What it does

iOS Clut Editor is an agent skill from InternationalColorConsortium/iccDEV. Build, review, and maintain the ios-clut-editor profile and 3D CLUT editing proof-of-concept app without repeating prior iOS review-loop failures.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Prototyping. It works with iOS. The repository describes itself as: iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. The licence is BSD-3-Clause.

When your agent uses it

  • Tasks that involve Prototyping

Example prompts

  • “/ios-clut-editor”

Requirements

  • Pre-approved tools (allowed-tools): bash, read, grep, glob, shell(git:*), shell(gh:*)

Workflow steps

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

  1. Confirm the branch is intended for branch-local grooming, not PR publication.
  2. Read AGENTS.md, .github/copilot-instructions.md,
  3. Review prior iOS examples before editing
  4. Inventory active and suppressed review findings if this branch already has a

What it can do on your machine

Read from SKILL.md and the folder at commit 3c2425d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • bash
    • read
    • grep
    • glob
    • shell(git:*)
    • shell(gh:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • cmake
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    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

iOS Clut Editor loads about 1.1k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 466 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

iOS CLUT Editor Workflow

Use this skill when changing examples/ios-clut-editor/**, its documentation, or its local build helper.

Start Gate

  1. Confirm the branch is intended for branch-local grooming, not PR publication.
  2. Read AGENTS.md, .github/copilot-instructions.md, .github/instructions/build-system.instructions.md, and docs/governance/UPSTREAM_PR_READINESS.md.
  3. Review prior iOS examples before editing: examples/ios-apply-preview, examples/ios-benchapply, Build/AppleMobile, and .github/scripts/iccdev-apple-simulator-smoke.sh.
  4. Inventory active and suppressed review findings if this branch already has a PR. Do not repair comment-by-comment.

Required Invariants

  • IccClutEditorPOC, ICCDEV_CLUTEDITOR_BUNDLE_IDENTIFIER, README commands, and build-ios.sh must refer to the same app and bundle ID.
  • The app consumes matching iOS or Mac Catalyst static core builds; it must not depend on desktop tools, CTest executables, libtiff, wxWidgets, signing files, or generated Xcode output.
  • Keep CMAKE_OSX_DEPLOYMENT_TARGET, CMake Xcode attributes, helper defaults, and README examples aligned.
  • Keep CMM and CLUT application on a background queue and update UIKit only on the main queue.
  • Remove stale Documents/clut-editor-report.json before writing the latest accepted render's report; stale background renders must not overwrite it.
  • Keep simulator launch repeatable with simctl launch --console-pty --terminate-running-process.
  • Keep device launch repeatable with devicectl device process launch --console --terminate-existing --timeout.
  • Keep Mac Catalyst runnable on Apple Silicon Macs through build-ios.sh maccatalyst using a matching Mac Catalyst core archive, not an iOS device or simulator archive.
  • Fail before building device targets when physical-device signing inputs still contain placeholder team or bundle values; unsigned simulator and Mac Catalyst runs must not be blocked by a device-only signing placeholder and should ignore a globally exported placeholder bundle ID.
  • Keep edited-image export available through the native share sheet.
  • Disable report and edited-image sharing while a render is pending so exports cannot use stale controls.
  • Keep the profile-chain CMM interpolation fixed and make the UI selector apply only to the editable CLUT unless the report and docs explicitly say otherwise.
  • Keep the light/dark/system appearance toggle available as an educational visual comparison tool.
  • Keep the compact iPhone layout tuned for visible controls: half-height logo/banner, short action labels, and two-column preview rows; do not regress the current iPad/Mac wide dashboard layout when adjusting phone density.
  • Reused assets must not carry stale sibling-app text such as BENCH or APPLY into CLUT editor source art or generated icons.
  • Doxygen should include the README, .h, and .mm files through INPUT and *.mm in FILE_PATTERNS; do not add EXTENSION_MAPPING = mm=C++.

Validation

Use the smallest complete validation for the changed surface:

bash
git diff --check
cmake --preset apple-ios-simulator-core -S Build/Cmake \
  -DCMAKE_OSX_DEPLOYMENT_TARGET=17.0
cmake --build out/apple-ios-simulator-core --config Release --parallel
examples/ios-clut-editor/build-ios.sh simulator --run-tests
examples/ios-clut-editor/build-ios.sh maccatalyst --run-tests
doxygen .github/ci/doxygen/Doxyfile
test ! -s docs/generated/doxygen-warnings.log

For documentation-only edits, keep the Doxygen and diff checks. For code or helper edits, run the simulator smoke unless unavailable and record the exact skip reason.

Stop Rules

  • Do not push until the local gate covering the current diff passes.
  • Do not request repeated automated reviews for convergence. If a second review cycle finds a new blocker, report review-stop: FAIL - maintainer direction required and stop.
  • Do not add workflow or CTest registration unless a maintainer explicitly requests it.
