Ai Face Reshape

AI-Face-Reshape

The AI Face Reshape API lets you programmatically reshape facial features — eyes, nose, lips, jawline, or the whole face — with pixel‑perfect control. Use it to generate before/after visualisations for rhinoplasty, chin fillers, lip augmentations, brow lifts and any other aesthetic‑treatment workflow.

Rhinoplasty (Nose Job) Our online rhinoplasty simulator offers medical-grade precision adjustments. Unlike generic photo editing apps, it allows for comprehensive simulation of specific details, including the Bridge, Lift, and Wing. With our hyper-realistic previews, clients can clearly visualize and explore their ideal proportions before consulting.
Chin Filler Through our online simulator, you can preview the ideal proportions achieved with chin fillers. Fine-tune Chin Length and Chin Shape to visualize improvements for a receding or short chin. Discover the optimal solution to balance your facial profile before undergoing any dermal filler treatments.
Lip Filler Users can experiment with different volumes and shapes of lip fillers to simulate the appearance of fuller lips, helping them decide on the desired outcome before undergoing the procedure.
Brow Lift Surgery This functionality enables users to preview the results of a brow lift, which involves lifting and reshaping the eyebrows to create a more youthful and rejuvenated appearance.

A3.8/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations provide no safety profile (readOnlyHint=false suggests mutation, but destructiveHint=false tempers that; openWorldHint=true indicates an open feature space, idempotentHint=false implies non-idempotent). The description communicates the breadth of the operation (many adjustable features) and the precision claim ('pixel-perfect control', 'medical-grade precision'), which adds context. However, it does not disclose operational details such as whether an uploaded or URL-based image is required, face-detection prerequisites (the 'index' parameter), cost implications, or what the response contains. Since the annotations carry little safety information, the description's limited disclosure keeps this at a 3.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is reasonably sized for the tool's complexity: a focused opening statement followed by four procedure-specific subsections that each map to controllable parameters. The substantive purpose is front-loaded, and the subsection structure aids scanning. It is somewhat promotional in tone ('hyper-realistic previews', 'medical-grade precision'), which adds length without functional value, but the overall structure remains efficient and navigable for an agent.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with a very rich input schema (30+ feature parameters) and an output schema present, the description is adequate: it explains the domain (aesthetic procedures) and provides parameter-to-procedure mappings that the schema itself does not. The schema and output schema cover the mechanics (input structure, output format), so the description's job was primarily to add business context and parameter guidance, which it does. Minor gaps remain (no mention of prerequisite detection, cost, or image constraints), but these are partially inferable from the schema's required fields (src_file_url/src_file_id) and sibling detection tools.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 50%, and the description adds meaningful use-case semantics that the schema lacks: it maps high-level parameters to specific procedures (e.g., 'Fine-tune Chin Length and Chin Shape' for chin fillers, 'Bridge, Lift, and Wing' for rhinoplasty). This helps an agent translate a user request into concrete parameter values. The in-schema coverage is already strong for some parameters (e.g., eye_size, chin_reshape, face_reshape explain bilateral behavior and per-side overrides), so the description's value-add is mostly at the feature-to-parameter mapping level. Given the large feature set, this contribution pushes the score above baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific verb ('reshape') and resource ('facial features'), enumerating the affected areas (eyes, nose, lips, jawline, whole face) and listing concrete use cases (rhinoplasty, chin fillers, lip augmentation, brow lifts). It distinguishes this tool from likely siblings like AI-Face-Lift and AI-Body-Reshape by focusing on discrete facial-feature reshaping with high precision. However, it does not explicitly name any sibling it is not, so the differentiation relies on the feature listing rather than an explicit contrast.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear use-case context by organizing the content around specific aesthetic procedures (rhinoplasty, chin filler, lip filler, brow lift) and stating that it is for 'aesthetic-treatment workflows' and pre-consultation visualization. This strongly implies when to use it: for generating before/after simulations on facial features. It does not explicitly state when NOT to use it or name alternative tools for other scenarios (e.g., full-face simulation via AI-Face-Lift), which keeps it a step below a 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
