At a glance
Guides API changes in the AppsFlyer Unity plugin across the C# layer and the Android Java and iOS Objective-C bridges, ending with a compatibility-risk report.
- Works in 7 steps: Identify the public C# API being changed… → Trace the full path: C# API →… → Verify whether the API already exists in… → …
- Adding a new method to the AppsFlyer Unity plugin's public API
- SKILL.md covers Goal, Workflow, What to Check and Output Format, plus 1 more section
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
The skill follows an API change from the public C# entry point in AppsFlyer.cs through the platform classes AppsFlyerAndroid.cs and AppsFlyeriOS.cs down to the native bridges. Before editing, the agent checks whether the API already exists in some form and whether the change affects method signatures, argument mapping, callback behavior, event payload shape or Android and iOS parity.
Checks are listed per layer: platform guards and assembly definition boundaries in C#, with the AppsFlyerSDK namespace left unchanged; the Java wrapper's mapping to the Android SDK and its thread safety; and the Objective-C++ wrapper's mapping to the iOS SDK and delegate wiring. Rules include keeping both platforms aligned unless a difference is deliberate, not silently breaking the public C# API, keeping both billing library variants buildable and not stopping at C# when native work is needed.
The agent finishes with a structured report covering a summary, C#, Android, iOS and assembly definition impact, compatibility risk, tests to add or update, and validation steps.
When your agent uses it
- Adding a new method to the AppsFlyer Unity plugin's public API
- Changing callback or event payload behavior across Android and iOS
- Removing or renaming an API without breaking existing integrations
Example prompts
- “Add a method to set a custom user ID in the AppsFlyer Unity plugin on both Android and iOS.”
- “Change the callback payload for in-app events and tell me the compatibility risk.”
- “Check that the iOS bridge matches the Android bridge for the new purchase API.”
Requirements
- The appsflyer-unity-plugin repository
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Identify the public C# API being changed in Assets/AppsFlyer/AppsFlyer.cs.
- Trace the full path: C# API → AppsFlyerAndroid.cs (Android) | AppsFlyeriOS.cs (iOS) → Native bridge
- Verify whether the API already exists in some form.
- Check whether the change affects: method signatures, argument mapping, callback behavior, event payload shape, Android/iOS parity.
- Implement changes in all required layers.
- Check whether tests or example code must be updated.
- Summarize compatibility risk and missing validation.
What it can do on your machine
Read from SKILL.md and the folder at commit 8756add. 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.
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
AppsFlyer Unity Plugin API Change loads about 514 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 235 words of instructions outside code blocks.
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.

- plugin-api-change
- description
- Safely implement or modify a Unity plugin API in the AppsFlyer Unity plugin, including C# API, Android Java bridge, and iOS Objective-C bridge changes.
Plugin API Change
Use this skill when adding, removing, or changing a Unity plugin API.
Goal
Make a safe API change across all plugin layers while preserving backward compatibility where possible.
Workflow
- Identify the public C# API being changed in
Assets/AppsFlyer/AppsFlyer.cs. - Trace the full path: C# API →
AppsFlyerAndroid.cs(Android) |AppsFlyeriOS.cs(iOS) → Native bridge - Verify whether the API already exists in some form.
- Check whether the change affects: method signatures, argument mapping, callback behavior, event payload shape, Android/iOS parity.
- Implement changes in all required layers.
- Check whether tests or example code must be updated.
- Summarize compatibility risk and missing validation.
What to Check
C# layer
AppsFlyer.cs— public API entry pointAppsFlyerAndroid.cs— Android delegation (usesAndroidJavaClass/AndroidJavaObject)AppsFlyeriOS.cs— iOS delegation (uses[DllImport("__Internal")])#if UNITY_IOS/#if UNITY_ANDROIDguards- Assembly definition (
.asmdef) boundaries — do not break - Namespace
AppsFlyerSDK— do not change
Android bridge
AppsFlyerAndroidWrapper.java— Java bridge method- Mapping to AppsFlyer Android SDK
- Threading safety
iOS bridge
AppsFlyeriOSWrapper.mm— Objective-C++ bridge function- Mapping to AppsFlyer iOS SDK
- Delegate/callback wiring
Output Format
Return:
- Summary
- C# API impact
- Android impact
- iOS impact
- Assembly definition impact
- Compatibility risk
- Tests to add or update
- Validation steps
Rules
- Keep Android and iOS behavior aligned unless a platform difference is intentional.
- Do not silently break the public C# API.
- Both billing library variants must remain buildable after the change.
- Do not stop at C#-only changes if native bridge work is required.
