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 | $0.00620 | $0.00620 |
| Opus 5.5 | $0.00248 | $0.00248 |
| Sonnet 5.5 | $0.00124 | $0.00124 |
| Haiku 4.5 | $0.00062 | $0.00062 |
Grade A, and why
hexgate 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 34 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hexgate — Agent Instructions
Tech Stack
- Python ≥ 3.13 (
uv), FastAPI (platform/api/), ClickHouse (Docker), Redpanda (Docker, Kafka-protocol-compatible; dev broker inplatform/docker-compose.yml, deployed as the OTLP span buffer inplatform/docker-compose.deploy.yml) - React, Vite, pnpm (
platform/dashboard/) - Ruff (Python). WASM via
wasmtime.
Cross-package
After you make changes across multiple packages, run: make check-all # all packages
Repo Layout

AI Constraints (CRITICAL)
- NEVER fabricate code examples, config snippets, or file contents. If unknown, read the file first.
- Verify third-party or config behavior against actual files in this repo before generating code.
Rules & Constants
- Branches:
{initials}/{type}/{short_description}(e.g.,vl/feat/web_search) - Commits:
type(scope): description(lowercase, imperative, no period). Scopes:platform-api,platform-scripts,dashboard,sdk,cli,clickhouse,redpanda,collector,evals,mcp. Types:feat,fix,docs,build,refactor,test. - Envs: All prefixed with
HEXGATE_. Never commit private keys.
Agent Instruction Files
- These files follow AGENTS.md. A nested one adds to this file rather than replacing it: Claude loads
platform/api/AGENTS.mdon top of this one once it reads a file underplatform/api/. - There is no precedence rule between them — if two rules contradict, Claude may pick either — so keep them from disagreeing rather than relying on the nearer file to win.
- Each
AGENTS.mdhas aCLAUDE.mdbeside it holding one line,@AGENTS.md. Claude Code stops reading everyAGENTS.mdin a repo as soon as anyCLAUDE.mdexists at or above the working directory, so the pointers are what keep the nested files loading. Put Claude-specific notes under the import, not inAGENTS.md. - Repo skills live in
.claude/skills/. That path is Claude-specific and deliberate: nothing under.agents/is read.
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.

hexgate AGENTS.md is an instructions file published in the GitHub repository HexamindOrganisation/hexgate (23 stars, last pushed today), licensed MIT. It adds 620 tokens to every session, about $0.0025 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 2026-09-26.
