Previously live events were appended to the session but never passed through any plugin hook, so token usage emitted by Gemini Live (including audio modality breakdowns) could not be captured by plugins. Add LiveTokenTrackingPlugin which observes usageMetadata on each event and logs per-invocation totals on run completion. Live reports cumulative counts, so the plugin keeps the latest value per field rather than summing.

It uses Gemini to analyze each issue, +recommend labels that actually exist in `adk-java`, and assign an owner based on +a configurable round-robin rotation. + +This sample is the Java port of +[`adk-python/contributing/samples/adk_team/adk_triaging_agent`](https://github.com/google/adk-python/tree/main/contributing/samples/adk_team/adk_triaging_agent), +adapted to the **real label taxonomy of `adk-java`**.

All GitHub access goes through the shared `GitHubTools` (backed by the +[`org.kohsuke:github-api`](https://github-api.kohsuke.org/) client) that this +sample reuses with the ADK Docs Release Analyzer. + +-------------------------------------------------------------------------------- + +## Triaging Workflow + +The agent performs different actions based on the issue state: + +| Condition | Actions | +| ---------------------------------- | -------------------------------------- | +| Issue without a recognized label | Add a kind label | +: : (`bug`/`enhancement`) + optional topic : +: : label : +| Issue without an assignee | Round-robin assign an owner | +| Issue with no recognized label AND | Add label(s) + Assign owner | +: no assignee : : + +### Labels + +The agent may only apply labels that exist in `google/adk-java`, listed in +`AdkTriagingAgent.COMPONENT_LABELS`: + +* **Kind:** `bug` (bug reports), `enhancement` (feature requests). +* **Topic:** `documentation`, `question`, `testing`, `sample`, `dependencies`, + `github`. + +adk-java categorizes issue kind via the `bug` / `enhancement` **labels** (not +GitHub's native issue-type field), so this agent applies those labels directly. + +-------------------------------------------------------------------------------- + +## Project Layout + +``` +contrib/samples/github/ +├── GitHubTools.java // Shared kohsuke-based GitHub tools (reused across samples) +└── adktriaging/ + ├── AdkTriagingAgent.java // LlmAgent definition + 3 @Schema-annotated FunctionTools + ├── AdkTriagingAgentRun.java // Entry point: interactive + workflow modes + ├── Settings.java // Environment-variable configuration (lazy accessors) + ├── pom.xml // Maven module config + ├── src/test/java/... // Unit tests for the deterministic logic + └── README.md // This file +``` + +The GitHub Actions workflow lives at +`.github/workflows/triage-adk-java-issues.yml`. + +-------------------------------------------------------------------------------- + +## Interactive Mode + +Use interactive mode locally to dry-run the agent's recommendations before any +changes are made to your repository's issues. + +In this mode the agent's system instruction includes `Only label them when the +user approves the labeling!` — the model will describe its recommendations and +wait for your confirmation before invoking the labeling tools. + +### Required environment variables + +```bash +export GITHUB_TOKEN=ghp_... +export GOOGLE_API_KEY=... +export GOOGLE_GENAI_USE_VERTEXAI=0 +# Optional: +export OWNER=google +export REPO=adk-java +export INTERACTIVE=1 +``` + +### Option A — Console REPL (zero extra setup) + +From the repository root: + +```bash +# Install the ADK libraries + this sample once, then run exec:java scoped to +# this module (exec:java with -am would also run on the parent/core modules, +# which have no mainClass). +./mvnw -pl contrib/samples/github/adktriaging -am install -DskipTests +./mvnw -pl contrib/samples/github/adktriaging exec:java +``` + +The REPL prompts for a request, e.g. `triage the 3 oldest untriaged issues`, +streams every model event back to the terminal, and waits for your approval +before each tool call. + +### Option B — ADK Web UI + +The Java equivalent of Python's `adk web` is the `web` goal of the +[`google-adk-maven-plugin`](https://github.com/google/adk-java/tree/main/maven_plugin). +The goal loads an agent from a static-field reference, so it must run **in this +module's context** (so `AdkTriagingAgent` is on the runtime classpath). From +this module's directory: + +```bash +cd contrib/samples/github/adktriaging +mvn google-adk:web \ + -Dagents=com.example.adktriaging.AdkTriagingAgent.ROOT_AGENT \ + -Dhost=localhost -Dport=8000 +``` + +See the +[plugin README](https://github.com/google/adk-java/tree/main/maven_plugin) for +plugin-prefix setup (e.g. adding `com.google.adk` to your `pluginGroups`, or +invoking the fully-qualified goal). Then open and +pick the `adk_triaging_assistant` agent from the dropdown. The same +approval-based instruction applies. + +-------------------------------------------------------------------------------- + +## Verifying It Works + +Because this agent mutates real GitHub issues, verify it in layers — cheapest +and safest first: + +### 1. Unit tests (no secrets, no network) + +The deterministic logic (label allowlist, rotation parsing, dry-run/placeholder +guards, and the triage-decision filter) is covered by JUnit tests: + +From the repository root: + +```bash +./mvnw -pl contrib/samples/github/adktriaging -am test +``` + +### 2. `DRY_RUN` — full live pipeline, zero writes + +Set `DRY_RUN=1` to exercise the entire pipeline (real Gemini calls, real issue +fetching) while the label/assign tools only **log** what they *would* do and +return a `"dry_run": true` envelope instead of calling GitHub's mutation +endpoints: + +From the repository root: + +```bash +# Install the ADK libs + this sample once (no env vars needed for the build): +./mvnw -q -pl contrib/samples/github/adktriaging -am install -DskipTests + +# Then run exec:java scoped to this module, with the env vars on the exec step +# (exec:java with -am would also run on the parent/core modules, which have no +# mainClass): +GITHUB_TOKEN=… GOOGLE_API_KEY=… GOOGLE_GENAI_USE_VERTEXAI=0 \ +INTERACTIVE=0 EVENT_NAME=schedule ISSUE_COUNT_TO_PROCESS=1 DRY_RUN=1 \ +./mvnw -q -pl contrib/samples/github/adktriaging exec:java +``` + +This is the recommended way to confirm the workflow end-to-end before enabling +real writes. The same command without `DRY_RUN` is exactly what CI runs. + +### 3. `workflow_dispatch` + +Once the workflow is installed, trigger it manually from the Actions tab (it +supports `workflow_dispatch`) and watch the logs — ideally with the `DRY_RUN` +env set to `1` in the workflow for the first run. + +-------------------------------------------------------------------------------- + +## GitHub Workflow Mode + +In workflow mode the agent runs fully unattended: it discovers untriaged issues, +applies labels, and assigns owners — no human confirmation. Triggered by +`INTERACTIVE=0`. + +> **Note:** owner assignment is skipped unless `GTECH_ASSIGNEES` is set (see +> [Environment Variables](#environment-variables)). Until then the agent only +> applies labels: the assignment tool is withheld from the model entirely, so +> the run spends no model/GitHub calls attempting (or retrying) assignments it +> cannot make. + +> **Heads up:** the workflow ships with `DRY_RUN: '1'`, so the first runs only +> *log* the labels/assignees they would apply. Flip it to `'0'` once you've +> confirmed the output looks right. + +### Safety and prompt injection + +Issue titles and bodies are untrusted input fed to the model, so this sample +defends in depth: tools only apply labels from a fixed [allowlist](#labels), +owner assignment is a deterministic round-robin (the model never picks a +person), and the mutating tools are **bound to authorized issues** — in +single-issue mode only the triggering issue, and in batch mode only the issues +returned by `list_untriaged_issues` — so a crafted body cannot steer the agent +into modifying an unrelated issue. The shared `GitHubTools` writes are +additionally pinned to the configured `OWNER`/`REPO`, so untrusted content +cannot redirect a label or assignment to a different repository. **Residual +risk:** a sufficiently clever body could