What is lsp-tools copilot-instructions.md?

A set of project instructions for adding and maintaining language-server support in the lsp-tools Claude Code plugin. It covers priorities, important files, commands, hooks, and installation steps.

Use it when configuring language-server support, checking server status, or adding a new programming language to the plugin.

It gives coding agents consistent rules for making small, reviewable changes and keeping documentation, setup files, and language support in sync.

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.

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	$0.00292	$0.00292
Opus 5	$0.00146	$0.00146
Sonnet 5	$0.00058	$0.00058
Haiku 4.5	$0.00029	$0.00029

Security

Grade A, and why

lsp-tools copilot-instructions.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 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

Copilot instructions

You are working in a Claude Code plugin for LSP-first code intelligence with strong enforcement patterns.

Priorities

Keep changes small and reviewable.
Update README.md and CHANGELOG.md when changing user-facing behavior.
Maintain the Three Iron Laws enforcement in SKILL.md.

Key Files

.claude-plugin/plugin.json - Plugin manifest
commands/lsp-setup.md - /lsp-setup command for project configuration
skills/lsp-enable/SKILL.md - Main enforcement skill with Three Iron Laws
skills/lsp-enable/references/ - Per-language LSP sections and hooks

Commands

Setup: /lsp-tools:lsp-setup (configures hooks and CLAUDE.md for detected languages)
Verify: /lsp-tools:lsp-setup --verify-only (checks LSP server status)

When Adding Language Support

Create references/{language}-lsp-section.md with CLAUDE.md guidance
Create references/{language}-hooks.json with development hooks
Add installation scripts to scripts/bash/ and scripts/powershell/
Update lsp-server-registry.md with installation commands
Update SETUP-GUIDE-ALL-LANGUAGES.md
Update README.md supported languages table

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.
