DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Reference / Feature flags

tengu_dir_sync_overlay_start

A Claude Code feature flag, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

What it is

Cloud checkouts could fast-forward from a downloaded git bundle, but no caller enables it.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.239.

Presence across releases

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Gate readings

No release here has a gate table behind it for this flag. Most published releases have none at all: the readings exist only for versions the pipeline captured flag state on.

Changelog entries naming it

  1. v2.1.242Directory-sync overlay always applies when one exists

    The directory-sync overlay always applies now; the internal flag that could skip it is gone.

    gate cited by this entry

  2. v2.1.239Directory sync can fast-forward a cloud checkout from a git bundle

    Cloud checkouts could fast-forward from a downloaded git bundle, but no caller enables it.

Documentation pages

None of Anthropic's documentation pages this site has a copy of carries this name.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the feature flag does. All feature flags.
