From 4f395dd0ec7379c420d3035481fbba3c6a2f6533 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 6 Oct 2026 08:34:01 +0000 Subject: [PATCH 1/3] fix(model): classify compound commands for auto-run ClassifyCommand only looked at the first word, so with ai.agent.view enabled `curl ... | sh`, `ls | xargs rm -rf` or `cat a; rm -rf ~` were auto-run as "view". `shelltime q` is about to send repository-controlled text (file names, commit subjects, script names) to the model, so the classifier has to be safe against a manipulated suggestion. - Split pipelines, lists and substitutions (quote and escape aware) and return the most severe segment. - Treat interpreters and wrappers (sh, python, xargs, sudo, eval, env with a command, find -exec, ...) and multi-line scripts as "other", which never auto-runs. - Upgrade view commands that redirect output to a file, and downloads (curl -o, wget), to "edit". - Classify git, docker/podman, kubectl and systemctl by subcommand: read-only subcommands stay "view", `git reset --hard`, forced pushes, branch/stash deletion and `kubectl delete` are "delete", and exec, reboot and global git options are "other".

When ai.shareContext is enabled (the default) it now also sends a `context` object, collected concurrently within 500ms: - system: OS version, kernel, arch, CPU count, uptime, load average, root, SSH, container, multiplexer, terminal, timezone and local time (read from /proc and sysctl, no forks) - git: path in repo, branch, upstream, ahead/behind, staged, unstaged, untracked and conflicted counts, in-progress operation, remote hosts and the last 3 commit subjects; falls back to HEAD if `git status` is slow - project: types and package managers from manifest and lock files, walking up to the repo root for monorepos, plus package.json script, Makefile target and justfile recipe names - tools found on PATH, and up to 40 names from the current directory The shell is now taken from the parent process when it is a known shell, so a fish session started from a zsh login shell is reported as fish. `shelltime q --show-context "..."` prints the request without calling the AI. With ai.shareContext: false only shell, OS and query are sent.

A leading global option now classifies as "other" (never auto-run), as git already did. - ParseJustRecipes indexed fields[0] on lines made only of non-ASCII whitespace (\v, \f, NBSP), panicking inside a collector goroutine and crashing `shelltime q`. Skip such lines. - Recover panics in query context collectors so a collector bug can only drop that piece of context.
