description: "Instructions for the upstream workflow: Fail-closed evidence and planning contracts for self-hosting decisions — a validated catalogue with digest, capability coverage evaluation, inventory import and export, upstream source auditing, recommendation carrying its own evidence, deployment profiles and states, install plans and TCO scenarios. Use when a self-hosting or subscription decision must be justified by evidence rather than asserted. A recommendation fails closed when coverage or provenance is missing. Not for auditing code structure — use the code_* detectors; not for the token cost of a project — use context-profiler or cost-estimator."

# subscription-saver — evidence, not assertion

## Package scope and prerequisites

This catalog ships instructions, not the executable runtime. Python modules, scripts, local services and optional tools named below must be installed separately from the upstream project. Check their availability before running commands; if they are missing, explain the prerequisite instead of claiming execution or results. The host agent may use model tokens while following these instructions.

## Purpose

Produces a plan whose every step is traceable: what capability is required,
what the catalogue covers, what the source audit found, what the deployment
profile assumes, and what the resulting cost range is. Missing evidence blocks
the recommendation instead of defaulting to a favourable answer.

    from skills.subscription_saver import (
        catalog_digest, load_catalog, validate_catalog,
        evaluate_coverage, audit_source, recommend, ...
    )

## When NOT to use

- You want static code analysis — use the code_* detectors.
- You want a project token cost — use context_profiler.
