Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01736 | $0.01736 |
| Opus 5 | $0.00868 | $0.00868 |
| Sonnet 5 | $0.00347 | $0.00347 |
| Haiku 4.5 | $0.00174 | $0.00174 |
Grade A, and why
GhostLine 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 2d 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 — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project summary
GhostLine is a model-agnostic, LLM-fueled vishing operative for authorized security assessments. It places outbound PSTN calls via Twilio Media Streams, transcribes target speech with Deepgram, generates a social-engineered reply through the OpenAI Agents SDK (backed by any LLM via LiteLLM), synthesizes the reply with ElevenLabs (optionally a cloned voice), and streams µ-law audio back to Twilio.
Ethical guardrail: GhostLine must only be used against targets covered by a signed Rules of Engagement. Never weaken the Guardrails in src/ghostline/agent/ or the consent disclosures in README.md.
Tech stack
- Project / deps: uv-managed Python 3.12 (
pyproject.toml,uv.lock). Norequirements.txt, no venv hand-rolling. - Layout:
src/layout. Package isghostlineundersrc/ghostline/. - LLM runtime: OpenAI Agents SDK (
openai-agents) with the LiteLLM adapter so the LLM provider is swappable viaLITELLM_MODELenv var. - Web: FastAPI + Uvicorn. One WS endpoint (
/twilio) consumes Twilio Media Stream frames. - Async I/O:
aiohttpfor Deepgram WSS and ElevenLabs HTTP.aiosqlitefor persistence. No sync I/O in the call hot path. - DSP: numpy + scipy.
audioopis gone (deprecated in 3.13); µ-law encoding is implemented in pure numpy. - Telephony:
twilio(REST) +pyngrok(tunnel). - CLI: Typer. Entrypoint:
ghostline(see[project.scripts]).

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.

GhostLine AGENTS.md is an instructions file published in the GitHub repository mbhatt1/GhostLine (127 stars, last pushed 1mo ago), licensed MIT. It adds 1,736 tokens to every session, about $0.0087 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 2026-08-30.
