description	[omh] Hermes Codebase Onboarding workflow: create a repo map, reading path, glossary, risk map, and first-task runway for unfamiliar codebases. Use when the user says: codebase-onboarding, codebase onboarding, repo onboarding, repository onboarding, codebase tour, code tour, new repo orientation, understand this repo.

Codebase Onboarding

This is a Hermes-native codebase-onboarding workflow skill.

Why This Exists

codebase-onboarding adapts ECC's code-tour and onboarding surfaces into an OMH-native first-read workflow so unfamiliar repos become navigable before implementation pressure starts.

Do Not Use When

• The user already named a concrete implementation task and acceptance criteria; use ultrawork or idea-to-deploy.
• The user needs a whole-workspace capability inventory; use workspace-audit.
• The user wants a code diff review; use code-review.

Examples

Good example:

• Prompt: codebase-onboarding 처음 보는 레포라서 구조, 주요 모듈, 테스트, 첫 작업 후보를 잡아줘.
• Expected behavior: Prepare repo_map/v1, reading_path/v1, domain_glossary/v1, risk map, and first_task_runway/v1 from observed files.
• Why: The request is repo orientation before implementation.

Bad example:

• Prompt: codebase-onboarding 파일 안 읽고 이 레포 아키텍처를 확정해줘.
• Expected behavior: Mark architecture as unobserved and inspect source evidence before making claims.
• Why: Onboarding is only useful when grounded in current repo evidence.

Completion Checklist

• The plan names goals, non-goals, assumptions, acceptance criteria, and verification shape.
• Draft recommendations, accepted decisions, and executor handoffs are separate states.
• Rejected options or unresolved tradeoffs are recorded before handoff.

Recovery Notes

• If acceptance criteria or verification are missing, route back to clarification before handoff.
• If assumptions materially affect the plan, keep them visible and avoid treating the plan as accepted.

Workflow Lane

• Current lane: Intent -> plan (oh-my-hermes, meta-router, deep-interview, context, plan, ralplan, codebase-onboarding, codegraph-refresh, +4 more) - clarify, plan, ship, or loop goals.
• If intent belongs to another lane, hand back to oh-my-hermes or name the adjacent workflow.
• Shared product, routing, compatibility, and evidence rules: omh-routing/references/skill-common-rail.md.

Use When

Use when Hermes should help an operator or coding executor understand an unfamiliar repository before planning implementation.

Strong routing signals: `codebase-onboarding`, `codebase onboarding`, `repo onboarding`, `repository onboarding`, `codebase tour`, `code tour`, `new repo orientation`, `understand this repo`, `how this repo works`, `first task runway`, `개발자 온보딩`, `레포 온보딩`, `코드베이스 온보딩`, `처음 보는 레포`, `레포 구조 설명`

Catalog Metadata

Category: planning Phase: codebase-onboarding Hermes role: planner Quality tier: onboarding-gated Reasoning demand: standard

Quality bar:

• Name the audience, depth, repo root, read-only boundary, and stop condition.
• Separate observed files and commands from inferred architecture and unknowns.
• Produce a practical reading path and first-task runway rather than a flat file tour.
• Route follow-up implementation to plan, ultrawork, verification-gate, or workspace-audit as needed.

Handoff policy:

Keep codebase orientation in Hermes as prepared local context. File reads, generated maps, and first-task recommendations need observed repo evidence; code edits and executor handoffs happen only after onboarding identifies a concrete task.

Required inputs:

• repo root or supplied source context
• target audience: operator, new contributor, maintainer, or executor
• desired depth: quick map, architecture tour, first issue, or handoff pack
• known constraints such as no network, no secrets, or read-only mode

Expected outputs:

• codebase_onboarding_plan/v1
• repo_map/v1
• reading_path/v1
• domain_glossary/v1
• risk_and_unknowns_map/v1
• first_task_runway/v1
• not-evidence boundary

Artifact expectations:

• repo_map/v1 with observed directories, entrypoints, generated surfaces, tests, docs, scripts, and runtime artifacts
• reading_path/v1 ordered from product direction to architecture, core modules, tests, and operational docs
• domain_glossary/v1 with repo-specific terms, owners, artifacts, and evidence references
• first_task_runway/v1 with low-risk starter tasks, verification commands, and handoff readiness

Safety rules:

• Do not invent architecture, ownership, maturity, or runtime behavior without observed repo evidence.
• Do not mutate files, run setup, install dependencies, or dispatch an executor from onboarding alone.
• Keep onboarding findings, inferred risks, first-task suggestions, and implementation handoffs separate.
• Never expose secrets from config or environment files; record only redacted paths and risk categories.

Runtime Evidence

Preferred harness for this skill: codebase-onboarding.

omh runtime record --skill codebase-onboarding --harness codebase-onboarding --status started

Record observed delegation results; otherwise return not_available or not_observed. Prepared OMH routing is not execution, review, CI, merge-readiness, or merge evidence.

• Treat wrapper memory/context summaries as advisory local context, not proof of opaque Hermes memory reads or changes. Preserve workflow intent and stop conditions; verify before claiming completion.

Use Hermes-native subagent/delegation features when available: native subagents -> Hermes delegation when available, otherwise sequential lanes.

Shared product, compatibility, topology, memory, harness, and execution rules: omh-routing/references/skill-common-rail.md. Load it when applicable; otherwise name an unavailable capability.