still mislead the *classification* of +its own issue (e.g. nudging `bug` vs. `enhancement`); the blast radius is +bounded to a wrong-but-valid label on that one issue. Keep `DRY_RUN` on until +you trust the output, and review the `permissions:` block before widening the +token's scope. + +### Triggers + +The supplied workflow runs the agent on: + +1. **New issues (`opened`)** — classifies the issue and applies labels. +2. **Schedule (every 6 hours)** — batch-processes up to + `ISSUE_COUNT_TO_PROCESS` (default `3`) untriaged issues to act as a safety + net. +3. **Manual dispatch (`workflow_dispatch`)** — run on demand from the Actions + tab (handy for a first `DRY_RUN` verification). + +### Installation + +The workflow at `.github/workflows/triage-adk-java-issues.yml` is ready to run +in the `adk-java` repository. Set this secret on the repository: + +| Secret | Purpose | +| ---------------- | -------------------------------------------------- | +| `GOOGLE_API_KEY` | Gemini API key for the agent (or wire up Vertex AI | +: : service accounts). : + +Labeling and assignment use the workflow's built-in `GITHUB_TOKEN`, which the +`permissions: issues: write` block scopes appropriately — there is no PAT to +create or rotate. Provide your own PAT (and point `GITHUB_TOKEN` at it in the +workflow) only if you want triage actions attributed to a distinct bot identity. + +### How it runs + +The workflow checks out the repo, installs Temurin Java 17, then runs: + +```bash +# Install the ADK libs + sample, then run exec:java scoped to this module +# (exec:java with -am would also run on the parent/core modules, which have no +# mainClass). +./mvnw -q -pl contrib/samples/github/adktriaging -am install -DskipTests +./mvnw -q -pl contrib/samples/github/adktriaging exec:java +``` + +with the environment variables passed in by the workflow file. + +-------------------------------------------------------------------------------- + +## Environment Variables + +Variable | Required | Default | Purpose +--------------------------- | -------- | ------------------- | ------- +`GITHUB_TOKEN` | Yes | — | PAT with `issues:write`. +`GOOGLE_API_KEY` | Yes\* | — | Gemini API key (\*not required if you use Vertex AI). +`GOOGLE_GENAI_USE_VERTEXAI` | No | `FALSE` | Set to `TRUE` to route Gemini calls through Vertex AI. +`OWNER` | No | `google` | Repository owner. +`REPO` | No | `adk-java` | Repository name. +`MODEL` | No | `gemini-pro-latest` | Gemini model used for triaging (a Pro model favors classification quality). +`INTERACTIVE` | No | `1` | `0`/`false` for unattended workflow mode, `1`/`true` for interactive. +`DRY_RUN` | No | `0` | `1`/`true` logs intended label/assign actions without calling GitHub. +`EVENT_NAME` | No | — | GitHub event name (`issues`, `schedule`, ...).

Owner handles are +**not** hard-coded (adk-java has no public `CODEOWNERS`), so to enable owner +assignment you only need to set one environment variable: + +```bash +export GTECH_ASSIGNEES="handle1,handle2,handle3" +``` + +Issues are assigned round-robin via `issue_number % N`. Until `GTECH_ASSIGNEES` +is set, owner assignment is disabled: the assignment tool is not registered with +the agent and the system instruction tells the model not to assign anyone, so +the agent applies labels and reports that no triagers are configured (without +spending calls retrying an assignment it cannot make). + +If adk-java's label set changes, edit `AdkTriagingAgent.COMPONENT_LABELS` and +the matching `AdkTriagingAgent.LABEL_GUIDELINES` rubric — both are normal +`static final` fields, no other code changes required. diff --git a/contrib/samples/github/adktriaging/Settings.java b/contrib/samples/github/adktriaging/Settings.java new file mode 100644 index 000000000..0de7861ab --- /dev/null +++ b/contrib/samples/github/adktriaging/Settings.java @@ -0,0 +1,165 @@ +// Copyright 2026 Google LLC +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. +package com.example.adktriaging; + +import java.util.Locale; +import java.util.Set; +import org.jspecify.annotations.Nullable; + +/** + * Configuration read from environment variables.

