Skills and connector packaging

Connector boundary

Bridge Town’s remote Claude and OpenAI directory profiles are static product catalogs. They contain tools, schemas, annotations, and safe product-reference metadata. They do not deliver behavioral prompt templates, user-authored instructions, or a runtime skill lookup surface.

The profile contracts make this explicit:

• Claude profiles have empty resources and prompts arrays.
• OpenAI profiles have empty resources, prompts, and skills arrays until the future static importer is implemented.
• search_tools returns only ranked product tools. It never returns a skill match or a follow-up action that loads external behavior.

This boundary keeps a connector description or tool result from asking its host to fetch, render, honor, or follow dynamic instructions.

Separate packages

The 19 workflow skills listed below ship in the Bridge Town plugin for Claude Code, together with an operating-guide skill, a model-review agent, and confirmation guardrails. They are not included as resources in the remote connector. The plugin is installed, reviewed, and versioned separately from the connector, so the connector profile stays a static product catalog.

The OpenAI/ChatGPT profile does not import these files. A later OpenAI-specific implementation may publish no more than five deliberately selected, immutable skills through OpenAI’s static importer snapshot. That importer owns its manifests, resource digests, limits, and rescan process; it is not a server-side alias for the repository’s Markdown files.

The public Skills REST directory is also separate. Its user-authored records must not be copied into a connector profile or treated as host instructions.

Static reference resources

Resources remain appropriate when they are immutable product data that cannot change host behavior. Examples include the bsheet JSON schema and worked schema examples, dashboard chart-type schemas, and enum/reference tables. These resources describe data contracts; they do not contain agent workflow instructions.

Package catalog

Every package has a valid frontmatter name/category/context declaration and its related_tools names resolve against the canonical MCP tool manifest.

Package file	Skill name	Category	Status
bridge_town_gsheet_formatting.md	bridge-town-gsheet-formatting	Google Sheets	Model-output publishing is distinguished from dedicated value-writing and formatting surfaces.
bridge_town_bsheets.md	bridge-town-bsheets	BSheets	Current; uses canonical tools, schema resources, and automatic edit guidance.
bridge_town_scenario_sheets.md	bridge-town-scenario-sheets	BSheets	Current; branch/edit/run/compare workflow consumes automatic run receipts.
collaborate_on_project.md	collaborate_on_project	Collaboration	Current; workspace model templates are distinguished from skill packages.
commit_files.md	commit_files	File management	Current; atomic file-commit guidance is complete.
connect_google_sheets.md	connect_google_sheets	Data integration	Current; OAuth prerequisite and refresh path are explicit.
convert_excel_workbook.md	convert_excel_workbook	Data integration	Uses the current workbook conversion tools and package metadata.
create_cash_flow_model.md	create_cash_flow_model	Model authoring	Current; runnable model and entrypoint guidance is complete.
create_dashboard.md	create_dashboard	Dashboards	Current; chart schemas and create/share flow are explicit.
create_expense_model.md	create_expense_model	Model authoring	Current; required files and run path are complete.
create_headcount_model.md	create_headcount_model	Model authoring	Current; required assumptions and run path are complete.
create_marketplace_gmv_model.md	create_marketplace_gmv_model	Model authoring	Current; supply, demand, and take-rate assumptions are complete.
create_revenue_model.md	create_revenue_model	Model authoring	Current; drivers, outputs, and run path are complete.
create_unit_economics_model.md	create_unit_economics_model	Model authoring	Current; CAC/LTV assumptions and outputs are complete.
create_usage_based_pricing_model.md	create_usage_based_pricing_model	Model authoring	Current; usage and pricing assumptions are complete.
discover_and_query_data.md	discover_and_query_data	Data integration	Current; source discovery, freshness, and query guidance are complete.
gsheet_finance_styles.md	gsheet-finance-styles	Google Sheets	Corrected: points to the canonical formatting package name and preserves the write/format split.
run_scenario_analysis.md	run_scenario_analysis	Scenario analysis	Current; branch-based what-if workflow is complete.
scenario_analysis.md	scenario_analysis	Model authoring	Current; new-model scenario authoring is distinct from branch analysis.

This catalog does not make these files remotely discoverable. Packaging changes must update the relevant Claude plugin or future OpenAI importer snapshot and its digest evidence separately.
