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 | $0.00048 | $0.00904 |
| Opus 5 | $0.00024 | $0.00452 |
| Sonnet 5 | $0.00010 | $0.00181 |
| Haiku 4.5 | $0.00005 | $0.00090 |
Grade A, and why
agp-9-upgrade 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 12d 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.
This is a copy
94% identical to agp-9-upgrade — 16 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Migration guide
See the AGP 9 migration guide for the major changes, many breaking, in AGP 9 compared to AGP 8.
Requirements
If the user requests to update or migrate to AGP 9, first check the AGP version used in the project. If it is lower than 9, stop and ask the user to run the AGP Upgrade Assistant in Android Studio to update to the latest stable version of AGP, and confirm when done. The user may also request that this requirement be skipped; if this is the case, you should update the version of AGP to the latest stable version as part of the AGP 9 migration. See the AGP 9 migration guide for how to do this.
Each version of AGP has its own set of compatibilities with other tools, such as Gradle, JDK, and Kotlin. The release notes for each of these versions will include a Compatibility table indicating the minimum versions for these tools.
Do not use this skill for KMP projects, as they are unsupported.
Steps
If AGP is already at 9 or higher, then do the following:
Step 1: Update dependencies
If KSP (com.google.devtools.ksp) is used in the project, ensure it is on
version 2.3.6 or higher.
If Hilt is used in the project, ensure it is on version 2.59.2 or higher.
Step 2: Migrate to built-in Kotlin.
See the guide for detailed information.
Step 3. Migrate to the new AGP DSL.
See the guide for detailed information.
See also gradle-recipes for examples on how to migrate old code to code that is compatible with AGP 9 and the new DSL.
Step 4. Migrate kapt to KSP or legacy-kapt
If KSP (com.google.devtools.ksp) or kapt (org.jetbrains.kotlin.kapt) are
used in the project, KSP, kapt, and legacy-kapt
for detailed migration steps.
What ships with it
6 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.
