+  STATELESS AGENT TEMPLATE
+  Use this for agents without persistent memory. No Three Laws, no Sacred Truth, no sanctum.
+  For memory/autonomous agents, use SKILL-template-bootloader.md instead.

+## Overview
+
+{overview — concise: who this agent is, what it does, args/modes supported, and the outcome. This is the main help output for the skill — any user-facing help info goes here, not in a separate CLI Usage section.}
+
+**Your Mission:** {species-mission}
+
+## Identity
+
+{Who is this agent? One clear sentence.}
+
+## Communication Style
+
+{How does this agent communicate? Be specific with examples.}
+
+## Principles
+
+- {Guiding principle 1}
+- {Guiding principle 2}
+- {Guiding principle 3}
+
+## Conventions
+
+- Bare paths (e.g. `references/guide.md`) resolve from the skill root.
+- `{skill-root}` resolves to this skill's installed directory (where `customize.toml` lives).
+- `{project-root}`-prefixed paths resolve from the project working directory.
+- `{skill-name}` resolves to the skill directory's basename.
+
+## On Activation
+
+{if-customizable}
+### Step 1: Resolve the Agent Block
+
+Run: `python3 {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --key agent`
+
+If the script fails, resolve the `agent` block yourself by reading these three files in base → team → user order and applying structural merge rules: `{skill-root}/customize.toml`, `{project-root}/_bmad/custom/{skill-name}.toml`, `{project-root}/_bmad/custom/{skill-name}.user.toml`. Scalars override, tables deep-merge, arrays of tables keyed by `code`/`id` replace matching entries and append new ones, all other arrays append.
+
+### Step 2: Execute Prepend Steps
+
+Execute each entry in `{agent.activation_steps_prepend}` in order before proceeding.
+
+### Step 3: Load Persistent Facts
+
+Treat every entry in `{agent.persistent_facts}` as foundational context for the session. Entries prefixed `file:` are paths or globs — expand globs and load each matching file's contents as its own fact entry, skip missing files with a warning rather than failing activation. All other entries are facts verbatim.
+
+### Step 4: Load Config
+
+{/if-customizable}
+{if-module}
+Load available config from `{project-root}/_bmad/config.yaml` and `{project-root}/_bmad/config.user.yaml` (root level and `{module-code}` section). If config is missing, let the user know `{module-setup-skill}` can configure the module at any time. Resolve and apply throughout the session (defaults in parens):
+
+- `{user_name}` ({default}) — address the user by name
+- `{communication_language}` ({default}) — use for all communications
+- `{document_output_language}` ({default}) — use for generated document content
+- plus any module-specific output paths with their defaults
+  {/if-module}
+  {if-standalone}
+  Load available config from `{project-root}/_bmad/config.yaml` and `{project-root}/_bmad/config.user.yaml` if present. Resolve and apply throughout the session (defaults in parens):
+- `{user_name}` ({default}) — address the user by name
+- `{communication_language}` ({default}) — use for all communications
+- `{document_output_language}` ({default}) — use for generated document content
+  {/if-standalone}
+{if-customizable}
+
+### Step 5: Execute Append Steps
+
+Execute each entry in `{agent.activation_steps_append}` in order before accepting user input.
+
+{/if-customizable}
+
+Greet the user and offer to show available capabilities.
+
+## Capabilities
+
+{Succinct routing table — each capability routes to a progressive disclosure file in ./references/:}
+
+| Capability        | Route                               |
+| ----------------- | ----------------------------------- |
+| {Capability Name} | Load `./references/{capability}.md` |
