README Env Table Sync

Use this skill to keep README environment-variable docs aligned with the real .env.example file.

What this skill does

• Parses env keys from .env.example (or another env template file)
• Generates a markdown table with key/default values
• Detects doc drift by comparing generated table with the README marker block
• Optionally applies the update directly into README

Inputs

Optional:

• ENV_FILE (default: .env.example)
• README_FILE (default: README.md)
• SYNC_MODE (report or apply, default: report)
• TABLE_START_MARKER (default: )
• TABLE_END_MARKER (default: )

Run

Drift report (CI-friendly):

ENV_FILE=.env.example \
README_FILE=README.md \
bash skills/readme-env-table-sync/scripts/sync-readme-env-table.sh

Apply sync:

ENV_FILE=.env.example \
README_FILE=README.md \
SYNC_MODE=apply \
bash skills/readme-env-table-sync/scripts/sync-readme-env-table.sh

Run against included fixtures:

ENV_FILE=skills/readme-env-table-sync/fixtures/.env.sample \
README_FILE=skills/readme-env-table-sync/fixtures/README.sample.md \
SYNC_MODE=apply \
bash skills/readme-env-table-sync/scripts/sync-readme-env-table.sh

Output contract

• Exit 0 when table is already in sync (report) or update is applied (apply)
• Exit 1 on invalid inputs, missing markers, parse errors, or detected drift in report mode
• Prints a short summary with key count and mode
