failed to read docs file: %w
Error message
failed to read docs file: %w
What it means
Returned by generateRemoteServerDocs when os.ReadFile(docsPath) fails, where docsPath is docs/remote-server.md (or the configured path). The generator reads the file to splice generated toolset tables between AUTOMATED markers; a missing or unreadable file aborts with this wrapped error.

Solutions
- Run the command from the repository root
- Confirm docs/remote-server.md exists (restore from git if deleted: git checkout -- docs/remote-server.md)
- Fix read permissions if applicable
Defensive patterns
Strategy: try-catch
Validate before calling
if _, err := os.Stat("docs/remote-server.md"); err != nil {
log.Fatalf("docs/remote-server.md missing — run generate-docs from the repo root")
} Try / catch
if err := generateRemoteServerDocs(docsPath); err != nil {
if os.IsNotExist(errors.Unwrap(err)) {
log.Fatalf("%s not found; restore it (git checkout -- docs/remote-server.md) or fix cwd", docsPath)
}
return err
} Prevention
- Run docs codegen from the repo root
- Restore deleted docs files from git before regenerating
- Keep docs/ intact in CI sparse checkouts
When it happens
Trigger: Running generate-docs outside the repo root so docs/remote-server.md does not resolve; the file was deleted/renamed during docs restructure; permission denial; custom path flag pointing nowhere.
Common situations: Subdirectory invocations of the codegen command; forks predating the file's introduction; CI sparse checkouts lacking docs/.
