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.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00118 | $0.02737 |
| Opus 5.5 | $0.00047 | $0.01095 |
| Sonnet 5.5 | $0.00024 | $0.00547 |
| Haiku 4.5 | $0.00012 | $0.00274 |
Grade A, and why
heartbeat 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 369 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Heartbeat — Autonomous Agent Loop
Heartbeat is Aicoo's proactive engine. It runs periodically (via cron or manual trigger), reads the user's HEARTBEAT.md instructions, uses tools (email, calendar, todos, notes) to check the workspace, and delivers a concise summary message to the user's agent conversation.
Concepts
| Concept | Meaning |
|---|---|
| HEARTBEAT.md | User-editable instruction file in /Memory/Self/. Defines what the agent checks each run. |
| Tier | MESSAGES (default) = read-only checks + summary. ACTIONS = can take write actions (future). |
| Run | A single execution of the heartbeat loop. Tracked in heartbeat_runs. |
| Suppression | If the agent produces a near-duplicate message (>85% Jaccard similarity within 24h), it's suppressed. |
| Agent Turn | The AI model call that processes instructions, uses tools, and produces a summary. |

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.
- 2mo ago First seen · 369 lines · 118 tokens per session scan A 03eb5a3e7727
heartbeat is a skill published in the GitHub repository Aicoo-Team/AICOO-Skills (35 stars, last pushed 3mo ago), licensed MIT. It adds 118 tokens to every session and 2,737 once invoked, about $0.0005 per session on Opus 5.5. 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 2026-08-30.
Other skills, from other repositories
todos
Use when the user asks for a shared plan, a task needs at least three substantive execution steps, or a loose TODO is pending. Without an explicit plan request, not for one-shot answers or checks, or one- to two-step work that is not already in the list.
computer-use
Read and drive native desktop apps through the accessibility layer — list apps, snapshot a window as a numbered element tree, then click/type/scroll/drag by element index or screen coordinates. Use for a desktop app, not a web page. macOS + Windows; off unless enabled in Settings.
meetings
Context for the Meetings app's data — where a meeting's notes, diagram, transcript-derived tasks and calendar cache live, what the lifecycle states mean, how the app's agents are driven. Load when asked about a meeting's notes or action items, or when touching the meetings app data dir.
mochi-remind
Handle due reminders — notify the user with natural language and mark them done.
agent-initialization
Initialize or extend an Agent from a user requirement - write AGENTS.md, set identity metadata, and create, install or import Skills and hook packages (scripts the harness runs on every prompt, before tool calls, or after a task). For an Agent with an in-app workbench, pair with penguin-plugin; for a standalone…
computer-history
Answer questions about what the user recently did on their computer — who contacted them, what they were working on, where they left off — by reading the local Computer History summaries and raw event streams.
