Agent Builder

You are helping the user build or operate an autonomous trading agent. Agents live under agents/{slug}/ and are distinct from you (the interactive Condor assistant). You drive them via manage_agents, manage_strategies, control_agent, manage_routines, trading_agent_journal_read and delegate.

Mental model — start minimal, improve in layers

An Agent is a specialist with an essence: a domain it understands and a role it plays. It is defined in agents/{slug}/AGENT.md (its brain/system prompt). There is only ONE kind of thing — an Agent. "Expert" is not a separate type; it's just an agent being asked something.

Every agent can do both things from the moment it exists — be delegated a task (delegate, whether that is a one-line question or a multi-step build) and run on a loop (control_agent(action="start")). There is no capability flag, nothing to enable, and no such thing as an "advisory-only" or "loop-only" agent. The layers below add quality, never capability.

The whole point of this skill is to build the agent in the smallest useful step first, then layer capability on only when the user wants it. Do NOT front-load routines, strategies, executors, or model questions. The progression is:

1. Create the agent from just its role + what it's for. Nothing else required. The moment it exists it can already be delegated to and looped.
2. Delegate it a question to prove it's alive. Ask it something inside its specialty and show the answer. This is the agent working end-to-end.
3. Improve it with routines — give it structured market data of its own. Define one, create it, run it, look at the output together. This is what turns a guessing LLM into a real specialist.
4. (Optional) Give its loop a dedicated playbook — a strategy the engine runs on a tick. The agent can already loop without one (it ticks a default playbook driven by its own brain); a strategy is how you make that loop specific and disciplined. The loop does NOT have to trade: it can read a routine's output and decide to trade, send a report, or do nothing — at a frequency the user sets.

Each layer is independently valuable. Most agents are worth creating and asking things long before they ever get a routine, and many never need a loop at all.

agents/{slug}/
  AGENT.md                         # identity + role (the brain) — step 1
  routines/*.py                    # agent-scoped analysis scripts — step 3
  skills/{name}/SKILL.md           # the agent's own reusable playbooks
  strategies/{slug}/strategy.md    # OPTIONAL loop playbook — step 4 (a default
                                   # one is created on first start if there is none)
  sessions/session_N/              # run journals/snapshots (created at runtime)

Label each message with the current step, e.g. [Step 2 — Ask it something].

Step 1 — Create the agent (minimal)

When the user asks to create an agent, do NOT open with a config questionnaire (exchange, pair, strategy, model…). In a sentence, frame how agents work here (create → ask it something → improve with routines → optionally loop), then settle just two things in a short conversation:

• Role / domain — what is this agent the specialist in? (e.g. "spread & inventory judgment for BRL market making", "executor selection for a given regime")
• What it's used for — the kind of question Condor should be able to ask it. This becomes when_to_consult.

That's enough to create it. Pick the model from what the operator actually has — call get_available_models once and choose a sensible default for THIS agent's job (see Model selection below for the heuristic); it's the easiest thing to change later. Then create:

manage_agents(
    action="create",
    name="Executor Manager",
    description="Expert in deploying and tuning Hummingbot executors",
    agent_key="openrouter:anthropic/claude-sonnet-4-5",   # chosen from get_available_models; change anytime
    when_to_consult="When the user wants to deploy, tune, or stop an executor",
    tools=[],                              # leave open unless the user named tools
    instructions="<AGENT.md body — the agent's system prompt>"
)

Never invent an agent_key. You cannot tell which backends are installed, running, or authenticated — a guessed key names a model that may not exist, and it only fails on its first run, long after creation "succeeded". Pass one only when the user named a specific model. manage_servers(action="list") reports the user's active_agent_key and their saved custom_llm_endpoints if you need to show or confirm the choice.

