open

A command that opens the amnesia memory-management page in a web browser.

In plain words
What is it for?
Run it when you want to open the local memory UI and review saved information.
Why use it?
It gives you a browser interface for reviewing and fixing the memories Claude Code has saved, without needing to work through the command line.

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.

Per session 9 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 232 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

open scanned grade A with 1 finding 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.

What it actually says

Open the amnesia memory UI and hand the user the link. Run each step as a plain foreground command — never append & and never use background execution.

  1. python3 "${CLAUDE_PLUGIN_ROOT}/amnesia.py" --detach — starts the server in its own session so it outlives this one; harmless no-op if it is already running.
  2. curl -s -o /dev/null -w '%{http_code}' --retry 10 --retry-delay 1 --retry-all-errors --max-time 2 http://localhost:8780/ — wait for 200.
  3. open http://localhost:8780 (macOS) or xdg-open http://localhost:8780 (Linux).

Then tell the user, in one sentence, that their memory UI is at http://localhost:8780 — nothing else. Do not summarize what amnesia is or list its features.

Changes

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.

open is a command published in the GitHub repository tiny-cloud-ventures/amnesia (7 stars, last pushed 1mo ago), licensed MIT. It adds 9 tokens to every session and 232 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
