…ects as literal filenames extract_filepaths() answers "what file paths did this command touch" for reading commands (cat/head/tail/etc.) and grep without a real LLM round trip, by splitting the command on whitespace and keeping every token that doesn't start with '-'. That has no notion of shell redirection, so `tail -5 <path> 2>/dev/null` produced filepaths ["<path>", "2>/dev/null"] -- the redirect got treated as a second literal file, surfacing downstream as a "file not found: .../2>/dev/null" error that looked like a missing-file problem rather than the real quoting/redirect issue. Adds is_shell_operator_token (catches fused forms like `2>/dev/null`, `>>`, `|`, `&&`, `;`) and is_bare_redirect_operator (catches space-separated forms like `cmd > out.txt`, where the *next* token is a target, not something read) and applies both filters in the reading-command and grep branches.
📝 WalkthroughWalkthroughThe change adds shell-operator detection to reading and grep filepath extraction. Redirection operators and their targets are excluded, while actual input paths remain included. Tests cover stderr redirects, stdout redirects, and grep redirects. ChangesFilepath extraction

- Around line 259-262: Update is_shell_operator_token and the surrounding
command-token parsing to recognize shell operators embedded within an argument,
such as src/main.rs>out.txt, before filepath classification. Ensure redirects
attached to preceding arguments are tokenized or otherwise handled as operators,
and add coverage for both cat src/main.rs>out.txt and grep pattern
src/main.rs>out.txt.
- Around line 305-310: Update the token-scanning loops in shortcircuit filepath
extraction to terminate when encountering command separators |, ||, &&, ;, or &,
while retaining existing bare-redirect handling before continuing. Add
regression tests covering separators followed by command tokens, including the
cat/&& and grep/| examples, and verify later command arguments are not extracted
as filepaths.

Handle redirects attached to preceding arguments. command.split_whitespace() keeps src/main.rs>out.txt as one token. Because is_shell_operator_token checks only the first non-digit character, the parser reports the combined token as a filepath. Tokenize shell operators before filepath classification, or use a shell-aware tokenizer. Add cases for cat src/main.rs>out.txt and grep pattern src/main.rs>out.txt.

Stop filepath extraction at command separators. In both loops, later command tokens become filepaths. For example, cat src/main.rs && echo done includes echo and done, and grep pattern src/main.rs | sort includes sort. Stop scanning at |, ||, &&, ;, and &, while preserving redirect handling. Add regression tests for both cases.

Summary
extract_filepaths()(used by flare-proxy's shortcircuit mock to answer "what file paths did this command touch" without a real LLM round trip) split commands on whitespace with no notion of shell redirection, sotail -5 <path> 2>/dev/nulltreated2>/dev/nullas a second literal filepath.is_shell_operator_token(fused forms like2>/dev/null) andis_bare_redirect_operator(space-separated forms likecmd > out.txt, dropping the following target token too) and applies both in the reading-command and grep branches.This is the actual fix for the original vent report (item #13) that surfaced as
tail -5 <path> 2>/dev/nullfailing with a misleading "file not found" error -- produced autonomously via the now-fixed supervisor dispatch pipeline (#392-#395), reviewed and shipped by me.Test plan
