Claude Code PostToolUse hook tool_response JSON fields Bash tool stdout stderr exit code
💡 Result:
In Claude Code, the PostToolUse hook triggers after a tool call completes [1][2]. The schema for the tool_response field within the hook's JSON payload is specific to each tool [3][4]. While official documentation notes this variation, it does not explicitly define the schema for every tool [3]. For the Bash tool, empirical analysis and community documentation have identified the following tool_response JSON structure [3]: { "stdout": "...", "stderr": "...", "interrupted": false, "isImage": false } Key details regarding the Bash tool output: - Standard output (stdout) and standard error (stderr) are captured and returned in the tool_response [3]. - Note that the Bash tool itself often combines stdout and stderr into a single output stream when presenting results to Claude, though the hook may receive them separately [5][6]. - The interrupted field indicates if the process was terminated prematurely, and isImage denotes if the output contains image data [3]. - The Bash tool does not inherently provide an explicit exit_code field within this specific tool_response JSON object [3]. Evaluation of command success is typically inferred by the model from the content of the stdout/stderr fields or the presence of error signals [5]. Note that the Bash tool does not have set -o pipefail enabled by default, which can sometimes lead to silent pipeline failures [7]. For developers implementing hooks, the PostToolUse event provides context including session_id, tool_name, tool_input, and tool_response [4][8]. While hooks can observe these fields, they cannot natively rewrite the tool_response object after the tool has executed [8]. Decisions within the hook (e.g., "block" or "continue") are managed via a separate decision object that does not modify the underlying tool result [4][8].

site:code.claude.com/docs hooks PostToolUse tool_response Bash interrupted stdout stderr
💡 Result:
The PostToolUse hook is an event in agent frameworks (such as Claude Code) that fires automatically after a tool call (including Bash commands) succeeds [1][2]. Its behavior regarding stdout and stderr depends on how the hook process handles its output and exit codes: 1. Standard Behavior (Exit Code 0): - If the hook process exits with code 0, its stdout is treated as plain text or ignored by the agent's core loop, and its stderr is written only to the debug log, not the agent's transcript [1][3]. - This keeps the agent's context clean while allowing developers to record side effects or logs [2][4]. 2. Surfacing Information (Exit Code 2): - To surface a warning or specific message to the agent from a PostToolUse hook, the hook process can exit with code 2 [1][3]. - This action forces the agent to display the stderr content, even though the tool execution itself has already completed [1][3]. 3. Non-Blocking Errors: - If a hook encounters an error (e.g., non-zero exit code other than 2) or produces unexpected output, it is generally treated as a non-blocking error [1][3]. - The transcript will show a hook error notice along with the first line of stderr, prefixed with "Failed with non-blocking status code:," while the agent proceeds with its task [1][3]. 4. Advanced Control: - For more structured interactions, hooks can output JSON containing an additionalContext field [5][6]. This appends information to the tool result within the agent's context window, rather than just logging it [5][7]. - If a hook needs to change the result the agent sees, it can return an updatedToolOutput field in its output [6][7]. In the context of Bash tool use, this allows you to log command execution (e.g., by piping to a file or using a command like echo... >&2 to send logs to the debug stream) without cluttering the agent's reasoning process [2][4].

site:docs.anthropic.com Claude Code Bash tool interrupted stdout stderr tool_response
💡 Result:
When a Bash tool command is interrupted in Claude Code, the behavior depends on whether the interruption is triggered by a user action (such as Ctrl+C) or programmatically via the Agent SDK [1][2]. When you trigger an interruption: - Running commands: Claude Code terminates the process tree associated with the command [3][4]. - Transcript and state: The interrupted tool call is recorded, and leftover temporary files (such as those in /tmp/claude-*-cwd) are cleaned up [5]. - SDK behavior: If using the Agent SDK, calling interrupt sends a stop signal to the task [1][6]. The interrupted task remains in the message stream and its result message will have a terminal_reason (e.g., "aborted_tools") [1]. You must drain these messages using client.receive_response before sending new queries, otherwise the SDK may still process the interrupted task's state [1]. - General CLI: Pressing Ctrl+C in the CLI attempts to cancel the current operation [2]. If the process is unresponsive, you may need to restart the session [2]. Regarding stdout, stderr, and tool_response: - Tool results are generally marked as failed if the command is interrupted [3]. - If you are building custom hooks, stdout and stderr are handled differently based on exit codes; however, for standard Bash tool execution, the focus is on terminal cleanup and ensuring Claude is notified that the command did not complete successfully [7][8][3]. - Claude Code ensures that SIGTERM signals (when closing the program) also trigger the termination of the Bash command's process tree before exiting [4]. For developers, if a command hangs or does not finish, it is recommended to implement timeouts that force an interrupt and session restart to prevent the session from blocking indefinitely [3].

Treat interrupted Bash commands as failed verification.
The parser already reads stdout and stderr. Claude Code does not provide a Bash exit_code field, but it does report interruption. If interrupted is true and output is empty, verification_passed records the command as passed. Handle interrupted: true as failure.

The runtime-state read-modify-write is now load-bearing but is neither atomic nor synchronized.
post_tool_use calls load_runtime, mutates, then save_runtime. pre_tool_use performs the same sequence on the same file. Claude Code can run these hooks concurrently. Two outcomes follow:
- A concurrent
pre_tool_usesave overwrites the freshly writtenlast_verification. The nextitem doneis then denied even though tests passed. save_runtimewrites the whole file withfs::write. An interrupted write truncates all session state, not just the new field.
Before this PR the race only cost a nudge. It now blocks a completion action, so it is worth hardening.
Write to a temp file in the same directory and rename it over the target. Re-read the state immediately before the merge, or take a lock file around the load-mutate-save sequence.

