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 | $0.06095 | $0.06095 |
| Opus 5.5 | $0.02438 | $0.02438 |
| Sonnet 5.5 | $0.01219 | $0.01219 |
| Haiku 4.5 | $0.00609 | $0.00609 |
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 1mo 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.
Quick Reference
Build & Test Commands
| Command | Description |
|---|---|
./bin/mise run build |
Debug build |
./bin/mise run build:release |
Release build (no WMO) + MLX metallib |
./bin/mise run test |
Run all tests |
./bin/mise run test:filter <name> |
Run filtered tests |
./bin/mise run lint |
Run linters |
./bin/mise run format |
Format all code |
The tasks and CI use swift build --build-system native. The Swift 6.4 default build
system needs MetalToolchain for the .metal sources, and it does not link CNumKong.o.

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 1mo ago), licensed MIT. It adds 6,095 tokens to every session, about $0.0244 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.
