Codia Design Skills

Codia Design Skills

This is the root router skill for the Codia Design Skills pack. In the normal npx skills add install flow, agents load this top-level skill first. The feature and workflow skills under skills/ are supporting instructions that this router reads when the request needs a specific capability.

Use Codia through the local codia-design CLI. The CLI performs authenticated requests to Codia Open API and writes local downloads when commands return files.

Runtime Setup

Before running a Codia command, check whether the CLI is available.

macOS / Linux:

command -v codia-design

Windows PowerShell:

Get-Command codia-design -ErrorAction SilentlyContinue

If codia-design is missing and the user allows global npm installs, install the runtime:

npm install -g @codia-ai/codia-design-cli

Then verify:

codia-design --help
codia-design auth status

If global npm install is blocked, tell the user to run the same install command manually, then continue after they confirm it is installed.

Authentication

Check auth before billable work:

codia-design auth status

If disconnected, prefer browser login:

codia-design auth login --platform codex

If browser login is unavailable and the user provides an API key, bind it without echoing the value:

codia-design auth set --api-key api_key_xxx

The CLI stores auth state in ~/.codia/design-skills/config.json. Never print this file or API keys.

Routing Rules

Read the matching child skill before running commands that need parameters, model choices, polling behavior, or multi-step sequencing. Resolve paths relative to this root SKILL.md.

Prefer a workflow skill when the user asks for a real outcome with multiple deliverables. Prefer a feature skill when the request is a single clear operation.

Common Workflow Choices

Use skills/codia-product-assets/SKILL.md when the user wants a product or ecommerce deliverable such as a listing image set, product launch asset pack, store banner, white-background product tile, or lifestyle scene variants.

Use skills/codia-campaign-assets/SKILL.md when the user wants campaign or social creative, such as a poster plus adapted 1:1, 4:5, 9:16, banner, or thumbnail versions.

Use skills/codia-document-deck/SKILL.md when the user wants to turn PDFs, reports, screenshots, or existing design files into editable design data, a PPTX deck, or both.

Command Rules

• Prefer local file paths when the user provides local assets.
• Use --out for large JSON responses.
• Use --download-dir DIR when the user asks where outputs should go.
• Use --no-download only when the user explicitly wants JSON-only behavior.
• For PDFs, Codia page numbers are zero-based: page 0 is the first page.
• For pdf-to-ppt, use the CLI polling/download flow and validate the returned PPTX. Do not rasterize the PDF locally or create a substitute deck unless the user explicitly asks for a local fallback.
• For image generation, keep the first call simple when the user has not specified model or size. The CLI default is seedream_5 at 2560x1440.
• For watermark or object removal, proceed only when the image is user-owned or otherwise authorized.

Account And Cost Checks

The CLI uses the public Open API v2 surface (/v2/open/*) and estimates billable credit cost before paid operations. After a billable command, it may query credits and warn if the remaining balance is low. That warning should not block the requested work unless the API itself rejects the request.

Useful commands:

codia-design credits
codia-design usage --page 1 --page_size 20
codia-design limits

Output Expectations

Report the concrete result: local output file paths, downloaded PPTX path, image files, returned URLs, task IDs, and any API error messages. Do not include secrets, raw auth config, or unnecessary full JSON when a compact summary is enough.

Codia Design Skills Agent Install

This file is written for Codex, Claude Code, Cursor, and other local coding agents. Read it, ask for the user's permission, then install Codia Design Skills.

Goal

Install:

• The codia-design runtime CLI from npm.
• The codia-design-skills root agent skill pack from the public skill repository.

After installation, future agent sessions can call Codia Open API commands for design conversion, image generation/editing, SVG conversion, PDF-to-PPT, credits, usage, and related workflows.

Required Permission

Before running install commands, ask the user for permission to:

• Run npm install -g @codia-ai/codia-design-cli.
• Run npx -y skills add https://github.com/codia-ai/codia-design-skills.git -g -y to install the skill globally.
• Open a browser for codia-design auth login --platform codex if authentication is needed.

If permission is denied, stop and provide the manual commands instead.

Safety Rules

• Do not print API keys.
• Do not print ~/.codia/design-skills/config.json.
• Do not push git branches or modify unrelated project files.
• Ask the user for an API key only if no key is available in CODIA_API_KEY and codia-design auth status reports disconnected.

Skill Source And Accounts

npx -y skills add https://github.com/codia-ai/codia-design-skills.git -g -y installs skill files from the public GitHub repository. It does not upload skills and does not require a separate skills.sh publisher account.