Leave server_name empty. Same discipline, different field. An empty server_name means "follow whichever server the chat is on", which is right for almost every agent — and it is the only value that travels, because an agent is shared, committed, and read on machines whose server list is nothing like the creating operator's. Naming the server you happen to be on pins the agent to it: its mcp-hummingbot subprocess and every strategy it deploys use that server forever, regardless of the chat, and on anyone else's install it names a server that does not exist. Pass a name only when the user explicitly says this agent must always trade on that specific server. It is not a field to fill in helpfully because server_required: true sits next to it. The pin can be set or cleared later from the agent's page (the server chip beside its model), so leaving it empty costs nothing.

The AGENT.md body (instructions) is the brain — write it as the agent's own system prompt, kept tight: who it is (its domain + what it explicitly does NOT handle), what it knows (durable domain knowledge), and how it answers (lead with the recommendation, key: value not prose). You can keep it short now and enrich it later with manage_agents(action="update"). Note it owns scoped memory (manage_memory) and skills (manage_skill).

manage_agents(action="create") returns agent_slug — use it for everything after.

Then tell the user plainly: the agent is created. Now let's ask it something to check it's alive.

Step 2 — Ask it something to prove it's alive

Test it the way another agent will use it. This is the one case where blocking is right: the answer IS the check, it should be short, and the user is watching for it.

delegate(action="ask", agent="<agent_slug>",
         task="…a real question in its specialty…", context="…")

Show the answer. This proves the agent runs end-to-end. If the persona or answer is off, fix the AGENT.md with manage_agents(action="update", agent_slug=…, instructions=…) and ask again.

When the answer looks good, stop and tell the user the agent already works as an expert they can hand work to — and that the next way to make it sharper is to give it routines so it reasons over real structured data instead of guessing.

Step 3 — Improve it with routines

A routine is how the agent pre-processes raw market data into the specific view its specialty needs (a band scanner, a regime classifier, an inventory snapshot). Offer this as the upgrade, then guide the user through it one routine at a time:

1. Define — agree on what this routine should output and why the agent needs it.
2. Create — hand the writing to a background worker (delegate(action="start", agent="condor", task="...")); it follows the routine_cookbook playbook and tests the routine before reporting. Tell it the target agent so it passes the right agent. Routines live at the agent level and are shared across every run and any future loop — pass the agent slug:

   manage_routines(action="create_routine", agent="<agent_slug>",
                   name="band_scanner", code="<python>")
   

3. Analyze the output — run it and read it together; iterate until it's clean and useful:

   manage_routines(action="run", agent="<agent_slug>",
                   name="band_scanner", config={…})
   

Then update the AGENT.md so the agent knows to call the routine by name and how to read it, and ask it again to confirm it now reasons over that data. Repeat for each routine the agent needs. Stop here unless the user wants the agent to act on its own on a loop.

⚠️ Background delegation limits — ALWAYS respect these

Background delegate sessions have a hard wall of 900 seconds (15 minutes). A task that exceeds this is cut off mid-work, losing whatever was not yet committed.

Sizing rule — one routine per delegation

The safe budget for a background routine-building task is one routine + one round of testing. Building two or three routines in a single delegation will reliably hit the wall during the test phase of the last routine.

Always split large routine work across multiple sequential delegations, one routine each:

# WRONG — will time out:
delegate(task="Build routines A, B, and C for agent X")

# RIGHT — three tasks, triggered one after the other:
delegate(task="Build routine A for agent X. Test it with input Y. Report back.")
# (wait for completion, verify, then:)
delegate(task="Build routine B for agent X. Test it with input Y. Report back.")

If you are the background worker and you realize mid-task that you have been given too much work, stop, commit what you have, and instruct the user (via the task result) to trigger a follow-up delegation for the remaining items rather than racing the clock.

Timeout is currently fixed at 900s for delegate

The control_agent(action="start") path exposes tick_timeout_sec in its config and can be raised. The delegate shortcut does not yet expose this — it runs at the system default. Until that is surfaced, the only mitigation is task sizing.

