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 | $0.00029 | $0.00156 |
| Opus 5.5 | $0.00012 | $0.00062 |
| Sonnet 5.5 | $0.00006 | $0.00031 |
| Haiku 4.5 | $0.00003 | $0.00016 |
Grade A, and why
handoff 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 2mo 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

handoff is a skill published in the GitHub repository robiparvez/claude-code-guidelines (2 stars, last pushed 2mo ago), with no licence file. It adds 29 tokens to every session and 156 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 2026-08-31.
Other skills, from other repositories
spring-boot-4-conventions
Spring Framework 7 / Spring Boot 4 idioms and defaults. Use when writing or reviewing controllers, services, configuration, HTTP clients, async/virtual-thread code, or anything touching Spring's programming model.
performance-optimization
Spring Boot 4 / JVM performance work — measure first, then fix. Profiling (async-profiler, JFR, JMH), Micrometer, common Spring antipatterns (N+1, unbounded lists, HikariCP sizing, virtual-thread pinning), caching, GC, and SLO-driven work. Used by /plan for risk callouts and by /review to flag perf regressions.
clarity-over-cleverness
Apply clarity-over-cleverness rewrites — prefer code a junior engineer can read at a glance over compact-but-clever code. Use during /build's simplify step and during /code-simplify (alias "simplify the code"). Never weakens behavior; suite must remain green.
maven-harness-pom
Reference Maven POM fragments for the full harness — Spotless, Checkstyle, SpotBugs, Error Prone, JaCoCo, PIT, OpenAPI generator + diff, OWASP dependency check, Surefire/Failsafe. Use when wiring the harness into a new project or upgrading a brownfield POM.
shipping-and-launch
Pre-deploy hygiene for a Spring Boot 4 feature — verify gates, capture rollback plan, sign off observability, generate release notes, and stage the rollout. Used by /ship after /review approves the diff. The agent never deploys; it produces the plan a human executes.
tdd-red-green-refactor
Strict red/green/refactor/simplify discipline for the /build command. Use when implementing any task in Phase 4. The agent must NOT write production code without a failing test recorded in .tdd-state.json.
