elizaOS is an open-source TypeScript framework and product stack for building and running autonomous AI agents. Developers use its runtime, application, command-line tool, cloud services, native bridges, and plugins to create agent-based software. The catalogue entries provide skills, commands, instructions, and rules for working with this monorepo and its agent ecosystem.
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 | $0.00065 | $0.00593 |
| Opus 5 | $0.00032 | $0.00296 |
| Sonnet 5 | $0.00013 | $0.00119 |
| Haiku 4.5 | $0.00006 | $0.00059 |
Grade A, and why
eliza-app-development 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 11d 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 — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
eliza app development
This repository is an elizaOS application: a local-first assistant with CLI, dashboard, Electrobun desktop shell, connectors, and Eliza Cloud integration. Eliza is this app’s product and CLI name—not a separate platform from elizaOS.
Read These References First

Editing Heuristics
- Prefer
packages/app-core/for app shell behavior (API, CLI, onboarding, config). - Prefer
packages/agent/for agent providers, services, and runtime glue around elizaOS. - Prefer
packages/app/for UI work andpackages/app-core/platforms/electrobun/for the Electrobun native shell. - Treat
packages/cloud/as the Eliza Cloud product and backend surface.
Hard Constraints
- Do not remove
NODE_PATHsetup. - Do not remove the Bun exports patch.
- Do not remove Electrobun startup error guards.
- Keep Node and Bun paths working.
Repo Workflow
bun install
bun run verify
bun run test
Narrower commands when useful:
bun run start
bun run dev
bun run dev:desktop
bun run test:e2e
Where to Look First
- Product and runtime behavior:
packages/app-core/src/ - Prompt, provider, and skill plumbing:
packages/agent/src/ - Onboarding and routing:
packages/ui/src/first-run/andpackages/app-core/src/runtime/ - Shipped default skills: bundled in
@elizaos/skills, seeded into the state-dir skills folder bypackages/app-core/scripts/ensure-skills.mjs - Eliza Cloud backend or monetization:
packages/cloud/and the shippedeliza-cloudskill
Cloud Default
If the task involves building an app and Eliza Cloud is enabled, linked, or explicitly requested, treat Cloud as the default managed backend before inventing custom auth, billing, analytics, or hosting. Use the eliza-cloud skill for app, monetization, and container details.
What ships with it
3 files 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.
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.

eliza-app-development is a skill published in the GitHub repository elizaOS/eliza (19,313 stars, last pushed today), licensed MIT. It adds 65 tokens to every session and 593 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.
