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 | $0.01830 | $0.01830 |
| Opus 5 | $0.00915 | $0.00915 |
| Sonnet 5 | $0.00366 | $0.00366 |
| Haiku 4.5 | $0.00183 | $0.00183 |
Grade D, and why
SwarmAI security-coding-baseline.md scanned grade D with 4 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 yesterday.
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.

Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.

The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Security Coding Baseline
Security guardrails for writing code in SwarmAI, aligned with industry practice (OWASP Top 10, OWASP Top 10 for LLM / Agentic Applications), filtered to what a local desktop AI agent actually needs.
Threat model: single-user local app, but the agent has real tool access (bash, filesystem, MCP servers) and ingests untrusted external content (GitHub, RSS, web fetch, chat, MCP tool responses). Treat every external byte as hostile.
Part A — Secure Coding
These are hard rules. A violation is a review blocker, not a nit.
A1. No unsafe deserialization / code execution
- NEVER
pickle.load/loads,yaml.load()(useyaml.safe_load),eval(),exec(),torch.load(untrusted), orjoblib.load(untrusted)on data that crosses a trust boundary (disk written by another process, network, MCP response, model file). - ML/embedding models: use
weights_only=True/safetensors/ framework safe-loaders. Never a raw pickle checkpoint from an external source. - Current state: SwarmAI's own code is clean of these. Keep it that way.
A2. SSRF — validate every outbound URL from untrusted input
Applies to: GitHub community engine, deep-research, web fetch, signal fetchers (RSS/HN), any code that fetches a URL derived from external data.
- Validate against an allowlist of schemes (
httpsonly) and, where possible, host patterns. Reject anything else. - Block requests that resolve to private/loopback/link-local ranges
(
127.0.0.0/8,10/8,172.16/12,192.168/16,169.254.169.254,::1,fc00::/7). Resolve the host and check the IP, don't trust the string. - Do NOT auto-follow redirects into disallowed hosts — re-validate each hop.
- Log every outbound request (URL + origin) so exfil attempts are visible.
A3. No shell=True on non-constant commands
subprocess.run(..., shell=True)is a command-injection surface. Only acceptable when the command string is a hardcoded constant with zero interpolation of external/config values.- Prefer list-form
subprocess.run(["bin", arg1, ...])(no shell parsing). - Known site:
jobs/executor.py::_handle_scriptrunsshell=Trueonjob.config["command"]. Safe ONLY while jobs are author-defined locally. If job configs ever become settable from a channel (chat/remote/API), this becomes RCE — gate the source or drop shell=True 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.

SwarmAI security-coding-baseline.md is an instructions file published in the GitHub repository xg-gh-25/SwarmAI (44 stars, last pushed yesterday), licensed MIT. It adds 1,830 tokens to every session, about $0.0092 per session on Opus 5. A static security scan graded it D with 4 findings (instruction-override phrasing, reaches for credential files, cloud metadata endpoint). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-06.
