## Editorial notes
Asciinema is useful when Claude-adjacent teams need a durable, text-based record of what happened in a terminal without shipping a large screen recording. It can capture a CLI demo, failed reproduction, pair-programming session, or agent run as an asciicast, then replay it locally, publish it to asciinema.org, embed it in docs, or stream the terminal live for reviewers.
## Source notes
- The official docs describe asciinema as a suite of tools for recording, streaming, and sharing terminal sessions.
- The CLI manual describes asciinema CLI as a recorder/client for terminal sessions that stores lightweight `.cast` files, replays them locally, publishes them to an asciinema server, embeds them with the player, or streams sessions live.
- The quick-start docs cover installation from common Linux, macOS, FreeBSD, Cargo, and release-binary paths, plus `rec`, `play`, `upload`, and `stream` workflows.
- The GitHub repository is `asciinema/asciinema`, describes the project as a terminal session recorder, streamer, and player, and is GPL-3.0 licensed.
## Duplicate check
Checked current `content/tools/`, `content/mcp/`, guides, skills, agents, open pull requests, live HeyClaude `llms-full.txt`, and repository-wide content for `Asciinema`, `asciicast`, `asciinema.org`, `docs.asciinema.org`, `github.com/asciinema/asciinema`, `terminal session recorder`, `terminal recording`, `live terminal streaming`, `VHS`, `terminalizer`, `ttyrec`, and `scriptreplay`. Existing AgentOps, Browserless, and Jam entries mention adjacent session replay concepts for agents, browsers, or feedback capture, but no dedicated terminal session recording tools entry, source URL duplicate, or open duplicate PR was found.

| Safety notes | ✓Terminal recordings can capture secrets, prompts, commands, file paths, hostnames, account names, API output, and generated code, so review and redact casts before publishing or embedding them. Live streaming exposes terminal output as it happens; use it only in approved environments and avoid production shells, private repositories, credentials, customer data, and destructive commands. Optional input and environment capture should be configured deliberately because it can record keystrokes, command context, and metadata that are more sensitive than the visible terminal output. | ✓Codex CLI runs as a local agent that can edit files and execute commands on your machine. It supports configurable sandbox and approval modes; keep approvals enabled and review proposed actions before allowing them. Lowering approval or sandbox restrictions lets the agent act more autonomously, increasing the risk of unintended changes. Review generated code and commands before running them against important repositories or systems. | — missing | ✓Crush executes tools and commands; by default it asks for permission before each tool call. The --yolo flag skips all permission prompts; the project warns to be very careful with it, so avoid it on untrusted work. The crush.json config is trusted code — any $(...) in it runs at load time with your shell's privileges, so review config files before use. LSP and MCP servers can read your codebase and influence agent behavior; only connect servers you trust. |
| Privacy notes | ✓Local `.cast` files can contain terminal output, timing data, window size, command metadata, titles, captured environment fields, and optionally keyboard input. Uploading or streaming through asciinema.org sends recordings or live terminal output to the public asciinema service unless visibility and sharing settings are reviewed first. Self-hosted asciinema servers still need access control, retention, backup, log, database, and upload-storage policies for recorded terminal sessions. | ✓Code and prompts are sent to OpenAI to power the agent under your ChatGPT plan or API key. Data handling follows OpenAI's policies for the plan or API you authenticate with; review them before processing sensitive code. API keys and account credentials should be stored securely and never committed to source control. | ✓Aider sends your prompts and the contents of selected repository files to your configured model provider (Anthropic for Claude); a provider API key is required. | ✓Your code context and prompts are transmitted to the LLM provider you configure. API keys are read from environment variables or config files and sent to the configured provider; store them as secrets. Crush records pseudonymous usage metrics tied to a device-specific hash; prompts and responses are never collected. Opt out with CRUSH_DISABLE_METRICS=1 or DO_NOT_TRACK=1. |
