Move every typed /buddy command off the LLM. cli/buddy.ts mirrors each config/state MCP tool (show, pet, stats, list, rename, personality, achievements, xp, upgrades, mood, memory, summon, save, dismiss, skin, frequency, style/position/rarity/width/margin/rainbow, statusline, theme, mute/unmute) with identical state writes, output, and achievements. The slash command now shells out to it; only proactive react/suggest stay on the model. buddy_save's advertised overwrite is honored (MCP tool throws).

Add server/custom-art.ts: an override layer that loads validated species JSON from /custom-art/ at runtime. It is keyed by name and never joins the RNG SPECIES pool, so existing buddies' deterministic rolls are untouched (adding to SPECIES re-rolls everyone — golden tests guard it). Ship fox as custom-art/fox.json for exactly this reason.

Verified: tsc clean, 246 tests pass, all commands exercised live.

Summary by CodeRabbit

• New Features
  • Added command-line commands for managing companions, achievements, upgrades, mood, memory, and settings.
  • Buddy commands can run without the MCP server when Bun is available.
  • Custom skins can override a buddy’s art and face across displays; a fox skin is included.
• Documentation
  • Added instructions for validating, installing, and activating custom skins, including their art format and appearance-only effects.

Hey @kitrakrev — nice feature set (the LLM-free dispatcher + runtime custom-art loader are both wanted). The PR currently conflicts with main, which recently absorbed a big rename (claude-buddy → coding-buddy), native Pi / Oh My Pi extensions, and npm publishing — package.json, server/art.ts, server/engine.ts, and skills/buddy/SKILL.md all moved under you. A rebase onto current main is the one blocker; CI is already approved to run here, and once it's green this is high on the review list.

🤖 Created with the help of AI (Claude Fable 5).

[kitrakrev]

Thanks @ramarivera — rebased onto current main (now on top of 0.9.4), conflicts resolved:

• core/engine.ts / server/art.ts: custom-art lookup kept, now layered on the new resolveEyeGlyph + core/ layout.
• server/custom-art.ts: resolves the state dir per call via buddyStateDir() (same lazy pattern as state.ts, so CLAUDE_CONFIG_DIR redirects are honored).
• cli/buddy.ts: imports moved to core/engine.ts / core/reactions.ts.
• skills/buddy/SKILL.md: dispatcher table.

tsc --noEmit clean, bun test 475/475 passing locally. Could you take a look when you get a chance?

Update: CodeRabbit's 7 findings are addressed in 1d1f2e6. The CI and TUI Golden runs are waiting on maintainer approval (action_required, since this is a fork PR). Could you hit Approve and run when you get a chance?

📝 Walkthrough

📝 Walkthrough

Walkthrough

This change adds a Bun-based buddy CLI for companion and configuration commands. It routes typed buddy commands through the CLI and adds runtime-loaded custom art overrides for companion frames and faces.

Changes

Buddy CLI and Custom Art

Layer / File(s)	Summary
Load and render custom art server/custom-art.ts, server/art.ts, core/engine.ts, cli/show.ts, cli/tui.tsx, server/index.ts, server/state.ts, custom-art/*	The server loads validated custom art JSON files and uses available frames and face templates as overrides. Companion renderers pass skin names to the art lookup. The change adds a fox skin and documents the custom art format and activation steps.
Add companion and skin commands cli/buddy.ts	The CLI loads or creates an active companion, displays companion information, manages saved slots and companion details, and lists or applies custom skins.
Add state, memory, and configuration commands cli/buddy.ts	The CLI adds achievement, XP, upgrade, mood, memory, configuration, status-line, mute, and unmute commands.
Wire CLI dispatch and command routing cli/buddy.ts, package.json, skills/buddy/SKILL.md	The CLI dispatches command names to handlers. The package adds a Bun script and publishes the custom art directory. The buddy skill routes typed commands through the CLI.

Merge Risk: 🔵 Low · up to 1d1f2

Applying or resetting a skin can unexpectedly unmute the status line. This is a narrow, recoverable configuration surprise; preserve the mute setting in both paths.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 1d1f2

Custom skins introduce a new path from imported JSON into terminal output. Runtime validation checks structure but allows terminal control sequences in art and face strings. Exposure is bounded to consumers of the same local or explicitly shared state directory; cross-user write access remains unverified.

