Organize and standardize your AI agent knowledge.

Skill Index maps your local skills, MCP servers, and plugin capabilities - then helps you compare and repair drift across the AI agents you use. Runs entirely on your machine.

01 What it does

Your agents should know the same things.

100% local.

Skill Index runs on your machine and works with files on disk. Your skills, MCP configs, plugin inventory, and audit log stay local by default.

One shared body of knowledge.

Teach one agent a skill, install one MCP, or standardize one capability - then make it available consistently across the agents you use.

Find & fix drift before it becomes chaos.

Skill Index compares what each agent sees, then highlights missing, copied, symlinked, invalid, and drifting capabilities.

02 How it works

One pane for keeping your AI agents aligned.

Map

Find every skill and MCP on your machine.

Skill Index scans user-level skill directories, MCP configs, installed plugin capabilities, and any custom paths you add. Each source stays where it lives - nothing is moved.

  • Scans the folders your agents already use
  • Picks up plugin-provided capabilities as managed inventory
  • Add custom scan paths for repos you maintain

Compare

See what every agent sees.

For each capability, see whether it is canonical, copied, symlinked, missing, invalid, dismissed, healthy, or quietly drifting away from your other agents. Compare MCP definitions side by side.

  • Per-skill, per-MCP status across agents
  • Catch silent forks before they become hard to reconcile
  • See the exact files and configs behind each issue

Standardize

Resolve drift with the right level of control.

Some fixes are obvious. Others need context. Skill Index lets you batch-apply straightforward repairs, inspect diverged copies, and choose exactly how to reconcile tricky skills or MCP definitions.

  • Batch-apply straightforward repairs
  • Restore missing symlinks where agents support them
  • Inspect diverged copies before choosing a repair
  • Reconcile MCP definitions across agent configs

Audit

Every mutation, accountable.

A local audit log records every file-changing operation, with timestamps, paths, and the choice you made. Open it any time to confirm what changed.

  • Timestamped, append-only, on-disk
  • Filter by skill, MCP, agent, or operation
  • Roll back a single repair from history

03 Local-first

Local files stay local.

01
Runs on your machine.
No account, no cloud sync, no telemetry. App state lives under ~/.skillindex/ by default.
02
Works with files on disk.
Skills and MCP configs stay in the folders they came from. Skill Index reads, compares, and only with your approval repairs.
03
Repairs are reviewed before they apply.
Skill Index shows you the operation, the file, and the agent it affects before a repair runs.
04
Plugin capabilities are read-only inventory.
If something arrived through a plugin, Skill Index lists it as managed and refuses to mutate it.
