What it does

Motioneyes Animation Debug is an agent skill from edwardsanchez/MotionEyes. Diagnose, fix, or validate SwiftUI animation and scroll behavior by temporarily instrumenting views with MotionEyes, capturing console traces over time, and comparing motion data to user intent or test expectations. Use when users report bugs such as wrong direction, premature fade, timing or easing mismatch, unexpected movement, missing movement, incorrect relative movement between views, scroll jumps, scroll restoration drift, content-offset desynchronization, or when they want to turn MotionEyes traces into…

Its SKILL.md is about 3.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `agents/openai.yaml` and `references/motioneyes-observability-patterns.md`).

It sits in Mobile, covering iOS development. It works with SwiftUI.

When your agent uses it

  • Users report bugs such as wrong direction
  • Easing mismatch
  • Unexpected movement
  • Missing movement

Example prompts

  • “/motioneyes-animation-debug”

Workflow steps

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

  1. Confirm the complaint and expected behavior in measurable terms before instrumentation.
  2. Add only the minimum traces needed to test the complaint.
  3. Prefer XcodeBuildMCP for log capture; fall back to CLI log streaming if MCP is unavailable.
  4. Use semantic trace names that map directly to the user intent.
  5. Preserve all pre-existing MotionEyes instrumentation.
  6. Remove only agent-added MotionEyes imports, modifiers, and metrics after validation.
  7. Re-run after fixes and verify against logs, not assumptions.
  8. Treat continuity, direction, and timing as separate concerns; do not use one heuristic as a proxy for all three.

What it can do on your machine

Read from SKILL.md and the folder at commit 0e9d525. 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

    Shell commands in SKILL.md call:

    • xcrun

    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

Motioneyes Animation Debug loads about 3.2k tokens when it runs, and up to ~4.8k if it reads all its reference files. Until then it costs about 176 tokens; SKILL.md has 1,406 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~176
When it runs · the whole SKILL.md, loaded when a task matches
~3.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.8k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,406 words (~3,186 tokens).

“Use MotionEyes as temporary observability for SwiftUI animation debugging and regression validation. Instrument targeted values and geometry, capture time-series logs, compare observed motion against expected motion, apply fixes or assertions, re-validate, and clean up all agent-added tracing.”
