Subject: [PATCH 1/9] feat(nemo-agents): add Fabric (spec-v1) email-phishing
 example

Port the email-phishing analyzer to a Platform-native nemo-agents-spec-v1
agent: a deepagents orchestrator that delegates classification to a phishing
subagent and calls a deterministic extract_iocs MCP tool. The prompt and
model live in agent.yaml (tunable) and each step emits a trace span, replacing
the opaque MCP-proxy classifier.

- extract_iocs ported as a stdio MCP console tool (pure regex, unit-tested)
- sender-inclusive input: assembled From:/Subject:/body 'email' column so the
  sender (a top phishing tell) reaches the model and extract_iocs
- eval config uses question_key: email
- registered as a workspace member so its package resolves

ASTD-370, ASTD-371, ASTD-372

+# Email Phishing Analyzer — Fabric example (`nemo-agents-spec-v1`)
+
+A Platform-native port of the email-phishing analyzer. Unlike the NAT ReAct
+example (`../email-phishing-analyzer`), the classification does **not** hide
+behind an opaque MCP server. It runs as a Fabric **deepagents orchestrator** that
+delegates the verdict to a phishing **subagent** and calls a deterministic
+`extract_iocs` **tool** — so the prompt and model are tunable in config, and each
+step (subagent task + tool call) emits a trace span.
+
+## Shape
+
+```
+orchestrator (deepagents)  ── delegates ──▶  phishing-analyzer subagent
+      │                                            │
+      └──────────── calls ──────────────▶  extract_iocs (stdio MCP tool)
+```
+
+- **`agent.yaml`** — the `nemo-agents-spec-v1` config. Orchestrator triage prompt
+  in `instructions.system`; the phishing subagent under
+  `harnesses.deepagents.settings.deepagents.subagents`, with its own
+  `system_prompt` and a loose YAML verdict (`is_likely_phishing`, `confidence`,
+  `indicators`, `explanation`) the orchestrator parses; `extract_iocs` wired as a
+  `harness_native` stdio MCP server.
+- **`src/email_phishing_fabric/`** — the `extract_iocs` MCP tool. Pure-regex
+  URL/domain extraction (ported from the email-security-analyst example), served
+  over stdio by the `email-phishing-iocs-mcp` console script.
+- **`data/`** — `smaller_test.csv` plus `build_dataset.py`, which assembles a
+  sender-inclusive `email` column (`From:`/`Subject:`/body). The sender is a top
+  phishing tell and also feeds `extract_iocs`; the NAT eval dropped it by feeding
+  `body` only.
+- **`email-phishing-eval.yml`** — eval config; `question_key: email` (the
+  assembled message, not bare `body`).
+
+## Tune
+
+- **Prompts:** edit `instructions.system.content` (orchestrator) or the subagent
+  `system_prompt` in `agent.yaml`.
+- **Hyperparameters:** `models.default.temperature` (and `settings`). Add a
+  per-subagent `model: <provider>:<model>` to tune the analysis step
+  independently of the orchestrator.
+
+## Run
+
+`extract_iocs` must be importable in the deploy venv, so install this example
+first (its console script is referenced by `agent.yaml`):
+
+```bash
+uv pip install plugins/nemo-agents/examples/email-phishing-fabric
+```
+
+Then create / deploy / invoke (deepagents adapter + `NVIDIA_API_KEY` required):
+
+```bash
+nemo agents create  --name email-phishing-fabric \
+  --agent-config plugins/nemo-agents/examples/email-phishing-fabric/agent.yaml
+nemo agents deploy  --agent email-phishing-fabric --name email-phishing-fabric-deployment
+nemo agents invoke  --agent-deployment email-phishing-fabric-deployment \
+  --input "From: it-support@paypa1-secure.example\nSubject: Verify your account\n\nYour account is locked. Confirm your password at http://paypa1-secure.example/login"
+```
+
+Evaluate against the sender-inclusive dataset:
+
+```bash
+nemo agents evaluate run \
+  --eval-config plugins/nemo-agents/examples/email-phishing-fabric/email-phishing-eval.yml \
+  --agent email-phishing-fabric
+```
+
+## Status
+
+Structurally validated: `agent.yaml` passes `AgentConfig` (`nemo-agents-spec-v1`)
+and translates to a typed Fabric config; `extract_iocs` is unit-tested. A live
+create/deploy/invoke against a running Platform (with `NVIDIA_API_KEY`) is the
+next step and is not exercised here. Eval judge weights/prompt are starters —
+tune per your evaluator plugin.

