What is lineark CLAUDE.md?

A repository instruction file for lineark, an unofficial Rust toolkit for Linear, a project and issue-tracking service. It describes the workspace's libraries, command-line tool, code generator, and development rules.

Use it when working on lineark's Rust SDK, command-line tool, procedural macro, or generated API code. It also points to the project's architecture and planning documents.

It gives coding agents the project structure and conventions they need before changing code. This reduces the risk of editing the wrong crate or overlooking required validation.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03334	$0.03334
Opus 5.5	$0.01334	$0.01334
Sonnet 5.5	$0.00667	$0.00667
Haiku 4.5	$0.00333	$0.00333

Security

Grade A, and why

lineark CLAUDE.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 2mo 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.

CLAUDE.md — lineark

What is this

lineark is an unofficial Linear (issue tracker) ecosystem for Rust:

lineark-sdk (crates/lineark-sdk/) — Async-first Rust SDK for the Linear GraphQL API
lineark-derive (crates/lineark-derive/) — Proc macro crate providing #[derive(GraphQLFields)] for type-driven field selection
lineark (crates/lineark/) — CLI for humans and LLMs, powered by lineark-sdk
lineark-codegen (crates/lineark-codegen/) — Internal tool that reads schema/schema.graphql and generates typed Rust code into crates/lineark-sdk/src/generated/

See docs/MASTERPLAN.md for the full architecture, roadmap, and design decisions (huge file, only read if needed, to keep token consumption down in day-to-day work).

Key commands

rustup update stable                     # sync local toolchain with CI (do this before developing)
cargo run -p lineark-codegen             # regenerate SDK types from schema
cargo run -p lineark -- <args>           # run the CLI
make check                               # lint + doc + build (no tests)
make test                                # offline tests (unit + integration, fast, no API token)
make test-online                         # online tests (live API, serial, needs token)

make check && make test is the canonical local pre-push check. Add make test-online when you have a test API token and need full coverage.

Online tests must run serially. They hit the live Linear API, which has plan-level limits (e.g. max teams). Running them in parallel causes spurious failures from resource exhaustion. make test-online handles this automatically.

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.
