update-linear-schema

A maintenance procedure for updating a Rust SDK's generated code from Linear's GraphQL schema. GraphQL is the interface Linear uses to describe and access its data.

In plain words
What is it for?
Use it to fetch a new schema, regenerate SDK types, update excluded fields or handwritten CLI code, and verify the workspace builds and tests pass.
Why use it?
It catches changes in Linear's public API and guides you through fixing code, formatting, warnings, and tests that the update may break.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 264 The whole file, excluding the scripts and references it only reads on demand.

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

update-linear-schema 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 3d 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.

What it actually says

Update the Linear GraphQL schema and fix any resulting breakage.

Steps:

  1. Run cargo run -p lineark-codegen -- --fetch to fetch the latest schema from Linear's public introspection endpoint and regenerate all SDK types.
  2. Run cargo build --workspace to check if everything compiles.
  3. If there are compilation errors (removed fields, renamed types, new required fields, etc.), fix them:
    • If a field was removed from the schema but is referenced in hand-written CLI code (crates/lineark/src/commands/), remove the reference.
    • If a field was removed but is still in a generated query's EXCLUDED_FIELDS list (crates/lineark-codegen/src/emit_queries.rs), remove it from the list and re-run codegen.
    • If a field exposed in introspection causes API errors (like featureFlags), add it to EXCLUDED_FIELDS and re-run codegen.
  4. Run cargo clippy --workspace -- -D warnings and fix any warnings.
  5. Run cargo fmt to fix formatting.
  6. Run cargo test --workspace to verify tests pass.
  7. Report what changed: new/removed types, fields that needed fixing, any EXCLUDED_FIELDS changes.
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.

update-linear-schema is a command published in the GitHub repository flipbit03/lineark (54 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 264 tokens. 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 2026-08-30.
