think

A structured method for turning an unclear feature idea into a buildable specification. It works backwards from the announcement you would make when the feature is finished, then records claims, questions, and unresolved details.

In plain words
What is it for?
It helps define feature claims, test whether they are honest and precise, record open questions, and export a specification for planning.
Why use it?
It prevents a vague idea from becoming code before its meaning and success conditions are clear. Unknowns remain visible instead of being silently guessed.

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

think 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 yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/think.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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.

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>" Start a frame from the announcement (the first move). Seeds an auto-confirmed announcement claim.
capture --kind <kind> "<text>" Record + classify a claim. --origin llm lands it as proposed.
interrogate <id> --honesty "…" Attach an honesty condition (what must be true). Also --hard-question, --risk, --contradicts, --blocking.
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 (--json too); writes a non-authoritative artifact to .devague/reviews/<slug>.md. Un-gated; never mutates.
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.

What ships with it

1 file 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.
