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 | $0.00060 | $0.00879 |
| Opus 5 | $0.00030 | $0.00439 |
| Sonnet 5 | $0.00012 | $0.00176 |
| Haiku 4.5 | $0.00006 | $0.00088 |
Grade A, and why
r8-analyzer 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
100% identical to r8-analyzer — 0 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.

The opening of the file, as written. The whole thing — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Core workflow
- [ ] Step 1: Create a file called R8_Configuration_Analysis.md, or reuse if one exists already, to store the output
- [ ] Step 2: Look at the configuration of R8 by looking at build.gradle, build.gradle.kts, gradle.properties in the codebase using references/CONFIGURATION.md as the reference. Inform the developer and add the analysis to the report file
- [ ] Step 3: If the AGP version is less than 9, suggest moving to AGP 9.0 version as AGP 9.0 includes optimizations.
- [ ] Step 4: Look at the proguard files in the codebase and evaluate each keep rule in the following specific order: a. Libraries check : Check rules against references/REDUNDANT-RULES.md. If the app has keep rules targeting libraries - Google, AndroidX, Kotlin, Kotlinx, Room, Gson, Retrofit, inform the user that these are not required and suggest removal of these rules. b. Impact analysis : For the remaining keep rules, assess them based on the impact hierarchy defined in references/KEEP-RULES-IMPACT-HIERARCHY.md. (Note: Do NOT assess the impact of keep rules already covered in the libraries check step).
- [ ] Step 5: Identify subsuming keep rules in the remaining keep rules based on the hierarchy defined in references/KEEP-RULES-IMPACT-HIERARCHY.md and suggest removing the broader keep rules.
- [ ] Step 6: For each remaining keep rule, analyze in detail the code affected by the rule by examining the code and adjacent files to understand why it was written. Look for reflection usage in those packages, and suggest a narrow and specific keep rule for the scenario using references/REFLECTION-GUIDE.md.
- [ ] Step 7: For every keep rule inform concisely and to the point what action needs to be taken - whether the rule needs to be removed/refined.
- If refining the rule, give instructions on finding a narrower and specific keep rule using the /references/REFLECTION-GUIDE.md.
- If removing, provide reasoning on why it needs to be removed.
- [ ] Step 8: After keep analysis, order the keep rule analysis based on the impact to the codebase hierarchy defined in references/KEEP-RULES-IMPACT-HIERARCHY.md
- [ ] Step 9: Advise the user to run tests using UI automator to assess that there is no issue with the suggested changes, concentrating on the packages where keep rules will be affected.
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.

r8-analyzer is a skill published in the GitHub repository tomdwipo/claude-soul (24 stars, last pushed 5d ago), licensed MIT. It adds 60 tokens to every session and 879 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to r8-analyzer, differing in 0 lines, and is treated as a copy.
