| description | PROCEDURE — migrate one legacy monolithic agent to a lean core plus routed skills. Trigger: an existing agent has measured size, embedded-configuration, duplication, aggressive-language, or multi-responsibility debt. Composes agent validation and requested skill optimization. |

nw-ab-migrate-monolith (PROCEDURE)
Kind: PROCEDURE | One job: migrate one existing agent monolith | One trigger: a legacy agent has measured size, embedded-configuration, duplication, aggressive-language, or multi-responsibility debt.
Deterministic workflow
At execution start create these as TaskCreate items and run in order.
- Baseline — Measure the agent's lines, words, bytes, responsibilities, monolith debt, and existing behavioral projections. Stop: baseline is red, the target is not an agent, or a textual pin cannot be preserved.
- Extract configuration — Move semantic configuration into frontmatter while preserving
name, model, tools, maxTurns, skills, and public behavior. Stop: a field cannot be represented without behavior change.
- Map — Reuse existing skills first. Map each original rule to one owner: lean agent core, one existing skill, or one extracted skill. Define disjoint, exhaustive triggers for extracted skills. Stop: an owner overlaps, a trigger gaps/overlaps, or public fan-out is missing.
- Simplify — Preserve the agent name, public contract, tool surface, model, and
maxTurns; retain only routing and global invariants in the core. Remove duplication and route distinct-trigger knowledge/procedures. Safety by construction first (frontmatter tool surface, typed grammar); hooks last resort with a recorded reason (GDP-0). Prefer remove, relax, route, or construct over a new check. Stop: preservation would change behavior or require added ceremony.
- De-escalate language — Replace aggressive language with direct calm language; retain
MUST only for skill-loading instructions. Stop: a required textual pin cannot be preserved.
- Optimize referenced skills — For each referenced skill selected for optimization, invoke
nw-ab-optimize-skill. Continue agent migration when it returns NOT_ELIGIBLE. Stop: a preservation risk, or a worsened resident cost without an explicit decision.
- Validate once — Batch the planned edits, run existing agent validation once through
nw-ab-validate-spec, and execute the existing behavioral projections. Do not create validators or tests. Stop: validation or a projection is red.
- Handoff — Report ownership map, trigger partition, before/after measurements, executed projections, independent-review-needed, and residual
INDETERMINATE. Stop: any required fact remains unmeasured.
Composition
| Kind | Skill | Use |
|---|
| PROCEDURE | nw-ab-validate-spec | Step 7, agent validation only |
| PROCEDURE | nw-ab-optimize-skill | Step 6, for a referenced skill selected for optimization |
| KNOWLEDGE | nw-ab-house-style | Steps 2, 4, and 5; preserve lean core and literal protections |
Boundaries
- Input is one existing agent; skill optimization remains the composed procedure's job.
nw-ab-validate-spec validates the agent result only.- Existing behavioral projections are evidence, never permission to change behavior.
- No public command, agent, or artifact is created by migration.