This is the Java port of the Python {@code adk_pr_triaging_agent/agent.py}, adapted to the + * actual label taxonomy of {@code google/adk-java}. The Python agent applies one of ten adk-python + * component labels (e.g. {@code services}, {@code models}, {@code mcp}); those labels do + * not exist in adk-java, so — exactly as the sibling ADK Issue Triaging Agent does — + * this port classifies PRs with adk-java's own labels (see {@link #ALLOWED_LABELS}). + * + *

The agent uses Gemini to: + * + *

    + *
  • recommend a single topic/kind label for each open pull request (e.g. {@code bug}, {@code + * enhancement}, {@code documentation}), + *
  • check the PR against the repository's contribution guidelines and, when it falls short, + * post a single, polite comment asking the author for the missing context. + *
+ * + *

It uses Gemini to analyze each +pull request, recommend a label that actually exists in `adk-java`, and check the +PR against the repository's contribution guidelines — posting a single, polite +comment when something important is missing. + +This sample is the Java port of +[`adk-python/contributing/samples/adk_team/adk_pr_triaging_agent`](https://github.com/google/adk-python/tree/main/contributing/samples/adk_team/adk_pr_triaging_agent), +adapted to the **real label taxonomy of `adk-java`**. The Python agent applies +one of ten adk-python *component* labels (`services`, `models`, `mcp`, …) that do +not exist in `adk-java`, so — exactly like the sibling +[ADK Issue Triaging Agent](../adktriaging) — this port classifies PRs with +`adk-java`'s own labels. + +It is built with the [Google ADK for Java](https://github.com/google/adk-java) +itself and doubles as a community sample: every tool is a real `FunctionTool`, +every JSON envelope matches the Python contract, and the agent runs in both +interactive mode (local CLI / `adk web`) and unattended GitHub Actions workflow +mode. All GitHub access goes through the shared `GitHubTools` (backed by the +[`org.kohsuke:github-api`](https://github-api.kohsuke.org/) client) that this +sample reuses with the ADK Issue Triaging Agent and the ADK Docs Release +Analyzer. + +-------------------------------------------------------------------------------- + +## Triaging Workflow + +For each pull request the agent: + +1. Fetches the PR details (title, body, state, author, labels, changed files, + commits, recent comments, status checks and a truncated diff). +2. **Skips** the PR (no label, no comment) when it is closed or already carries + one of the allowed labels. +3. Otherwise **labels** it with the single most appropriate label and, if the + PR does not meet the contribution guidelines, **comments** asking the author + for the missing context. + +### Labels + +The agent may only apply labels that exist in `google/adk-java`, listed in +`AdkPrTriagingAgent.ALLOWED_LABELS`: + +`bug`, `enhancement`, `documentation`, `testing`, `sample`, `dependencies`, +`github`. + +### Contribution-guideline checks + +The agent embeds the repository's `CONTRIBUTING.md` (read at runtime) plus a +summary of the `adk-java` PR policy, and uses the PR's `status_checks`, +`commit_count`, `body` and `diff` to flag common gaps: + +* missing/failing **CLA** check, +* more than a **single commit**, +* a bug-fix PR with no **linked issue**, +* an insufficient **description**. + +To avoid spamming authors, every comment includes the bolded marker +`Response from ADK PR Triaging Agent`, and the agent is instructed not to comment +again when a comment containing that marker is already present. + +-------------------------------------------------------------------------------- + +## Project Layout + +``` +contrib/samples/github/ +├── GitHubTools.java // Shared kohsuke-based GitHub tools (reused across samples) +└── adkprtriaging/ + ├── AdkPrTriagingAgent.java // LlmAgent