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 | $0.05281 | $0.05281 |
| Opus 5 | $0.02641 | $0.02641 |
| Sonnet 5 | $0.01056 | $0.01056 |
| Haiku 4.5 | $0.00528 | $0.00528 |
Grade A, and why
swift-index 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 4d 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.

SwiftIndex - Project Guide
Overview
- Purpose: Semantic code search engine for Swift codebases
- CLI tool + MCP server for AI assistants
- Hybrid search: BM25 + semantic + RRF fusion
- Privacy-first: local embeddings by default
- Platform: Apple Silicon (ARM) only — Intel not supported
- Terminal UI: Use Noora components for CLI progress, spinners, and status steps (avoid custom print-based animations)
Note:
CLAUDE.mdis a symlink toAGENTS.md— editing either file modifies both.

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.

swift-index AGENTS.md is an instructions file published in the GitHub repository alexey1312/swift-index (5 stars, last pushed 5d ago), licensed MIT. It adds 5,281 tokens to every session, about $0.0264 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 2026-08-31.
