SKILL.md

Startup Loop

Operate the Startup Loop through a single chat command surface. This skill is an operator wrapper. It does not replace the DO processes (/lp-do-fact-find, /lp-do-analysis, /lp-do-plan, /lp-do-build).

Operating Mode

ORCHESTRATE + GATE + HANDOFF

Allowed:

  • Read canonical Startup Loop docs and current business artifacts.
  • Determine current stage and gate status.
  • Hand user exact prompt files and output paths when input/research is missing.
  • Validate submitted artifact path and stage fit.
  • Enforce Business OS sync actions before stage advance.

Not allowed:

  • Silent stage skipping.
  • Advancing while required artifacts or BOS sync actions are incomplete.
  • Treating markdown mirrors of cards/ideas as source of truth.

Invocation

  • /startup-loop start --business <BIZ> --mode <dry|live> --launch-surface <pre-website|website-live> [--start-point <problem|product>]
    • --start-point is optional. Default is product. Existing runs that omit this flag are unaffected.
  • /startup-loop status --business <BIZ>
  • /startup-loop submit --business <BIZ> --stage <STAGE_ID> --artifact <path>
  • /startup-loop advance --business <BIZ>

Business resolution pre-flight: If --business is absent or the directory docs/business-os/strategy/<BIZ>/ does not exist, apply _shared/business-resolution.md before any other step.

Command Module Routing

Load the relevant module per command:

Command Module
start modules/cmd-start.md
status modules/cmd-status.md
submit modules/cmd-submit.md
advance modules/cmd-advance.md

Internal modules (called automatically — not operator-invocable):

Module Trigger
modules/assessment-intake-sync.md Called by cmd-start and cmd-advance as part of ASSESSMENT-09 Intake contract validation (GATE-ASSESSMENT-00). Writes or refreshes <BIZ>-<YYYY-MM-DD>assessment-intake-packet.user.md from ASSESSMENT-01–ASSESSMENT-08 precursors. No-op when precursors are unchanged.
modules/cmd-advance/advance-contract.md Shared advance contract: BOS sync expectations, blocked-packet requirements, operator sequence, and red flags.
modules/cmd-advance/assessment-gates.md cmd-advance submodule for ASSESSMENT gate family (GATE-A08-00, GATE-ASSESSMENT-00, GATE-ASSESSMENT-01).
modules/cmd-advance/market-product-website-gates.md cmd-advance submodule for MARKET / PRODUCT / WEBSITE gate family (GATE-BD-03, GATE-PRODUCT-02-01, GATE-WEBSITE-DO-01).
modules/cmd-advance/signals-gates.md cmd-advance submodule for SIGNALS weekly advance routing (/lp-weekly, GATE-BD-08).
modules/cmd-advance/sell-gates.md cmd-advance submodule for SELL strategy/activation gates and SELL-01 secondary dispatch.
modules/cmd-advance/s9b-gates.md cmd-advance submodule for S9B→SIGNALS advance gates. GATE-LAUNCH-SEC (Hard): blocks when security domain fails or QA report is absent/stale (>30 days). GATE-UI-SWEEP-01 (Hard): blocks when no recent business-scoped rendered UI contrast sweep artifact exists, or when artifact is stale/incomplete/has S1 blockers.
modules/cmd-advance/gap-fill-gates.md cmd-advance submodule for ongoing loop gap-fill dispatch gates (GATE-LOOP-GAP-01/02/03).

Required Output Contract

For start, status, and advance, return this exact packet:

text
run_id: SFS-<BIZ>-<YYYYMMDD>-<hhmm>
business: <BIZ>
loop_spec_version: 3.15.0
current_stage: <STAGE_ID>
current_stage_label: <label_operator_short for current_stage>
current_stage_display: <label_operator_long for current_stage>
next_stage_label: <label_operator_short for next eligible stage or null>
next_stage_display: <label_operator_long for next eligible stage or null>
status: <ready|blocked|awaiting-input|complete>
blocking_reason: <none or exact reason>
next_action: <single sentence command/action>
prompt_file: <path or none>
required_output_path: <path or none>
naming_gate: <null>  # deprecated field; retained for backwards-compat
bos_sync_actions:
  - <required sync action 1>
  - <required sync action 2>

Stage Addressing

Flag Behavior
--stage <ID> Canonical stage ID. Case-insensitive. Always primary. Legacy IDs S3 and S10 are accepted and remapped to map-canonical IDs (SIGNALS-01, SIGNALS) for compatibility.
--stage-alias <slug> Deterministic slug from stage-operator-map.json alias_index. Fail-closed on unknown.
--stage-label <text> Exact match against label_operator_short or label_operator_long. Case-sensitive. Fail-closed on near-match.

Resolver: scripts/src/startup-loop/stage-addressing.ts Canonical alias source: docs/business-os/startup-loop/_generated/stage-operator-map.json

When a stage reference cannot be resolved, return fail-closed with deterministic suggestions. Do not infer or guess stage IDs from near-matches.

Stage Model

Canonical source: docs/business-os/startup-loop/specifications/loop-spec.yaml (spec_version 3.15.0). Stage labels: docs/business-os/startup-loop/_generated/stage-operator-map.json.

Global Invariants

  • Never allow silent stage skipping.
  • Never bypass the S4 merge-and-commit boundary before WEBSITE/DO progression.
  • Canonical source of truth is always loop-spec.yaml — not markdown mirrors of cards or ideas.
  • All stage references are resolved via stage-addressing.ts — never guess stage IDs.