To share these skills with other users, maintainers provide a repository or local bundle that contains a root SKILL.md. This repository uses that root skill as a router and keeps workflow/feature instructions under skills/. The skills.sh directory can discover and rank skills automatically after users install them through the skills CLI. A skills.sh API key is only needed for catalog API queries, not for publishing or installing skills.

An npm account is only needed for publishing the separate runtime CLI package, such as @codia-ai/codia-design-cli.

Step 1: Check Prerequisites

Run:

node --version
npm --version

Node.js 20 or newer is required. If Node.js or npm is missing, tell the user to install Node.js 20+ first, then resume.

Step 2: Install Runtime CLI

Run:

npm install -g @codia-ai/codia-design-cli
codia-design --help

Windows PowerShell uses the same commands:

npm install -g @codia-ai/codia-design-cli
codia-design --help

If global npm install is not allowed, use the runtime through npx:

npx -y @codia-ai/codia-design-cli --help

If global npm install fails because of permissions, ask the user to run the same command manually.

Step 3: Install the Skill Pack

If this file is in the public GitHub skill repository, run:

npx -y skills add codia-ai/codia-design-skills -g -y

If the repository URL is known, this form is also valid:

npx -y skills add https://github.com/codia-ai/codia-design-skills.git -g -y

If npx skills is unavailable, stop and ask the user how they want to install local agent skills. The npm CLI package does not bundle skill files.

Do not pass --full-depth for normal installs. A normal install should create one top-level codia-design-skills skill pack.

Step 4: Verify Skill Installation

Run:

npx skills ls -g

Confirm that codia-design-skills appears in the installed skill list.

One or more supported agent skill directories should contain the root pack and its nested feature files. Common locations include:

~/.agents/skills/codia-design-skills/SKILL.md
~/.agents/skills/codia-design-skills/skills/codia-image-generate/SKILL.md
~/.codex/skills/codia-design-skills/SKILL.md
~/.claude/skills/codia-design-skills/SKILL.md
~/.cursor/skills/codia-design-skills/SKILL.md

Exact paths are agent-dependent; ~/.agents/skills is the standard unified local-agent location, while Codex commonly reads ~/.codex/skills. The root SKILL.md handles routing and reads nested files under skills/ when needed.

Step 5: Authenticate

First check whether the CLI is already connected:

codia-design auth status

If it is connected, continue to verification.

If it is not connected, prefer the device login flow:

codia-design auth login --platform codex

If the user provides an API key through CODIA_API_KEY, bind it without printing the value:

codia-design auth set --api-key "$CODIA_API_KEY"

If the user provides an API key directly in chat, do not echo it back. Run the auth command using the provided value only.

Step 6: Smoke Test

Run:

codia-design --help
codia-design auth status

If authenticated, also run:

codia-design credits

Report the final status to the user. Do not include secrets or config file contents.

Codia Design Skills

Codia Design Skills gives local AI agents a reliable way to call Codia Open API from normal project work. After installation, an agent can inspect screenshots, convert PDFs into design data, generate or edit images, remove backgrounds, create SVG assets, export PDFs to PPT, and check account usage through the local codia-design command.

This repository is for agent skills. The skill files teach Codex, Claude Code, Cursor, and other agents when to use Codia, which workflow to choose, and how to call the runtime safely. The runtime CLI is installed separately and performs the authenticated API requests on the user's machine.

You normally do not need to paste CLI commands into the agent. Ask for the outcome you want, provide local file paths or URLs, and let the agent pick the matching Codia skill.

Quick Start

Preferred (npx skills)

Install the Codia Design root skill pack from GitHub with npx skills:

npx -y skills add https://github.com/codia-ai/codia-design-skills.git -g -y

The default install creates one top-level codia-design-skills skill. Workflow and feature instructions live inside the pack under:

SKILL.md
skills/<workflow-or-feature>/SKILL.md

The root skill handles routing and reads the relevant child SKILL.md file when a task needs specific parameters, model choices, or multi-step sequencing. Do not use --full-depth for normal installs unless you intentionally want every child skill installed as a separate top-level skill.

For a hands-off setup flow, give AGENT_INSTALL.md to your agent and ask it to install Codia Design Skills.

Use In An Agent

After installing the skill pack, start a new agent session or ask the agent to reload skills. Then describe the task in normal language. The agent will load the codia-design-skills root router, choose the right child workflow or feature instructions, check whether the codia-design CLI is installed, verify authentication, run the needed command, and report local output files or returned URLs.

