A Slack bot called Mom that can manage its own workspace, run tasks in a Docker sandbox, remember context, and respond to scheduled or immediate events. Slack is a team messaging app, and Docker provides an isolated environment for running software.

Use it to set up or debug the Mom Slack bot, inspect its memory files, manage its sandbox, or create periodic and immediate events.

It brings an agent into Slack while keeping its files, memory, task events, and execution environment organized.

Install

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.

Any agent

npx skills add romiluz13/pi-agent-skills --skill pi-mom

Clone the repo

git clone --depth 1 https://github.com/romiluz13/pi-agent-skills

Made for: Claude Code.

Or install pi-skill, the plugin that ships this one along with the rest of its 11 skills.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00116	$0.01006
Opus 5.5	$0.00046	$0.00402
Sonnet 5.5	$0.00023	$0.00201
Haiku 4.5	$0.00012	$0.00101

Security

Grade A, and why

pi-mom 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.

Pi Mom (Master Of Mischief)

Grounding

pi-mono/packages/mom/README.md — features, workspace setup, memory structure (log.jsonl vs context.jsonl), Events system.
pi-mono/packages/mom/docs/events.md — detailed event JSON schema and usage.
pi-mono/packages/mom/docs/sandbox.md — Docker vs host mode security isolation details.
pi-mono/packages/mom/docs/slack-bot-minimal-guide.md — Slack app manifest and permissions.
pi-mono/packages/mom/docs/artifacts-server.md — Express+WebSocket artifacts server, Cloudflare Tunnel for public HTTPS, file watching with chokidar, live reload, path traversal protection, date-prefixed artifact organization.
pi-mono/packages/mom/docs/new.md — Multi-platform redesign: PlatformAdapter interface (Slack/Discord/CLI adapters), MomCustomTool interface with invoke_tool dispatch, bubblewrap channel isolation, unified ChannelMessage format, per-adapter config.
pi-mono/packages/mom/docs/v86.md — v86 x86 emulator sandbox evaluation: Alpine Linux in WebAssembly, 9p filesystem for host-guest exchange, state save/restore (~2s), outbound networking.

Invariants

Dual-File History: log.jsonl is the source of truth (append-only); context.jsonl is the compacted view sent to the LLM.
Workspace Isolation: Mom runs on the host by default (no isolation). Docker mode (--sandbox=docker:<name>) is recommended for security — it isolates tool execution to a container where only the data/ directory is mounted to /workspace.
Event Paths: On the host, event files live in data/events/. Inside the Docker sandbox and events.md, that same mounted directory is referred to as /workspace/events/ or workspace/events/.
Event Limits: A maximum of 5 events can be queued per channel. Events use unique filenames to avoid overwrites.
Artifacts Server: Runs Express on port 8080 with Cloudflare Tunnel for public URLs; file watching is recursive via chokidar; WebSocket live reload via ?ws=true parameter — pi-mono/packages/mom/docs/artifacts-server.md.
Multi-Platform Design: Design doc defines PlatformAdapter interface (start, stop, getChannels, sendMessage, etc.), planned adapters (Slack, Discord, CLI), MomCustomTool interface for host-side tool execution via invoke_tool, and bubblewrap per-channel isolation — pi-mono/packages/mom/docs/new.md.
Custom Tool Discovery: Custom tools are discovered from data/tools/**/index.ts (workspace-local) and ~/.pi/mom/tools/**/index.ts (global), loaded via jiti — pi-mono/packages/mom/docs/new.md.

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.
