From 521c644487045e158e9e795e05f24e70e5ea9523 Mon Sep 17 00:00:00 2001 From: Kowser Date: Thu, 9 Jul 2026 19:07:42 -0700 Subject: [PATCH 1/3] merge Agentspan Java SDK: conductor-ai modules, sources verbatim Four new Gradle modules carrying the agent SDK from agentspan-ai/agentspan sdk/java @ f8704fa3: - conductor-ai core SDK (107 main + 29 test files) - conductor-ai-spring Boot 3 auto-configuration (3 main + 2 test) - conductor-ai-e2e 26 e2e suites, all tasks gated behind -Pe2e - conductor-ai-examples 158 runnable examples (-PmainClass runner) Sources are copied verbatim; the only churn is a mechanical spotlessApply conforming them to the repo conventions (Apache header, Conductor import order). Build files clone the shapes of conductor-client-metrics, conductor-client-spring, tests, and harness respectively; conductor-ai[-spring] publish via publish-config as org.conductoross:conductor-ai[-spring]. Upstream docs land under docs/agents/ (content pass to follow).

The LLM then hallucinates +a "I can't access external sources" answer. The example workflow +shows `COMPLETED` with 12 `COMPLETED_WITH_ERRORS` HTTP sub-tasks. + +**Fix vector:** server-side. Either route to Gemini's native grounding +when the LLM provider is Gemini, ship a real Google Search adapter +with API-key configuration, or reject `GoogleSearchTool` when no +backend is configured. Tracked separately. + +### 2. ADK callbacks compile to a no-op for the simple-LLM agent shape + +`adk.Example23Callbacks` registers `beforeModelCallback` and +`afterModelCallback`. The SDK forwards `_worker_ref` placeholders in +the wire payload (verifiable in the workflow metadata's `agentDef` +field), and `GoogleADKNormalizer` builds `CallbackConfig` objects from +them. **The downstream workflow compiler does not yet emit Conductor +hook tasks** for these on the simple-LLM path, so the registered +worker is never polled (workflow has 1 task: just the LLM call). + +Python ADK has the same gap — see +`sdk/python/examples/adk/14_callbacks.py` comment.

The PAE planner's static {@code instructions} string is fine for + * how to emit a plan, but it's a poor fit for the domain-specific + * rules a real plan depends on — tier thresholds, KYC step ordering, + * region exceptions, escalation rules. Those live in docs that change + * weekly, not in code. + * + *

{@code plannerContext} solves this: a list of text snippets and/or + * URLs appended to the planner's user prompt as a {@code ## Reference + * Context} block on every planner invocation. URLs are fetched + * dynamically — no compile-time fetch, no cache — so a Confluence edit + * lands on the next plan run with zero redeploy. + * + *

This example runs WITHOUT a real Confluence backend — the + * {@code plannerContext} is text-only by default so you can run it + * against a stock server without setting up credentials. The + * {@code Context.builder().url(...).header(...)} example below is + * commented as a reference for how real installations wire credentialed + * docs. + * + *

ADK itself doesn't ship a guardrail abstraction — its safety story is + * {@code beforeModelCallback} returning a short-circuit response, which the + * server doesn't yet compile into hook tasks (see Example23). Agentspan + * provides a separate, server-compiled guardrail mechanism that runs as a + * Conductor task inside the agent's loop. This example shows how to attach + * Agentspan guardrails to a pure ADK agent without giving up the drop-in + * pattern. + * + *

Pattern: + *

    + *
  1. Build the native ADK {@link LlmAgent} exactly as you would for ADK.
    2. + *
  2. Hand it to {@link AdkBridge#agentBuilder} (NOT {@code toAgentspan} — + * the builder variant lets you decorate before building).
    3. + *
  3. Attach a {@link GuardrailDef} with a validation function that + * returns {@link GuardrailResult#pass()}, {@link GuardrailResult#fail + * fail(message)}, or {@link GuardrailResult#fix fix(rewrittenOutput)}.
    4. + *
  4. {@link Agentspan#run} executes the agent with the guardrail running + * server-side after each LLM turn; failures retry (up to + * {@code maxRetries}) or fix-substitute depending on {@link OnFail}.
    5. + *
+ * + *

LangChain4j has no built-in guardrail abstraction. Agentspan provides a + * server-compiled guardrail mechanism that runs as a Conductor task inside the + * agent's loop. This example attaches a PII-redaction guardrail to a pure + * LangChain4j agent built from a native {@code ChatModel}. + * + *

Pattern (same as + * {@code adk.Example38AgentspanGuardrails}): + *

    + *
  1. Build native LangChain4j {@code ChatModel}.
    2. + *
  2. Hand it to {@link LangChainBridge#agentBuilder} (the builder variant + * lets you decorate before building).
    3. + *
  3. Attach a {@link GuardrailDef} with {@link OnFail#FIX} so the + * guardrail rewrites the output in place.

