mcp-linear tests.instructions.md

Repository instructions for writing focused tests for mcp-linear tools and services.

In plain words
What is it for?
Use them when adding tests for MCP tool surfaces, service methods, validation rules, explicit null clearing, filtering, or normalized responses.
Why use it?
They ensure new behavior is tested on both successful and invalid inputs, including nullable updates, enum and number constraints, normalization, and GraphQL fallback behavior.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

mcp-linear tests.instructions.md 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 yesterday.

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.

What it actually says

Tests in this repository should be focused and MCP-specific.

  • Add narrow tests around the behavior introduced by the change instead of broad snapshots.
  • Cover at least one positive path and one negative or validation path for new tool surfaces.
  • When a service method uses a direct GraphQL fallback, test the expected normalized shape and any filtering logic.
  • When update inputs support null clearing, add a test that preserves explicit null values.
  • When schemas or guards add constraints like enums or positive integers, add tests that reject invalid values.
  • Prefer mocking the smallest possible surface of the Linear client or LinearService dependency needed for the scenario.
Changes

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.
