Summary

  • block bare packages, floating tags, wildcards, and unversioned npm aliases before install or manifest edits
  • keep local, URL, Git, workspace, and NuGet Central Package Management inputs outside registry-version checks
  • preserve auto-record safety, including failed-install payloads, and resolve npm aliases against their real registry targets
  • add regression coverage across every supported manager and manifest ecosystem
  • address the bypass reported in the Reddit feedback: https://www.reddit.com/r/coolgithubprojects/comments/1waoigu/comment/p8k0kly/

Type

  • fix (bug fix)
  • feat (new feature)
  • refactor / chore (no behavior change)
  • docs

Checklist

  • Conventional Commit title (fix:)
  • bash tests/run.sh passes locally (28/28)
  • New ecosystem? Not applicable
  • Docs touched because user-facing behavior changed

Verification

  • bash tests/run.sh
  • Bash syntax checks for changed shell files
  • focused ShellCheck for changed shell files
  • both bundled skill validators
  • git diff --check

Summary by CodeRabbit

  • New Features

    • Detects unpinned and floating dependency versions across supported package managers and manifest formats.
    • Provides package-specific guidance to retry blocked operations with an explicit verified version.
    • Recognizes npm aliases and preserves their target package and version information.
    • Documents local registry-cache storage and deletion options.
  • Bug Fixes

    • Prevents unversioned registry installs and manifest dependencies from bypassing version checks.

📝 Walkthrough

Walkthrough

The change adds a shared sentinel for unpinned registry dependencies. Parsers emit it across supported ecosystems. Hooks block unpinned entries, skip non-registry sources, and provide exact-version retry guidance. Tests cover parsing, enforcement, aliases, options, and source handling.

Changes

Unpinned dependency enforcement

Layer / File(s) Summary
Parser sentinel and source classification
scripts/lib/parse-install-cmd.sh, scripts/lib/parse-manifest.sh
Parsers emit __version_sentinel_unpinned__ for bare or floating registry dependencies. They skip paths, URLs, Git sources, links, workspaces, and similar non-registry targets.
Blocking and recording behavior
scripts/detect-install-cmd.sh, scripts/detect-manifest-edit.sh, scripts/auto-record.sh, scripts/check-versions.sh
Hooks block sentinel entries. Auto-recording and registry lookups skip them. Explicit success=false tool responses remain failures.
Parser and hook validation
tests/*, tests/fixtures/gate-invariant-commands.txt
Tests cover package-manager commands, manifest formats, aliases, floating versions, options, quoted inputs, duplicate entries, and non-registry sources.
Retry and ecosystem guidance
.agents/skills/version-sentinel/SKILL.md, .github/copilot-instructions.md, AGENTS.md, GEMINI.md, README.md, skills/version-sentinel/SKILL.md, PRIVACY.md
Documentation requires exact verified versions, describes source exclusions and NuGet Central Package Management, and documents local registry-cache retention and deletion.

Merge Risk: 🟠 High · up to 4f98e

Resolver ranges and dynamic shell expansions can bypass the exact-version enforcement this PR introduces. The npm-alias retry guidance can also change dependency names, so these issues should be corrected before merge.

Inline comments:
In `@scripts/lib/parse-install-cmd.sh`:
- Around line 54-57: Update the version-selector normalization logic around the
raw selector checks so any selector containing a wildcard, including partial
forms such as 1.*, emits VS_UNPINNED_VERSION instead of the literal selector.
Apply the same handling to the npm, Pip, Poetry, and Cargo paths, and add
parser, hook, and auto-record regression coverage for wildcard inputs.
- Around line 28-37: The install-command parser must not silently accept
unresolved shell-word concatenation such as npm install lo"d"ash. Update
_strip_install_token_quotes and its surrounding parsing flow to either correctly
combine quoted and unquoted fragments into the complete word or reject
unresolved quote-containing tokens and return the blocking/error result instead
of succeeding with no package; add regression coverage under tests/ for each
supported package manager.

In `@scripts/lib/parse-manifest.sh`:
- Around line 29-33: Update scripts/lib/parse-manifest.sh at lines 29-33, 89-94,
and 162-163: classify npm selectors by allowing only exact versions after
stripping prefixes, sending partial wildcards and multi-part ranges to
VS_UNPINNED_VERSION; replace the Python-style equality wildcard check with a
containment check for the requirements parser; and use '*' in ver in both the
string and dict branches of the Cargo parser so wildcard selectors map to the
sentinel.

Fail closed on dynamic shell expansions in package arguments.

The parser preserves but does not evaluate $(), backticks, or $VAR. It emits no record for npm install "$(printf lodash)", so the hook exits successfully before the shell installs the unpinned package. Emit VS_PARSE_AMBIGUOUS_ECOSYSTEM for these arguments and add parser and hook tests.

Preserve npm aliases in retry commands.

If the blocked input is compat@npm:lodash@latest, retry with npm install compat@npm:lodash@<exact-version>. Retrying with npm install lodash@<exact-version> changes the installed package name and can break imports from compat. Add this alias-specific example beside the generic example.

Classify all non-exact resolver selectors as unpinned.

The npm, pip, Poetry, and Cargo parsers still return several range selectors as ordinary versions. These values bypass the unpinned guard, can be auto-recorded, and later satisfy sidecar_find_fresh through exact string matching.

Emit VS_UNPINNED_VERSION for every non-exact range, exclusion, wildcard, or compound requirement. Accept only exact selectors, including [email protected], pkg==1.2.3, and pkg@=1.2.3, and normalize each accepted selector to 1.2.3 before sidecar lookup and recording. Add parser, hook, and auto-record tests for npm, pip, Poetry, and Cargo.
