Compile a skin spec and review it. Returns a review sheet image (front | back | right | left views + raw texture), the review (score, issues with JSON paths and fix hints, art checks, craft advice, suggested next steps) and, on request, the texture (64×64 for a player skin), a text render and a close-up of some parts. Deterministic; never modifies files.

Apply a patch to a spec (update, replace, add or remove layers by id; change palette, legend or meta) and render the result like texel_render. Layers without an id first get "-" and keep it, so the next patch can use the same ids. Entries that cannot apply are skipped and reported. With "spec", returns the patched spec, the review and the sheet. With "file", writes the patched spec back to that file and returns only the review and the sheet.

Check a spec for errors and warnings without rendering images. Cheap; use it after every edit.

Compile a spec and write .png (the skin), .skin.json (the source) and optionally .sheet.png into the workspace (/app). Refuses specs with errors.

Start (or reuse) a live session and return a studio URL for the user. While it runs, every texel_render result appears in their open browser tab immediately, so they can watch the skin evolve and give feedback mid-way. Call it before the first render and share the URL with the user.

Store the spec on https://www.texel.dev.br and return a short link (https://www.texel.dev.br/s/) that opens the exact skin in the studio. Falls back to a long self-contained link when offline.

Load the spec behind a Texel share link (https://www.texel.dev.br/s/, a bare id, or a long studio link with #z= / #spec=) so you can keep developing an existing skin. Returns the spec JSON.

Expand a family (base spec + variants and/or a matrix of axes) and review every member. Returns a lineup image (front and back of each member, in order) and a per-member score table.

Expand a family and write /.png and .skin.json for every member, plus /lineup.png, into the workspace (/app). Refuses families with errors.

Convert an existing PNG in the workspace into an editable spec, one layer per painted face, palette keys c01…cNN. A player skin (64×64 or legacy 64×32) by default; pass layout for a mob, armor, cape, item or block texture. Rename palette keys to material names before editing.

Read a reference PNG in the workspace (concept art, a photo of a figure, another skin) and return its main colors, most common first, each with a role (shadow, midtone, highlight, neutral, accent), as a ready spec "palette" and "legend". Use it to match a reference instead of guessing hex values; derive the other tones with "~" steps.

Compare two specs pixel by pixel and report which faces changed. Use it to confirm a patch touched only what you intended. Returns the changed-pixel mask over the texture map (magenta = changed).

Return a complete, working example spec to learn from or fork. Skins: explorer, knight, robot, astronaut, wizard, cozy, winged-pig, miner-zombie, creeper, mud-pig, bronze-armor, banner-cape, ember-blade. Family: guild.

Read a documentation page as markdown. Pages: protocol (Skin Agent Protocol), spec (Skin spec reference), art-guide (Skin art guide), families (Skin families), api (Agent interfaces), install (Install as a tool). Read "spec" before writing your first spec.
