New `VcsKnowledge` plugin (`hg`, `svn`, `bzr`, + `fossil`, `cvs`, `jj`, `git-lfs`, `glab`, `tig`, `lazygit`) — the + version-control category previously held only `git`. New `ModernCliKnowledge` + plugin (`jq`, `yq`, `fd`, `rg`/`ripgrep`, `bat`, `eza`, `delta`, `fzf`, `sd`, + `gron`, …). Existing plugins gained many entries: network inspection/transfer + (`nmap`, `ip`, `ss`, `netstat`, `tcpdump`, `mtr`, `socat`, `lftp`, `tailscale`, + `wg`, `rclone`, `mc`, …) and more cloud CLIs (`doctl`, `flyctl`, `heroku`, + `vercel`, `wrangler`, `gsutil`, `bq`, `eksctl`, …); build/test tooling (`cmake`, + `ninja`, `bazel`, `just`, `pytest`, `jest`, `tsc`, `vite`, …); package/version + managers (`bun`, `pipx`, `poetry`, `uv`, `conda`, `rustup`, `asdf`, `nvm`, `nix`, + `snap`, `flatpak`, `twine`, …); containers/orchestration (`buildah`, `skopeo`, + `oc`, `minikube`, `kind`, `kubectx`, `k9s`, …); databases (`pgcli`, `duckdb`, + `cockroach`, `mongodump`, `dropdb`/`dropuser` → `highRisk`, …); editors (`code`, + `helix`, `kak`, `man`/`info`, …); crypto/secrets (`age`, `sops`, `cosign`, + `pass`, `certbot`, macOS `security`, …); more archive/compression tools; and + process/hardware inspection (`lsof`, `vmstat`, `free`, `lscpu`, `dmesg`, …). +- **Security-critical disk/system commands** that previously classified as + unknown (empty capabilities → "safe"). A new `DiskKnowledge` plugin covers + disk-format/wipe tools (`mkfs`, `mkfs.*`, `mke2fs`, `mkswap`, `wipefs`, + `blkdiscard` → `critical`), partitioners (`fdisk`, `gdisk`, `sgdisk`, + `cfdisk`, `parted` → `highRisk`), macOS `diskutil` (erase verbs refined to + `critical`) and secure-delete tools (`srm`, `wipe`). `SystemConfigKnowledge` + gained kernel-module (`modprobe`, `insmod`, `rmmod`, `kextload`/`kextunload`), + power/run-level (`shutdown`, `reboot`, `halt`, `poweroff`, `init`, `telinit`) + and privileged-config tools (`visudo`, `nvram`, `spctl`, `csrutil` — `disable` + refined to `critical`), plus more routine config names. +- `dd` now refines `of=/dev/...` (writing directly to a block device) to + `critical` with a `systemConfiguration` capability. + +### Changed + +- **Per-subcommand/argument refinement** for high-traffic multi-mode tools. + `kubectl`/`oc` split into read (`get`/`describe`) vs write (`apply`) vs + `delete` (highRisk) vs `exec`/`cp` (executePrograms). `terraform`/`tofu`/ + `terragrunt`/`pulumi` keep `plan`/`preview` read-only while `apply` is + mediumRisk and `destroy` (or `-auto-approve`) is highRisk. `systemctl` is now + read-only for `status`/`show`/`list-*` and only attributes + `systemConfiguration` to state-changing verbs (`reboot`/`poweroff` highRisk). + `npm`/`pnpm`/`yarn`/`bun` `run`/`exec`/`dlx` attribute `executePrograms`; + `docker`/`podman` `rm`/`rmi`/`prune` attribute `deleteFilesystem`; + `aws`/`gcloud`/`az` raise risk on `rm`/`delete`/`destroy` tokens; `vault` + splits read vs write; `ansible-playbook --become` adds privilege escalation. +- `kill`/`pkill`/`killall` now flag the catastrophic forms — signalling PID 1 + (init), `-1`/`0` (every process / the process group), a match-all pattern + (`pkill .`) or `-u root` — as `highRisk`, while a normal `kill ` (incl. + `kill -1 ` SIGHUP) stays safe. +- `find -delete` is now classified by `DestructiveCommandDetector` — + `find / -delete` is `critical` (and denied), while a scoped `find . -delete` + stays a medium deletion. Recursive `chmod`/`chown`/`chgrp` on a filesystem + root or system directory (`chmod -R 777 /`) is now `highRisk`. +- `ShellExecutionDetector` now also flags **language interpreters running inline + code** — `python -c`, `node -e`/`-p`, `bun -e`, `perl -e`/`-E`, `ruby -e`, + `php -r`, `lua -e`, `osascript -e`, `Rscript -e`, `elixir -e`, `groovy -e` and + `deno eval` — as `highRisk` (matching `bash -c`), without flagging an + interpreter that merely runs a script file (`python app.py`). +- **`command -v`/`-V` lookups are no longer treated as executing their target.