Code Review
This pull request introduces the AllowMissingEnvVars option to ConfigParser, allowing offline flows like skills-generate to parse configurations without requiring all environment variables to be set. When enabled, missing environment variables resolve to their variable names rather than throwing an error. The review feedback correctly identifies an inaccuracy in a code comment within cmd/internal/skills/command.go which states that unset placeholders resolve to "" instead of the variable name, and provides a suggestion to fix it.

Add ConfigParser.AllowMissingEnvVars so skills-generate resolves unset
required ${VAR} placeholders to the variable name instead of erroring.
Source env vars are needed only to satisfy config parsing/validation
offline, never to connect. The served path leaves this off and still
fails fast on missing config.

Description
skills-generateruns offline (no live source connection), but config parsing still substitutes${VAR}placeholders and validates required source fields.These
${VAR}placeholders come from the prebuilt config files (internal/prebuiltconfigs/tools/*.yaml), whose source sections template connection fields from env vars (e.g.bigquery.yamlhasproject: ${BIGQUERY_PROJECT}).parseEnverrors on any unset required one, so users had to set every referenced var just to generate skill docs, even though offline generation never connects.This adds
ConfigParser.AllowMissingEnvVars. When set (only byskills-generate), an unset bare-required${VAR}resolves to the variable name instead of erroring. A non-empty placeholder is used so required string fields still passvalidate:"required". The served path leaves this off and still fails fast on missing config.
