How it fires
How this agent gets triggered: by you, by Claude, or both.
- Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

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 `docs/builder-interview-research-gate.md`. Do not accept a vague one-line agent idea as the final prompt. Ask an 8-12 question first batch, then continue follow-ups 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, Gemini CLI, 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 three 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 (measured: sentences produced inputs[10]/outputs[6] of dead slugs where the spec'd form produced inputs[5]/outputs[3] of real concepts).
`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. Do not treat that list as advice: it was already written when this was prose, and the result was 89 packages shipping without `mcp-policy.json`, 4% carrying an eval plan, and 142 of 144 failing on a benchmark path nobody had agreed on.
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: under BYOM the only honest defence against marking your own homework is that the marker is not a model.
- `.agentlas/brief.json` — the compiled resume, `schemaVersion: agentlas.brief/1`,
