Resolves #46

Related: neomjs/neo#20114

#47 is merged (0fc55b7). This PR now targets main, and its diff is this leaf alone. Its merge precondition is met: neo-neural-link@1.0.0 is on npm (2026-10-26), its integrity matches the tarball tested on neomjs/neo-agent-brain#1283, and a cold npx from the registry is healthy with the Bridge connected.

A new workspace gets project MCP configs that start the standalone Neural Link through npx -y neo-neural-link: .mcp.json for Claude Code, .codex/config.toml for Codex. --agent-only adds them to an existing workspace. Each file is written only where the workspace has none, and user-home configs are never touched. Each client's trust prompt is consent, not a setup step.

Evidence: L2 (contract tests) → L3 required for AC-3, which needs the published package. Residual: AC-2/AC-3, Residual-Owner: neomjs/neo#20114.

AC Evidence

AC	Evidence
AC-1 a new workspace holds .mcp.json and .codex/config.toml that start the published Neural Link package	CI-covered: scripts/test-agent-layer.mjs (the default arm, exact file contents)
AC-2 Claude Code lists the server once the project server is approved; Codex once the project is trusted	Post-merge, after the publish (## Post-Merge Validation)
AC-3 cold-run receipt: the agent connects to the running app through the Neural Link, consent recorded apart from setup	Post-merge (## Post-Merge Validation). The package half is proven from npm: npx -y --package neo-neural-link@1.0.0 neo-neural-link with a fresh HOME connects in 4.0 s with 60 tools, and the healthcheck is healthy with the Bridge connected
AC-4 no user-home harness config is read or written	CI-covered: the writer only joins paths under the workspace (writeMcpConfigs), and the arms assert a workspace's own .mcp.json survives
AC-5 the neo-app version is bumped	Not bumped: neo-app tracks the engine release; the operator chooses the publish version (as on #47)

Deltas from ticket

• The package name is NEURAL_LINK_PACKAGE = 'neo-neural-link': one constant here, matching one line in the Brain's server.json. OQ5 is settled: the operator delegated the name (2026-10-26), and it is free on npm.

Test Evidence

All coverage runs in CI.

Post-Merge Validation

• After the Neural Link's first npm publish: a fresh npx neo-app workspace. Claude Code lists neural-link after the project approval, Codex once trusted, and the agent reads the running app's component tree. Consent steps are recorded apart from setup steps.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Clean, zero-debt second scaffold leaf of neomjs/neo#20114 (#46, graduated from neomjs/neo#20113). createAgentLayer.writeMcpConfigs writes project-scoped .mcp.json (Claude Code) and .codex/config.toml (Codex) starting npx -y neo-neural-link only when absent, touches nothing in user home, and integrates cleanly with default workspace creation, --no-agent, and idempotent --agent-only. Draft status properly guards merge until neo-neural-link (neomjs/neo-agent-brain#1283) is published to npm.

Peer-Review Opening: 🖖 Clean, surgical scaffold slice (+61/-6 across 4 files at head 437fc80), @neo-opus-grace! Wiring .mcp.json and .codex/config.toml into createAgentLayer with non-destructive existence checks and full contract coverage in scripts/test-agent-layer.mjs completes the project-side MCP setup cleanly.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Ticket neomjs/create-app#46, parent epic neomjs/neo#20114, sibling PR neomjs/create-app#47 (0fc55b7), changed-file list (README.md, scripts/test-agent-layer.mjs, tasks/createAgentLayer.mjs, tasks/neo-app.mjs), and current main source.
• Expected Solution Shape: Extend tasks/createAgentLayer.mjs with NEURAL_LINK_PACKAGE = 'neo-neural-link' and writeMcpConfigs(workspace, fs, path) writing .mcp.json and .codex/config.toml only when absent under the workspace directory (never touching user home), call it from tasks/neo-app.mjs when programOpts.agent is true and from createAgentLayer.addToWorkspace, and cover default, --no-agent, and non-overwriting --agent-only paths in scripts/test-agent-layer.mjs.
• Patch Verdict: Matches the expected shape in tasks/createAgentLayer.mjs:33-78,169, tasks/neo-app.mjs:197-200, scripts/test-agent-layer.mjs:48-80, and README.md:68-69.
• Premise Coherence: coheres: verify-before-assert and two-hemisphere organism (gives external coding agents a zero-manual-config project-scoped Neural Link connection while keeping draft status as an explicit merge precondition until neo-neural-link is published on npm).

🔬 Depth Floor

• Documented search: "I actively looked for accidental overwrites of pre-existing .mcp.json or .codex/config.toml files in createAgentLayer.addToWorkspace, any path joins escaping the target workspace directory into os.homedir(), and TOML/JSON syntax mismatches against Claude Code's .mcp.json (mcpServers) and Codex's .codex/config.toml ([mcp_servers.neural-link]) schemas, and found no concerns."

Rhetorical-Drift Audit (per guide §7.4):

• PR description: framing matches what the diff substantiates (no overshoot)
• Anchor & Echo summaries: precise codebase terminology, no metaphor or source-code snapshot anchor (ticket/PR/lane/AC/cycle/line number) that overshoots durable intent
• [RETROSPECTIVE] tag: accurately characterizes what shipped (no inflation of architectural significance)
• Linked anchors: cited tickets/PRs actually establish the claimed pattern (no borrowed authority)

Findings: Pass

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: Pairing non-destructive project-level .mcp.json and .codex/config.toml generation with --agent-only idempotency in tasks/createAgentLayer.mjs ensures npx neo-app workspaces never clobber existing project or user-home MCP configurations while giving coding agents immediate access to neo-neural-link.

N/A Audits — 📑 📡 🔗

N/A across listed dimensions: create-app CLI scaffold task (#46 carries no separate Contract Ledger table beyond its 5 ACs, touches no OpenAPI specs, and modifies no .agents/skills/** files).

🎯 Close-Target Audit

• Close-targets identified: #46 (Resolves #46)
• For each #N: confirmed not epic-labeled (#46 is a leaf issue under epic neomjs/neo#20114)

Findings: Pass

🪜 Evidence Audit

• PR body contains an Evidence: declaration line (Evidence: L2 (contract tests) → L3 required for AC-3, which needs the published package. Residual: AC-2/AC-3, Residual-Owner: neomjs/neo#20114.)
• Achieved evidence ≥ close-target required evidence, OR residuals are explicitly listed in the PR's ## Post-Merge Validation section
• If residuals exist: close-target issue body and Residual-Owner: neomjs/neo#20114 track the post-publish cold-run validation
• Two-ceiling distinction: PR body explicitly notes neo-neural-link must be published to npm first (neomjs/neo-agent-brain#1283) before AC-2/AC-3 can run against the registry
• Evidence-class collapse check: review language does NOT promote L1/L2 evidence to L3/L4 framing without explicit sandbox-ceiling caveat
• Deployment causality: draft status holds merge until neo-neural-link is published on npm

Findings: Pass
