What it does

Ccap is an agent skill from wysaid/CameraCapture. Install or use the ccap CLI for camera capture, webcam inspection, device listing, frame capture, and video metadata. Use when you need to work with CameraCapture on macOS, Linux, or Windows, especially for listing devices, checking device capabilities, capturing frames, inspecting video files, or choosing between existing install, Homebrew, source build, and release-binary fallback.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `PUBLISHING.md`, `references/commands.md` and `references/install.md`).

It sits in Mobile. It works with Linux, Homebrew, macOS and iOS. The repository describes itself as: ccap (C)amera(CAP)ture is a simple and easy-to-use C/C++ camera capture library designed to provide you with simple and efficient camera data access. It currently supports… The licence is MIT.

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

Determine whether the task is installation, device inspection, capture, or video inspection.
Reuse an existing ccap binary if one is already available.
If installation is needed, follow the environment decision tree instead of inventing a platform-specific path.
Prefer a JSON-capable command when the task can be solved with structured output.
Verify the selected workflow with a minimal command before attempting larger capture or preview runs.
If the environment blocks the task, report the exact blocker: missing binary, missing permission, no device, unsupported platform path, or…

What it can do on your machine

Read from SKILL.md and the folder at commit d187600. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ccap loads about 1.4k tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 98 tokens; SKILL.md has 665 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~98
When it runs · the whole SKILL.md, loaded when a task matches: ~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~2.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

ccap

Use this skill when an agent needs to install or operate ccap as a practical vision-input CLI.

This skill is packaged as a standalone skill folder so it can be reused as a standard agent skill entry.

Typical Triggers

Use this skill when the user asks for things like:

"list my cameras"
"show device capabilities"
"capture one frame from webcam 0"
"record 5 seconds from webcam 0"
"save webcam stream to mp4"
"inspect this mp4"
"install ccap on this machine"
"use CameraCapture from the CLI"

What This Skill Is For

Installing ccap on the current machine
Reusing an existing ccap installation when already available
Building ccap from source when local development tools exist
Falling back to a release binary when no build toolchain is available but a matching release asset exists
Listing camera devices
Inspecting device capabilities
Capturing one or more frames with the CLI
Recording camera streams to MP4/MOV with the CLI
Reading video metadata

What This Skill Is Not For

Editing CameraCapture library internals
Assuming camera access permission is already granted
Assuming preview is safe in CI, SSH, or headless environments
Assuming all platforms support video-file playback equally

Default Behavior

Prefer the ccap CLI over internal source files.
Prefer --json when the command supports it.
Prefer non-preview workflows unless the task explicitly needs preview.
Treat camera devices, permissions, GUI support, and backend support as environment-dependent.

Procedure

Determine whether the task is installation, device inspection, capture, or video inspection.
Reuse an existing ccap binary if one is already available.
If installation is needed, follow the environment decision tree instead of inventing a platform-specific path.
Prefer a JSON-capable command when the task can be solved with structured output.
Verify the selected workflow with a minimal command before attempting larger capture or preview runs.
If the environment blocks the task, report the exact blocker: missing binary, missing permission, no device, unsupported platform path, or unavailable release asset.

Environment Decision Tree

Check whether ccap is already installed and runnable.
If running on macOS and brew exists, prefer Homebrew installation.
Otherwise, if CMake and a compiler are available, build from source.
Otherwise, if network access is available and a matching GitHub Release asset exists, download and use that binary.
If none of the above is possible, stop and report the missing prerequisite instead of guessing.

See installation details.

Stable Command Patterns

Use these first before improvising:

List devices: ccap --list-devices --json
Device info: ccap --device-info 0 --json
Video info: ccap -i /path/to/video.mp4 --json
Capture one frame: ccap -d 0 -c 1 -o ./captures
Record camera stream: ccap -d 0 --record ./camera_capture.mp4 --timeout 5
Capture one frame from a named device: ccap -d "OBS Virtual Camera" -c 1 -o ./captures

More examples and fallback notes are in command reference.

Operational Rules

If a command supports --json, prefer parsing JSON over scraping text output.
If device enumeration succeeds but opening the device fails, treat that as a permission or device-access issue.
If camera permission is denied, report the authorization requirement instead of repeated retries.
If there is no camera device, consider a video-file workflow if that satisfies the task.
If the environment is headless or remote, do not enable preview by default.
If video playback is unsupported on the current platform or build, report it explicitly.
If recording is requested, verify writer support first (CCAP_ENABLE_VIDEO_WRITER=ON and supported platform: Windows/macOS).
--record is camera-mode only. If input is a video file (-i), report that recording is ignored.

Response Expectations

Prefer reporting the exact command used.
Prefer reporting whether the output is structured JSON or plain text.
If installation was performed, state which path was chosen: existing binary, Homebrew, source build, or release binary.
If the task failed, report the smallest actionable next step instead of a vague failure summary.

Verification

After installation or selection of an existing binary, verify with one or more of:

bash

ccap --version
ccap --list-devices
ccap --list-devices --json
ccap -i /path/to/video.mp4 --json
