Resolves a plugin name against the published plugin-registry index, resolves a release tag (newest, or --version pinned), downloads the release's source tarball, and copies its plugins/ directory into <CRS_ROOT>/plugins (or --plugins-dir). Existing files are never overwritten unless --force. Records the installed repository, tag, and a per-file digest for a future plugin list/upgrade to detect drift. Warns when a plugin ships Lua files, and when its rule ID range overlaps files already present in the target directory. --require-signature fails closed: no registered plugin publishes a signed release yet, so it always errors rather than silently skipping verification.

Inline comments:
In `@cmd/plugin/install/install.go`:
- Line 75: Update the installation reporting call to use the resolved target
directory from targetDir instead of the default
cmdContext.RootContext().PluginsDir() value, ensuring --plugins-dir is reflected
in the reported result.
In `@plugin/github.go`:
- Line 102: Limit the download and extraction sizes for untrusted plugin
archives: in plugin/github.go lines 102-102, replace the unrestricted io.Copy
path with a bounded copy that aborts when the compressed artifact exceeds the
configured maximum; in plugin/install.go lines 232-232, enforce both per-file
extracted-byte and aggregate extracted-byte limits while installing archives.
In `@plugin/install.go`:
- Line 64: Update the record structure around Digest to store a file-to-SHA-256
digest map rather than only the aggregate manifest digest, preserving the
per-file digest entries when records are created or serialized.
- Line 240: Update the destination checks in the installation flow around
os.Stat and the corresponding file-open path to use os.Lstat, reject any
symbolic-link destination including dangling links, and open files with
no-follow and exclusive-create semantics when Force is false. Apply the same
protection to both affected destination paths while preserving forced-install
behavior.
- Line 71: Propagate caller cancellation through the plugin installation flow:
update plugin/install.go Install to accept context.Context and pass it to
registry and GitHub operations; update cmd/plugin/install/install.go to call
plugin.Install with cmd.Context(); update plugin/registry.go ResolvePlugin and
fetchRegistry to use the supplied context; and update plugin/github.go
resolveTag plus the operation at line 85 to use that context instead of
context.Background().
- Line 203: Update the extraction logic around relPath and recordsFileName to
reject the reserved installation-record path and other tool-owned paths before
copying release files. Ensure attacker-controlled entries such as
plugins/.crs-toolchain-plugins.json cannot be extracted or influence
recordInstall, while preserving extraction of valid plugin files.
- Line 130: Update the installation flow around copyPluginFiles so plugin files
and their record update are staged and committed atomically. Ensure copy,
overlap-scan, or record-persistence failures roll back every created or replaced
file, leaving the target directory and records unchanged; preserve the existing
successful installation behavior.
- Line 231: Handle close errors for writable files instead of ignoring them: at
plugin/install.go lines 231-231 and 287-287, check the extracted and installed
file close results and return failures before success or digest reporting; at
plugin/github.go lines 100-100, check the downloaded archive close result and
propagate any error. Anchor the changes around each defer out.Close() cleanup
path.
- Line 307: Update findRuleIDOverlaps to traverse targetDir recursively with
filepath.WalkDir, comparing each normalized relative path against ownRelPaths
before reading candidate files, so nested .conf files are included in overlap
detection while preserving existing filtering and warning behavior.
- Line 100: Wrap each listed error return with operation-specific context using
error wrapping, including the relevant path or plugin identity where available:
temporary-directory creation, target-directory creation, plugin-file copying,
rule-ID overlap scanning, installation-record persistence, registry-request
creation, and archive-destination creation. Preserve the original errors through
wrapping so callers can still inspect them.
- Around line 335-356: Update recordInstall to Lstat the recordsPath before
reading or writing it, and return an error when the existing record file is a
symlink. Preserve normal handling for a missing file and regular files, ensuring
no read or write follows a pre-existing symlink.
In `@plugin/registry.go`:
- Line 123: Limit the registry response body before JSON decoding in the
registry fetch flow around json.NewDecoder, using the existing configured
maximum-size mechanism if available; otherwise add a bounded reader with an
explicit limit and reject responses exceeding it. Preserve normal decoding for
responses within the limit.
In `@README.md`:
- Around line 124-128: Update the plugin installation documentation after the
examples to explain that *.example configuration files are copied but not
activated automatically, and instruct users to remove the .example suffix so CRS
loads the resulting *-config.conf file.

Fix issues raised in code review on the plugin install command: - report the resolved --plugins-dir target instead of the default dir - reject a release entry named .crs-toolchain-plugins.json so it can't overwrite the install record - scan nested .conf files for rule ID overlaps, not just the top level - use Lstat instead of Stat when checking for install conflicts, so a dangling symlink is treated as a conflict rather than followed - bound the downloaded tarball and registry response sizes - check Close() errors on extracted/copied files instead of discarding them - refuse to read/write the install record through a symlink Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
