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 | $0.00512 | $0.00512 |
| Opus 5.5 | $0.00205 | $0.00205 |
| Sonnet 5.5 | $0.00102 | $0.00102 |
| Haiku 4.5 | $0.00051 | $0.00051 |
Grade A, and why
yantrikdb 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 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
AGENTS.md
Guidance for AI coding agents (Claude Code, Codex, Cursor, and others that read this file) working in this repository.
What this is
YantrikDB is the Rust cognitive-memory engine behind yantrikdb-server and yantrikdb-mcp. Apache-2.0, no CLA, no copyright assignment.
Setup
git clone https://github.com/yantrikos/yantrikdb
cd yantrikdb
cargo test --workspace
A default cargo build has no network code path: the embedder-download
feature is off, so with_default() uses the bundled 64-dim
potion-base-2M. The Python wheel turns that feature on, which is why pip
users get the 256-dim potion-base-8M default instead. If you're touching
embedder code, build both configurations:
cargo build --features embedder-download
cargo build --no-default-features # slim: no bundled embedder at all
Python bindings live in crates/yantrikdb-python (pyo3 + maturin). The
wasm build used by the in-browser demo is crates/yantrikdb-wasm.
Before opening a PR
Both of these must pass — they're also what CI runs:
cargo fmt --all -- --check
cargo clippy --all-targets --all-features --workspace --exclude yantrikdb-python -- --cap-lints warn
cargo test --workspace
cargo fmt --all (no --check) and the clippy line above are the two
that fail most often locally; run them before testing.
Conventions
- One logical change per PR, squash-merged into
main(branch-protected). - Add or extend a test that fails without your change — concurrency and
temporal-decay behavior is easy to break by accident; see
CONCURRENCY.mdfor the invariants. - Describe what you observed, not only what you changed.
- If picking up an existing issue, say so on the issue first.

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.

yantrikdb AGENTS.md is an instructions file published in the GitHub repository yantrikos/yantrikdb (69 stars, last pushed today), licensed Apache-2.0. It adds 512 tokens to every session, about $0.0020 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 2026-10-17.
