description

Use this Skill, not a named task Skill, when that Skill or capability is the object of user-level setup, installation, migration, or configuration. An installed or runtime-discovered copy is target evidence, not a desired source. If the human has not supplied the selected capability's source, return `NEEDS_INPUT` before reading it, inventory, lookup, planning, or action; never inspect secret values. Use for "set up my agents on this machine", "migrate my AI coding setup", "新设备配置 Codex/Cursor/Claude Code", "update my global agent workflow", or reconstructing selected skills, harness guidance, plugins, MCP, hooks, permissions, runtimes, and authentication prerequisites. Setup does not imply marketplace discovery, CLI/provider installation, or full-toolbox adoption. Do not use for project-local agent workflow design, fleet policy, sessions/caches, or unrelated dotfiles.

Agent Environment

Principle expression

Primary: P12 Supporting: P14, P16, P15

Scope

Own one recurring judgment: what minimum user-level workflow source lets this person reconstruct and evolve the intended coding-agent capabilities and working agreements across tools and devices, and how can each projection be reconciled and verified without copying secrets, opaque state, or accidental machine history?

This Skill owns inventory classification, portable workflow-source formation, three-way reconciliation, migration receipts, and ordinary-entry verification. It does not own project instructions, provider accounts, secret storage, tool implementation, organization policy, or the acceptance of a personal working agreement. Use an existing dotfiles or configuration manager as the carrier when one is already trusted; do not replace it with a new framework.

Read concepts when desired source, projection, secret prerequisite, local state, or override are being conflated. Read current tool surfaces only for tools in scope, and re-check their official documentation before writing because vendor surfaces change.

Principle source

Use a host Sequence and matching interpretations when the host declares them. Otherwise use this Skill's read-only fallback in references/sequence.md. Read only P12, P14, P16, and P15.

Dispatch

Before dispatch or inspection, apply this source gate: when setup names a selected capability but supplies no desired source or source locator, return a plain final response with status NEEDS_INPUT and one scoped request for that source. This is not an interactive-question tool call. Stop without listing or reading skills, inventorying either device, consulting vendor material, or forming a conditional installation plan. Treat an installed or runtime-listed copy as target evidence, never as the missing desired source.

• With audit, read and follow commands/audit.md.
• With setup, read and follow commands/setup.md.
• With reconcile, read and follow commands/reconcile.md.
• With migrate, read and follow commands/migrate.md.
• With verify, read and follow commands/verify.md.
• With no argument, begin with a read-only audit. Do not infer authority to change user-level files from a request to inspect or recommend.

Start

Person and device(s) in scope:
Selected harness/tool and ordinary use path, if required:
Required capabilities and working agreements:
Requested setup surface and explicit exclusions:
Existing desired source or carrier, if any:
Prior source revision and receipt, if relevant:
Configuration that must remain machine-local:
Secret/authentication prerequisites, named but not read:
Target OS, shell, and trust constraints:
Human approval and rollback boundary:
Observation that would show successful reconstruction:

If the user has not authorized writes, stop after inventory and a proposed reconciliation. Never print, copy, commit, or ask a model to summarize secret values, authentication databases, session transcripts, caches, or machine identifiers.

