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.

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 | $0.03334 | $0.03334 |
| Opus 5 | $0.01667 | $0.01667 |
| Sonnet 5 | $0.00667 | $0.00667 |
| Haiku 4.5 | $0.00333 | $0.00333 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 readsschema/schema.graphqland generates typed Rust code intocrates/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.

lineark CLAUDE.md is an instructions file published in the GitHub repository flipbit03/lineark (54 stars, last pushed 1mo ago), licensed MIT. It adds 3,334 tokens to every session, about $0.0167 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 2026-08-30.
