Layer group (LayerSet) lifecycle and membership — choose the operation with `op`. create/delete/ungroup/add_layer/set_blend_mode. See the `op` enum for per-operation params. delete and ungroup are DESTRUCTIVE and require confirm:true — delete removes the group AND everything inside it; ungroup dissolves the group but promotes its contents to the parent level (use ungroup, not delete, to keep the layers).

Manage document guides — non-printing layout aids for a HUMAN working in Photoshop. Guides are editor-only chrome: they do NOT render into ps_get_preview (the exported/flattened image), so they are a user authoring aid, not a model-perception tool — place them when a person will open the PSD and wants alignment/composition marks. Choose with `op`. `add` places one guide (orientation horizontal|vertical) at a `position` in px. `layout` creates an evenly-spaced grid (columns and/or rows — great for rule-of-thirds at 3×3). `clear` removes all guides.

Read-only document inspection — choose with `what` (metadata / layer_tree / history / selection_info / smart_object). This is the assess/orientation surface: call it at the start of a workflow and whenever you need fresh state. For metadata, pass `sections` to subset (e.g. ["context"] for a cheap probe). For an IMAGE-based check use ps_get_preview; for NUMERIC verification use ps_get_histogram / ps_compare_regions / ps_get_layer_bounds_diff (these stay separate, named tools on purpose). Read-only and idempotent.

Manage the active layer's mask — choose with `op`. `create`: add a layer mask; if a selection is active it reveals the selection and hides the rest (the one-call "mask the placed image to the frame opening" — make the selection first, then create); with no selection, a reveal-all mask; adjustment layers load the current selection into their built-in mask. `delete`: remove the mask (layer pixels preserved). `apply`: DESTRUCTIVE — permanently bake the mask into the pixels (outside-mask pixels lost). `gradient`: draw a linear fade into the mask (fade_to names the side that ends hidden; start/end place the fade; auto-creates the mask; replaces existing mask content and clears any active selection first) — the standard fade for reflections, sky blends, and soft edge falloff. Verify with ps_get_preview. Prefer keeping masks non-destructive unless flattening for export. **Don't write `Mk Chnl At=Msk` or `Grdn` AM scripts in execute_script — this tool already does both.**

Live map of every tool this MCP exposes, grouped by capability — each group is a one-line purpose plus the tool names in it. Read-only and cheap. Reach for it to re-orient mid-session (what exists, what to reach for) when the overview brief has scrolled out of context, or to learn which tool names to look up. ps_overview tells you HOW to combine tools; this tells you WHAT exists, currently; tools/list has the full schema for any one you pick.

Merge layers — choose with `mode`. `visible`: collapse all visible layers into one (DESTRUCTIVE; identities lost). `stamp`: merge visible into a NEW layer on top, leaving originals intact (Ctrl+Alt+Shift+E — the non-destructive "final tweak" composite for output sharpening/grain/contrast; prefer this when building on top rather than collapsing). `flatten`: flatten ALL layers into the background (DESTRUCTIVE; transparency filled with bg color — use sparingly, usually prefer `visible` or exporting a flattened copy). Returns context.

Modify the CURRENT selection — choose with `op`. (To create a NEW selection instead, use ps_select.) `feather` softens by radius_px (use when a selection was made hard, e.g. after select all/inverse, before applying an adjustment). `refine_edge` runs Select-and-Mask's global sliders headlessly (smooth, feather, contrast, shift_edge, edge-detection radius, decontaminate) to clean halos and soft/fuzzy edges (hair) after a rough color-range / magic-wand / subject selection. `expand` / `contract` grow / shrink the selection by `amount` px. `border` replaces the selection with an `amount`-px band around its edge. `smooth` rounds the corners with an `amount`-px radius. `grow` / `similar` expand the selection to similar-colour pixels by `tolerance` (+anti_alias) — `grow` to adjacent pixels only, `similar` document-wide. `transform` relatively scales (scale_x_percent / scale_y_percent), rotates (rotate_degrees) and/or translates (offset_x / offset_y) the marching ants — pixels are untouched. All require an active selection and return selection_info.