Demonstrates mixing: + *

    + *
  • Native LangChain4j {@code @Tool} methods that perform pure computation (no secrets)
    • + *
  • An Agentspan {@link Tool}-annotated method that reads a credential injected + * as an environment variable by the server (via the {@code credentials} field)
    • + *
+ * + *

Credential injection pattern: + *

    + *
  1. Declare credential names in {@code @Tool(credentials = {"MY_API_KEY"})}
    2. + *
  2. Store the secret once via the CLI: {@code agentspan credentials set --name MY_API_KEY}
    3. + *
  3. At runtime, the server resolves the credential and injects it as + * an environment variable before invoking the worker. Read it with + * {@code System.getenv("MY_API_KEY")}.

This pattern keeps secrets out of source code and out of agent configs. + * + *

The Java counterpart of the Python SDK's {@code @agent} decorator. Annotate a + * method to define an agent declaratively; resolve it into an + * {@link org.conductoross.conductor.ai.Agent} with + * {@link org.conductoross.conductor.ai.Agent#fromInstance(Object)} or + * {@link org.conductoross.conductor.ai.Agent#fromInstance(Object, String)}. + * + *

The method's return type declares what it provides: + *

    + *
  • {@code void} — nothing; the annotation attributes alone define the agent.
    • + *
  • {@code String} — dynamic instructions. A no-arg method is lazy: it is + * re-invoked every time the agent config is serialized (each run submission), + * so the prompt can reflect current state — matching the Python SDK, where + * callable instructions resolve at serialization time. A non-empty result wins + * over the {@link #instructions()} attribute.
    • + *
  • {@code PromptTemplate} — a server-side instructions template + * (sets {@code instructionsTemplate}); invoked once.
    • + *
  • {@code Agent.Builder} — the definition itself; the returned builder is built.
    • + *
  • {@code Agent} — the definition itself, returned as-is (CrewAI-style full + * factory). For no-arg factory forms, annotation attributes other than + * {@link #name()} are rejected — they would be silently ignored.
    • + *
+ * + *

The method may take no parameters, or a single + * {@link org.conductoross.conductor.ai.Agent.Builder Agent.Builder} parameter as an + * escape hatch: the builder arrives pre-populated from the annotation (and the + * discovered tools/guardrails/sub-agents), and the method body can apply anything + * the builder supports — termination conditions, handoffs, memory, sub-agents from + * other classes, etc. Builder-param methods are invoked exactly once (re-running a + * customizer per serialization would replay its side effects). + * + *

{@link Tool} and {@link GuardrailDef} methods declared on the same object are + * attached to the agent automatically (all of them by default — see {@link #tools()} + * and {@link #guardrails()}). Sub-agents are referenced by name via {@link #agents()}. + * + *

Example: + * 

{@code
+ * public class Weather {
+ *     @Tool(description = "Get weather for a city")
+ *     public String getWeather(String city) { return "Sunny, 72F in " + city; }

+ *     @AgentDef(model = "openai/gpt-4o")
+ *     public String weatherbot() {
+ *         return "You are a weather assistant. Today is " + LocalDate.now() + ".";
+ *     }
+ *
+ *     // builder customizer: full builder API available
+ *     @AgentDef(model = "openai/gpt-4o", instructions = "You are a researcher.")
+ *     public void researcher(Agent.Builder builder) {
+ *         builder.termination(new MaxMessageTermination(10))
+ *                .agents(Agent.fromInstance(new Editing(), "editor"));

Discovery walks the full type hierarchy — superclasses and interfaces (including `default` methods) — and the nearest annotated declaration wins.

Downloads the pinned agentspan-server-0.4.0.jar release asset (cached), boots it on :8080 with the LLM repo secrets in the server env only, starts mcp-testkit, then runs ./gradlew :conductor-ai-e2e:test -Pe2e. A guard parses the JUnit XML and fails on zero executed tests, because BaseTest assumeTrue-skips every suite when the server is unreachable — without it a boot failure would green-wash the job. Fork PRs (no secrets) fail at the guard by design. Needs OPENAI_API_KEY and ANTHROPIC_API_KEY repo secrets before it can go green.
