continuum-agent

continuum-agent is a skill for Claude Code, Codex from shyftlabs/continuum. It costs 74 tokens per session (1,287 once invoked), scanned A, original, Apache-2.0.

Build BaseAgent instances and run them with AgentRunner — covers fields, lifecycle hooks, structured outputs, ReAct mode, instruction modifiers, and the full execution flow. Invoke when the user asks "create an agent", "configure maxturns", "add lifecycle hooks", "structured output with Pydantic", or anything around…

Token cost

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.

Security

Grade A, and why

continuum-agent 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 today.

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.

Core API

from continuum.agent import BaseAgent, AgentRunner
from continuum.agent.config import AgentConfig, AgentMemoryConfig, RunnerConfig
from continuum.agent.types import (
    Handoff, MemoryScope, RunContext, AgentResponse, EventType,
)

Minimal agent

agent = BaseAgent(
    name="my-agent",                    # required, [A-Za-z0-9_-]+
    instructions="...",                 # supports {slot} templates
    model="gpt-4o-mini",                # provider chosen by prefix
    temperature=0.7,
    max_tokens=None,
)

runner = AgentRunner()
resp = await runner.run(agent, "user input", user_id="u1", session_id="s1")
print(resp.content)
print(resp.usage.total_tokens)
print(resp.structured_output)           # populated if output_schema set

Important BaseAgent parameters

memory_config AgentMemoryConfig() search_memories=True / store_memories=True
output_schema None Pydantic model
template_vars {} static slots
examples [] few-shot
instruction_modifiers [] dynamic prompt rewriters
on_start / on_end / on_error / on_tool_call / on_handoff None sync callables
config AgentConfig() max_turns=25, react_mode, reasoning_mode, scanners, strict_security, max_consecutive_handoffs=3 (same request to the same target before HandoffLoopError; fan-out over N items is never blocked), …
gateway_mode None Smart Gateway routing: "strict" / "modest" / "quality"
policy_store None Access-control store. None = fail-open (no authorization). Use PolicyStore.default_deny([...]) to fail closed; set AgentConfig(strict_security=True) to raise when side-effectful tools have no policy

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.
