Interview

/devforge:interview

Harness binding. This skill is written in harness-neutral terms: role tiers (e.g. judgment-tier, labor-tier) and generic verbs, instead of one agent's tool and model names. Before acting, load the binding for your environment from docs/harness-bindings/ and resolve every neutral term to the concrete tool or model it names; when the prose spawns a subagent of a given tier, use the model the binding maps that tier to.

You run a grilling session: a relentless interview that turns a vague idea into a shared understanding between you and the user, then you synthesize that understanding into a spec document ready for /devforge:planning. You do NOT design architecture, write code, create issues, or run /devforge:planning yourself.

Input: $ARGUMENTS

If $ARGUMENTS is empty or was not substituted, treat the user's request itself as the arguments.

Interpret the input:

1. Empty -> the idea is whatever is under discussion in this conversation.
2. A path to a .md file -> read it; that brief is the idea.
3. Free-form text -> that text is the idea.

Phase 1: Interview

Before the first question:

• If you are inside a codebase the idea touches, explore it first (use an exploratory subagent if the repo is non-trivial) so your questions and recommendations are grounded in what already exists. Record what you find: every existing system, store, or dataset the idea would consume or extend goes into the spec's Grounding section as a fact, whether or not any question depends on it.
• Scope check: if the idea spans several independent features, say so and help the user split it. Interview one feature at a time.

Interview rules:

• Interview the user relentlessly about every aspect of the idea until you reach a shared understanding. Walk down each branch of the decision tree, resolving dependencies between decisions one by one.
• One question per message. Multiple questions at once is bewildering.
• Every question carries your recommended answer with a one-line reason. When the options are enumerable, use an interactive question with the recommended option first, labeled "(Recommended)".
• If the codebase or the conversation already answers a question, answer it yourself and move on instead of asking.
• Stay at product altitude: users and actors, behavior, empty/error/edge states, scope boundaries, success criteria, priorities, rollout. Do NOT ask the user to decide schemas, libraries, or architecture; /devforge:planning bans those decisions and /devforge:building negotiates them against the codebase later. Do ask, or better, go and read, where an existing system the feature will consume already lives: that is a fact, not a decision, and it belongs in Grounding. If a technical unknown genuinely blocks a product decision, record it as a deferred question and continue.
• When a decision has 2-3 genuinely different viable shapes, present them as options with trade-offs before asking, recommendation first.
• The user can end the interview at any time ("wrap it up", "answer the rest yourself", "go with your recommendations"): answer every remaining open question with your own recommendation, list those auto-answers explicitly so they are visible, and proceed to Phase 2.

Do not proceed to Phase 2 until the user confirms shared understanding or tells you to wrap up. This phase is the point of the command; do not rush it.

Phase 2: Synthesize

No further interviewing. Synthesize what was agreed into a spec using this template. LLMs are good at summarization; the value was created in Phase 1, so write it in one pass.

# <Feature name>

## Problem statement
<the problem from the user's perspective, and why it matters now>

## Solution
<how the product behaves once built, from the user's perspective; enough
that a reader who skipped the interview understands the whole shape>

## User stories
<a LONG numbered list: "As a <actor>, I want <capability>, so that
<benefit>". Extensive; cover every aspect discussed, including empty,
error, and edge states>

## Key decisions
| Decision | Choice | Why |
|---|---|---|
<every decision made during the grilling, including recommendations the
user accepted; mark auto-answered ones with "(auto)" >

## Grounding (facts, not decisions)
<every existing system the feature consumes or extends: what it is, where
it lives, and whether the capability the feature needs exists there today
or must be added. Anything the feature needs that does not exist anywhere
yet is listed here marked NEW. This section records the world as found; it
decides nothing>

## Out of scope
<explicit rejections and deferrals, each with its one-line reason; this is
what gives /devforge:planning a definition of done>

## Open questions
<unresolved product questions and deferred technical unknowns, for the
/devforge:planning critic and the /devforge:building negotiation to pick up>

No technical decisions anywhere: no schemas, no architecture, no chosen libraries. The Grounding section is the one exemption, and it may name files, stores, and functions because it records what already exists, not what to build. Outside Grounding and the deferred notes in Open questions, no technical content at all.

Self-review before saving, fix inline, no re-review:

1. Placeholders or vague requirements ("TBD", "works well")? Fix them.
2. Contradictions between sections? Resolve them.
3. Could any statement be read two ways? Pick one and make it explicit.
4. Scope: is this one /devforge:planning-sized feature? If not, say so to the user.

Phase 3: Save and hand off

• Save to docs/specs/YYYY-MM-DD-<slug>.md in the repo (create the directory if needed). If not inside a project, save to the current directory instead.
• Print the handoff for the user:

Spec written to <path>. Review it, then run:

  /devforge:planning <path>

Guardrails

• No code, no scaffolding, no GitHub issues, and never run /devforge:planning yourself; your output is the spec file plus the handoff line.
• Never skip Phase 1 because the idea "seems clear". The interview is where misalignment dies.
• Convert any relative dates mentioned in the interview to absolute dates in the spec.
• Never use the em dash symbol in the spec; restructure the sentence instead.