definition + 3 @Schema-annotated FunctionTools + ├── AdkPrTriagingAgentRun.java // Entry point: interactive + workflow modes + ├── Settings.java // Environment-variable configuration (lazy accessors) + ├── pom.xml // Maven module config + ├── src/test/java/... // Unit tests for the deterministic logic + └── README.md // This file +``` + +The GitHub Actions workflow lives at +`.github/workflows/pr-triage-adk-java.yml`. + +-------------------------------------------------------------------------------- + +## Interactive Mode + +Use interactive mode locally to dry-run the agent's recommendations before any +changes are made to your repository's pull requests. + +In this mode the agent's system instruction includes `Only label or comment when +the user approves the labeling or commenting!` — the model describes its +recommendations and waits for your confirmation before invoking the +labeling/comment tools. + +### Required environment variables + +```bash +export GITHUB_TOKEN=ghp_... +export GOOGLE_API_KEY=... +export GOOGLE_GENAI_USE_VERTEXAI=0 +# Optional: +export OWNER=google +export REPO=adk-java +export INTERACTIVE=1 +``` + +### Option A — Console REPL (zero extra setup) + +From the repository root: + +```bash +# Install the ADK libraries + this sample once, then run exec:java scoped to +# this module (exec:java with -am would also run on the parent/core modules, +# which have no mainClass). +./mvnw -pl contrib/samples/github/adkprtriaging -am install -DskipTests +./mvnw -pl contrib/samples/github/adkprtriaging exec:java +``` + +The REPL prompts for a request, e.g. `triage pull request #123`, streams every +model event back to the terminal, and waits for your approval before each tool +call. + +### Option B — ADK Web UI + +The Java equivalent of Python's `adk web` is the `web` goal of the +[`google-adk-maven-plugin`](https://github.com/google/adk-java/tree/main/maven_plugin). +The goal loads an agent from a static-field reference, so it must run **in this +module's context** (so `AdkPrTriagingAgent` is on the runtime classpath). From +this module's directory: + +```bash +cd contrib/samples/github/adkprtriaging +mvn google-adk:web \ + -Dagents=com.example.adkprtriaging.AdkPrTriagingAgent.ROOT_AGENT \ + -Dhost=localhost -Dport=8000 +``` + +See the +[plugin README](https://github.com/google/adk-java/tree/main/maven_plugin) for +plugin-prefix setup. Then open and pick the +`adk_pr_triaging_assistant` agent from the dropdown. The same approval-based +instruction applies. + +-------------------------------------------------------------------------------- + +## Verifying It Works + +Because this agent mutates real GitHub pull requests, verify it in layers — +cheapest and safest first: + +### 1. Unit tests (no secrets, no network) + +The deterministic logic (label allowlist, tool wiring, instruction construction, +authorization guard, and the dry-run label/comment short-circuits) is covered by +JUnit tests. From the repository root: + +```bash +./mvnw -pl contrib/samples/github/adkprtriaging -am test +``` + +### 2. `DRY_RUN` — full live pipeline, zero writes + +Set `DRY_RUN=1` to exercise the entire pipeline (real Gemini calls, real PR +fetching) while the label/comment tools only **log** what they *would* do and +return a `"dry_run": true` envelope instead of calling GitHub's mutation +endpoints: + +```bash +# Install the ADK libs + this sample once (no env vars needed for the build): +./mvnw -q -pl contrib/samples/github/adkprtriaging -am install -DskipTests + +# Then run exec:java scoped to this module, with the env vars on the exec step: +GITHUB_TOKEN=… GOOGLE_API_KEY=… GOOGLE_GENAI_USE_VERTEXAI=0 \ +INTERACTIVE=0 PULL_REQUEST_NUMBER=123 DRY_RUN=1 \ +./mvnw -q -pl contrib/samples/github/adkprtriaging exec:java +``` + +This is the recommended way to confirm the workflow end-to-end