lsp-understand SKILL.md skillA

lsp-understand from blackwell-systems/agent-lsp is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add blackwell-systems/agent-lsp/lsp-understand@git:20261104.5790d48

Pins git:20261104.5790d48 in mdr.lock. Pin the fingerprint instead.

Deep-dive exploration of unfamiliar code — given a symbol or file, builds a complete Code Map showing type info, implementations, call hierarchy (2-level depth limit), all references, and source. Broader than lsp-explore: accepts files, synthesizes multi-symbol relationships, and produces a navigable dependency map.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# lsp-understand

Deep-dive exploration of unfamiliar code — given a symbol or file, synthesizes
hover info, implementations, call hierarchy (bounded to 2 levels), all
references, and source into a structured Code Map.

Read-only — does not modify any files.

## Differentiation from lsp-explore

`/lsp-explore` is a single-symbol pass: given one symbol name, it runs hover +
implementations + call hierarchy + references and produces a per-symbol report.
Use lsp-explore for quick "what is this one thing" questions.

`/lsp-understand` is broader in three ways:

1. **Accepts a file path as input** — explores all exported symbols in that file
   as a group (Mode B), rather than requiring a single symbol name.
2. **Synthesizes cross-symbol relationships** — produces a dependency map showing
   how entry points call each other, share callers, or implement the same
   interface, rather than isolated per-symbol reports.
3. **Enforces a 2-level call hierarchy depth limit** — prevents infinite recursion
   in deeply connected code.

Use lsp-understand for "how does this module work as a whole."

How to install

The exact contents, by fingerprint

mdr add blackwell-systems/agent-lsp/lsp-understand@sha256:1cc1d7abc177249a

The line at the top of this page pins the label git:20261104.5790d48, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