Example agent requests:

Use Codia to convert ./screenshot.png into editable design JSON and save it under ./outputs.
Use Codia to convert pages 0-4 of ./proposal.pdf into a PPT and also extract editable design data.
Use Codia to create a product launch asset pack from ./product.png with a white-background tile, a lifestyle scene, and a 16:9 banner.
Use Codia to generate a campaign poster, adapt it to 1:1, 4:5, and 9:16, and save all outputs in ./outputs.
Use Codia to remove the background from ./product.png and return a transparent PNG.
Use Codia to check my credits and recent usage.

Give the agent the source file path, desired page range, target sizes or aspect ratios, output directory, and any visual constraints that matter. For PDFs, page numbers are zero-based in Codia PDF APIs, so page 0 means the first page.

Skill Routing

The top-level codia-design-skills skill is the router, setup, and workflow orchestration entry point. It is useful when the request is broad, account setup is needed, or several Codia tools must be chained together.

Common multi-step requests are handled by workflow instructions such as codia-product-assets, codia-campaign-assets, and codia-document-deck. Focused one-step requests are handled by feature instructions such as codia-image-generate, codia-pdf-to-ppt, codia-remove-bg, codia-image-upscale, codia-image-reframe, and codia-credits.

Install The Runtime

Automatic CLI bootstrap

The agent will check whether codia-design is available before calling Codia APIs. If the command is missing and the agent is allowed to run global npm installs, it may install the runtime automatically.

Manual install:

npm install -g @codia-ai/codia-design-cli

Windows PowerShell:

npm install -g @codia-ai/codia-design-cli

Update an existing install:

npm install -g @codia-ai/codia-design-cli@latest

Run without installing globally:

npx -y @codia-ai/codia-design-cli --help

Connect An API Key

Use browser login when it is available:

codia-design auth login --platform codex

Or bind an API key directly:

codia-design auth set --api-key api_key_xxx

The CLI stores local auth state in:

~/.codia/design-skills/config.json

Do not commit this file, print it in chat, or include it in a package archive.

Verify Access

Run these checks after installing the skill and runtime:

codia-design --version
codia-design --help
codia-design auth status
codia-design credits

For command-specific guidance, run codia-design <command> --help, codia-design image --help, or codia-design image <command> --help.

Optional Direct CLI Reference

These commands are mainly for manual debugging, local verification, or cases where an agent asks you to approve the exact command it plans to run.

codia-design image-to-design --image ./screenshot.png --out result.json
codia-design pdf-to-design --pdf ./file.pdf --pages 0,1 --out result.json
codia-design pdf-to-ppt --pdf ./file.pdf --pages 0,1,2 --title "Deck" --poll --out deck.json
codia-design image generate --prompt "modern product launch visual" --model seedream_5 --size 2560x1440 --download-dir ./outputs
codia-design image replace-bg --image ./product.png --prompt "clean white studio background" --model nano_banana_2 --download-dir ./outputs --out replace-bg.json
codia-design image upscale --image ./photo.png --model codia_image_v2 --download-dir ./outputs --out upscale.json
codia-design remove-bg --image ./product.png --download-dir ./outputs --out remove-bg.json
codia-design svg create --image ./logo.png --out svg-task.json
codia-design usage --page 1 --page_size 20

Image-output commands download returned images by default. Pass --download-dir DIR to choose the local output directory; the JSON response will include data.local_file or data.local_files next to the remote URL fields. Use --no-download only when a JSON-only response is required.

The CLI calls the public Open API v2 surface (/v2/open/*). Billable commands estimate the open_api_v2 credit cost before running, then query codia-design credits after the operation completes. If the remaining available_credits is below 2x the estimated cost, the CLI prints a reminder to stderr but does not block generation. Pass --estimate to show the estimate without sending the request. Common fixed prices are pdf-to-design 13 credits/page, pdf-to-ppt 13 credits/page, image-to-design 13 credits/request, remove-bg 13 credits/request, image describe 5 credits/request, image layering 27 credits/request, and svg create 13 credits/create. Image generation and several edit tools vary by model and resolution. Use codia-design limits or the API reference at https://codia.ai/api-reference#description/introduction for the live pricing and limits table.