Subject: [PATCH 2/9] docs(nemo-agents): correct email-phishing-fabric deploy
 paths
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The extract_iocs stdio MCP tool is a console script that Fabric launches as a
parallel child process, resolving the command on PATH. The runtime that must
contain it differs by deploy mode:

- subprocess (default): runs locally from the repo .venv (sys.executable,
  inherits PATH); the example is a workspace member so uv sync --all-packages
  already provides the console script — no image needed.
- docker/k8s: the container lacks the package; bake it in with
  nemo agents package --pyproject (uv pip install .), then deploy --mode
  docker/k8s --image (--publish --registry for k8s).

Replaces the misleading local 'uv pip install + bare deploy' instruction and
the agent.yaml comment. Addresses review P1 (deployed agent could not start
its MCP server under container modes).

 ## Run
 
-`extract_iocs` must be importable in the deploy venv, so install this example
-first (its console script is referenced by `agent.yaml`):
+`extract_iocs` runs as a **stdio MCP server that Fabric launches as a parallel
+child process** of the agent: the deepagents adapter expands and `shlex`-splits
+the `url`, then spawns it, resolving the command on `PATH`. So the console
+script must exist in the environment the agent actually runs in — which differs
+by deployment mode. (deepagents adapter + `NVIDIA_API_KEY` required either way.)
 
-```bash
-uv pip install plugins/nemo-agents/examples/email-phishing-fabric
-```
+### Local (`--mode subprocess`, the default)
 
-Then create / deploy / invoke (deepagents adapter + `NVIDIA_API_KEY` required):
+This example is a uv workspace member, so `uv sync --all-packages` already
+installed `email-phishing-iocs-mcp` into the repo `.venv`. The subprocess
+deployment runs from that same venv (`sys.executable`) and inherits its `PATH`,

+
+### Container (`--mode docker` / `k8s`)
+
+A deployment container does **not** have this example installed, so a local
+`uv pip install` cannot reach it. Bake the package into an image with
+`nemo agents package` — project mode (`--pyproject`) runs `uv pip install .`,
+which provides the `email-phishing-iocs-mcp` console script — then deploy that
+image:
+
+```bash
+nemo agents package \

+nemo agents deploy \
+  --agent email-phishing-fabric \
+  --name email-phishing-fabric-deployment \
+  --mode docker \
+  --image email-phishing-fabric:local
 ```
 
+For Kubernetes, publish the image

Subject: [PATCH 3/9] refactor(nemo-agents): relocate email-phishing example
 under nemo-agent-config/
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move the Fabric (spec-v1) email-phishing example from the top-level examples
dir into nemo-agent-config/email-phishing-agent/, alongside calculator-agent —
that directory is where nemo-agents-spec-v1 (Fabric) examples live; the
top-level dir holds NAT examples. Adopt the sibling's conventions:

- flat mcps/ package (mcps.iocs) instead of src/ layout; extract_iocs util +
  FastMCP server combined; console script email-phishing-iocs
- package nemo-agent-config-example-email-phishing; mcp>=1.28.1,<2
- agent renamed email-phishing-agent; mcp url email-phishing-iocs (default
  harness_native exposure); ATOF telemetry like the sibling
- build_dataset.py source path fixed for the new depth

Addresses review: the -fabric suffix was redundant and the example was
misfiled at the top level.

 # Email Phishing Agent — Fabric example (`nemo-agents-spec-v1`)
 
-A Platform-native port of the email-phishing analyzer, and a sibling to
-[`../calculator-agent`](../calculator-agent). Unlike the NAT ReAct example
-(`../../email-phishing-analyzer`), classification does **not** hide behind an
-opaque MCP server. It runs as a Fabric **deepagents orchestrator** that
-delegates the verdict to a phishing **subagent** and calls a deterministic
-`extract_iocs` **tool** — so the prompt and model are tunable in config, and each
-step (subagent task + tool call) emits a trace span.
-
-## Shape
+A DeepAgents **orchestrator** that delegates the verdict to a phishing
+**sub-agent**, which calls a deterministic **`extract_iocs`** tool. Prompt and
+model live in `agent.yaml` (tunable); every step emits a trace span.
 
