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 5.1 | $0.00024 | $0.00751 |
| Opus 5.5 | $0.00010 | $0.00300 |
| Sonnet 5.5 | $0.00005 | $0.00150 |
| Haiku 4.5 | $0.00002 | $0.00075 |
Grade A, and why
android-serialization-offline-sync 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 1mo ago.
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.

Android Serialization Offline Sync
When To Use
- Use this skill when the request is about: offline sync android, serialization model mapping android, conflict resolution android cache.
- Primary outcome: Coordinate serialization, caching, conflict handling, and offline-first sync flows in Android apps.
- Handoff skills when the scope expands:
android-networking-retrofit-okhttpandroid-room-database
Workflow
- Confirm the data source, persistence boundary, sync model, and device capability involved.
- Model contracts explicitly before wiring network, storage, media, or background APIs.
- Apply the recommended AndroidX or platform pattern with migration-safe defaults.
- Validate offline, retry, and process death behavior against the sample apps and scenarios.
- Escalate security, performance, or release risk to the linked supporting skills when needed.
Guardrails
- Prefer typed models and explicit serializers over ad-hoc maps or bundles.
- Keep background work idempotent and cancellation-aware.
- Do not leak storage, media, or networking details into presentation code.
- Treat user data durability, privacy, and migration paths as part of the implementation.
Anti-Patterns
- Blocking the main thread with disk or network calls.
- Treating retryable sync failures as terminal user-facing errors.
- Mixing cache models and wire models without a mapping layer.
- Requesting broad storage or notification capabilities when a narrower API exists.
Examples
Happy path
- Scenario: Sync local task edits to a remote model with explicit mapping.
- Command:
cd examples/orbittasks-compose && ./gradlew :app:testDebugUnitTest
Edge case
- Scenario: Recover when remote and local timestamps disagree after offline edits.
- Command:
cd examples/orbittasks-xml && ./gradlew :app:testDebugUnitTest
Failure recovery
- Scenario: Keep sync/serialization work separate from pure networking or Room-only requests.
- Command:
python3 scripts/eval_triggers.py --skill android-serialization-offline-sync
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.

android-serialization-offline-sync is a skill published in the GitHub repository krutikJain/android-agent-skills (14 stars, last pushed 7mo ago), licensed MIT. It adds 24 tokens to every session and 751 once invoked, about $0.0001 per session on Opus 5.5. 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.
