description	Think a vague feature idea into a buildable spec by working backwards (the idea→spec leg; drives the `devague` CLI). Start from the announcement ("pretend it shipped"), capture and classify claims, interrogate them with honesty conditions and hard questions, park open vagueness as a first-class object, and export a spec only once the frame *converges*. Use when the user says "think this through", "spec this", "work backwards", "turn this idea into a spec", "announcement frame", or "devague", or when a feature request is too vague to build yet. Once a spec exports, hand off to the sibling /spec-to-plan skill to turn it into a plan.

think — work an idea backwards into a buildable spec

The skill is named think; the product/CLI it drives is devague. (The forward leg — turning a converged spec into a plan — is the sibling /spec-to-plan skill, which drives devague plan.)

think turns a vague feature idea into a buildable spec by working backwards: you start from the announcement you'd make if it had already shipped, then build an Announcement Frame by capturing claims, pressure -testing them, parking what's still genuinely unknown, and only exporting once the frame converges.

The CLI is deterministic and move-driven — it is not a wizard. There is no fixed sequence of prompts. You (the agent) choose the next move; the CLI just tracks state and tells you what's still missing. Run devague learn for the canonical ten-stage arc and devague explain <move> for any single move.

This skill is the operator: a portable wrapper that resolves the CLI and forwards every move verbatim — including status, the read-only verb that reads the convergence gate and tells you the recommended next move.

Explore scope first when the idea touches an existing codebase. The sibling /scope skill is the optional opening leg: survey the surfaces the idea touches before framing, then seed the frame with boundary / non_goal / assumption claims that cite what was actually explored (provenance, not generic disclaimers). Small ideas skip it and start here — no wizard. Findings now land on the frame itself through the shipped devague scope move: start the frame with new first (scope entries live on it, like any other claim), then record each explored surface with `devague scope "<surface>" --finding "<text>" [--seeds <claim-id> ...]` — --seeds links the finding to claim ids it went on to seed, and an unknown seed id is refused with a hint. Read every recorded entry back with `scope --list [--json]`. (From the sharper end-to-end method spec, devague#53, task t3.)

How to run

The entry point is scripts/think.sh. Invoke it from the repository you are speccing (frames persist under .devague/ in the current directory):

bash .claude/skills/think/scripts/think.sh <move> [args...]
bash .claude/skills/think/scripts/think.sh status

It resolves the CLI portably — an installed devague on PATH (the normal case), falling back to uv run devague when you are inside the devague checkout. If neither resolves it prints an install hint (uv tool install devague). Every move — including status — is forwarded verbatim, so you can equally call the CLI directly (devague <move> …) when it is installed; the wrapper exists only for portable resolution.

Moves

Move	What it does
new "<announcement>" [--title "<short>"]	Start a frame from the announcement (the first move). Seeds an auto-confirmed announcement claim. Always pass --title (see Export hygiene).
capture --kind <kind> "<text>" [--instruction "<text>"]	Record + classify a claim. --origin llm lands it as proposed. --instruction attaches verbatim working guidance (how to verify/implement the claim) at creation time.
interrogate <id> --honesty "…"	Attach an honesty condition (what must be true). Also --hard-question, --risk, --contradicts, --blocking. --instruction "<text>" adds/updates a claim's or honesty condition's instruction — <id> may be a claim (c*) or, with --instruction alone, an honesty condition (h*).
confirm <id> [<id>…] / reject <id> [<id>…]	Resolve one or more claims (c*) / honesty conditions (h*) in one transactional call. User-only decision. Also confirm --from-review <file> to apply an edited review artifact.
review	List every proposed (unconfirmed) claim + honesty condition with ids and their instructions (--json too); writes a non-authoritative artifact to .devague/reviews/<slug>.md. Un-gated; never mutates.
scope "<surface>" --finding "<text>" [--seeds <claim-id> ...] / scope --list	Record (or list) a pre-frame exploration finding as first-class state (see the scope pointer above).
question "<text>"	Record / list / --resolve a pending user decision as durable working state in .devague/questions/<slug>.md.
park "<text>" --kind <kind>	Move uncertainty into first-class open vagueness instead of forcing an answer.
converge	Evaluate the gate; list remaining gaps.
export	Write the buildable spec to docs/specs/ — only after converge passes.
status	Read-only: where the frame stands + the recommended next move (--json too).
show / list	Render a frame / list frames (--json for raw state).
learn / explain <move>	Teach the method / explain one move.

