Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Descripción del creador (original en inglés)
Review coding-agent plans on demand with peer models, attributed findings, and a structured verdict.
Estos tres nunca se combinan en una sola puntuación: las opiniones, las mediciones y la popularidad son cosas distintas.

Claude plans it. GPT reviews it. You approve it.
A plausible plan can commit an agent to a migration, authentication change, payment flow, compatibility break, or deployment that is expensive to undo.
Inspectrum is an independent pre-flight check before that decision. Its first automatic integration runs when Claude Code exits plan mode: Codex (GPT) reviews the plan before the approval dialog reaches you, findings can send the plan back for revision, and you keep final approval. If the reviewer cannot run, the plan passes through with a visible warning instead of being silently reported as reviewed.
Here, independent means a reviewer distinct from the author model, invoked separately. It does not mean their errors are statistically independent. Inspectrum makes the checkpoint repeatable and its failures visible; a net reliability gain and a defensible moat are not yet proven. The post-0.2.2 strategy defines the evidence gates and keeps code review, pull-request review, and pair programming out of scope.
For an occasional second opinion, a rule can tell one agent to call another and compare the replies. That is a reasonable lightweight option.
Inspectrum is for the repeatable checkpoint. In Claude Code, the plugin runs at the plan-to-execution boundary without relying on a remembered prompt, caps revision loops, and fails open on operational errors. Other local MCP hosts can call the same review_plan contract on demand. Both paths keep findings attributed, return a common verdict shape, preserve human control, and write local evidence for successful reviews.
Recreating those guarantees with a skill means maintaining the orchestration, output validation, health checks, failure policy, and session record yourself.
Public availability as of 1 August 2026: npm 0.2.3, the GitHub release, and the repository's Claude and Codex plugins are aligned on 0.2.3. Glama is public. The MCP Registry may still show 0.2.2; it was not republished in this pass. Inspectrum was not in the public Claude Community catalog, while PulseMCP blocked the one-time recheck with HTTP 403, so no current PulseMCP listing claim is made.
The public 0.2.3 activation evidence records exact commands, timings, one useful finding, one null result, one visible fail-open case, and the limits of the measurement.
You need Node 20+, Claude Code, and Codex CLI >= 0.99.0 authenticated with a ChatGPT subscription (no API key):
claude plugin marketplace add yannmenec/inspectrum
claude plugin install inspectrum@inspectrum
That's the whole install. Next time you finish a plan in plan mode:
⏺ ExitPlanMode
⎿ inspectrum×codex: REVISE (round 1/2) # abridged — real output Majors: # adds a full-report path
⏺ ExitPlanMode ⎿ inspectrum: codex approved the plan (session 2026-07-12…). ┌ Ready to code? ──────────────── │ Here is Claude's plan… ← your normal approval dialog
No prompt to remember, no button, zero tokens spent on triggering. The gate is a deterministic hook — it fires on every plan, whether your session runs Fable, Sonnet, or Haiku. Two commands give you the automatic gate; the on-demand /inspectrum:review command needs one extra line (registering the MCP server — shown in the assisted setup below).
Prefer the agent to install and check everything for you? Paste this into Claude Code.
Set up Inspectrum's Codex plan gate. Use normal approvals only — do not
switch to Bypass Permissions or Full Access.
Steps:
node --version. If < 20, stop and tell me to install Node 20+ from https://nodejs.org first.codex --version. If it is missing or older than 0.99.0, run npm install -g @openai/codex@latest and verify again.claude plugin marketplace add yannmenec/inspectrum, then claude plugin install inspectrum@inspectrum.claude mcp add --transport stdio --scope user inspectrum -- npx -y inspectrum@latest (this powers the on-demand /inspectrum:review command).npx -y inspectrum@latest doctor and show me the output, including the resolved codex model/effort lines.codex login status.osascript -e 'tell application "Terminal" to do script "codex"' Then tell me: "A Terminal window opened with codex running. Inside that window, click 'Sign in with ChatGPT', complete the login in my browser, then close the Terminal window. Inspectrum is then ready."Do NOT use sudo, edit shell profiles, push git changes, read .env or credentials, or publish packages. Report back: Node version, codex install status, doctor verdict, and whether login was needed.

Paste this into the Codex app or CLI:
Set up Inspectrum so I can review my plans with Claude. Use normal
approvals only.

Which model reviews, at which effort? On the Codex side, precedence is:
| Setting | 1st (wins) | 2nd | 3rd |
|---|---|---|---|
| model | [reviewers.codex] model in ~/.inspectrum/config.toml | model in ~/.codex/config.toml | codex built-in default |
| reasoning effort | [reviewers.codex] effort | model_reasoning_effort
