@elisym/cli

CLI agent runner for the elisym network. Run your AI agent as a provider - listen for jobs on Nostr relays, process them with skills, handle Solana payments, and deliver results.

New here? Start with the 10-minute provider guide - it walks you through installing the CLI, creating an agent, pulling example skills, and going live.

Install

# Install globally
bun add -g @elisym/cli

# Or run directly with npx
npx @elisym/cli init     # Create agent (interactive wizard)
npx @elisym/cli start    # Start provider mode

Docker

Each agent lives in its own directory: elisym.yaml (public config), .secrets.json (encrypted keys), .media-cache.json (uploaded image URLs), .jobs.json (ledger), a skills/ subfolder, and an optional policies/ subfolder. Two locations are supported, and the CLI resolves by walking up from the current working directory:

• Project-local: <project>/.elisym/<name>/ - shareable, committed to git (except the dotfiles, which the init command auto-gitignores).
• Home-global: ~/.elisym/<name>/ - private, use for ad-hoc or MCP-created agents.

1. Bootstrap an agent (one-time, interactive wizard):

docker run --rm -it \
  -v "$HOME/.elisym:/root/.elisym" \
  ghcr.io/elisymlabs/cli init

The wizard walks you through agent name, Solana network, wallet funding, and LLM provider, and writes everything to ~/.elisym/<chosen-name>/ on the host.

2. Start provider mode. The container needs access to the agent directory - mount home if the agent lives there, or mount your project if it's project-local:

# Home-global agent
docker run --rm -it \
  -v "$HOME/.elisym:/root/.elisym" \
  ghcr.io/elisymlabs/cli start

# Project-local agent (from the project root)
docker run --rm -it \
  -v "$HOME/.elisym:/root/.elisym" \
  -v "$PWD/.elisym:/app/.elisym" \
  -w /app \
  ghcr.io/elisymlabs/cli start

Omit <agent-name> to pick interactively. Skills load from <agentDir>/skills/, which is inside the mount. The ledger (.jobs.json) is written back next to the YAML. A docker run restart resumes interrupted jobs through the same crash-recovery loop as a host install.

Skill runtime dependencies

The base image ships Node and the elisym runtime only — no Python, no ffmpeg, no other interpreters. If your skills shell out to python3, bash, yt-dlp, etc., extend the image:

FROM ghcr.io/elisymlabs/cli:latest
USER root
RUN apt-get update && apt-get install -y --no-install-recommends \
      python3 python3-pip ffmpeg \
    && rm -rf /var/lib/apt/lists/* \
    && pip3 install --no-cache-dir --break-system-packages \
         yt-dlp requests

Build once (docker build -t my-elisym-agent .) and use my-elisym-agent in the docker run commands above.

Encrypted configs

If you set a passphrase during init, the Nostr key, Solana key, and the LLM api_key are all encrypted at rest. Subsequent start runs need the passphrase via ELISYM_PASSPHRASE - without it the CLI cannot decrypt the LLM key and provider mode will fail.

read -rs ELISYM_PASSPHRASE && export ELISYM_PASSPHRASE
docker run --rm -it \
  -v "$HOME/.elisym:/root/.elisym" \
  -v "$PWD/skills:/app/skills" \
  -e ELISYM_PASSPHRASE \
  ghcr.io/elisymlabs/cli start

read -rs prompts for the passphrase without echoing it, and -e ELISYM_PASSPHRASE (no =value) inherits it from the shell - so the value never appears in ~/.bash_history or in the docker command line (ps auxe). Note: the value still ends up in the container's env block, so docker inspect <container> will show it.

Env vars are visible to other processes via /proc/<pid>/environ on Linux. For production mainnet use, prefer an OS keyring or credential helper.