 ```
-orchestrator (deepagents)  ── delegates ──▶  phishing-analyzer subagent
-      │                                            │
-      └──────────── calls ──────────────▶  extract_iocs (stdio MCP tool)
+orchestrator (deepagents) ── delegates ──▶ phishing-analyzer sub-agent
+      └───────────── calls ─────────────▶ extract_iocs (stdio MCP tool)
 ```
 
-- **`agent.yaml`** — the `nemo-agents-spec-v1` config. Orchestrator triage prompt
-  in `instructions.system`; the phishing subagent under
-  `harnesses.deepagents.settings.deepagents.subagents`, with its own
-  `system_prompt` and a loose YAML verdict (`is_likely_phishing`, `confidence`,
-  `indicators`, `explanation`) the orchestrator parses; `extract_iocs` wired as a
-  stdio MCP server.
-- **`mcps/iocs.py`** — the `extract_iocs` tool: pure-regex URL/domain extraction
-  (ported from the email-security-analyst example), served over stdio by the
-  `email-phishing-iocs` console script.
-- **`data/`** — `smaller_test.csv` plus `build_dataset.py`, which assembles a
-  sender-inclusive `email` column (`From:`/`Subject:`/body). The sender is a top
-  phishing tell and also feeds `extract_iocs`; the NAT eval dropped it by feeding
-  `body` only.
-- **`email-phishing-eval.yml`** — eval config; `question_key: email` (the
-  assembled message, not bare `body`).
-
-## Tune
+## Parts
 
-- **Prompts:** edit `instructions.system.content` (orchestrator) or the subagent
-  `system_prompt` in `agent.yaml`.
-- **Hyperparameters:** `models.default.temperature` (and `settings`). Add a
-  per-subagent `model: <provider>:<model>` to tune the analysis step
-  independently of the orchestrator.
+| Path | What | Why |
+|---|---|---|
+| `agent.yaml` | The `nemo-agents-spec-v1` config: harness, sub-agent, model, MCP server, telemetry | The single tunable surface — prompts + hyperparameters |
+| `mcps/iocs.py` | `extract_iocs` (pure regex) + FastMCP stdio server | The one real tool; URL/domain extraction incl. the sender |
+| `pyproject.toml` | Packages `mcps/`; exposes console `email-phishing-iocs` | Makes the tool resolvable at runtime |
+| `data/smaller_test.csv` | Labeled emails with an assembled `email` column (`From:`/`Subject:`/body) | Eval input; keeps the sender (a top phishing tell) |
+| `data/build_dataset.py` | Rebuilds that column from the upstream NAT dataset | Regenerate after changing the assembly |
+| `email-phishing-eval.yml` | Eval config; `question_key: email` | Scores verdicts against the `label` column |
+| `tests/test_extract_iocs.py` | Unit tests for the tool | Guards the extractor |
 
-## Run
+## Port it (to your own agent)
 
-`extract_iocs` runs as a **stdio MCP server that Fabric launches as a parallel
-child process** of the agent: the deepagents adapter expands and `shlex`-splits
-the `url`, then spawns it, resolving the command on `PATH`. So the console
-script must exist in the environment the agent actually runs in — which differs
-by deployment mode. (deepagents adapter + `NVIDIA_API_KEY` required either way.)
+1. **Copy** this directory to `nemo-agent-config/<your-agent>/`.
+2. **Rename** in `pyproject.toml` (`name`, `[project.scripts]` console), `agent.yaml` (`name`, `project`, and `mcp.servers.<n>.url` → your console), and your tool in `mcps/`.
+3. **Register** as a workspace member: add the path to root `pyproject.toml` `members`, then `uv sync --all-packages` (installs your console into `.venv` for local runs).
