In plain words
What is it for?
Use it to review a plan or project idea through one question at a time, with the number of questions adjusted to the project's complexity.
Why use it?
It brings hidden assumptions, unclear requirements, and possible problems to the surface while there is still time to address them.

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

plan-interview 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 3d 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.

The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plan Interview

Conduct in-depth technical interviews about project plans to deeply understand implementation details, uncover hidden assumptions, and identify potential issues before implementation begins.

Language: Match the user's input language. Use explicitly requested language if specified.

Workflow

Step 1: Understand Input

Input: $ARGUMENTS

  • File path (contains / or ends with .md, .txt) -> Read the file, use Glob for related files
  • Text description -> Use directly as project concept

Step 2: Assess Complexity

Complexity Indicators Questions
Simple Single feature, clear scope 3-4
Medium Multiple features, some integrations 5-7
Complex System-wide, many integrations 8-10

Step 3: Conduct Interview

Use AskUserQuestion tool. Ask ONE question at a time.

For question areas, see references/interview-areas.md.

Progress Tracking: Display after each question:

[Progress: 2/6 | Covered: Architecture, API | Remaining: Security, Testing]

Guidelines:

  • Ask meaningful follow-up questions
  • Dig deeper on vague answers
  • Challenge assumptions respectfully
  • Skip non-applicable areas

Intermediate Save: Every 3-4 questions, save to .interview-progress-<timestamp>.md:

  • Questions asked and responses
  • Areas covered and remaining

Completion: Interview ends when:

  1. All relevant areas covered, OR
  2. Maximum questions (10) reached, OR
  3. User requests to end

Before ending: "I've covered [areas]. Anything else before writing the specification?"

Step 4: Write Specification

Use template from references/spec-template.md.

Output location:

  • File input -> Same directory with -spec suffix
  • Text input -> Ask user, default ./specs/<project-name>-spec.md

Cleanup: Delete .interview-progress-*.md after successful spec generation.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
