Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00083 | $0.01347 |
| Opus 5 | $0.00042 | $0.00674 |
| Sonnet 5 | $0.00017 | $0.00269 |
| Haiku 4.5 | $0.00008 | $0.00135 |
Grade A, and why
video-codec-processing-workflow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Video Codec Processing Workflow
Purpose
Guide low-level Apple video encode, decode, and pixel-buffer work while keeping ordinary reader/writer/export pipelines with AVFoundation and exact compressed sample timing with Core Media.
When To Use
- Use for
VTCompressionSession,VTDecompressionSession, codec properties, hardware selection, compressed callbacks, pixel-buffer pools, color/HDR attachments, multipass, latency, or codecOSStatusrepair. - Recommend
avfoundation-media-pipeline-workflowwhenAVAssetReader,AVAssetWriter, export, or general transcode behavior expresses the requirement. - Recommend
coremedia-timing-samplebuffer-workflowwhen timestamps, format descriptions, sample dependencies, or synchronization are the primary bug.
Single-Path Workflow
- Classify the request:
- compression or decompression
- real-time or offline encode
- hardware encoder/decoder selection
- bitrate, keyframes, reordering, latency, profile, or entropy policy
- multipass encoding
- pixel-buffer allocation, pool, planes, or Metal/IOSurface interop
- compressed sample, parameter-set, color/HDR, or attachment repair
- lifecycle, callback,
OSStatus, or performance diagnosis
- Apply the Apple docs gate:
- read current VideoToolbox, Core Video, and Core Media documentation for the codec and platform
- state the documented behavior relied on
- apply
../../shared/references/apple-media-type-ownership.md - prefer AVFoundation unless the requirement needs low-level codec selection, latency, per-frame control, hardware policy, or callback access
- Establish the media contract:
- codec, dimensions, profile/level, frame rate, timescale, pixel format, color primaries, transfer function, YCbCr matrix, dynamic range, alpha, bitrate, latency, and destination
- input/output
CMVideoFormatDescription, parameter sets,CMSampleBuffer,CVPixelBuffer, attachments, and timing ownership
- Configure and prepare one session owner:
- inspect encoder/decoder availability and supported property dictionaries
- create the session with explicit specifications and image-buffer attributes
- set only supported properties and check every
OSStatus - prepare the compression session when appropriate
- Submit and drain:
- preserve frame identity, presentation timestamp, duration, and source lifetime
- handle asynchronous callback status, info flags, delayed frames, dropped frames, dependencies, and output format changes
- complete/finish delayed frames, end passes, wait for asynchronous work where required, then invalidate exactly once
- Return the documented behavior, AVFoundation-versus-VideoToolbox decision, capability evidence, session and buffer contract, color/timing policy, diagnostics, profiling evidence, and handoffs.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

video-codec-processing-workflow is a skill published in the GitHub repository gaelic-ghost/socket (7 stars, last pushed 9d ago), licensed Apache-2.0. It adds 83 tokens to every session and 1,347 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
