actvt

actvt is a skill for Claude Code from oye-collective/actvt-claude-plugin. It costs 95 tokens per session (956 once invoked), scanned A, original, MIT.

A macOS menu-bar app and local interface for reading Mac health data and coding-agent session history. Coding-agent history can include costs, token use, errors, plan limits, and transcripts, while the local server stays on the Mac.

In plain words
What is it for?
It is for viewing CPU, GPU, memory, network, and temperature data; checking listening ports; and reviewing Claude Code, Codex, pi, and Claude Desktop activity.
Why use it?
It helps answer what the computer and agents are doing without sending the data to a remote server. It also makes earlier sessions easier to inspect.

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

actvt 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (actvt.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Actvt

Actvt is a macOS menu-bar app that watches the Mac and the AI coding agents on it, and serves its data as tools on a local MCP server. pi has no MCP client, so actvt.sh (next to this file) calls those tools with curl. Everything stays on the Mac: the server listens on 127.0.0.1 only.

Calling a tool

./actvt.sh list                                  # every tool, its arguments, what it returns
./actvt.sh agent_recent_activity '{"days":7}'    # one call; arguments are one JSON object
./actvt.sh system_metrics_snapshot               # tools without arguments need none

Run it from this skill's directory, or by its full path. It prints the tool's result (usually JSON) and exits non-zero when the call fails, with the reason on the first line. Run list once when you are unsure of a tool's arguments: the descriptions there are the reference.

Which tool

The user asks Tool
What is the machine doing right now? system_metrics_snapshot, or system_cpu_current, system_gpu_current, system_memory_current, system_network_current, system_thermal_current
How has load changed over the last hour or week? system_metrics_history (trailingMinutes), system_cpu_history, system_gpu_history
What is listening on port N? ports_list
What did my agents cost? agent_recent_activity (per day), agent_metrics_aggregate, agent_project_buckets (per project)
How much of my plan is left? agent_usage_limits
Find the session where... agent_search (text), then agent_session_summary with its compositeKey
Pick up where a session left off agent_resume_session (compositeKey, tailTurns)
Which sessions match a filter? agent_sessions_query, with agent_facet_options for the models, branches and tools to filter on
What keeps failing? agent_error_patterns, agent_recent_error_count
Was it the agent or the machine that stalled? session_machine_context (compositeKey)
Sessions on my other machines agent_remote_sessions

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
