:# @type=string(startsWith=lin_api_) @required @sensitive LINEAR_API_KEY= -
Add
LINEAR_API_KEYto.env(never commit this file) -
Configure MCP to use environment variable:
{ "mcpServers": { "linear": { "env": { "LINEAR_API_KEY": "${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.

linear-claude-skill is a skill published in the GitHub repository Agent-Threat-Rule/agent-threat-rules (388 stars, last pushed today), licensed MIT. It adds 15 tokens to every session and 3,584 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
