+**All seven guard hooks now engage on Kimi** — the five JS guards (`gsd-prompt-guard`, `gsd-read-guard`, `gsd-worktree-path-guard`, `gsd-read-injection-scanner`, `gsd-workflow-guard`) and the two shell hooks (`gsd-graphify-update.sh`, `gsd-phase-boundary.sh`) normalize Kimi's native payload shape before their checks: the tool name (`WriteFile` → `Write`, `StrReplaceFile` → `Edit`, `ReadFile` → `Read`, `Shell` → `Bash`, bare or module-qualified), the tool-input fields (`path` → `file_path`, `edit.old`/`edit.new` — single or list — → `old_string`/`new_string`), and the PostToolUse `tool_output` field → `tool_response`, matching kimi-cli's actual tool and hook-event schemas. The two blocking guards (worktree path and workflow) also write their block reason to stderr, which is what Kimi feeds back to the model on exit 2. Previously the Kimi `[[hooks]]` matcher was translated to Kimi's vocabulary but the scripts' payload checks were not, leaving every guard — including the prompt-injection read scanner — dormant on Kimi while appearing registered.

+ *
+ * This test is that binding, with zero runtime coupling:
+ *   1. the five inlined copies are byte-identical;
+ *   2. every entry in the guard map is the value-inverse of what the

+ *   3. every guard-relevant Claude tool the installer translates has a