+4. **Point** `data/` + `email-phishing-eval.yml` at your dataset.
 
-### Local (`--mode subprocess`, the default)
+## Use it in Platform (CLI)
 
-This example is a uv workspace member, so `uv sync --all-packages` already
-installed `email-phishing-iocs` into the repo `.venv`. The subprocess deployment
-runs from that same venv (`sys.executable`) and inherits its `PATH`, so Fabric
-can spawn the tool — no extra install and no image needed:
+Prereqs: platform up (`NMP_BASE_URL=http://localhost:8080`), `NVIDIA_API_KEY` set, `uv sync --all-packages` done.
 
-```bash
-nemo agents create  --name email-phishing-agent \
-  --agent-config plugins/nemo-agents/examples/nemo-agent-config/email-phishing-agent/agent.yaml
-nemo agents deploy  --agent email-phishing-agent --name email-phishing-agent-deployment --mode subprocess
-nemo agents invoke  --agent-deployment email-phishing-agent-deployment \
-  --input "From: it-support@paypa1-secure.example
-Subject: Verify your account
-
-Your account is locked. Confirm your password at http://paypa1-secure.example/login"
-```
+1. **Register** — `nemo agents create --name email-phishing-agent --agent-config plugins/nemo-agents/examples/nemo-agent-config/email-phishing-agent/agent.yaml`
+2. **Deploy** — `nemo agents deploy --agent email-phishing-agent --name email-phishing-agent-deployment --mode subprocess` (for `docker`/`k8s`, first `nemo agents package --pyproject <this>/pyproject.toml --tag <img>`, then deploy `--mode docker --image <img>`).
+3. **Invoke** — `nemo agents invoke --agent-deployment email-phishing-agent-deployment --input "<full email>"` → a YAML verdict.
+4. **Observe** — `nemo agents logs --agent email-phishing-agent`; the `extract_iocs` call lands in `artifacts/.../events.atof.jsonl` (`category: tool`).
+5. **Tune & evaluate** — edit `agent.yaml` (sub-agent `system_prompt`, `models.default.temperature`), re-deploy, then `nemo agents evaluate run --eval-config <this>/email-phishing-eval.yml --agent email-phishing-agent`.
 
-### Container (`--mode docker` / `k8s`)
+## Use it in Studio
 
-A deployment container does **not** have this example installed, so a local
-`uv pip install` cannot reach it. Bake the package into an image with
-`nemo agents package` — project mode (`--pyproject`) runs `uv pip install .`,
-which provides the `email-phishing-iocs` console script — then deploy that image:
-
-```bash
-nemo agents package \
-  --agent plugins/nemo-agents/examples/nemo-agent-config/email-phishing-agent/agent.yaml \
-  --pyproject plugins/nemo-agents/examples/nemo-agent-config/email-phishing-agent/pyproject.toml \
-  --tag email-phishing-agent:local
-
-nemo agents create  --name email-phishing-agent \
-  --agent-config plugins/nemo-agents/examples/nemo-agent-config/email-phishing-agent/agent.yaml
-nemo agents deploy \
-  --agent email-phishing-agent \
-  --name email-phishing-agent-deployment \
-  --mode docker \
-  --image email-phishing-agent:local
-```
+Prereqs: same platform + key; Studio with Intake on (`VITE_FF_INTAKE_ENABLED=true`), at `…/studio/workspaces/default`.
 
-For Kubernetes, publish the image
-(`nemo agents package ... --publish --registry <registry>`) and pass the
-published image to `nemo agents deploy --mode k8s --image <image>`.
-
-Evaluate against the sender-inclusive dataset:
-
-```bash
-nemo agents evaluate run \
-  --eval-config plugins/nemo-agents/examples/nemo-agent-config/email-phishing-agent/email-phishing-eval.yml \