Move a layer to a position in the stack — the single ordering primitive (the per-direction helpers `_to_top` / `_to_bottom` / `_up` / `_down` were removed 2026-05-31; this tool covers all four cases). Position keywords: ABOVE/BELOW (requires target_layer_name — places the moved layer immediately above/below the target), TOP/BOTTOM (absolute — target_layer_name not needed). By default the ACTIVE layer is moved; pass layer_to_move=<name> to move a specific layer by name (recurses into groups). COMMON CASES: an adjustment layer just created landed below another adjustment that masks its effect → move it to TOP; a vignette darkens the wrong layers → move ABOVE the layer it should affect; a sky-replacement composite is showing through the foreground → move the foreground to TOP. Idempotent for a given (layer_to_move, target, position).

Open a file from disk into Photoshop with all dialogs suppressed (uses last-used Camera Raw settings for raw/HEIC). Returns document name, dimensions, color mode, and whether the source was a raw format. `is_raw_source` is workflow-critical, not a passive status field: when true, the first edit should be a Camera Raw develop pass on the base smart object (via a camera-raw develop tool, if one is registered in tools/list) — NOT stacked tonal adjustment layers. Use this in the pipeline to load Inbox files for editing. If the file is ALREADY open, its existing document is activated rather than opened a second time — `already_open: true` says so, and any edits made to it are still there (Photoshop would otherwise open a duplicate with a fresh Background, which silently strands prior work).

Orientation brief for the entire MCP — workflow contract, capabilities map by category, verification primitives, escape-hatch policy, known gaps. READ THIS FIRST when the user gives you an open-ended editing task. Read-only, idempotent, no document required, no Photoshop call (returns a static markdown brief). Skip it for trivial single-tool requests where you already know which tool fits.

Work with editable vector PATHS — the connective tissue between selections, brush strokes, and clipping. One op-discriminated tool: `create_from_selection` (selection → work path), `create_from_placement` (NAME a curve → editable saved path, the grounded pen), `save` (name the work path), `list`, `delete`, `load_as_selection` (path → selection), `stroke` (paint a brush-family tool along a path), `fill` (fill a path region), `set_clipping` (mark a saved path as the clipping path). **Reach for this when**: tracing a named curve (an edge, a landmark contour) into an editable path, turning a precise selection into a reusable/strokeable outline, converting a saved path back to a selection, or outlining/filling a shape exactly. create_from_selection and load_as_selection are an exact round-trip. stroke/fill bake pixels and auto-duplicate the target layer. Every op returns path_info (counts + per-path subpath/anchor totals) so you can verify the path landed; load_as_selection also returns selection_info.

Test connection to Photoshop and report session-start discovery signals. Read-only and idempotent. Call this once at the start of a session to confirm liveness before invoking any other tool. **If the user has given you an open-ended editing task, ALSO call `ps_overview` after this** — it returns the workflow contract + capabilities map + verification primitives so you can plan well. Returns `version` (folds the removed get-version tool), `custom_action_sets` (count of Action Sets loaded in the Photoshop Actions palette — non-zero means recorded workflows exist; if action tools are available in this build they will appear in `tools/list`), `user_templates` (count of saved Editmamei templates), and `open_documents` (names of documents already open in Photoshop, so the LLM does not have to ask which doc to edit).

Place an image file (JPEG, PNG, PSD, etc.) as a new Smart Object layer in the active document, optionally offset from center. Rasterize separately if you need to apply pixel-only operations. Open-world: reads from the filesystem. Returns the new layer name, bounds, and updated document context.

Rasterize the active layer (convert text or smart object to plain pixels). Destructive — the text/smart-object source is lost. No-op if already a normal raster layer. Returns context so the caller sees the layer kind transition.

The full scene model — run this before a spatially-targeted edit, not the cheaper ps_detect: detected subjects (with the main one flagged) and faces in document pixels, a coarse sky/ground region map, the horizon line (y + placement + confidence), tonal zones (shadow/midtone/highlight bands + coverage), composition geometry (which thirds cell the subject sits in, balance, headroom), and the menu of selectable named regions. The structured model is complete on its own — pass `annotate:true` for an annotated preview JPEG when you actually need to see it drawn. Built using LOCAL on-device vision + classical CV; the image never leaves the machine. Select regions by name with ps_select_by_reference instead of guessing a rectangle. Read-only: renders a throwaway duplicate. Perception is cached per document state, so repeated reads are cheap.