Core method

1. Recover intended work before files. Name the recurring actions, capabilities, working agreements, and verification observations. Select only the setup surfaces needed to enable that work: a skill or capability, harness guidance/configuration, runtime tooling, authorization, or another bounded subset. These are composable surfaces, not mandatory levels. Do not infer a CLI install, provider route, or full environment from the word setup, and do not treat every file under a vendor home directory as desired state. Resolve the target harness from the request or active runtime only when a projection needs one. If the target is missing and would change the action, ask one scoped question; do not scan installed tools to guess it. Resolve a selected capability's desired source through the pre-dispatch source gate. Enter marketplace discovery only after an explicit request. For every projection, name its material ordinary-use benefit and added burden; preserve the unchanged environment when the gain is not material. Keep user scope thin: concise nearly-universal agreements, source locators, and native discovery of already-selected on-demand capabilities. A named capability is setup data, not an instruction to invoke it or install its target harness.
2. Inventory through supported surfaces. Inspect only what the selected capability can depend on. A skill setup may need source, installer, and discovery evidence; a harness setup may add instructions, plugins, MCP, hooks, or permissions; a runtime setup may add installation provenance, versions, and authentication status. Record paths and presence; redact values. For one skill, inspect only its source, the selected harness's discovery surface, and a same-name conflict there—not unrelated vendor directories. In a classify/propose-only task, the declared source locator and skill identity are sufficient unless compatibility or safety depends on its content; do not fetch or load the skill body merely to plan an installer-managed projection. Use official status or diagnostics commands when available. Treat the declared target device as the object; the active host running this Skill is not the target unless the human says so. When the target is another or hypothetical device and no target access is supplied, plan from declared facts and leave target observations unresolved.
3. Classify every item. Assign desired source, tool projection, secret prerequisite, machine-local state, local override, or unknown. Unknown and conflicting items block automatic copying; they do not become portable merely because they are readable.
4. Select the smallest carrier. Reuse an accepted dotfiles/configuration source when present. For one bounded capability, a source locator, explicit selection, and setup receipt may be sufficient. Prepare a small user-controlled profile from the profile template only when recurring setup has multiple independently changing modules or needs later reconciliation. Store workflow intent, source locators, install provenance, non-secret modules, projection mappings, exclusions, and verification—not vendor caches or an export of $HOME.
5. Plan per tool from current documentation. Read only the relevant section of tool surfaces, then verify the current official path and precedence. Prefer a supported import, installer, settings command, or structural merge over editing undocumented application stores. Choose an installation mechanism only after the desired source and selection are known. An installer's catalog or marketplace cannot supply missing setup intent. If current documentation, runtime help, or diagnostics are unavailable, name the lookup/manual action; never invent an exact command or configuration key. Treat discoverable vendor mechanics as lookup-required, not as missing human intent; ask the human only for a choice, authority boundary, or source that investigation cannot determine. Every exact command or key in a plan or receipt must carry the official page, inspected --help, or runtime diagnostic that admitted it in this activation. Words such as example, equivalent, or likely do not bypass this gate.
6. Reconcile source evolution, not files alone. For ongoing updates, compare the last applied source/projection, the target's current state, and the new approved source. Map changed workflow intent to affected tools before editing. A tool-local change is a target observation or candidate source change; it does not flow upstream without human adoption.
7. Apply without taking ownership. Back up or checkpoint each managed target; merge structured configuration by key; use clearly delimited blocks only for text projections; preserve unmanaged content byte-for-byte when the carrier promises that boundary. Do not replace a whole user configuration to make one setting match.
8. Rehydrate secrets separately. Retain only the credential's purpose, provider, required scope, preferred secure store, and status check. On the target device, use the tool's supported login or secret-manager path and let the human complete interactive authorization.
9. Verify through ordinary use paths. Check parse/discovery, then run one harmless behavior probe per selected capability. A copied file is not proof that the intended agent or runtime loaded it. Confirm an adjacent unselected surface was not changed and preserve one relevant unmanaged item as boundary evidence. Also confirm that the selected projection improved its named action without adding an unnecessary always-on instruction, runtime, updater, or duplicate source. When marketplace discovery is a live competing trigger, repeat the raw setup request through the ordinary classifier with the actual installed skill set; do not name this Skill or disclose the expected route.
10. Return a reconciliation receipt. Report applied, preserved, deferred, unsupported, and failed items; source revision; target/tool versions; rollback locations; manual authorization still required; and observations that should reopen the profile. The receipt is evidence, not a new source. Classify every mechanical action as verified or lookup-required; omit the command/key entirely for lookup-required actions.

Boundaries

• Do not make one vendor's hidden directory the cross-tool source of truth.
• Do not migrate chats, sessions, memories, caches, telemetry, indexes, UI layout, or device identifiers by default. Promote a specific item only after the user names the future decision it must support and its privacy boundary.
• Do not translate every setting across tools. Preserve common intent where a faithful projection exists; otherwise retain an explicit tool-specific commitment or unsupported result.
• Do not make full runtime installation the implicit meaning of setup. A skill-only or harness-only setup is complete when its declared capability and boundary probes pass; unselected surfaces are out of scope, not failures.
• Do not add a projection merely for cross-tool symmetry. Prefer each harness's smallest native, on-demand surface; leave an already sufficient environment unchanged rather than manufacturing setup parity.
• Do not turn user scope into an always-on control plane. A user-level setup is thin by default; move project truth and specialized behavior to the narrower project or on-demand surface that owns it.
• Do not turn setup into third-party capability discovery. Marketplace search is eligible only when the human explicitly asks to discover or compare candidates; it never fills a missing source in an otherwise selected setup.
• Do not make a generated tool configuration bidirectionally authoritative. Adopt a tool-local improvement into the workflow source explicitly, then project it outward in a later reconciliation.
• Do not bake current vendor paths or keys into universal doctrine. Re-check the linked official source during execution and record the observed version.
• Do not claim setup complete while authentication, an ordinary-entry probe, or an unresolved conflict remains hidden.
• Do not require Codex, Cursor, Claude Code, a particular OS, a dotfiles manager, or this repository after the Skill is installed.

Completion standard

An environment setup, update, or migration is ready only when its declared scope, desired source or source locator, and human owner are explicit; every in-scope item has a state classification; secrets and local state remain outside the desired source; existing target content has a rollback path; each selected capability passes an ordinary-use verification or is visibly deferred; every applied projection has a named material benefit and bounded burden; and the receipt states residual manual work and deliberate no-ops. When a portable profile is actually used, source and target drift must be distinguished, and the profile must remain updatable without copying opaque vendor state or overwriting target differences.
