Supergoal skill

About

One objective -> smallest correct change -> verified against ground truth. If invoked, run this skill's contract instead of downgrading to an inline shortcut. SKILL.md is the router; reference/ carries procedure. Unless explicitly invoked, pure brainstorming and user-driven step-by-step work use normal direct collaboration.

Standing rules (read first, every mode). Before classifying the mode, read .supergoal/rules/RULES.md if present. Honor it across phases as top-priority preference, but rules never weaken safety gates. Create/edit it only when the user explicitly asks (reference/rules.md). Check only the repo root (.supergoal/rules/RULES.md); do not tree-search for it, and skip the check entirely in an ephemeral single-task workspace (see role-loop fast path).

Core principles

• Ground truth beats proxy: re-run REAL tests, re-read request/docs, and do not optimize to self-grading.
• Exact proof beats review; implementation is delegated to a builder subagent.
• Smallest correct change; match surrounding code. Scope-minimalism governs code surface area, not UI quality: polished user-facing UI is baseline correctness.
• GREENFIELD / DEBUG / LEGACY code changes use Before/After Eval before Build: prove before, target after, and delta with trusted commands (reference/delivery-gate.md).
• Ask only when genuinely ambiguous; resolve code-answerable questions by reading the code.
• Docs language: for persistent repo docs (docs/**, run vaults, .domain-agent/**, ADR/spec/changelog), match the target repo's dominant prose language; mixed/none -> the user's language. Keep identifiers, paths, commands, and machine-checked anchors in canonical English so checks keep matching.
• DEBUG done-bar: a green reported-repro is NOT done. Before commit, print three literal lines and satisfy them - GATE.owner= the invariant-owning frame (for a raised exception: the frame that RAISES it via the traceback, not where it surfaces; for recursion: inside the enumerated cycle), GATE.alt_repro= a structurally different second repro now passing, GATE.conformance= raw-literal returns reachable through the patched path (and its symmetric sibling methods) converted to the module's canonical forms (S.One over 1). Full rules: role-loop "DEBUG hidden-contract gate".
• Hard stops: a destructive or irreversible step (drop data, force-push, external publish) needs explicit consent; if the real tests cannot pass, report it - never fake a pass.

Run isolation (GREENFIELD / DEBUG / LEGACY that edits code)

After mode detection, resolve the source/base branch and target/integration branch (repo policy, else ask). Verify both refs before mutating files, then create a run worktree from the source/base branch. Do all code work there. Do not mutate the original checkout. Commit or merge only into the verified target/integration branch after verification and user acceptance. Commit is hard-gated by the Commit gate (reference/delivery-gate.md, backstop templates/commit-gate.sh): non-green means fix/ask, never commit on assumption. Full contract: reference/role-loop.md.

Mode (classify, state it in one line)

Signal in the objective	Mode	Route
build / make / ship a new app/tool	GREENFIELD	default loop; broad/foggy builds first use a wayfinder/ Frontier Map inside the run vault, then deliver one selected frontier ticket
fix / broken / failing / crash / why does	DEBUG	default loop; observe live symptom, then failing-test repro (reference/debugging.md, driver persona agents/debugger.md); web: reference/qa.md, reference/agent-browser.md
add / integrate / refactor existing code	LEGACY	default loop; map first (agents/explore.md, reference/domain-context.md); optional DB evidence (reference/db-access.md); existing API: capture its exact behavior first as a preserve-baseline; shared code/state changes: characterization baseline (reference/qa.md)
spec / requirements first / break down / tickets / roadmap / big vague effort / frontier / what should we do first	WAYFINDER	map the destination, optional ticket-depth requirements, ticket graph, blockers, and next frontier; no product code by default (reference/wayfinder.md)
prototype / spike / try variants / prove approach before build	PROTOTYPE	throwaway proof that answers one question, then delete/quarantine or route to delivery (reference/prototype.md)
explain / teach / how does X work (no code)	TEACH	stateful teach/<topic>/ workspace (reference/teach.md); use an Archify diagram by default for structure/flow; lessons must pass node templates/teach-lesson-gate.mjs
learn / onboard / map this codebase (persist a wiki)	LEARN-DOMAIN	Survey -> Map -> Ground -> Onboard a .domain-agent/ wiki (reference/learn-domain.md; gate learn-grounding-gate.mjs)
QA / verify / 검증만 / compare data (no code)	QA-ONLY	Impact Matrix QA (reference/qa-only.md; gate templates/qa-only-gate.sh)
review / audit this code/diff/PR (no fixes)	REVIEW-ONLY	reference/review-only.md
improve the architecture / find refactoring opportunities / 구조 개선 / draw · diagram · 그려 (arch·flow·sequence·state)	ARCHITECTURE	draw-only ask: render self-contained HTML via reference/archify.md, deliver the .html, stop. Else friction survey -> candidates -> grill the pick -> route to LEGACY/WAYFINDER (reference/arch.md)
test harness/skill effectiveness / with vs without / does the skill help / measure skill lift	HARNESS-EVAL	reference/harness-eval.md
turn repeated work into a reusable skill	SKILL-MINE	reference/skill-mine.md

The no-code/utility/planning modes - QA-ONLY, REVIEW-ONLY, ARCHITECTURE, WAYFINDER, PROTOTYPE, TEACH, LEARN-DOMAIN, HARNESS-EVAL, SKILL-MINE - write no product code by default and confirm before installing anything. PROTOTYPE may write throwaway sandbox code; it cannot ship until routed back through delivery.

UI/UX overlay (any mode shipping user-facing UI). Load reference/ui-ux.md at Frame; apply the Expressive/polished baseline by default (reference/taste-skill-v2.md is the authority for ALL user-facing UI), through Build and Verify. GREENFIELD frontend: always; LEGACY: only new UI (else reuse the existing design system); non-visual work (lib, API, backend, CLI): skip.

Board overlay (optional). If the live dashboard is enabled, the conductor calls sg-emit at each phase transition; it observes only, never gates (reference/observability.md).

Default loop (GREENFIELD / DEBUG / LEGACY) - five gates, fresh context per gate

Load and follow reference/role-loop.md; it is the sole detailed authority for run setup, vault lifecycle, role inputs/outputs, retries, verification, and finalization. Invoking supergoal for these modes is explicit authorization to use its fresh-context subagents; ask again only for normal safety or permission gates. Red-green evidence is required, plus DB evidence when persisted data is load-bearing.

Mandatory core: Frame -> Plan approval -> Build -> Exact Verify/QA -> Finalize. Use one builder + one auditor verifier per iteration; browser/CLI proof adds one evidence-only qa-tester before the auditor. Only a named, recorded escalation trigger permits the conditional plan attack. Frame writes GOAL.md first and freezes a self-sufficient PLAN.md; Build starts only after approval and runs in a separate fresh-context builder from that plan; qa-tester captures the promised browser/CLI evidence, then a fresh adversarial verifier (qa-auditor) reruns REAL tests, audits the promised E2E/live/API/browser proof, and owns the final verdict, GOAL ticks, and R-LOOP. Finalize requires every criterion green, the completion marker, user acceptance, and the commit gate. Exact verification outranks review.

Roles -> personas: builder/improver=agents/executor.md, evidence-only browser/CLI tester= agents/qa-tester.md, final verifier for every default-loop path=agents/qa-auditor.md, escalation reviewer=agents/code-reviewer.md, security=agents/security-reviewer.md (others in agents/<role>.md).