Claim kinds: announcement, audience, after_state, before_state, why_it_matters, boundary, success_signal, open_question, non_goal, requirement, assumption, decision. Vagueness kinds: unknown_nonblocking, unknown_blocking, out_of_scope, follow_up.

These are exactly the kinds the shipped CLI enforces (CLAIM_KINDS / VAGUENESS_KINDS in devague/frame.py) — the skill documents the surface as built, so every command here passes the CLI's choices= validation. requirement is spec-affecting (needs a confirmed honesty condition); non_goal / decision are descriptive; an unconfirmed assumption is a convergence warning, not a blocker. The formal entity model, the (state × origin) vocabulary, and the per-move input/output/transition/error contract are documented in docs/spec-contract.md (issue #5); for the authoritative live shape of any move, run it with --json (or devague learn --json / devague explain <move>).

Instructions — verbatim guidance, never fabricated

Claims and honesty conditions may carry an optional instruction: verbatim text on how to verify or implement the item — write it yourself, don't invent filler to satisfy the gate. Two ways to set it:

• capture --kind <kind> "<text>" --instruction "<text>" — at creation.
• interrogate <c*|h*> --instruction "<text>" — add or change one on an existing claim or honesty condition (this is the one case where interrogate accepts an h* id directly, since the instruction targets whichever item you name).

Re-confirm rule. Changing the instruction on an already-confirmed claim or honesty condition flips its status back to proposed — the instruction is part of what the user confirmed, so a change to it must go back through the user. interrogate prints a diagnostic note (stderr) when this happens; re-run confirm <id>.

Gate warnings, not blockers. converge emits two deterministic, warning-only structural-sharpness signals — neither holds back ready_for_spec:

• a confirmed spec-affecting claim (announcement, audience, after_state, before_state, why_it_matters, boundary, success_signal, requirement) with no instruction;
• a confirmed success_signal claim (or claims) where none contains a measurable token — a numeral, %, or a comparator (</>/≤/≥).

Both are pure predicates over frame state, never LLM judgment on prose — see devague/convergence.py's module docstring for the exact rules (S1/S2). A frame can converge and export with these warnings still showing; they nudge toward a sharper, more directly actionable spec.

status — the next-move verb

status is a first-class, read-only CLI verb (devague status, internalised from this wrapper in 0.11.0 — issue #30). It composes list + converge and prints where the current frame stands, the remaining gaps, and the recommended next move; it never mutates state (the drafting↔converged transition stays in converge). It reports ready_for_spec, lists the blockers and warnings, and shows required_next_moves[0] as the recommended move. Pass --json for the same fields as a structured payload ({frame, total, ready_for_spec, blockers, warnings, parked_items, required_next_moves}).

frame: my-feature    (1 frame total)
convergence: NOT passed — 2 gap(s):
  - missing a 'boundary' / non-goal claim
  - claim c2 has no confirmed honesty condition

recommended next move (first gap):
  devague capture --kind boundary "<text>"

Run it whenever you're unsure what to do next.

Export hygiene — keep the artifacts lint-clean

The exported spec-md must pass the repo's markdown lint. Two gotchas found by dogfooding (devague#53), both cheap to avoid up front and expensive after — there is no retitle/edit move yet, so fixing them later means hand-editing state JSON and re-exporting:

• Always pass --title "<short title>" to new. The title becomes the H1 of every exported artifact (the plan inherits it too). The default is the full announcement — long, and if it ends with a period the H1 fails MD026 (trailing punctuation). Keep the title short, no trailing period.
• Backtick angle-bracket tokens. A placeholder like --seeds <claim-id> in claim or honesty-condition text renders as inline HTML (MD033) unless wrapped in backticks. Write `--seeds <claim-id>`, not the bare form.
• Lint before committing: markdownlint-cli2 "docs/specs/<file>.md".

Pending decisions — the question loop

When a genuine design decision surfaces mid-frame, don't guess and don't stall:

1. question "<the decision to make>" — records it as durable working state.
2. Put it to the user (with concrete options where possible).
3. question --resolve <qid> --decision "<what the user chose>".
4. capture --kind decision "<the choice>" — a user-origin capture auto-confirms, making the decision a first-class frame claim.

