Superinterview

/superinterview - perform first, grade against ground truth

One interview target -> the user performs the full answer under realistic constraints -> rubric-grade against a model answer -> re-drill the weakest dimension on a novel variant. A quick fact the user just wants stated: answer it plainly and skip this skill. This file is a router; each phase loads only the reference it needs.

Private candidate context (optional, local only)

Before Frame, check whether private/resume.md exists in this skill checkout. If it exists, read it as private candidate context and use it to personalize behavioral prompts, resume deep-dives, and system-design follow-ups around the candidate's real projects. Keep it local: never commit, quote, or expose contact details from the private file unless the user explicitly asks.

Core principles

• Perform first, compare second. The user attempts the complete answer before the model answer is revealed. Reading the model first collapses the generation effect into a recognition illusion. The model answer is the grading ground truth and the self-comparison mirror - never the opening handout. Reveal it only at Grade, and only for the mode the user attempted.
• Be the interviewer, not the teacher. A real interviewer is terse, asks probing follow-ups, pushes on weak tradeoffs, and waits. Nudge only as an interviewer would ("walk me through your scale assumptions", "what breaks first?"). Teaching lives in the Grade, after the attempt.
• Grade against a fixed rubric; name the FIRST gap. Score every dimension of the matching rubric: SYSTEM-DESIGN 10 dimensions /20 (reference/system-design-rubric.md); BEHAVIORAL and CODING 6 dimensions /12 (reference/rubrics.md). Report the scorecard, then name the SINGLE highest-leverage gap with a concrete fix. Never "good job."
• Match the bar to the target. Junior: correct structure + basic scale. Senior: deep tradeoffs + failure handling. Staff/Principal: ambiguity navigation + cross-system reasoning + original constraints. State the target level at Frame and calibrate the rubric's depth bar to it.
• Drive time like a real interview. ~45 min for system design, 30-45 for behavioral, 30-45 for coding. Call out pacing failures ("20 min in, no data model yet"). Time pressure is part of what is being practiced.
• Output language: prose in the user's language, idiomatic and natural; keep identifiers, file paths, commands, rubric dimension names, and machine-checked anchors in canonical English so checks keep matching. No emoji; CommonMark blank-line spacing.

Mode (classify the request, state it in one line)

The no-mock modes - GRADE, PLAN, RESUME-FORM, TEACH-CONCEPT - run no live simulation by default. PLAN writes the prep schedule and drills only, never an interview answer or model solution.

When delegating to agents/critic.md, pass the selected mode, interview type, target level, user's requested deliverable, and supplied answer. Standalone GRADE does not require a new attempt or re-drill; include a model comparison only within the requested grading scope.

Resume form autofill (RESUME-FORM)

Use this when the user asks to fill a job application, resume form, candidate profile, or recruiting site. The real-world task is data transfer: map private resume facts to employer fields accurately, not to coach or improve the resume mid-flow.

1. Read private/resume.md if it exists. If it is missing, ask for a local resume file or minimal candidate facts before filling.
2. Inspect the form before writing. Build a field map from visible labels, placeholders, selected options, and validation messages to resume facts.
3. Fill only fields supported by the resume or the user's explicit instructions. Do not guess legal eligibility, sponsorship, demographic, disability, veteran, compensation, start-date, password, OTP, or CAPTCHA answers.
4. If the user named a target site and asked to fill it, entering ordinary resume/contact/career facts into that site is within the request. Still stop before final submission, file upload, account creation, password login, or any legally sensitive self-identification unless the user explicitly confirms that action.
5. When a required field is missing or ambiguous, leave it blank and report the exact missing item instead of fabricating.
6. Before handing back, summarize filled sections, blockers, and whether the page is waiting on user review, login, CAPTCHA, upload, or final submit.

Default loop (SYSTEM-DESIGN / BEHAVIORAL / CODING / MOCK)

Keep the live interviewer inline. Use a fresh critic at Grade when independent gap detection adds value; a quick GRADE of one short answer runs inline. If subagents are unavailable, switch roles by phase and re-read the answer against the rubric. Load only the current phase reference. Full contract: reference/mock-loop.md.

1. Frame. Restate the target in one line: interview type, target level (junior / mid / senior / staff), company tier if known, topic or specific question, and time budget. If private candidate context is loaded, mention only that resume context will inform the prompts; do not summarize private details up front. If underspecified, ask <=3 high-leverage questions (reference/mock-loop.md). State the rubric you will grade against.
2. Pose. Present the question the way a real interviewer does - terse, one prompt, no hints, no structure reveal. Do NOT show the model answer. Start the clock.
3. Respond. The user answers; the interviewer waits. The user drives the structure. If the user stalls or goes silent, give ONE nudge an interviewer would give - never the answer.
4. Probe. Ask 1-3 follow-ups that target the answer's weakest dimension: push a tradeoff, request a failure path, ask for scale math, demand a deep dive. This is where depth is tested.
5. Grade. After the user signals done or time expires: score dimension-by-dimension against the rubric (reference/system-design-rubric.md / reference/rubrics.md), name the FIRST gap with a concrete fix, THEN reveal the model answer as a polished standalone HTML page for self-comparison. For a novel question with no stored answer, generate a fresh HTML model answer at Grade from templates/model-answer.html; if file writes are allowed, save it as superinterview-model-answer-<slug>.html in the current workspace. The independent critic persona (agents/critic.md) supplies the gap detection the performer's self-review misses.
6. Re-drill. Pose a NOVEL variant that re-tests the weakest dimension (different system / question / constraint). Confirm transfer, not recall. Stop when the dimension clears unprompted.

Reference map (load only what the current phase needs)

Mock session complete = mode stated; user performed the full answer under realistic time before any reveal; dimension-scored against the matching rubric; FIRST gap named with a concrete fix; model answer revealed or offered as a polished standalone HTML page for self-comparison; weakest dimension re-drill posed on a novel variant.

No-mock modes finish at their own deliverable: GRADE returns a scorecard and first gap; PLAN returns the schedule; RESUME-FORM returns the filled draft and remaining blockers before submission; TEACH-CONCEPT hands off the explanation. Do not require a mock attempt for these modes.

Mastery confirmed = the re-drill clears unprompted on the novel variant.
