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 | $0.01266 | $0.01266 |
| Opus 5.5 | $0.00506 | $0.00506 |
| Sonnet 5.5 | $0.00253 | $0.00253 |
| Haiku 4.5 | $0.00127 | $0.00127 |
Grade A, and why
AgentShot 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 2mo 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.

AgentShot Agent Guide
This file is for AI coding agents working on AgentShot.
Project Summary
AgentShot is a local-first screenshot bridge for terminal AI agents. It helps users capture or copy a screenshot, save it as a local image file, render an AI-tool-specific prompt that references the image path, and copy that prompt to the clipboard.
The primary user workflow is:
install AgentShot -> daemon watches clipboard -> user takes screenshot -> AgentShot saves image and copies prompt -> user pastes into Claude Code, Codex CLI, or another terminal AI tool
AgentShot should not upload screenshots, call AI APIs, or inject text into terminal windows by default.
Product Direction
Primary distribution is npm:
npm install -g jcagentshot
The package uses postinstall only to print daemon setup guidance. It must not start background processes or register startup services during package installation.
Current product phases:
- Robust local screenshot bridge.
- Resident startup daemon by default.
- Read-only AI session detection for future explicit injection workflows.
Direct terminal injection is not a default behavior. Keep the safe default as "copy prompt to clipboard, user pastes manually".
Tech Stack
- Runtime: Node.js 18+
- Module system: ESM
- CLI entrypoint:
bin/agentshot.js - Tests: Node built-in test runner
- Package manager: npm
- Platforms: Windows and macOS first, limited Linux clipboard fallback
- No runtime npm dependencies currently

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.