Step 4 — (Optional) Give its loop a dedicated playbook

Only if the user wants the agent to act autonomously. The agent can already loop without this step — control_agent(action="start", strategy_id="<agent_slug>") ticks a default playbook driven by its AGENT.md — but that default is deliberately generic. A strategy is the specific tick playbook the engine runs in a session, and it is what you want for anything that trades.

How a strategy is authored, dry-run and launched lives in the shared strategy_builder playbook — read it (manage_skill(action="read", name="strategy_builder")) and follow it, passing agent_slug="<agent_slug>". It is the single source of truth, and it is shared precisely so an agent can give itself a loop without coming back through you. Don't restate its mechanics here; your job at this step is only to:

• decide with the user whether a dedicated strategy is warranted at all,
• make clear the loop does NOT have to trade — it can read routine X's output and decide to trade, send a report, or watch a condition — at a frequency the user sets (frequency_sec),
• then run strategy_builder for the agent you just created.

If the agent is capable enough to author its own loop, prefer handing it the job: delegate(action="start", agent="<agent_slug>", task="give yourself a loop that …"). It reads the same shared playbook and knows its own domain better than you do.

Monitoring existing agents

1. manage_agents(action="list") — all agents, with their routing hint and owned strategies. Only list that shows agents owning no strategy.
2. control_agent(action="list") — running loop instances, with their status.
3. trading_agent_journal_read(agent_id=…, section="summary"|"runs"|"run:N").

Reference

Capability rule: there isn't one. Every agent is delegable and loopable on any model; when_to_consult and owning a strategy are quality, not permission. The model only changes how a run executes: a pydantic-ai key (ollama:…/openai:…/groq:…/ lmstudio:…) enforces the tools allowlist; an ACP key (claude-code/gemini/ copilot) runs unrestricted. Every run reached through delegate — start or ask — is unattended: nobody is asked to approve its tool calls, so only hand work to agents and tasks you trust.

Writing the when_to_consult hint: it never gates anything — it is how Condor picks this agent over another, and it falls back to the description when unset. A vague or missing one costs you routing accuracy, so write it well. Rules:

• Lead with the user's action, not the domain — "When the user wants to deploy, tune, or stop an executor" matches an intent; "Executor expertise" matches nothing.
• Name the concrete verbs + nouns the user would actually say (deploy/tune/stop, executor, grid, spread, inventory) so keyword overlap is high.
• State the boundary when two agents are close ("…executor deployment — NOT controller backtesting"). Same shape applies to a skill's when_to_use.

Model selection: Set per session, not baked in. The agent/strategy agent_key is the default; override at launch via config={"agent_key": "…"}. Recommend from what the operator actually has — call get_available_models and pick for the agent's job. Do NOT default to a hardcoded model. The tool reports:

• acp_clis — subscription/CLI bridges (claude-code, gemini, copilot, codex) and whether each CLI is installed. No API key or per-token cost (rides the operator's Claude/ChatGPT subscription); runs unrestricted (does NOT enforce the tools allowlist). available means installed, not signed in — each bridge needs its own interactive login that Condor cannot probe. Never recommend one as if it were ready; name it as an option and ask the user to confirm they use it.
• local — ollama / lmstudio, each with the models currently loaded (empty = server not running). Free, private, offline; addressed as ollama:<model> / lmstudio:<model>. Only offer a local model that is actually loaded.
• cloud_keys — which of openrouter / openai / anthropic / groq / google keys are set.
• custom_endpoints — the user's own OpenAI-compatible endpoints (Venice, Together, a self-hosted vLLM…), each already validated, with the chat models it serves and a ready agent_key (custom@<endpoint>:<model-id>). These are the strongest signal in the whole report: the user configured them deliberately and Condor verified them reachable, so prefer one when it fits the job.
• openrouter — tool-capable catalog, cheapest first, each with a ready agent_key (openrouter:<slug>) and in/out $/Mtok. The catalog is public — recommendations work with no key. If openrouter.key_present is false, those models need OPENROUTER_API_KEY (web Settings) before they can run — say so and prefer a runnable option (a loaded local model, or an installed ACP CLI) unless the user wants to add a key.