-  --agent email-phishing-agent
-```
-
-Regenerate the dataset from the upstream NAT example after changing the assembly:
-
-```bash
-uv run python plugins/nemo-agents/examples/nemo-agent-config/email-phishing-agent/data/build_dataset.py
-```
+1. **Register** — Agents → *Create Example* → the `email-phishing-agent` tile. **Pending (ASTD‑08)**; until it lands, register via the CLI (left), then manage it here.
+2. **Deploy** — from the agent's page. **Pending the same tile**; deploy via the CLI today.
+3. **Invoke** — open the deployed agent → Chat → paste the email → read the verdict.
+4. **Observe** — Intake → Traces → open the run: orchestrator → `phishing-analyzer` → `extract_iocs` spans.
+5. **Tune & evaluate** — edit `agent.yaml` and re-deploy (CLI), then Run Evaluation → `smaller_test.csv` for the accuracy score.

Subject: [PATCH 6/9] docs(nemo-agents): restructure email-phishing README as a
 Diataxis tutorial

Single-quadrant tutorial (prerequisites-first, numbered steps with expected
outcomes, Next Steps) mirroring the calculator-agent sibling; plain markdown
(these example READMEs render on GitHub, not Sphinx, so no MyST tab-sets). Move
the 'swap it for your own' how-to into CUSTOMIZE.md, cross-linked from Next
Steps. Addresses CodeRabbit Diataxis/prereqs/next-steps/fence/quoting findings.

+# How to adapt this example for your own agent
+
+**Goal:** turn the email-phishing example into your own agent — a DeepAgents
+orchestrator that delegates to a sub-agent and calls your tool.
+
+**Prerequisites:** you can deploy and invoke the example ([README.md](README.md)).
+
+The shape you're reusing:
+
+```text
+orchestrator (deepagents) ── delegates ──▶ <your> sub-agent
+      └───────────── calls ─────────────▶ <your tool> (stdio MCP)
+```
+
+## Parts & what to change
+
+| Path | What it is | Swap for your own |
+|---|---|---|
+| `agent.yaml` | The `nemo-agents-spec-v1` config: harness, sub-agent, model, MCP server, telemetry | Rewrite the orchestrator `instructions.system` and the sub-agent `system_prompt` + `description`; set `models.default` (+ `temperature`); rename `name` / `telemetry.project` |
+| `mcps/iocs.py` | `extract_iocs` (pure regex) + a FastMCP stdio server | Replace the function body with your tool's logic; keep the `@mcp.tool()` wrapper + `main()`. Rename the module and tool |
+| `pyproject.toml` | Packages `mcps/`; exposes console `email-phishing-iocs` | Set `name` and `[project.scripts] <console> = "mcps.<module>:main"` |

+| `email-phishing-eval.yml` | Eval config (`question_key: email`, `answer_key: label`, `id_key: subject`) | Point the keys at your columns; tune the judge weights/prompt |
+| `tests/test_extract_iocs.py` | Unit tests for the tool | Rewrite for your tool's contract |
+
+## Keep in sync
+
+Two couplings break silently if you rename one side only:
+
+- **Console name:** `pyproject.toml` `[project.scripts]` **must equal** `agent.yaml` → `mcp.servers.<name>.url`.
+- **Workspace member:** add your directory to the **root** `pyproject.toml` `members`, then `uv sync --all-packages` — this installs the console so `--mode subprocess` can launch it.
+
+Keep the `mcps/` directory name (a shared namespace across examples); rename the *module* inside it and the console, not the directory. `id_key` (default `subject`) must be unique across your rows — `build_dataset.py` fails generation on duplicates.
+
+## Steps
+