Step forward in the document history (equivalent to Ctrl/Cmd+Shift+Z). Only works if ps_undo was the last operation; making a fresh edit destroys the redo stack. Returns updated context.

Run Photoshop's Sky Replacement (Adobe Sensei): detect the sky, composite a replacement, and relight/colour-grade the foreground to match. Non-destructive — everything lands in a "Sky Replacement Group" of editable layers above the original, so the result can be tuned or deleted afterwards. sky_file takes an ABSOLUTE path to ANY image on disk, not only Photoshop's built-in presets. Reach for harmonization_opacity and foreground_lighting_opacity when the composite reads as pasted-on; those two carry most of the believability. Fails cleanly when the image has no detectable sky (indoor or closed compositions).

Collect an ANONYMIZED diagnostic bundle and write it to the user's Downloads folder so they can attach it to a bug report — use when Editmamei misbehaves (won't connect, a tool keeps failing, unexpected results). The bundle holds recent server logs, system info (Editmamei/OS/Photoshop versions), and a content-free summary of recent tool calls (name, success, duration, error class). It contains NO image content, NO tool arguments, and file paths reduced to basenames. Does not touch Photoshop; writes one JSON file. After calling, tell the user the file path and that they can attach it to a new issue at https://github.com/editmamei/editmamei/issues.

Resize the entire document canvas (all layers) to the specified absolute dimensions. Destructive: downscaling permanently loses pixel data. Idempotent: same width/height always yield the same result. For aspect-preserving downscale during export, see ps_export (format=jpeg / png) which resize a duplicate. Returns updated document context.

Selection-driven content-aware retouch — choose the technique with `method`. Requires an active selection (throws if none, so Content-Aware Fill never silently fills the whole layer). Auto-duplicates the active layer by default so the original is preserved (auto-duplicate-first); pass `apply_to_active_layer: true` to bake into the original. `content_aware_fill` synthesizes a fill from surroundings (remove wires/objects/blemishes); `patch` samples replacement pixels from a chosen offset — or NAME the source region with `source_placement` (grounded + gated); `content_aware_move` relocates the selection and fills the source — offset, or NAME where with `destination_placement`.

Save the active document as a layered PSD to the given path. Saves as a copy, so the working document is unmodified and unrenamed. Use this in the pipeline to land an editable PSD into the Edit folder.

Create a NEW selection — choose with `mode`. (To edit the CURRENT selection instead — including growing it by colour similarity — use ps_modify_selection.) `all` selects the canvas; `none` deselects; `inverse` inverts the current selection (e.g. select the subject, then inverse to act on the background). `rectangle` (left/top/right/bottom, optional feather_px to avoid hard block-edges in smooth sky). `ellipse` (left/top/right/bottom bounding box + anti_alias — circles/ovals). `color_range` (target red/green/blue + fuzziness — "select all the red / skin tones"). `luminance_range` (highlights/shadows/midtones — foundation for glow / dodge-burn). `magic_wand` (click x/y + tolerance, contiguous). `focus_area` selects by depth of field rather than subject or colour (+in_focus_radius, soft_mask) — check whole_canvas_selected/warning in the result before trusting it. `grow` / `similar` are DEPRECATED here (they act on the CURRENT selection, not a new one) — use ps_modify_selection(op=grow|similar) instead; kept for one release for backward compatibility, identical behaviour. rectangle/ellipse/magic_wand also accept a grounded `placement` (NAME a region/point instead of guessing pixels — resolved + gate-verified). The geometric/color/wand modes take selection_type (replace|add|subtract|intersect) to combine with an existing selection and return a rich selection_info bundle — verify it (or ps_get_selection_preview) before committing to a mask.

