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 | $0.00361 | $0.00361 |
| Opus 5.5 | $0.00144 | $0.00144 |
| Sonnet 5.5 | $0.00072 | $0.00072 |
| Haiku 4.5 | $0.00036 | $0.00036 |
Grade A, and why
solo AGENTS.md 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.
What it actually says
Agent instructions for hiero-ledger/solo
This file orients AI coding agents (GitHub Copilot coding agent and compatible tools). Solo's conventions are defined once and referenced here — do not duplicate them:
- Project overview, commands, architecture, gotchas:
CLAUDE.md - TypeScript style guide (authoritative):
docs/contributing/typescript-code-style.md - Copilot-specific quick rules:
.github/copilot-instructions.md - Enforced lint rules:
eslint.config.mjs— runtask formatbefore committing.
Most-violated rules (read the style guide for the rest)
- No exported functions. Group behavior on a class as
staticmethods; do notexport functionorexport const fn = () => …at module scope. Pure data (constants, types) may be exported. Helpers used by one class becomeprivate staticmembers. (§3.4.5, §10.3.1–§10.3.2; enforced bysolo/no-exported-function.) - One exported class/interface per file, file named in kebab-case matching it. (§3.5) Splitting
interfaces into separate files can introduce circular dependencies — always verify with
npx dpdm --no-warning --no-tree --exit-code circular:1 ./solo.tsafter any such move. import {type X}(inline), explicit type annotations everywhere, no banned abbreviations, SPDX header on every source file.
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.
