Introduces a command analysis layer that categorizes shell commands, assesses risk, detects patterns, and emits metadata (category, risk level, duration hint, UX flags) before execution. Risky commands are blocked pending confirmation. Downstream UI can use the analysis to collapse verbose output and render silent successes cleanly.

Heads-up: analysis.requires_confirmation currently hard-blocks execution, but ShellArgs doesn't include any confirm/ack flag. If the intention is “ask user then re-run”, we probably need an explicit arg (default false) or a structured “needs_confirmation” error that carries analysis so the caller can display details and retry.

This flags carriage returns inside single quotes as risky (the condition only checks !in_double_quote). Probably want to treat \r like \n and ignore it in both quote modes.

There was a problem hiding this comment.
Potential bypass: base_command is derived from the first command word, so wrappers like sudo rm -rf … / env rm -rf … get categorized as sudo/env (likely Other) and won't trigger destructive confirmation. Might be worth skipping common wrapper commands (+ their flags) to recover the underlying command for analysis.

- Around line 31-46: DESTRUCTIVE_COMMANDS currently misses "rmdir" so rmdir is
classified as SILENT and skips confirmation; update the DESTRUCTIVE_COMMANDS
LazyLock initialization to include "rmdir" in the HashSet and also remove
"rmdir" from the SILENT_COMMANDS HashSet to avoid conflicting classification;
modify the static DESTRUCTIVE_COMMANDS and SILENT_COMMANDS definitions (refer to
symbols DESTRUCTIVE_COMMANDS and SILENT_COMMANDS in categorizer.rs) accordingly
so rmdir is treated as CommandCategory::Destructive.
- Around line 166-223: segment_semantics incorrectly assumes the subcommand is
words.get(1) and misses cases where wrappers (e.g., "env") or command-global
options (e.g., "-C", "--context") appear; add a helper (e.g.,
normalize_command_words) that takes the output of command_words(&segment.words)
and strips leading wrapper executables ("env", etc.), environment assignments,
and any leading global-style options (short/long flags and known global flags
like -C/--context) until the real subcommand token is reached; then replace the
current subcommand derivation (words.get(1).map(String::as_str)) with one based
on the normalized list and use that normalized list for checks in the "git",
"docker", "chmod" branches (and any flag helpers like
recursive_flag_present/force_flag_present/long_flag_present as needed).
In `@src/tools/shell.rs`:
- Around line 241-253: The analyzer is blocking "risky" commands with no way to
proceed; add a confirmation pathway by adding a confirm: bool field to ShellArgs
(or equivalent caller payload) and update the check in the function that calls
self.analyzer.analyze(&args.command, &working_dir) to only return the ShellError
when requires_confirmation is true AND args.confirm is false; if args.confirm is
true, allow execution to continue (or set a clear pending state), and ensure any
user-facing messages reflect that confirmation was used (use ShellError only for
unconfirmed attempts).

Special-case device sinks in the outside-workspace guard; treat unresolved home/env expansions in write positions as confirmation-worthy.
resolve_candidate_path() rejects ~ and $-prefixed paths, but accepts absolute paths like /dev/null. This causes benign redirects such as 2>/dev/null to be flagged as dangerous off-workspace writes and require confirmation. Meanwhile, real off-workspace writes using ~/backup.txt or $HOME/backup.txt are silently ignored because they don't resolve. The guard should whitelist safe device sinks (/dev/null, /dev/stdout, /dev/stderr) and instead treat unresolved expansions in write/redirect positions as confirmation-worthy rather than ignoring them.

Add rmdir to DESTRUCTIVE_COMMANDS.
rmdir currently classifies as CommandCategory::Silent because it only appears in SILENT_COMMANDS, not DESTRUCTIVE_COMMANDS. This causes it to bypass the confirmation gate for destructive operations despite permanently removing filesystem state. The fix is straightforward:

Handle command-global options and wrapper executables in subcommand matching.
The matcher assumes words[1] always contains the subcommand, but common patterns bypass detection:
env FOO=1 rm -rf target→ base="env", subcommand="FOO=1" (no confirmation despite destructive operation)git -C repo reset --hard→ base="git", subcommand="-C" (fails to match "reset", no confirmation)docker --context prod compose pull→ base="docker", subcommand="--context" (fails to match "compose")
The command_words() function correctly skips environment variable assignments but does not skip command-global options (e.g., -C, --context), causing subcommand matching to fail and destructive commands to bypass the confirmation gate. A helper function to normalize arguments by skipping leading command-global options before extracting the actual subcommand would close this gap.

segment_semantics incorrectly assumes the subcommand is words.get(1) and misses
cases where wrappers (e.g., "env") or command-global options (e.g., "-C",
"--context") appear; add a helper (e.g., normalize_command_words) that takes the
output of command_words(&segment.words) and strips leading wrapper executables
("env", etc.), environment assignments, and any leading global-style options
(short/long flags and known global flags like -C/--context) until the real
subcommand token is reached; then replace the current subcommand derivation
(words.get(1).map(String::as_str)) with one based on the normalized list and use
that normalized list for checks in the "git", "docker", "chmod" branches (and
any flag helpers like
recursive_flag_present/force_flag_present/long_flag_present as needed).

Hard-blocked commands have no recovery pathway despite commit message promising "pending confirmation."
The PR description states "Risky commands are blocked pending confirmation," but ShellArgs contains no confirmation flag, and the tool returns ShellError immediately with no mechanism to re-execute after approval. The LLM cannot proceed even if the user intends to run the flagged command.
Either add a confirm: bool parameter to allow bypassing the check on confirmed calls, or clarify that this is an intentional hard block and update the commit message accordingly.
