* feat(uvx): add uvx (uv tool run) package executor
Adds support for `uvx`, implemented as a PyPI Executor alongside pipx.
uvx is an alias for `uv tool run`: it installs a tool into an ephemeral
environment and runs it, so it has no install/list subcommand and the
first positional argument (or --from) is the package to audit.
Parsing highlights:
- --from overrides the positional command as the package to audit
- --with packages are audited as additional environment dependencies
- name@version shorthand (ruff@0.3.0, ruff@latest) is normalized
- flag parsing stops at the tool name so the tool's own flags are not
misread as uvx options; uvx's value/boolean flags are registered so
none greedily consume the package positional
- VCS/URL/local-path specs are skipped for registry auditing
Wires up command registration, analytics, shell alias/shim, cloud audit
mapping, a dedicated `uvx` sandbox profile (UV_*/PIP_* env, uv cache and
tool dirs), config policy, docs, unit tests and an E2E workflow step.
Closes#326https://claude.ai/code/session_011hyLxq7oWJX5Dp4tCEfG19
* chore(uvx): align docs and base profile with uvx support
Incorporates the low-risk, non-parser improvements from the community
PR #345 (author non-responsive) into our implementation:
- list uvx (and the previously-missing pipx) as PyPI managers in the
pypi-restrictive base profile package_managers and its README, so the
base profile applies directly when selected via --sandbox-profile
- document uvx in docs/github-action.md and docs/proxy-mode.md
- add version / IsExplicitVersion assertions to the uvx parser tests
Our pflag-based parser is kept as-is: unlike #345 it audits --with
packages and handles all uvx short flags (e.g. -w), both of which the
community PR misses.
* fix(uvx): skip interpreter requests; use require in tests
Addresses review feedback on PR #357:
- uvx interpreter requests (`uvx python`, `uvx python@3.12`, `uvx pypy`,
...) launch an isolated interpreter rather than installing a PyPI tool.
Treating the positional as a package made the guard flow resolve/analyze
pkg:pypi/python (and python==3.12), which could wrongly block or fail a
valid invocation. Skip these for the positional; --with packages on the
same command are still audited.
- Use require.NoError / require.Len for fatal assertions in the uvx tests,
matching the repo's testing convention, so a failure stops the subtest
before a nil dereference instead of panicking.
* docs(uvx): document fail-open and --with-requirements trade-offs
Record the two deliberate parsing decisions raised in review as in-code
trade-off comments (no behavior change):
- unknown flags are tolerated (fail open), consistent with the other
executors; the residual gap only affects non-proxy guard mode since the
default proxy flow intercepts every registry download.
- --with-requirements / --with-editable values are consumed but not
expanded into audit targets; expanding them needs manifest-extractor and
guard changes, tracked as follow-up. Proxy mode still covers them.
* docs(uvx): drop --with-requirements limitation note
Per maintainer review: guard mode is being deprecated and auditing the
contents of an existing requirements file is a scanner's responsibility,
not PMG's. Remove the "known limitation / follow-up" note; the flags stay
registered only so their values are not mistaken for the tool positional.

