Lsp Onboard

What it does

When your agent uses it

• Tasks that involve Software architecture

Example prompts

• “/lsp-onboard”

Requirements

• Compatibility (from SKILL.md): Requires the agent-lsp MCP server (github.com/blackwell-systems/agent-lsp)
• Pre-approved tools (allowed-tools): mcp__lsp__start_lsp, mcp__lsp__detect_lsp_servers, mcp__lsp__list_symbols, mcp__lsp__find_symbol, mcp__lsp__blast_radius, mcp__lsp__run_build, mcp__lsp__run_tests, mcp__lsp__get_diagnostics, mcp__lsp__get_editing_context

Workflow steps

8 steps, taken from the step headings in SKILL.md.

1. 1Detect languages and servers
2. 2Initialize and verify
3. 3Identify entry points
4. 4Map the package structure
5. 5Detect build and test commands
6. 6Identify hotspots
7. 7Check for diagnostics
8. 8Produce the project profile

What it can do on your machine

Read from SKILL.md and the folder at commit 38ca488. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • mcp__lsp__start_lsp
  • mcp__lsp__detect_lsp_servers
  • mcp__lsp__list_symbols
  • mcp__lsp__find_symbol
  • mcp__lsp__blast_radius
  • mcp__lsp__run_build
  • mcp__lsp__run_tests
  • mcp__lsp__get_diagnostics
  • mcp__lsp__get_editing_context

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md.

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

• Compatibility

  Requires the agent-lsp MCP server (github.com/blackwell-systems/agent-lsp)

  From compatibility in the SKILL.md frontmatter.

Context cost

Lsp Onboard loads about 1.2k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 391 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~61

When it runs · the whole SKILL.md, loaded when a task matches

~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

lsp-onboard

description

First-session project onboarding. Explores the project structure, detects build system, test runner, entry points, and key architecture patterns. Produces a structured project profile the agent can reference throughout the session.

## Project Profile: <name>

### Languages
- Go (primary), TypeScript (frontend)

### Build & Test
- Build: `go build ./...` (passes)
- Test: `go test ./...` (142 tests, 0 failures)

### Entry Points
- cmd/server/main.go:15 (main)
- cmd/worker/main.go:22 (main)

### Package Map
- cmd/server/     (HTTP server, routing)
- cmd/worker/     (background job processor)
- internal/api/   (handler layer)
- internal/store/ (database access)
- internal/types/ (shared type definitions)

### Hotspots (most referenced)
1. internal/types/models.go: 85 callers across 12 files
2. internal/store/queries.go: 42 callers across 8 files
3. internal/api/handlers.go: 31 callers across 6 files

### Pre-existing Issues
- 0 errors, 2 warnings (unused imports in test files)

### Conventions Observed
- Error wrapping with fmt.Errorf
- Table-driven tests
- Handler functions return (result, error)
