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 | $0.00239 | $0.01694 |
| Opus 5 | $0.00120 | $0.00847 |
| Sonnet 5 | $0.00048 | $0.00339 |
| Haiku 4.5 | $0.00024 | $0.00169 |
Grade C, and why
lsp-setup scanned grade C with 2 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 2d 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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LSP Setup
Configure the right Language Server for a project so the lsp MCP tools
(diagnostics, goto_definition, find_references, symbols, rename)
actually work. This skill is an index: detect what a project needs, install the
server, write the config, then verify with a real roundtrip.
The list of servers we ship as builtin is the source of truth in
packages/lsp-tools-mcp/src/lsp/server-definitions.ts (BUILTIN_SERVERS +
LSP_INSTALL_HINTS). The per-language references below mirror it.
PHASE 0 — LANGUAGE GATE (run first)
Identify the language from the file extension, then read the matching reference before installing or configuring anything.

WORKFLOW — detect → install → configure → verify
1. Detect
Scan the project to see which languages are present and whether each server is installed and configured:
bun scripts/detect-lsp.ts <projectDir> # human report (default: cwd)
bun scripts/detect-lsp.ts <projectDir> --json
What ships with it
25 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

lsp-setup is a skill published in the GitHub repository code-yeongyu/lazycodex (3,363 stars, last pushed 23d ago), licensed MIT. It adds 239 tokens to every session and 1,694 once invoked, about $0.0012 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
