Perception β†’ Context β†’ Safe action

Agents can go big when they see.

Loctree scans a live repository and turns it into structured, agent-ready context: files, symbols, surfaces, risks, and next actions.

Perception β†’ Context β†’ Safe action.

SCAN REGISTRY

OUTPUT SURFACES

One scan. Multiple surfaces.

One real `loct auto` scan emits seven artifacts. Pick a surface β€” the panel swaps to the actual output, copy-ready.

Actual scan output, copy-ready.

Structure
files, symbols, ownership
Surfaces
APIs, routes, events
Risks
cycles, dead, unsafe
Actions
impact, next safe edit

CONTEXT FIRST

Give agents context before they act.

01

Impact before commit

loct impact <file>

See every file that breaks.

02

Dead code, found

loct dead

Exports that nothing imports.

03

Context, not grepping

loct slice <file>

Core + deps + consumers.

04

Cycles detected

loct cycles

Circular imports mapped.

WORKS WHERE YOU WORK

Works where your repo works.

No special project shape required. Loctree follows the stack already in front of it.

WORKFLOW

From perception to safe action.

The same loop for humans and agents: read the repo, understand the blast radius, make a bounded change, verify the result.

AGENT SURFACES

Built for agents. Useful for humans.

CLIloct
Run Loctree on any repo from your terminal: scan, slice, impact, dead, cycles, doctor.
MCPcontext tools
Give compatible agents the same repo map humans use.
JSONartifacts
Export structured context for agents, reports, CI, and follow-up tools.
LOCALexplorer
Inspect the repository map without sending source code away.