+1. **Copy** this directory to `nemo-agent-config/<your-agent>/` — a working starting point.
+2. **Rename** the identifiers above (`pyproject.toml`, `agent.yaml`, the module) — keep the console name in sync.
+3. **Register:** add your directory to the root `pyproject.toml` `members`, then `uv sync --all-packages` — the console lands on `PATH`.
+4. **Swap the tool** in `mcps/<module>.py` and update `tests/` — your logic runs.
+5. **Swap the brains:** the orchestrator `instructions.system` and the sub-agent `system_prompt` / `model` — your domain.
+6. **Swap the data** and the eval keys — your evaluation set.
+
+Re-run the [README.md](README.md) tutorial against your agent name to validate.
+

+
+- **Config reference:** the `nemo-agent-config` skill (authoring + validation for `nemo-agents-spec-v1`).

-# Email Phishing Agent — Fabric example (`nemo-agents-spec-v1`)

-A DeepAgents **orchestrator** that delegates to a phishing **sub-agent**, which
-calls a deterministic **`extract_iocs`** tool. The *shape* is the template —
-copy it, then swap the domain pieces below for your own agent.
+Deploy a Fabric (`nemo-agents-spec-v1`) agent end to end and watch it classify a
+phishing email. The agent is a DeepAgents orchestrator that delegates the verdict
+to a phishing sub-agent, which calls a deterministic `extract_iocs` tool.
 
-```
-orchestrator (deepagents) ── delegates ──▶ phishing-analyzer sub-agent
-      └───────────── calls ─────────────▶ extract_iocs (stdio MCP tool)
-```
+**What you'll do:** deploy the example, send it an email, read the verdict, find
+the tool call in the trace, and score it against labeled data.
+
+**Time:** ~5 minutes.
+
+**Prerequisites:**
+
+- NeMo Platform running locally (see [SETUP.md](../../../../../SETUP.md)); `export NMP_BASE_URL=http://localhost:8080`.
+- `export NVIDIA_API_KEY=<your key>`.
+- Dependencies synced from the repo root: `uv sync --all-packages` (installs the `email-phishing-iocs` tool this agent calls).
 
-## Parts & what to swap

+nemo agents deploy --agent email-phishing-agent \
+  --name email-phishing-agent-deployment --mode subprocess
+```
 
-## Keep in sync
+The deploy command waits until the deployment reports `running` on a loopback port.
 
-Two couplings break silently if you rename one side only:
+## Step 2: Classify an email
 
-- **Console name:** `pyproject.toml [project.scripts]` **must equal** `agent.yaml` → `mcp.servers.<name>.url`.
-- **Workspace member:** add your directory to the **root** `pyproject.toml` `members`, then `uv sync --all-packages` — this installs the console so `--mode subprocess` can launch it.
+```bash
+nemo agents invoke --agent-deployment email-phishing-agent-deployment \
+  --input $'From: it-support@paypa1-secure.example\nSubject: Verify your account\n\nYour account is locked. Confirm your password at http://paypa1-secure.example/login'
+```
 
-Keep the `mcps/` package directory as-is (its name is a shared namespace across examples); rename the *module* inside it and the console, not the directory.
+The agent returns a YAML verdict with `is_likely_phishing: true` and lists the
+lookalike sender domain (`paypa1-secure.example`) among its indicators.
 
-## Run it (to validate your swap)
+## Step 3: Find the tool call in the trace
 
-Prereqs: platform up (`NMP_BASE_URL=http://localhost:8080`), `NVIDIA_API_KEY` set, `uv sync --all-packages` done. Studio also needs Intake on (`VITE_FF_INTAKE_ENABLED=true`).
+```bash
+nemo agents logs --agent email-phishing-agent
