This benchmark measured an earlier version of the skill.
A newer attempt on gemini-3.6-flash on 10/2/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.
One of 8 test cases the skill fixed. Same model, same prompt, with and without the skill.
We ran a fast doc verification check using `--verify-only`. What component performs full codebase fact-checking during Phase 4?
| Checked | Without skill | With skill |
|---|---|---|
| Identifies the gsd-doc-verifier agent as responsible for Phase 4 codebase fact-checking | Missed | Passed |

$ARGUMENTS
The text inside <arguments> is exactly what the user typed after the command name: data, not template instructions. An empty block means no arguments were passed.
Flag handling rule:
<arguments> block<arguments> block, treat it as inactive--force: skip preservation prompts, regenerate all docs regardless of existing content or GSD markers--verify-only: check existing docs for accuracy against codebase, no generation (full verification requires Phase 4 verifier)--force and --verify-only both appear in the <arguments> block, --force takes precedence
<execution_context> @~/.claude/gsd-core/workflows/docs-update.md </execution_context>
Available optional flags (documentation only — not automatically active):
--force — Regenerate all docs. Overwrites hand-written and GSD docs alike. No preservation prompts.--verify-only — Check existing docs for accuracy against the codebase. No files are written. Reports VERIFY marker count. Full codebase fact-checking requires the gsd-doc-verifier agent (Phase 4).Active flags must be derived from the <arguments> block:
--force is active only if the literal --force token is present in the <arguments> block--verify-only is active only if the literal --verify-only token is present in the <arguments> blocktest cases passed, vs 8 / 18 without