* feat(cooldown): respect trusted_packages in dependency cooldown
Trusted packages are now treated as a superset waiver that bypasses every
PMG control (malware analysis, cooldown, and any future controls). A
globally trusted package is automatically exempt from the cooldown window
and no longer needs a duplicate entry in dependency_cooldown.skip.
The skip list remains the narrower, cooldown-only waiver for packages
that must bypass the cooldown wait but still be malware-scanned.
* refactor(cooldown): tag skip reason and audit-log skipped packages
Address review feedback on #342:
- Restore cooldownSkip to a pure single-list function (SRP); the merge
into trusted_packages now happens in a separate mergeCooldownSkip step,
driven by the exported CooldownSkip wrapper.
- Extend CooldownSkipInfo with a CooldownSkipReason (TrustedPackage /
CooldownSkipList) on both SkipAll and per-version entries, so callers
can tell apart the broad waiver from the cooldown-only one. When both
lists match the same package, trusted_packages wins.
- Add audit.LogCooldownSkipped and emit it from the npm and PyPI
interceptors on the SkipAll path, alongside the existing info log,
carrying the source list as the reason.
* refactor(cooldown): inline list merge, audit per-version exemptions
Address further review feedback:
- Drop the separate mergeCooldownSkip helper; cooldownSkip now writes
into a shared *CooldownSkipInfo and is called twice from CooldownSkip
(cooldown skip list first, trusted_packages on top so trusted entries
override the reason on overlap).
- Audit log every exemption, not just SkipAll: a new auditCooldownSkip
helper in proxy/interceptors/cooldown.go emits one event per match
(package-wide or per-version), each tagged with its source list.
LogCooldownSkipped gains a version argument for the per-version case.
- Cover the trusted_packages reason path in TestCooldownSkip.
* fix(cooldown): avoid double-auditing trusted package exemptions
auditCooldownSkip now only emits EventTypeCooldownSkipped for entries
that came from dependency_cooldown.skip. Trusted-package exemptions
already get an EventTypeInstallTrustedAllowed event at tarball-download
time (proxy/interceptors/base_registry.go), so emitting a cooldown event
for them too would double-count the same waiver.
* emit trusted and cooldown skip events to cloud
* fix tests
* refactor(cooldown): return value from collectCooldownSkip, short-circuit on trusted SkipAll
Address PR review feedback:
- Rename cooldownSkip to collectCooldownSkip and return CooldownSkipInfo
instead of mutating an input pointer.
- Add mergeCooldownSkip to combine per-list results with trusted_packages
taking precedence on overlap.
- CooldownSkip now consults trusted_packages first and returns immediately
on a package-wide trusted exemption (DC skip list cannot add anything).
- Extend tests to cover disjoint pinned entries across both lists and the
case where DC version-less subsumes a trusted pinned entry.
* fix(audit): address cooldown review feedback
* fix(cooldown): audit cooldown skips at download time with concrete version
Backend rejects PackageVersion messages without a version, and audit logs
should reflect the runtime fact (a specific version was skipped) rather
than the config rule. Move the audit emission from metadata-request
handling to download-request handling, where the concrete version is
known, and require version in LogCooldownSkipped.
* chore(audit): drop dead scope assignment in LogCooldownSkipped
* refactor(cooldown): move skip-list logic into cooldown handlers
Registry interceptors no longer compute CooldownSkip or branch on SkipAll;
they just call HandleMetadataRequest. The npm and pypi cooldown handlers
own the skip lookup, the package-wide exemption short-circuit, and (for
pypi) the canonical-name denormalization. Also align LogCooldownSkipped
with other LogXxx signatures by taking *packagev1.PackageVersion.
* fix: Simplify audit logging for dependency cooldown skip
* refactor: Simplify cooldown handling and maintain separation of concepts for trusted and DC skip packages
* fix: Code review fixes
* fix: Emit cooldown skipped audit event ONLY when an in-window version is skipped

* feat: emit cloud events for dependency cooldown and host observations (#237)
Wire cooldown blocks and proxy host observations through the cloud sync
pipeline so they appear as telemetry in Control Tower.
- Cooldown blocks emit PACKAGE_DECISION with COOLDOWN_BLOCKED action and
PmgDependencyCooldown context (publish date, cooldown days, days since
publish, days remaining)
- Proxy host observations emit HOST_OBSERVATION with PmgHostObservation
(hostname, method)
- Session summary now includes cooldown_blocked_count
- Updated buf API dependency for new proto schema

* fix: add explicit eventlog mapping for EventTypeDependencyCooldown
Follow the existing pattern where every audit event type has an explicit
case in mapEventType and a corresponding constant in the eventlog package.