PR #581's review (comment on item #169) found 2 critical bugs and 3 moderate issues in the combined verification-before-completion / finishing-a-development-branch gate. This fixes all five: 1. is_verification_command did a blunt substring match, so a command that merely mentioned a marker (grep -rn "cargo test" src/, echo "remember to run npm test") was recorded as real passing evidence. Now splits into shell statements, strips quoted substrings, and skips non-executing first words (echo/printf/grep/rg/...) before checking for a marker. 2. Recorded verification evidence was never invalidated when a mutating tool ran afterward, so cargo test (pass) -> edit -> item done could sail through on stale evidence. post_tool_use now clears a session's last_verification whenever a MUTATING_TOOLS call succeeds. 3. shows_finishing_branch_menu fired purely off the request action, never checking whether item done/check_merge actually took effect (done:true / promoted:true in the response). A no-op done or a check_merge whose PR isn't merged yet no longer shows the menu. 4. Dropped "status" from the exit-code field-name fallback list -- generic enough to collide with an unrelated field on some tool shapes (e.g. an HTTP status code). 5. Scoped the PostToolUse hook's matcher to the Bash-family/item/ mutating-tool union instead of firing unmatched on every tool call. Split the PostToolUse-hook logic out of hook.rs into a new hook_completion_gate module (hook.rs now re-exports post_tool_use) to stay under the repo's 1500-line LOC gate. Also reverted an unrelated, non-compiling uncommitted diff to src/cli/work.rs that was sitting in this worktree from an unrelated, apparently crashed session (dead duplicate-PR-check and workflow-store smoke-test code, never wired up anywhere) -- unblocks the build, not part of this item's scope.

Existing installs keep the previous unscoped PostToolUse entry.
add_hook_entry returns early when any entry already contains the hook post-tool-use marker. An install wired by an earlier build has that entry with no matcher, so the new scoping never applies on upgrade. The PostToolUseFailure block directly above solves the same problem by removing the old entry first. Apply the same pattern here.

Some(&post_tool_use_matcher),This makes wire_claude_code rewrite the entry on every run, so wire_claude_code_post_tool_use_is_idempotent still passes on content equality, but the added flag becomes true every time. Gate the removal on the entry lacking a matcher field if you want to keep the "already wired" skip path.

Claude Code hooks matcher regex tool name exact match official documentation
💡 Result:
In Claude Code, the matcher field does not have a separate tool name for regex; rather, the evaluation logic is determined by the characters contained within the matcher string itself [1][2]. According to the official documentation [1][3]: 1. Exact Match: If the matcher string contains only letters, digits, underscores (_), hyphens (-), spaces, commas (,), and the pipe symbol (|), it is treated as an exact string match (or a list of exact strings) [1][2]. 2. Regex Match: If the matcher string contains any character other than those listed above, it is evaluated as a JavaScript regular expression [1][2]. When using regular expressions, the match is unanchored by default (using JavaScript's RegExp.prototype.test). To perform a whole-string match, you must explicitly anchor the pattern using ^ and $ (e.g., ^Edit$) [1][2]. Additionally, for tool-specific logic, the separate if field—which uses permission rule syntax—can be used for more granular control when combined with tool names and arguments [1][4].

Record verification evidence from gateway-routed ctx_shell calls.
Lean-ctx calls use mcp__flare__tool, with the shell command nested in tool_input.args. Add mcp__flare__tool to the exact matcher and parse the nested command/cmd/script fields for server=leanctx, tool=ctx_shell. Otherwise, ctx_shell verification does not reach record_verification, and item done can be denied.

In `@src/init.rs` around lines 303 - 307, Update the post_tool_use matching and
parsing around post_tool_use_matcher to recognize mcp__flare__tool calls,
extract nested command/cmd/script values from tool_input.args when
server=leanctx and tool=ctx_shell, and pass the resulting shell command through
record_verification so item done retains its existing verification behavior.

PR #581's review (comment on item #169) found 2 critical bugs and 3 moderate issues in the combined verification-before-completion / finishing-a-development-branch gate. This fixes all five: 1. is_verification_command did a blunt substring match, so a command that merely mentioned a marker (grep -rn "cargo test" src/, echo "remember to run npm test") was recorded as real passing evidence. Now splits into shell statements, strips quoted substrings, and skips non-executing first words (echo/printf/grep/rg/...) before checking for a marker. 2. Recorded verification evidence was never invalidated when a mutating tool ran afterward, so cargo test (pass) -> edit -> item done could sail through on stale evidence. post_tool_use now clears a session's last_verification whenever a MUTATING_TOOLS call succeeds. 3. shows_finishing_branch_menu fired purely off the request action, never checking whether item done/check_merge actually took effect (done:true / promoted:true in the response). A no-op done or a check_merge whose PR isn't merged yet no longer shows the menu. 4. Dropped "status" from the exit-code field-name fallback list -- generic enough to collide with an unrelated field on some tool shapes (e.g. an HTTP status code). 5. Scoped the PostToolUse hook's matcher to the Bash-family/item/ mutating-tool union instead of firing unmatched on every tool call. Split the PostToolUse-hook logic out of hook.rs into a new hook_completion_gate module (hook.rs now re-exports post_tool_use) to stay under the repo's 1500-line LOC gate. Also reverted an unrelated, non-compiling uncommitted diff to src/cli/work.rs that was sitting in this worktree from an unrelated, apparently crashed session (dead duplicate-PR-check and workflow-store smoke-test code, never wired up anywhere) -- unblocks the build, not part of this item's scope.