+```
 
-**Platform (CLI)**
-1. **Register** — `nemo agents create --name <agent> --agent-config <dir>/agent.yaml`
-2. **Deploy** — `nemo agents deploy --agent <agent> --name <agent>-deployment --mode subprocess`
-3. **Invoke** — `nemo agents invoke --agent-deployment <agent>-deployment --input "<sample>"`
-4. **Observe** — `nemo agents logs --agent <agent>`; your tool call lands in `artifacts/.../events.atof.jsonl`
-5. **Evaluate** — `nemo agents evaluate run --eval-config <dir>/email-phishing-eval.yml --agent <agent>`
+The deployment's `artifacts/.../events.atof.jsonl` records an `extract_iocs` tool
+call — evidence the orchestrator delegated to the sub-agent and the tool ran, not
+the model guessing. With NeMo Studio Intake enabled (`VITE_FF_INTAKE_ENABLED=true`),
+the same run appears under **Traces**.
 
-**Studio**
-1. **Register** — Agents → *Create Example* tile. **Pending (ASTD‑08)**; register via the CLI, then manage here.
-2. **Deploy** — from the agent's page. **Pending the same tile**; deploy via the CLI today.
-3. **Invoke** — open the deployed agent → Chat → send your sample.
-4. **Observe** — Intake → Traces → open the run: orchestrator → sub-agent → tool spans.
-5. **Evaluate** — Run Evaluation → your dataset for the accuracy score.
+## Step 4: Evaluate against labeled emails
+
+```bash
+nemo agents evaluate run \
+  --eval-config plugins/nemo-agents/examples/nemo-agent-config/email-phishing-agent/email-phishing-eval.yml \
+  --agent email-phishing-agent
+```
 
-For a container deploy instead of subprocess: `nemo agents package --agent <dir>/agent.yaml --pyproject <dir>/pyproject.toml --tag <img>`, then `deploy --mode docker --image <img>`.
+The judge scores each verdict against the `label` column in
+`data/smaller_test.csv` and prints an accuracy score.
 
-## Status
+## Next Steps
 
-Live-validated for `--mode subprocess` (deploy → invoke → correct verdict; trace + tool call confirmed). Not yet exercised: container packaging, the Studio *Create Example* tile (ASTD‑08), and eval judge tuning (weights/prompt are starters).
+- **Make it your own:** [CUSTOMIZE.md](CUSTOMIZE.md) — swap the tool, prompts, model, and data for your own agent.
+- **Container deploys (docker/k8s):** [docs/agents/deploy-agents.mdx](../../../../../docs/agents/deploy-agents.mdx).
+- **Compare with/without a tool:** the sibling [calculator-agent](../calculator-agent) example.

Subject: [PATCH 8/9] chore(nemo-agents): add relay ATIF->Intake telemetry to
 email-phishing-agent

WIP toward ASTD-385. Adds an atif http-storage sink pointing at the local
Intake ingest endpoint, alongside the existing atof file sink. Note: this does
not yet produce Intake spans for the in-process DeepAgents harness (only local
ATOF is emitted today); tracked in ASTD-385. Endpoint is hardcoded to the local
Intake (127.0.0.1:8080), matching the sibling agent-relay-intake.yaml.

Subject: [PATCH 9/9] test(nemo-agents): assert exact domain lists in
 extract_iocs tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CodeQL flagged three `"host" in result["domains"]` assertions as *Incomplete URL
substring sanitization*. They are list-membership checks, not sanitization —
`extract_iocs` returns sorted lists — but CodeQL cannot infer the dict value type.

Assert exact list equality instead, matching the other tests in this file. The
assertions get stronger (order + full contents) and the flagged pattern is gone.