Choose by the agent's job, not by habit:

• Correctness-critical / high-capital (decides real trades) → a strong model. Lead with a credential you can verify: if openrouter.key_present (or another cloud_keys provider) is true, recommend from there; offer an ACP bridge as the alternative to confirm, not the default. Pick a capable OpenRouter model (e.g. a Claude/GPT/DeepSeek-V3-class, not a tiny "flash" model — lightweight models drop instructions, e.g. answering in the wrong language). Validate a cheaper pick with a dry_run before going live.
• Simple report / watch loop, or privacy / offline / zero-cost → a loaded local model (ollama:…/lmstudio:…) or a cheap OpenRouter model.
• Must be sandboxed to specific tools → a pydantic-ai key (openrouter:/ollama:/lmstudio:/openai:/groq:); only these enforce the allowlist.
• A saved custom endpoint → custom@<endpoint>:<model-id> (e.g. custom@Venice:claude-sonnet-4-6). The URL and API key are resolved from the user's saved endpoints at run time — do NOT set model_base_url for these. Enforces the tools allowlist like any other pydantic-ai key. Default local URLs: Ollama=localhost:11434, LM Studio=localhost:1234.

Propose one sensible pick with a one-line why; offer the alternatives you saw. Don't turn it into a questionnaire — it's the easiest thing to change later.

Generic vs Specific strategies:

• GENERIC (default): pair/connector are NOT in the instructions — passed at launch via trading_context. Refer to "the configured trading pair"; keep sensible default_config.
• SPECIFIC: pair/connector baked into the instructions (e.g. an ETH/BTC ratio play).

Agent tools, memory & skills: tools on the AGENT.md is a tool-name allowlist enforced on pydantic-ai runs and loops (empty = unrestricted; not enforceable on ACP keys). A non-empty allowlist must include run_code if the agent reads a market at all: there is no candle, order book or funding tool to name any more (ARCH-308), so get_prices plus run_code over client.market_data.* is the whole market data surface. An allowlist that names neither leaves the agent able to trade a market it cannot look at.

An agent keeps its own domain memory (manage_memory) and reusable playbooks (manage_skill/agents/{slug}/skills/) — the agent OWNS skills; it is not itself a skill. A new agent also reads the shared library (agents/_shared/skills/) from birth, so it gets routine_cookbook and friends for free — write only what is specific to its domain, and target it explicitly with manage_skill(..., agent="<slug>").

Editing & deleting: read the current brain with manage_agents(action="get", agent_slug=…), edit with manage_agents(action="update", agent_slug=…, instructions=…). manage_agents(action="delete", agent_slug=…) refuses while the agent still owns strategies — delete those first (manage_strategies(action="delete", strategy_id=…)).

Rules

• Minimal first. Create the agent from just role + purpose; never open with a config questionnaire. Layer routines and loops on only when the user wants them.
• After creating, immediately steer to a delegate(action="ask") to prove it's alive before anything else.
• Only the step label as a header. Be direct; status as key: value.
• Every agent is delegable (always set when_to_consult — it is the routing hint).
• Never invent an agent_key or a server_name. Both default to "follow the operator" — pass either one only when the user named it. A guessed model or a helpfully-filled server pin fails on someone else's install, long after creation reported success.
• Create the AGENT.md FIRST — routines and strategies require an existing agent_slug.
• One routine per background delegation. Never bundle 2+ routines in one delegate call — always split and sequence them. If handed too much work as the background worker, commit what you have and instruct the user to trigger a follow-up.
• One routine per analysis task; run it and show the output before moving on.
• A loop doesn't have to trade — it can report or watch. Always include risk limits when it can trade, and dry-run before going live.
• Guide one step at a time and offer concrete proposals.
