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 | $0.00041 | $0.00222 |
| Opus 5 | $0.00020 | $0.00111 |
| Sonnet 5 | $0.00008 | $0.00044 |
| Haiku 4.5 | $0.00004 | $0.00022 |
Grade A, and why
kmp-tolerant-serialization 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 11d 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.
What it actually says
Tolerant JSON Serialization Skill
Rules for parsing responses and SSE event payloads from unversioned APIs.
Core Rules
-
Configuring Json:
val json = Json { ignoreUnknownKeys = true // Never fail on new server fields isLenient = true encodeDefaults = true coerceInputValues = true } -
Nullable Fields with Defaults:
@Serializable data class ProjectRow( val id: String, val name: String, val gitRepo: String? = null, val framework: String? = null ) -
Sealed Class Polymorphism for SSE Events: Use
@SerialNamediscriminators or event-type router matching.
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.

kmp-tolerant-serialization is a skill published in the GitHub repository kareemessam09/Openship-App (11 stars, last pushed 15d ago), licensed Apache-2.0. It adds 41 tokens to every session and 222 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