This keeps every user decision traceable from question → resolution → claim.

Hard rules (do not violate)

These are the point of the method — convergence must mean something.

• LLM proposals stay proposed. A claim captured with --origin llm, and any honesty condition you (the agent) propose, lands as proposed. Never confirm your own proposal. Confirmation is a user-only decision — surface the proposal and let the user confirm or reject it. Proposed content must not silently become an authoritative requirement.
• Honesty conditions route through the user. Propose them freely with interrogate --honesty; the user owns whether they hold.
• Converge, don't vibe. export is gated on converge passing. Never claim the frame is ready on a hunch — run converge (or status) and resolve every listed gap. The gate requires confirmed announcement / audience / after_state, a before_state or why_it_matters, a boundary, a success_signal, a confirmed honesty condition on every spec-affecting claim, and no unresolved blocking vagueness or hard question.
• Park real unknowns; don't paper over them. If something is genuinely unknown, park it (blocking or non-blocking) rather than fabricating an answer. Blocking vagueness holds back convergence — by design.

Output contract

Results go to stdout, diagnostics and errors to stderr — a strict split you can rely on when parsing. Pass --json to any move for a structured payload on the same stream. Exit code 0 on success, non-zero on user error (with a hint: line). Frames live under .devague/ in the current directory.

Worked example

A short end-to-end session (the kind you'd run to spec a feature like devague#5):

d() { bash .claude/skills/think/scripts/think.sh "$@"; }

d new "Devague ships a documented spec contract" --title "documented spec contract"

# Optional scope stage: record what you explored before capturing claims
d scope "devague/frame.py" --finding "the claim model devague#5 extends lives here"

d capture --kind audience "devague + the assisting LLM" \
    --instruction "check docs/spec-contract.md names devague + the LLM as readers"
d capture --kind after_state "a vague idea becomes a buildable, pressure-tested spec"
d capture --kind why_it_matters "specs converge on evidence, not vibes"
d capture --kind boundary "not a full PRD generator; no fixed wizard"
d capture --kind success_signal "a frame exports only after the gate passes"

# Pressure-test a claim, then let the USER confirm the condition:
d interrogate c1 --honesty "the contract round-trips: save -> load -> identical frame"
# ...user reviews and runs: d confirm h1

# Attach a working instruction to the now-confirmed honesty condition — this
# flips h1 back to 'proposed' (the re-confirm rule), so the user re-confirms:
d interrogate h1 --instruction "run tests/test_contract.py::test_contract_round_trips"
# ...user reviews and runs: d confirm h1

# Park a genuine unknown instead of guessing:
d park "exact JSON schema versioning policy" --kind unknown_nonblocking

d status        # what's left + the next move (warnings show with a ⚠ marker)
d converge      # gate; resolve any listed gaps (warnings never block export)
d export        # writes docs/specs/<slug>.md once converged

The exported spec-md is a buildable artifact.

After export — commit, then hand off

Once export writes the spec and the user has reviewed it, close the idea→spec leg cleanly before moving on:

1. Commit the spec. Commit the exported docs/specs/<slug>.md (along with the .devague/<slug>.json frame state and any review artifact under docs/reviews/) so the converged frame is durable in history, not just on disk. Use a focused message, e.g. git commit -m "spec: <slug> (devague /think)". The frame and the spec are the evidence trail for every confirmed claim — keep them together. (Per the repo's standing convention this normally becomes a branch + PR via the cicd skill; commit-only is fine when the user asks for it.)
2. Hand off to /spec-to-plan. The forward leg is the sibling skill: devague plan new --frame <slug> seeds a plan from the converged frame and works it forward into a buildable plan (it can equally feed superpowers:writing-plans or a normal implementation PR).

Don't pause for a "what next?" menu after a reviewed export — the standing flow is commit, then /spec-to-plan.

Provenance

This is a first-party skill — its origin is agentculture/devague, where the devague agent maintains it alongside the tool it operates (dogfooding). It is the inverse of the other skills under .claude/skills/, which devague vendors from guildmaster. guildmaster pulls this skill from devague and broadcasts it to the rest of the AgentCulture mesh. The cite, don't import policy still holds: downstream repos copy it, they don't symlink or depend on it. See docs/skill-sources.md.