before enabling +real writes. The same command without `DRY_RUN` is exactly what CI runs. + +### 3. `workflow_dispatch` + +Once the workflow is installed, trigger it manually from the Actions tab (it +supports `workflow_dispatch` with a `pr_number` input) and watch the logs — +ideally with `DRY_RUN` set to `1` for the first run. + +-------------------------------------------------------------------------------- + +## GitHub Workflow Mode + +In workflow mode the agent runs fully unattended: it triages the single pull +request that triggered the workflow — no human confirmation. Triggered by +`INTERACTIVE=0`. + +> **Heads up:** the workflow ships with `DRY_RUN: '1'`, so the first runs only +> *log* the labels/comments they would apply. Flip it to `'0'` once you've +> confirmed the output looks right. + +### Safety and prompt injection + +PR titles, bodies and diffs are untrusted input fed to the model, so this sample +defends in depth: + +* The workflow uses `pull_request_target` but relies on the **default checkout + (the base branch)** and never checks out the PR head, so untrusted PR code is + never executed — the agent only reads the PR through the GitHub API. +* Tools only apply labels from a fixed [allowlist](#labels). +* The mutating tools are **bound to the authorized PR** (the one the workflow + was triggered for), so a crafted body cannot steer the agent into modifying + an unrelated pull request. +* The shared `GitHubTools` writes are pinned to the configured `OWNER`/`REPO`, + so untrusted content cannot redirect a label or comment to a different + repository. + +**Residual risk:** a sufficiently clever body could still mislead the +*classification* of its own PR (e.g. nudging `bug` vs. `enhancement`); the blast +radius is bounded to a wrong-but-valid label, or one extra comment, on that one +PR. Keep `DRY_RUN` on until you trust the output, and review the `permissions:` +block before widening the token's scope. + +### Triggers + +The supplied workflow runs the agent when a PR is `opened`, `reopened`, or +`edited`, and on manual `workflow_dispatch` (with a `pr_number` input). + +### Installation + +The workflow at `.github/workflows/pr-triage-adk-java.yml` is ready to run in the +`adk-java` repository.

Provide your own PAT (and point `GITHUB_TOKEN` at it in the +workflow) only if you want triage actions attributed to a distinct bot identity. + +### How it runs + +The workflow checks out the repo, installs Temurin Java 17, then runs: + +```bash +./mvnw -q -pl contrib/samples/github/adkprtriaging -am install -DskipTests +./mvnw -q -pl contrib/samples/github/adkprtriaging exec:java +``` + +with the environment variables passed in by the workflow file. + +-------------------------------------------------------------------------------- + +## Environment Variables + +Variable | Required | Default | Purpose +--------------------------- | -------- | ------------------- | ------- +`GITHUB_TOKEN` | Yes | — | PAT with `pull_requests:write`. +`GOOGLE_API_KEY` | Yes\* | — | Gemini API key (\*not required if you use Vertex AI). +`GOOGLE_GENAI_USE_VERTEXAI` | No | `FALSE` | Set to `TRUE` to route Gemini calls through Vertex AI. +`OWNER` | No | `google` | Repository owner. +`REPO` | No | `adk-java` | Repository name. +`MODEL` | No | `gemini-pro-latest` | Gemini model used for triaging (a Pro model favors classification quality). +`INTERACTIVE` | No | `1` | `0`/`false` for unattended workflow mode, `1`/`true` for interactive. +`DRY_RUN` | No | `0` | `1`/`true` logs intended label/comment actions without calling GitHub. +`PULL_REQUEST_NUMBER` | No | — | The PR to triage in workflow mode (set by GitHub Actions). +`EVENT_NAME` | No | — | GitHub event name (logged for diagnostics). +`CONTRIBUTING_MD_PATH` | No | `CONTRIBUTING.md` | Path to the repo's `CONTRIBUTING.md`, embedded in the instruction.