Retained concerns

• Medium · security · observed: The new runtime loader accepts control characters in frame and face strings and forwards them into terminal and status output. A crafted imported skin can therefore provide terminal instructions rather than bounded display text. Runtime shape validation does not enforce the documented no-ANSI rule, and the separate validator does not inspect face templates for escape sequences. Exploitation requires importing a crafted file or obtaining write access to the art directory; broader cross-user exposure is unresolved.

Security review details

Security Blast Radius

• inferred — Art-file influence reaches renderers using the same resolved state root. A species-named JSON override can affect matching companions without explicit skin selection. Shared-root consumers inherit that influence, but cross-user attacker access depends on filesystem permissions not established by the repository evidence.

Security Findings and Attack Paths

• observed — The introduced path is crafted art JSON to runtime loading to frame or face substitution to terminal output. Status-output truncation preserves escape sequences rather than rejecting them. This establishes control-sequence propagation, not shell execution, credential access or a verified effect in every terminal host. Unrestricted state-directory writers already controlled other displayed text at the base.

Trust Boundaries and Controls

• observed — The loader requires three five-line frames, string content and an optional string face, and uses a null-prototype name map. Invalid individual files are skipped; explicit skin selection checks loaded names; eye substitutions remain constrained. These controls do not enforce safe terminal text. The documented validator is separate, checks only a subset of escape sequences in frames, and performs no escape-sequence check on faces.

Resilience and Maintainability Implications

• observed — Per-file parse and shape failures are contained by skipping the affected file. Structurally valid unsafe text is not rejected, however, and process-local caching retains accepted content until process replacement, limiting immediate recovery from an unsafe override.

Hardening Proposals

• proposed — Use one enforced runtime text policy for names, frame lines and faces: reject terminal control characters and embedded line breaks where inappropriate, apply bounded lengths, and reuse that policy in the validator. Keep intentional renderer-generated styling separate from imported art data.
• proposed — Define trusted writers and filesystem isolation for custom-art directories, especially shared roots, and document how to remove an unsafe override and refresh processes that cached it.

New skins adorn the frames once more.
The fox face grins in lines of art,
Commands keep each companion’s heart.

Review comments at @cli/buddy.ts:
- Around line 287-291: In the companion-slot save flow, replace the broad catch
around saveCompanionSlot with an existence check using
loadCompanionSlot(targetSlot): updateCompanionSlot only when the slot exists,
otherwise call saveCompanionSlot. Increment buddies_collected only when creating
a new slot, not when overwriting one.
- Around line 352-355: Update cmdSkin to preserve companion.bones.species and
store the custom skin name in a separate companion.skin field; pass that field
to art lookups that need the custom name. Add a skin reset command that clears
the custom skin and restores the default appearance without changing the buddy’s
species.

Review comments at @custom-art/README.md:
- Line 8: Update the README reference to the `SPECIES` definition to use
`core/engine.ts` instead of `server/engine.ts`; leave the surrounding
description unchanged.

Review comments at @server/custom-art.ts:
- Line 61: Initialize the custom-art map `out` with a null prototype in the
function containing the `isValidShape(data)` assignment, so file-provided names
such as `__proto__`, `constructor`, and `toString` are stored and retrieved as
own keys by `getCustomFrames`.

Review comments at @skills/buddy/SKILL.md:
- Around line 38-42: Align the opening guidance and fallback step 4 with the CLI
dispatcher’s typed-command behavior: route supported typed `/buddy` commands
through `cli/buddy.ts` even when MCP tools are unavailable, and limit the stop
rule to commands that still require MCP, including `buddy_react`,
`buddy_suggest`, and the `uninstall` row’s `buddy_uninstall` call.
- Around line 76-77: Update the rainbow and statusline argument entries in the
command table so their pipe characters cannot split table cells; use a
rendering-safe representation or move those arguments outside the table, and
ensure the displayed alternatives remain clear.
- Around line 44-46: Update the command example in the skill instructions to
resolve `cli/buddy.ts` from the plugin root using `CLAUDE_PLUGIN_ROOT`, so it
works when run from any project directory.