Select a region by NAME instead of coordinates — the natural-mask alternative to a rectangle — with a CONFIDENCE GATE. target=sky/ground/foliage/subject/face/shadows/highlights/skin/above_horizon resolves through the right Photoshop-native method (threshold for sky, invert-sky−subjects for ground, luminance for shadows/highlights, skin-tone colour ∩ the subject box, the detected face/subject box) and is SCORED before it is offered: a clean region is left selected; an unconfident one is NOT selected and reported as honest absence (the city with no real sky gets no sky). Pro adds precise FACE-FEATURE targets backed by the face mesh — face_skin (the retouch mask: face minus eyes/brows/lips), face_eyes, face_brows, face_lips, face_teeth (mouth opening), face_nose, face_under_eye, face_cheeks — each a real geometry-following selection, derived on first request and then saved as a scene:face_* channel so repeats load instantly. `passed`/`confidence` are returned. A region derived here is cached as a `scene:*` channel keyed by TARGET ONLY, so a later call for the same target loads it by name; pass `refresh:true` to force a fresh derive after an edit that changes what the region means, and note that narrowing a call with `label`/`instance`/`composition_context` always derives (it neither reads nor writes that shared channel). The structural floor (coherence, horizon alignment) is never tuned; for an artistic/non-standard shot pass `composition_context` (e.g. profile:big_sky) to relax the compositional priors so a legitimately large sky is not rejected. For target=subject with several present, pass `label` and/or `instance`. Build/inspect with ps_read_scene first; verify with ps_get_selection_preview (the red-overlay is the human/agent oversight view). Prefer this over a rectangle for any real-world region.

Make a layer active by name. Recurses into groups; if a name appears more than once, picks the first match in stack order (top-to-bottom). Throws if no layer by that name exists. Foundational for multi-layer workflows — use after ps_duplicate_layer or ps_add_adjustment_layer when you need to focus a specific layer before applying further operations.

Run Photoshop's "Select Sky" (Adobe Sensei, PS 2021+). One-call sky masking for landscape work. Default sample_all_layers=true analyzes the full visible composite. Returns selection_info — high edge_complexity on tricky horizons (foreground objects against sky) is the signal to verify with ps_get_selection_preview before committing.

Run Photoshop's "Select Subject" (Adobe Sensei). One-call selection of the main subject — person, animal, product, etc. ~2-5s on typical images. Default sample_all_layers=true analyzes the full visible composite, which matches PS 2025 behavior and works around the PS 2026 "active layer only" default that fails opaquely when the active layer is a blurred / adjusted copy. Combines with existing selection via selection_type. Returns selection_info so the agent can verify area / edge complexity; if results look off, call ps_get_selection_preview for a visual. On failure, the error message lists fallbacks (Cloud processing in PS Preferences, manual UI selection).

Persist, restore, or manage a named Alpha channel — choose with `op`. `save`: store the current selection to channel_name (overwrites if it exists) so a complex AI/multi-step/feathered selection can be reloaded without rebuilding (throws if no active selection). `load`: restore a saved channel as the selection, with `operation` (replace|add|subtract|intersect) to combine — reapply one selection across layers. `duplicate`: copy an existing alpha/spot channel to a new one (optional new_channel_name). `delete`: remove an alpha/spot channel (won't touch the RGB/CMYK/Lab component channels).

Run an ordered list of tool calls against the current document in ONE round trip. WHEN TO REACH FOR THIS: several dependent steps you already know you want (e.g. select → adjust → merge, or a repeated resize/export pass) where you do not need to look at the result between them — each step is dispatched the same way an ordinary call is and sees the document exactly as the previous step left it. Not for exploratory work: if the next step depends on inspecting this one first, call the tools individually instead. Every step must name a tool that already exists in this edition (ps_sequence cannot call itself). An inline preview (image content) returned by a step is dropped unless that step is the LAST one in the sequence, since previews are most of a result's bytes and the point of batching calls is to stop paying for them on every intermediate step. Each step keeps its own time limit, exactly as it would if you called it on its own. The sequence's overall budget only decides whether to START another step, so it never cuts one off mid-run — a call can therefore finish after that ceiling by however long the in-flight step still needs, plus the undo and its verification reads when on_error='rollback'. With return='full', every step's complete result (not just the last one's) lands in the logged call payload.

Set a property of the active layer — chosen via `property`. Idempotent absolute setters; do not change which layer is active. `opacity`: pass opacity (whole layer incl. styles) and/or fill_percent (pixels only — Photoshop's separate "Fill" slider, for Hard Mix / stroke-only effects). `blend_mode`: how the layer composites below (NORMAL to reset). `visibility`: show/hide via `visible`. `locked`: allLocked via `locked`. `name`: rename via `name`. Returns context so the LLM keeps state awareness.
