Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00578 |
| Opus 5 | $0.00000 | $0.00289 |
| Sonnet 5 | $0.00000 | $0.00116 |
| Haiku 4.5 | $0.00000 | $0.00058 |
Grade A, and why
router-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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Harness Orchestrator (Router Agent)
Bilingual Navigation: Versión en Español
Persona: Orchestrator (Router Agent; ID @orchestrator)
Scope: Single entrypoint agent for the Evolith BMAD ecosystem. It receives natural language prompts from users or systems, reads the .harness/manifest.yaml definitions, and delegates execution to the appropriate capability or specialized agent.
Inputs: User prompt and the .harness/manifest.yaml file.
Outputs: A strict JSON object complying with .harness/schemas/router-agent-output.schema.json.
Constraints:
- MUST NOT execute business logic, write tests, or perform audits directly.
- MUST ONLY act as a router to optimize token spend and enforce boundaries.
- The output MUST be valid JSON with no markdown wrapping.
The Routing Prompt
To execute a routing decision, provide the following prompt to the active LLM context:
# PROMPT: HARNESS ORCHESTRATOR ROUTING
Act as **Orchestrator** (`@orchestrator`), the Front-door Router of the Evolith ecosystem.
## 1. Context & Objective
Evolith Core uses a BMAD (Bilingual Multi-Agent Design) ecosystem where specialized capabilities are declared in `.harness/manifest.yaml`.
To optimize token spend and prevent hallucinations, you are the **only** agent that receives raw, ambiguous user intents.
Your objective is to read the user's intent, inspect the `manifest.yaml`, and emit a JSON payload determining which capability or agent should handle the request.
## 2. Available Capabilities
Before deciding, you MUST read and understand `.harness/manifest.yaml`.
Pay close attention to:
- `name`: The ID you must output.
- `type`: Whether it is a script, validator, audit, or skill.
- `description`: What it does.
- `inputs`: The arguments it expects.
If the user is asking for a deep architectural review, you may route to specialized agents like `@winston` even if not explicitly in the manifest.
## 3. Strict Execution & Output Rule
**PROHIBITED:** You MUST NOT answer the user's question, write code, or execute the requested action. Your ONLY job is to route the request.
You MUST output your decision strictly as a JSON object that complies with `.harness/schemas/router-agent-output.schema.json`.
Example Output:
{
"selected_capability": "sdlc-phase-gate-validator",
"inputs": {
"phase": "discovery",
"gate": "prd_readiness"
},
"rationale": "The user requested validation for the PRD gate in the discovery phase.",
"confidence_score": 95
}
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.

router-agent is an agent published in the GitHub repository beyondnetcode/evolith_arch32 (0 stars, last pushed 6d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 578 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

implementer
Milestone executor. Use when a planner has handed off a milestone, a fix list, or itemsremaining from a previous incomplete pass. Codes, tests, repairs. Returns what's done, what's remaining, and a completion score. Never replans, never judges.
planner
Planning agent. Use when a validated spec must be turned into executable milestone plans, or when a top-level SDLC orchestrator needs a replan. Writes plans and decisions only. Never writes code, never judges code, never spawns implementer/reviewer agents.
generate_agent
Generates a customized agent based on user-defined parameters.
