Hope Agent is a cross-device personal AI assistant that remembers context, uses tools, and continues working toward goals through dynamically organized workflows. Individuals use it from desktop, web, server, or messaging environments to manage projects, knowledge, designs, and long-running tasks. The catalogue add-ons extend its agent workflows and capabilities.
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.

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 | $0.00055 | $0.01743 |
| Opus 5 | $0.00028 | $0.00872 |
| Sonnet 5 | $0.00011 | $0.00349 |
| Haiku 4.5 | $0.00006 | $0.00174 |
Grade A, and why
mermaid-diagram 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 13d 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.
How it starts
The opening of the file, as written. The whole thing — 204 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mermaid Diagram
When to Use
Trigger phrases: "draw a diagram", "flowchart for …", "sequence diagram", "architecture diagram", "ER diagram", "state machine", "gantt chart", "画一个流程图", "画个架构图".
Mermaid is rendered natively in Hope Agent chat (via Streamdown). Just emit a fenced ```mermaid block — the user sees the rendered SVG, no setup.
For diagrams Mermaid can't express (organic shapes, custom illustrations, hand-drawn style) consider drawing-tool skills (e.g. excalidraw from Hermes Agent or drawio from Anthropic marketplace) — those need to be installed via Quick Import.
Pick the Right Diagram Type
| Intent | Mermaid type | Use when |
|---|---|---|
| Step-by-step process | flowchart |
Decisions, branching, "if X then Y" |
| Time-ordered messages between actors | sequenceDiagram |
API call traces, distributed protocols |
| State transitions of a single entity | stateDiagram-v2 |
UI state machines, workflow engines |
| Data model relationships | erDiagram |
Database schema, entity relationships |
| Project schedule / timeline | gantt |
Roadmaps, sprints |
| Pie / distribution | pie |
Quick share-of-X visualization |
| Tree hierarchy (org chart, decomposition) | flowchart TD with subgraphs |
Org / breakdown trees |
| Class hierarchy with methods | classDiagram |
OO design, type relationships |
| User journey (steps + sentiment) | journey |
UX flows |
If unsure, default to flowchart. It's the most flexible.

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.

mermaid-diagram is a skill published in the GitHub repository shiwenwen/hope-agent (1,597 stars, last pushed 3d ago), licensed MIT. It adds 55 tokens to every session and 1,743 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
skin-creator
Create and apply a two-asset LobsterAI visual skin from the user's style description. Use only when the AI Skin Designer kit supplies the structured skinpack workflow marker; do not use for ordinary theme or image requests.
canvas-design
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
genui
Render structured, glanceable, interactive UI in the chat instead of plain text — dashboards, stat cards, filterable tables, charts, mermaid diagrams, choice panels, forms, quizzes. Panels can carry an id so later turns update them in place, and most interaction resolves in the browser with no round-trip. Read this…
artifact-design
Design guidance for any HTML/Markdown file shown in octo's Artifacts panel — reports, dashboards, architecture/system diagrams, generated UIs, slide-style pages, 3D scenes. Read this BEFORE writing the file, not after — it calibrates how much design effort the request warrants and covers the panel's real constraints…
memory
Use this skill when Pioneer should proactively use durable memory or recalled context: decide whether memory can improve a turn, answer from remembered user/project facts, request memory tools, search/list/get stored memories, save durable preferences or project decisions, forget memories, audit or clean up memory, or…
subagents
Use this skill when Pioneer should delegate current-turn work to attached task-backed subagents, coordinate parallel child agents, wait for child results, review/revise/accept/cancel/detach attached work, or synthesize accepted child results into the parent answer.