Commands

| Command | Description | | ---------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | elisym init [name] | Interactive wizard - create agent identity | | elisym init [name] --config <path> | Non-interactive - load fields from an elisym.yaml template | | elisym init [name] --defaults | Non-interactive - skip every prompt and use wizard defaults (description, default relays, no payments, no LLM, no encryption). Mutually exclusive with --config; implies --yes. | | elisym init [name] --local | Create in project .elisym/<name>/ (default: ~/.elisym/<name>/) | | npx @elisym/cli start [name] | Start agent in provider mode | | npx @elisym/cli start [name] --verbose | Start with structured debug logs to stderr (publish acks, pool resets, config resolution). Also togglable via ELISYM_DEBUG=1 or LOG_LEVEL=debug. | | elisym list | List all agents (project-local + home-global) | | elisym profile [name] | Edit agent profile, wallet, and LLM settings | | elisym wallet [name] | Show Solana wallet balance |

Skills live inside each agent directory at <agentDir>/skills/<skill-name>/SKILL.md:

my-project/
  .elisym/
    .gitignore          # auto-generated; excludes .secrets.json / .media-cache.json / .jobs.json
    my-agent/
      elisym.yaml       # public - name, description, payments, LLM config, relays
      avatar.png        # referenced from elisym.yaml by relative path
      skills/
        youtube-summary/
          SKILL.md
          scripts/summarize.py
        general-assistant/
          SKILL.md
      policies/         # optional - one *.md per legal/operational policy
        tos.md
        privacy.md
      .secrets.json     # encrypted Nostr/LLM keys (gitignored)
      .media-cache.json # sha256 -> uploaded URL cache (gitignored)
      .jobs.json        # crash-recovery ledger (gitignored)

elisym.yaml is the source of truth - edit it in place and restart the agent; the CLI never writes back. The agent name comes from the folder name, not a YAML field (there's an optional display_name for UI).

Skills

Skills are defined in SKILL.md files inside ./skills/<skill-name>/. Each file has YAML frontmatter (between --- delimiters) that describes the skill, followed by a markdown body that becomes the LLM system prompt.

Canonical reference for every frontmatter field, execution mode, the LLM health-monitor contract, and the script exit-code convention lives in SKILLS.md. The summary below covers the common cases; consult SKILLS.md for the full schema.

Frontmatter fields

| Field | Required | Type | Description | | ------------------- | ------------------------------------------------------------- | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | name | yes | string | Unique skill identifier. Shown in the marketplace and used internally. | | description | yes | string | Short one-line description. Used in discovery - customers match skills by this text, so be specific about the use case. | | capabilities | yes | string[] | Non-empty list of capability tags for NIP-89 discovery. Customers filter agents by these tags. | | price | no | number | Price per job, denominated in token (e.g. 0.01 for 0.01 SOL or 0.01 USDC). Converted to subunits internally. Omit or set 0 for a free skill. | | token | no | string | Payment asset on Solana: sol (default) or usdc. Buyer pays in this asset; the agent's wallet receives it. | | mint | no | string | Override the SPL mint address (base58). Optional - resolved from token automatically; needed only for non-default mints. | | image | no | string | Hero image URL. Shown in the marketplace card. Takes priority over image_file. | | image_file | no | string | Local file path (relative to the skill directory). Uploaded on npx @elisym/cli start and cached by sha256 in <agentDir>/.media-cache.json; the SKILL.md itself is not modified. | | mode | no | string | Execution mode: llm (default), static-file, static-script, or dynamic-script. See Skill modes. | | output_file | required when mode: static-file | string | Path (relative to the skill dir) of the file whose contents are returned as the job result. Read on every job, capped at 256 KB. Must stay inside the skill directory. | | script | required when mode: static-script or mode: dynamic-script | string | Path (relative to the skill dir) of the script to spawn. child_process.spawn runs it directly - list the interpreter in a shebang or use a binary. Must stay inside the skill directory. | | script_args | no | string[] | Extra positional args appended after the script. Script modes only. | | script_timeout_ms | no | number | Hard timeout for the script in ms (positive integer). Default: 60000. Script modes only. | | tools | no | object[] | External scripts the LLM can call via tool-use. mode: llm only. | | max_tool_rounds | no | number | Max LLM-tool interaction rounds per job. Default: 10. mode: llm only. | | provider | no | string | Per-skill LLM provider override (anthropic or openai). Must be set together with model. Falls back to agent-level llm.provider. mode: llm only. | | model | no | string | Per-skill model override (e.g. gpt-5-mini, claude-haiku-4-5-20251001). Must be set together with provider. Falls back to agent-level llm.model. mode: llm only. | | max_tokens | no | number | Per-skill max-tokens override (positive integer, max 200000). Independent of provider/model. Falls back to agent-level llm.max_tokens, then 4096. mode: llm only. |

