What is using-typescript-lsp?

A guide for using a TypeScript language server with TypeScript and JavaScript code. It helps the coding agent find code connections, definitions, and type problems.

Use it to find references to a function or variable, jump to definitions, check types, and verify type correctness.

It reduces the need to search through files manually or guess whether code uses the right types. It requires the TypeScript language-server plugin to be enabled.

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	$0.00039	$0.01473
Opus 5.5	$0.00016	$0.00589
Sonnet 5.5	$0.00008	$0.00295
Haiku 4.5	$0.00004	$0.00147

Security

Grade B, and why

using-typescript-lsp scanned grade B with 1 finding 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.

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.
