Then the model's FINANCE.md and the workspace conventions: both come back as `conventions` in the results of `layerz_get_model`, `layerz_create_model`, `layerz_build_from_blueprint`, an unfiltered `layerz_read` and `layerz_get_conventions`. They describe this workspace and this model (currency, units, signs, depth, structure, who reads it) and override the defaults below. Your own skills and instructions keep their priority on how you work. This skill describes how the Layerz tools work and in which order; it states no fact about any business.\n\n## When this applies\n\nFirst conversation with Layerz, a workspace with no model yet, \"what can Layerz do\", \"where do I start\".\n\n## Sequence\n\n1. `layerz_list_models`. Read `workspaces[]` (`has_conventions` says whether its members wrote a Context) and `models[]`.\n2. When `models` is empty, do not stop there. Offer two ways in one sentence:\n   - from a template: `layerz_list_templates`, then `layerz_create_model { template_id, timelines }` (a template's `description` is its FINANCE.md, the usage guide);\n   - from the business: ask 4 to 6 questions (what the company sells and to whom, how it makes money, stage and size, horizon, who reads the model) and wait for the answers. When the user says to go ahead, build on stated assumptions and list them in the FINANCE.md as open questions.\n   - from an existing workbook: `layerz_create_upload_url`, PUT the file, `layerz_parse_file { file_id }` (its `workbook` says what Layerz recalculates, its scenarios and data tables; `guidance` says how to proceed), then `layerz_create_model { file_id, name }`. The import runs after the answer and its report lands in the model's FINANCE.md; a `409 IMPORT_DECISION_REQUIRED` lists the decisions to ask the user (undated period headers), answered through `anchors`. See the Rebuilding a workbook reference.\n3. `layerz_get_conventions { workspace_id }` before the first write. `custom_instructions` is the workspace Context: what its members expect of a model (depth, structure, presentation, working style). Follow it; it is theirs.\n4. Build in one pass with the `business-plan` skill: `layerz_build_from_blueprint { apply_if_clean: true }`, then `layerz_read { health: true }`, fix every failing check, then `layerz_set_finance_md` and a `glyph` through the `meta` op of `layerz_patch`.\n5. End with the model's `url` and three lines: what was built, the assumptions taken, what is left to decide.\n\n## Where a preference goes\n\nWhen the user states a preference, write it where every agent and every teammate will read it, and say where it went:\n\n- about every model of this workspace (depth, structure, formats, working style): the workspace Context, `layerz_set_custom_instructions { workspace_id, content }`. The write replaces the whole text (3,000 characters at most): read the current one with `layerz_get_conventions` first and keep what is there.\n- about this model (currency, units, signs, statement structure, objective, open questions): its FINANCE.md, `layerz_set_finance_md { model_id, content, summary }`.\n- about how you work (tone, questions, deliverables): the user's own skills or instructions, not Layerz.\n\nFinance judgement (is the plan credible, what to challenge, what a lender looks at) is not in this plugin: the Layerz cookbook (github.com/layerzlabs/cookbook) has skills for that, which the user installs and adapts.\n\n## References\n\nFrom the Layerz modeling guide (version 1.1.0; the whole guide: `layerz_get_conventions { include_guide: true }` or the `modeling-guide://reference` resource):\n\n- [1.