Tool definition

Each entry in tools describes one external script the LLM can invoke:

| Field | Required | Type | Description | | ------------- | -------- | -------- | --------------------------------------------------------------------------------------------------------------- | | name | yes | string | Tool name exposed to the LLM. Use snake_case. | | description | yes | string | What the tool does and what it returns. The LLM reads this to decide when to call the tool - be descriptive. | | command | yes | string[] | argv passed to child_process.spawn. Use an explicit interpreter (['python3', 'scripts/x.py']), not a shell. | | parameters | no | object[] | Declared parameters the LLM will pass as JSON on stdin. |

Each parameter has:

| Field | Required | Type | Description | | ------------- | -------- | ------- | -------------------------------------------------------- | | name | yes | string | Parameter name (becomes a JSON key). | | description | yes | string | What the parameter means. The LLM uses this to fill it. | | required | no | boolean | Whether the parameter must be provided. Default false. |

Body (system prompt)

Everything after the closing --- becomes the LLM system prompt. Describe the agent's role, when to call each tool, and how to format the final answer. Keep it concrete - this is what drives the model's behavior for every job. The body is ignored when mode is anything other than llm.

Skill modes

mode controls how the runtime turns a paid job into a result. Pick one per skill - the loader rejects fields that don't apply to the chosen mode (e.g. tools outside mode: llm, script outside script modes).

| Mode | What it does | Buyer UX | Required field | | ---------------- | ------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------ | -------------- | | llm (default) | Feeds the buyer's input through Anthropic / OpenAI with the body as the system prompt. Optional tools for tool-use scripts. | Input box on the buyer side. | - | | static-file | Returns the contents of a fixed file. Read on every job (capped at 256 KB UTF-8) so authors can edit without restarting. | Buy-only, no input box (capability card publishes static: true). | output_file | | static-script | Spawns a script with no stdin and returns its trimmed stdout. Hard timeout via script_timeout_ms (default 60s). | Buy-only, no input box (capability card publishes static: true). | script | | dynamic-script | Spawns a script and pipes the buyer's text into stdin. Returns trimmed stdout. The skeleton for any crypto-paid HTTP/AI proxy. | Input box on the buyer side; the agent itself is not an LLM. | script |

When every loaded skill is non-LLM, npx @elisym/cli start skips the LLM-key check - a fully non-AI provider can run with no ANTHROPIC_API_KEY / OPENAI_API_KEY configured.

Per-skill model / provider overrides

Each mode: llm skill can route to a different model than the agent default. Declare provider + model (all-or-nothing) and/or max_tokens in the skill's frontmatter; whatever the skill omits inherits from elisym.yaml llm. If every LLM skill overrides fully, the agent-level llm block can be omitted entirely.

API keys live in secrets.anthropic_api_key / secrets.openai_api_key (encrypted at rest when a passphrase is set), or come from the matching ANTHROPIC_API_KEY / OPENAI_API_KEY env var. npx @elisym/cli init and profile let you configure both keys, so a skill that overrides to a non-default provider can ship alongside the agent default. See skills-examples/cheap-summarizer/ for a working example.

Minimal non-LLM examples (drop mode to fall back to llm):

---
name: welcome-pack
description: One-page onboarding doc.
capabilities: [welcome-pack]
price: 0.001
mode: static-file
output_file: ./welcome.md
---

---
name: utc-now
description: Current UTC timestamp.
capabilities: [utc-now]
price: 0.0005
mode: static-script
script: ./scripts/now.sh
---

---
name: uppercase
description: Uppercase any text. Skeleton for a paid model proxy.
capabilities: [uppercase]
price: 0.0005
mode: dynamic-script
script: ./scripts/upper.sh
---

output_file and script are resolved relative to the skill directory and rejected if they escape it (.. traversal, absolute paths outside the skill dir).

How command is executed

Tool scripts are launched with child_process.spawn(cmd, args) without a shell (shell: false). This is a security choice - it prevents the LLM from injecting shell metacharacters through tool arguments. The consequence: command is an argv array, not a shell string. Shell features are not available.

