v0.1 — Drift Diagnosis, Restore & Bundle

A Master Tailor for
Your AI Agent

Snapshot, compare, audit, restore, and bundle your coding agent environment —
with the precision of Savile Row craftsmanship.

By design, snaptailor is read-only. It never executes MCP commands, scripts, or plugins. It never phones home. It never alters your configuration without explicit consent. It stores metadata-first and omits raw secrets. The integrity of your workshop is our first principle.

Services of the Workshop

Every tool a master tailor needs to preserve the perfect fit.

Snapshot

Preserve the complete state of your agent — prompts, MCP servers, skills, tools, and settings — in a single point-in-time capture.

Semantic Diff

Pinpoint every change between any two snapshots. See prompt edits, MCP additions, permission shifts, env key changes, and more.

Security Audit

Spot risky alterations: executable config additions, remote MCP servers, permission wildcards, and reproducibility gaps.

Provenance

Trace every setting to its origin — MCP server, env key, skill, hook, permission — back to user config, project config, or agent type.

Restore & Rollback

Generate a restore plan, execute per-type file restoration, and roll back automatically with LIFO undo — all available now.

Export & Bundle

Export snapshots to portable .stailor bundles (POSIX tar, SHA-256 verified). Import and inspect without full unpacking.

Step Into the Workshop

$ npm install -g @qxinm/snaptailor
$ snaptailor scan --project .

Requires Node.js 22 or later

How to Use

Five steps to a perfectly fitted agent environment.

01

Measure

Scan your project to detect agents, MCP servers, skills, hooks, env keys, and settings.

snaptailor scan --project . --explain
02

Cut

Create a baseline snapshot. Snapshots are metadata-only; bundles include supported content by default.

snaptailor snapshot create --name baseline --metadata-only --project .
03

Fit

After changes, diff against baseline, audit for risks, and trace provenance.

snaptailor diff baseline current --project .
snaptailor audit current --project .
snaptailor provenance current --project .
04

Restore

Generate a dry-run plan, then apply with per-type file executors. Apply mode requires --experimental.

snaptailor restore --snapshot baseline --dry-run --project .
snaptailor restore --snapshot baseline --apply --experimental --project .
05

Bundle

Export snapshots to portable .stailor bundles. Preview Mac readiness before applying content.

snaptailor bundle export --name baseline --out backup.stailor --project .
snaptailor bundle inspect backup.stailor
snaptailor doctor --project .
snaptailor bundle import backup.stailor --dry-run --project .
