Single Agent Builder

Mission

Create one installable Agentlas worker package. The output may include multiple skills, setup guides, memory contracts, runtime adapters, research refresh, and self-evolution proposals, but it remains a single agent package.

Use When

• The user asks for one agent, helper, worker, specialist, or personal tool.
• The agent may need several skills but does not need a roster or team topology.
• The user asks for self-evolving, keeps-learning, latest/current research, or

periodic refresh behavior.

Builder Interview and Research Gate

Before writing the single worker, run `contracts/builder-interview-research-gate.md`. Do not accept a vague one-line agent idea as the final prompt. Assess supplied context first; ask only real gaps, including zero questions when sufficient (8-12 only if that many gaps remain), until the worker's target user, recurring tasks, inputs, outputs, tools/plugins, examples, failure modes, memory policy, and evaluation rubric are clear.

Research the domain before writing `agent.md` or reusable skills. Use official or primary docs, similar agent repositories or comparables, GitHub examples, academic/professional theory, and plugin documentation for selected tools. Record accepted and rejected tool or plugin choices with permission, secret, fallback, and smoke-test notes. Write `docs/domain-expert-synthesis.md` before the final worker prompt so interview answers, repo patterns, theory, and tool choices become concrete specialist behavior.

Must Include

• Runtime instruction files must be written in English. This includes

`AGENTS.md`, `CLAUDE.md`, `GEMINI.md`, `agent.md`, skill instructions, workflow/command adapters, handoff contracts, and operating docs. Translate Korean or other-language source material into English behavior before writing the package. Localized public copy and trigger examples may use the target user language.

• `AGENTS.md` as canonical core.
• `.agents/<agent-id>/agent.md` or equivalent single worker contract.
• `.agents/skills/<skill-id>/SKILL.md` for reusable capabilities.
• `docs/builder-interview.md`.
• `docs/research-sources.md`.
• `docs/tool-selection.md`.
• `docs/domain-expert-synthesis.md`.
• `docs/prompt-performance-contract.md`.
• `.agentlas/capability-eval-plan.json`.
• `.agentlas/agent-card.json`.
• `.agentlas/company-blueprint.json` with `single-agent` topology unless the

user explicitly asks for a team.

• `.agentlas/memory-map.json`, `.agentlas/memory-tickets.jsonl`, and

`.agentlas/vault-references.json`.

• `.agentlas/mcp-policy.json` with system-global-first catalog resolution,

one-pass consent, per-requirement degradation, and no server command, args, endpoint, or credential value.

• Runtime adapters for requested targets.
• `.agentlas/global-commands.json`.
• One canonical global command for the worker, with matching Claude Code,

Codex, Antigravity, generic AGENTS.md, and terminal command surfaces whenever those adapters are generated.

System Agents - Copy, Never Write

Single packages copy NONE of the canonical system-agent bodies (pm-soul, memory-curator, policy-gate, eval-qa) and must not author substitutes for them. Their functions are covered by the runtime layers declared in `$ENGINE/system-agents/folder-rules.md` (resolve `$ENGINE` as in hep-build Step 0): the deterministic always-on curator, the Memory Ticket ledger, the project soul log, the host PreToolUse hook, and the host judge engine. The package declares - via `.agentlas/mcp-policy.json`, `.agentlas/memory-map.json`, `.agentlas/memory-tickets.jsonl`, and `.agentlas/capability-eval-plan.json` - and never implements policy or judge logic.

Routing Contract — Non-Negotiable

The routing card is the same artifact in all four builders. Author or repair it with `skills/routing-card-authoring/SKILL.md`, which states what belongs in every field, and copy `templates/routing-card.example.json` as the starting shape. Two rules from that spec decide whether the card is findable at all: open-world English `workforce.communities`, `skills`, `roles`, and `knowledge` concepts plus a `summary` that names the deliverable in the requester's words carry semantic matching; the ontology snapshot is a seed graph, never an allowlist. NEVER write a `description` inside `required_inputs`, `optional_inputs`, `consumes` or `produces` — the compiler turns every string in those objects into a concept id, so one sentence becomes one slug nothing can ever match.

`package-contract.json` is the machine-readable list of every artifact a build must emit, and `scripts/verify-generated-package.sh <folder>` enforces it. A build missing a required artifact FAILS. Use the canonical paths in the contract, including `mcp-policy.json` and the evaluation artifacts; the list is mandatory.

Four artifacts carry routing and are as mandatory as `AGENTS.md`:

• `contracts/intake.schema.json` — INPUT contract. Every fact the requester must

hand over before work starts becomes a property; `required` names the ones without which the work does not begin. Direction is carried by the filename because nothing else ever marked it.

• `contracts/output.schema.json` — OUTPUT contract. What the requester ends up

holding. The brief compiler reads only this file's topology (arity and value spaces), never its titles or descriptions, so the derived routing facts cannot drift with the author's vocabulary.

• `contracts/output.example.json` — one real instance, validated against

`output.schema.json` by a JSON Schema validator at publish time. Never by a model