** + `command -v rm` (or `command -v mkfs`) resolves the name like `which`/`type` — + it now reports only `readFilesystem` instead of inheriting the target's + capabilities/risk, and `DestructiveCommandDetector` skips it (so + `command -v mkfs.ext4` is no longer a false `critical`). Actually running a + command through `command` (`command rm -rf /`) still looks through as before. + Adds a `WrapperSpec.lookupFlags` knob. +- Normalization resolves the Debian binary renames `batcat`→`bat`, + `fdfind`→`fd` and the package name `ripgrep`→`rg`. +- `DestructiveCommandDetector` now also classifies disk-format/wipe tools + (`mkfs`/`mkfs.*`/`wipefs`/…) and `dd of=/dev/...` as `critical`, looking + *through* wrapper commands (so `sudo mkfs.ext4 /dev/sda` is caught), and + treats whole-disk device nodes (`/dev/sd*`, `/dev/nvme*`, `/dev/disk*`, …) as + catastrophic targets. `CommandFamilies` gained a `diskDestructive` set and an + `isDiskDestructive` helper, and extended its `destructive` (`srm`, `wipe`, + `blkdiscard`), `downloaders` (`lftp`, `yt-dlp`, `youtube-dl`, `certutil`, + `bitsadmin`) and `privilege` (`gosu`, `run0`, `please`) sets. +- `RemoteExecDetector`'s raw-text fallback now recognises the additional + downloaders and the `pwsh`/`powershell`/`cmd` shells in `download | shell` + patterns. + ## 1.1.0 ### Tests diff --git a/lib/src/capabilities/command_knowledge_base.dart b/lib/src/capabilities/command_knowledge_base.dart index 1c0f08e..4327978 100644 --- a/lib/src/capabilities/command_knowledge_base.dart +++ b/lib/src/capabilities/command_knowledge_base.dart @@ -115,14 +115,22 @@ final class CommandKnowledgeBase { // Recurse into wrapped commands (sudo/env/xargs/...), bounded to avoid // pathological inputs. if (entry?.wrapper != null && depth < 4) { - final wrapped = _wrappedCommand(entry!.wrapper!, args); - if (wrapped != null) { - _collect( - wrapped.executable, - wrapped.arguments, - match, - depth: depth + 1, - ); + final spec = entry!.wrapper!; + if (spec.lookupFlags.isNotEmpty && args.any(spec.lookupFlags.contains)) { + // A lookup form (`command -v foo`) resolves/prints the named command + // without executing it, so it does not inherit the target's + // capabilities — it only inspects the filesystem/PATH. + match.add(CommandCapability.readFilesystem); + } else { + final wrapped = _wrappedCommand(spec, args); + if (wrapped != null) { + _collect( + wrapped.executable, + wrapped.arguments, + match, + depth: depth + 1, + ); + } } } return depth == 0 ? entry : null; diff --git a/lib/src/capabilities/knowledge/command_knowledge.dart b/lib/src/capabilities/knowledge/command_knowledge.dart index c62705f..1eb29d8 100644 --- a/lib/src/capabilities/knowledge/command_knowledge.dart +++ b/lib/src/capabilities/knowledge/command_knowledge.dart @@ -39,6 +39,10 @@ enum KnowledgeCategory { /// Container and orchestration tools (`docker`, `podman`, `kubectl`). container, + /// Infrastructure-as-code and configuration-management tools (`terraform`, + /// `ansible`, `pulumi`, `vault`, …). + infrastructure, + /// Network clients and utilities (`curl`, `ssh`, `ping`, cloud CLIs). network, @@ -250,6 +254,7 @@ final class WrapperSpec { const WrapperSpec({ this.skipLeadingFlags = true, this.skipAssignments = false, + this.lookupFlags = const {}, }); /// Whether leading `-`-prefixed option tokens are skipped before the wrapped @@ -259,6 +264,12 @@ final class WrapperSpec { /// Whether leading `NAME=VALUE` assignment tokens are skipped (as with /// `env FOO=bar cmd`). final bool skipAssignments; + + /// Flags that turn the wrapper into a *lookup* rather than an execution, so + /// the named command is resolved/printed but **not** run (e.g. `command -v + /// foo` / `command -V foo`).