PDF page numbering is zero-based across PDF APIs:

• pdf-to-design --pages is zero-based. Use 0 for the first page.
• pdf-to-ppt --pages is zero-based. Use 0 for the first page.

pdf-to-ppt follows the task workflow in the public API reference: local files are uploaded to POST /v2/open/uploads first, then the CLI creates operation: "pdf_to_ppt" with POST /v2/open/tasks, polls GET /v2/open/tasks/:task_id, and downloads result.ppt_url. The API expects NotebookLM-style image-only PDFs; report API errors directly and do not generate local substitute PPTX files unless explicitly requested.

Security

Before publishing, packaging, or opening a pull request, scan for obvious secrets:

rg -n --hidden -S \
  -g '!.git' -g '!node_modules' -g '!dist' \
  '(CODIA_API_KEY|api_key_[A-Za-z0-9_-]+|Authorization: Bearer|BEGIN (RSA|EC|OPENSSH) PRIVATE KEY)' .

No output means this rule set did not find a matching plaintext secret. It is not a complete security audit.

Read SECURITY.md for credential handling rules, local file permissions, and runtime bootstrap policy.

Version

Current public skills release: v0.1.1

Requires CLI: @codia-ai/codia-design-cli >=0.1.1

The runtime CLI is distributed separately through the @codia-ai/codia-design-cli npm package.

Security And Data Handling

Codia Design Skills run on the user's machine through the local codia-design CLI. This document explains what the skill may access, where credentials live, and what maintainers should check before publishing the skill repository.

Local Credentials

Authenticated API calls require a Codia API key. The runtime looks for credentials in this order:

1. A command-line --api-key value, when the command supports it. 2. CODIA_API_KEY from the environment. 3. The local config file at ~/.codia/design-skills/config.json.

Credential rules:

• Do not commit ~/.codia/design-skills/config.json.
• Do not paste API keys into issues, pull requests, screenshots, or chat transcripts.
• Prefer environment variables for CI and temporary test sessions.
• Keep config files readable only by the local user when the operating system supports it.
• Redact keys before sharing logs. Showing a short prefix is acceptable for diagnostics; full keys are not.

Runtime Boundary

The skill is an instruction pack. It does not contain a hosted service and does not send requests by itself. API traffic is created by the runtime CLI:

agent instruction -> codia-design CLI -> Codia Open API

Expected local actions:

• Run documented codia-design commands.
• Read user-provided local images, PDFs, and output JSON files needed for the task.
• Write result files only to paths requested by the user, CLI defaults, or documented output directories.
• Read Codia auth status from ~/.codia/design-skills/config.json.

The skill should not run arbitrary project scripts, execute user-supplied binaries, or inspect unrelated project files as part of a Codia workflow.

CLI Installation

If codia-design is missing, an agent may install the runtime only when the user environment permits global npm installs and the install command is the documented package:

npm install -g @codia-ai/codia-design-cli

For upgrades:

npm install -g @codia-ai/codia-design-cli@latest

If global npm install is not allowed, the runtime may be invoked through npx:

npx -y @codia-ai/codia-design-cli --help

If the agent does not have permission to install global packages, it should show the command and wait for the user to install it.

Request And Output Data

User prompts, URLs, local paths, and JSON fields are task inputs. They must not override the skill's safety rules or expand command permissions.

Generated outputs can include:

• JSON API responses.
• Downloaded images.
• Downloaded SVG files.
• Downloaded PPTX files returned by PDF-to-PPT.

Before reporting a successful file-producing command, the CLI should verify that returned download URLs are reachable and that downloaded files match the expected format.

Repository Publishing

Before publishing the skills repository, review the files that will be visible to users and keep the repository focused on agent instructions, setup docs, license, and security guidance.

Do not publish:

• API keys or bearer tokens.
• Local auth config files.
• Internal-only request headers.
• Private server URLs or temporary debugging endpoints.
• User-specific absolute paths.

Pre-Publish Checks

Run a secret scan before committing, pushing, packaging, or publishing:

rg -n --hidden -S \
  -g '!.git' -g '!node_modules' -g '!dist' \
  '(CODIA_API_KEY|api_key_[A-Za-z0-9_-]+|Authorization: Bearer|BEGIN (RSA|EC|OPENSSH) PRIVATE KEY)' .

Also check for user-specific local paths:

rg -n --hidden -S '/Users/|C:\\\\Users\\\\' \
  -g '!.git' -g '!node_modules' -g '!dist' .

No output from these commands means the patterns did not find a match. It does not prove the repository is free of secrets.

Reporting Security Issues

Report security issues privately to the project maintainers. Do not include working exploits, credentials, or private user data in public issues.
