prep

prep is a command for coding agents from noamseg/interview-coach-skill. It costs 0 tokens per session (8,816 once invoked), scanned A, original, MIT.

A command that prepares an interview brief from a job description and candidate information. It examines the role, interview format, company culture, and likely evaluation criteria.

In plain words
What is it for?
Use it to prepare for job interviews, assess fit against a role, understand how the interview may be run, and organize research about interviewers when profile links are provided.
Why use it?
It brings scattered interview preparation into one structured assessment. It helps identify which skills and experiences are most relevant to the role.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

prep scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Required Inputs

  • Company
  • Role title/seniority
  • Job description

Optional Inputs

  • Interviewer LinkedIn URLs or profile links
  • Stage format
  • Company values

Logic

  1. Identify interview format (see format taxonomy below). If the identified format is a presentation round, note: present provides dedicated content preparation coaching for presentation rounds. After this prep brief, recommend present for content structuring if the candidate hasn't already run it.
  2. If interviewer profile links provided, research interviewer profiles and extract intelligence (see Interviewer Intelligence section below). If only names provided, ask for LinkedIn URLs.
  3. Parse the JD for competencies (see JD Parsing Guide below). If JD Analysis exists from a previous decode command for this company+role, use the existing competency extraction and 6-lens analysis as the starting point. Verify it's still current (JD unchanged), then skip to Step 4. If the JD has changed since decode, re-parse and note changes.
  4. Identify company interviewing culture (see company archetype intelligence below).
  5. Infer top evaluation criteria (adjusted for format + culture).
  6. Map candidate strengths and risks — incorporate interviewer-specific adjustments if intel available. 6.5. Role-Fit Assessment — With the JD parsed and candidate profile available, run the full 5-dimension fit assessment from the Role-Fit Assessment Module (references/cross-cutting.md). See Step 6.5 below.
  7. Check storybank status and health. If the candidate hasn't built a storybank yet (no coaching_state.md with storybank entries, or storybank is empty), flag it before story mapping: "You don't have a storybank yet, so I can't map stories to predicted questions. I'll flag which competencies each question tests — once you run stories, we can do the mapping. Want to build your storybank now, or continue with the rest of the prep?" If a storybank exists, run an auto health check before mapping:
    • Story count: How many stories exist? Target: 8-12. Flag if < 6.
    • Strength distribution: How many at 4+? Target: at least 60%. Flag if majority are 3 or below.
    • Earned secret coverage: How many stories have real earned secrets vs. placeholders? Flag if < 50% have extracted earned secrets.
    • Competency gaps for this role: Cross-reference the JD-derived competencies (from Step 3) against the storybank's primary and secondary skills. Flag any critical competency with no story or only weak stories.
    • Overuse risk: Flag stories with Use Count 3+ in the current job search.
    • Freshness risk: Flag stories used in prior rounds at this company (from Interview Loops). Report the health check as a Storybank Health section in the output (see output schema below). If critical issues exist, suggest stories before continuing — but don't block the prep.
  8. Generate likely questions and story mapping. Use references/story-mapping-engine.md for the full portfolio optimization protocol. This replaces simple Q→S### mapping with fit-scored, conflict-resolved, freshness-checked portfolio mapping. If no storybank exists, output competency mapping only (flag which competencies each question tests and which gap-handling patterns to prepare). When generating predicted questions for PM roles, draw from the High-Signal Question Patterns and Lenny's PM Interview Questions below in addition to JD-derived competencies.
  9. Generate non-generic interviewer questions.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