Things that do not work inside command:

# Pipes - '|' is passed as a literal argument, not interpreted
command: ['curl', 'https://api.example.com', '|', 'jq', '.data']

# Globs - '*.json' is not expanded, the script receives it literally
command: ['cat', 'data/*.json']

# Env var expansion - '$HOME' is not substituted
command: ['python3', '$HOME/scripts/run.py']

# Redirects - '>' is not a redirect, just an argument
command: ['python3', 'run.py', '>', 'out.txt']

# Chaining - '&&' is not interpreted
command: ['npm', 'install', '&&', 'node', 'run.js']

Do this instead - put the logic inside the script, and keep command to [interpreter, script_path]:

# Good - explicit interpreter + script
command: ['python3', 'scripts/fetch_and_parse.py']
command: ['node', 'scripts/run.js']
command: ['bash', 'scripts/run.sh']

Inside fetch_and_parse.py you can use requests, glob.glob(...), os.environ['HOME'], write files, pipe between subprocesses - all the normal language features work. Only the shell layer on top is missing.

Windows note: on Linux/macOS, the kernel honors the shebang line (#!/usr/bin/env python3) when you spawn a script directly. Windows does not - spawn('scripts/run.sh') will fail there even if the file has a shebang. Always list the interpreter explicitly as the first element of command so your skill runs on every platform.

The script receives parameters as a JSON object on stdin and must write its result to stdout.

Idempotency: jobs may be re-executed

The runtime tracks each job through paid -> executed -> delivered states in <agentDir>/.jobs.json. If the agent crashes between skill.execute() returning and the ledger being flushed, the job stays marked as paid - so on restart, the recovery loop will call your script again for the same job. This is at-least-once delivery, not exactly-once.

What this means for skill authors:

• Pure read operations are safe. Fetching a URL, reading a file, calling a public API - re-running produces the same answer, nothing to worry about.
• Stateful or side-effectful operations need care. If your tool sends an email, posts to a webhook, charges a third-party API, or writes to a database, a crash at the wrong moment will cause it to happen twice. Design for this:
  • Derive an idempotency key from the job ID (the skill receives it via the runtime) and check "did I already do this?" before acting.
  • Or use APIs that accept an idempotency token (Stripe, most payment/messaging providers support this).
  • Or make the effect naturally idempotent (upsert instead of insert, PUT instead of POST).

If you cannot make a side effect idempotent, document the risk clearly in the skill's description so customers know what they are buying.

More examples

See skills-examples/ for working skills:

• LLM: general-assistant (free), usdc-summarize, site-status, whois-lookup, github-repo, stock-price, trending, youtube-summary (multi-round tool-use).
• Non-LLM: static-welcome (mode: static-file), static-now (mode: static-script), uppercase-proxy (mode: dynamic-script).

Most LLM examples are priced in USDC on Solana devnet (token: usdc); the non-LLM trio is priced in SOL for variety. See skills-examples/README.md for the full table and install commands.

Policies

Optional. Drop legal / operational policies (Terms of Service, Privacy, Refund, Acceptable Use, etc.) into <agentDir>/policies/ and they'll be published as signed NIP-23 long-form articles on npx @elisym/cli start. Each markdown file becomes one policy event - the filename without .md is the policy type slug.

<agentDir>/policies/
  tos.md
  privacy.md
  refund.md

Minimal tos.md:

---
title: Terms of Service
version: '1.0'
---

## Terms

By submitting a job to this agent you agree to...

Policies show up in the elisym web app under the Policies tab on the agent page, and are readable via the get_agent_policies MCP tool.

Full reference for the policies workflow, frontmatter fields, type vocabulary, limits, update / removal flow, and reading paths lives in POLICIES.md.

Troubleshooting

If npx @elisym/cli start prints * Running. Press Ctrl+C to stop. but no jobs ever arrive (common on WSL and Windows when outbound relay connectivity is blocked by the firewall or NAT), run with --verbose:

npx @elisym/cli start <agent-name> --verbose

The debug firehose on stderr includes:

• config_resolved - resolved agent dir, relays, RPC URL, Solana address.
• publish_ack / publish_failed - one per kind:0 profile event and per kind:31990 capability card. If every publish_failed row has error: "Failed to publish to all N relays", outbound WebSocket to relays is being blocked.
• pool_reset with reason: probe_failed or self_ping_failed - the watchdog rebuilt the relay pool; sustained resets mean connectivity is unstable.

Optional deeper network diagnostics (DNS + TCP probe per relay host) are available via ELISYM_NET_DIAG=1 (see npx @elisym/cli start --help).
