Script runners (run, start, stop, restart, test, etc.) are not
package management commands — remove them so they go through the
proxy instead of being skipped.
* feat: add ProxyConfig struct with per-PM skip_commands and legacy fallback
* feat: consolidate proxy config into structured section with backward compat
Replaces flat proxy_mode/proxy_install_only keys with a structured proxy
section supporting per-package-manager skip_commands. Legacy keys are
respected via fallback when user's config lacks the new proxy section.
Removes deprecated experimental_proxy_mode config and flag.
* fix: env var resolution for nested config keys and deduplicate skip command matching
- Add "." to "_" in Viper env key replacer so nested keys like
sandbox.enabled resolve from PMG_SANDBOX_ENABLED (was silently broken)
- Export IsFirstNonFlagArgInList and remove duplicate from proxy_flow.go
- Add table-driven tests for skip command matching with real-world cases
- Remove redundant env var test
* docs: update proxy configuration and env var documentation
Update config.md env var table to reflect new proxy.enabled and
proxy.install_only keys. Add proxy configuration section to proxy.md
covering config structure, per-PM skip commands, CLI flags, and env vars.
* fix: legacy fallback precedence
* feat: Show cooldown report for pinned version installs
When a user installs a package with an explicit version (e.g.
npm install foo@1.2.3) and that version falls within the dependency
cooldown window, the cooldown block is now recorded and shown in the
report. Previously, the report only appeared when ALL versions of a
package were in cooldown (remaining == 0), causing pinned version
installs to fail with a confusing "version not found" error from the
package manager instead of a clear cooldown explanation.
Introduces InterceptorContext to carry per-execution data (pinned
versions) from the CLI command through the interceptor layer, keeping
it separate from long-lived dependencies like the analyzer and cache.
* fix: Normalize PyPI pinned version keys for cooldown lookup
CLI-provided package names (e.g. Flask_Cors) don't match the
URL-parsed form (flask-cors). Normalize keys once at construction
time so cooldown lookups match correctly.
* fix: Handle dots in PyPI package name normalization per PEP 503
denormalizePyPIPackageName already documented [-_.] replacement but
only handled underscores. Now also replaces dots with hyphens so
names like zope.interface match the URL-parsed form zope-interface.
* refactor: Extract shared cooldown stats recording into helper
Deduplicate identical stats-recording blocks from npm_cooldown.go
and pypi_cooldown.go into recordCooldownStats in cooldown.go.
* fix: Distinguish explicit version pins from auto-resolved versions
PyPI parsers resolve all packages to concrete versions (even without
a user-specified constraint), so HasVersion() was always true. Add
IsExplicitVersion to PackageInstallTarget, set it only when the user
provided an explicit constraint. Use it in proxy_flow.go to avoid
false pinned-version cooldown reports.
* feat: Add proxy_install_only config to restrict proxy to download commands
Introduces proxy_install_only (default: false) which, when enabled,
skips the proxy for package manager commands that do not download
packages (e.g. npm ls, pip list), avoiding unnecessary MITM overhead.
- Add ProxyInstallOnly to Config and config template
- Add IsKnownDownloadCommand / MayDownloadPackages to ParsedCommand
- Add DownloadCommands to npm and pypi PM configs covering update,
ci, audit, dlx, exec, x, download, run and equivalents per PM
- Extract shared runner.Execute used by both proxy flow and guard
- Proxy flow short-circuits to runner.Execute for non-download commands
when proxy_install_only=true
* refactor: Inject CommandExecutor into guard to fix dependency direction
guard depended on internal/runner, which inverted the intended layer
hierarchy. Now guard defines a CommandExecutor function type and accepts
it as a constructor argument. internal/flows (the composition root)
creates the executor closure wrapping runner.Execute and injects it,
keeping guard free of internal/ dependencies.
* refactor: Invert proxy_install_only logic to use known non-download commands
Replace the DownloadCommands allowlist (opt-in, fail-open) with a
NonDownloadCommands denylist (opt-out, fail-safe). The proxy now runs
for all commands except those explicitly known to not download packages.
Unknown or future package manager subcommands default to running with
the proxy.
Includes script runners (run, start, test, stop, restart) that can spin
up local servers — setting proxy env vars on these breaks them without
providing any security benefit. Also covers removal commands and local
operations that never contact the registry.
* fix: Support PMG_* env vars regardless of config file state
AutomaticEnv only resolves env vars for keys Viper already knows about
via AllKeys(). When a key is absent from the config file (commented out,
new key added after last setup, or no config file at all), Viper had no
knowledge of it and silently skipped the env var.
Fix by registering all Config struct fields as Viper defaults via
reflection (using mapstructure tags) before reading the config file.
This ensures PMG_* env vars work in all cases.
Precedence: cobra flags > env vars > config file > defaults.
SetDefault is used (not Set) so env vars and config file can still
override the Go defaults freely.
Tests added covering all precedence levels including the key-absent-
from-config-file case that was the original bug report.
* fix: Only check first non-flag arg against NonDownloadCommands
Scanning all args caused false proxy bypasses when package names or
script arguments matched a NonDownloadCommands entry. For example:
- npm exec test → "test" matched, proxy incorrectly skipped
- npm update config → "config" matched, proxy skipped
- npm publish --tag version → "version" matched, proxy skipped
Fix by checking only the first non-flag argument (the subcommand).
If it is not in NonDownloadCommands we break immediately, so trailing
args never influence the classification. Applied to all four parsers:
npm, pip/pip3, uv, and poetry.
Regression tests added for the false positive cases.
* refactor: Replace reflection-based Viper defaults with embedded template
Load the embedded config template as the Viper base so all keys are
registered upfront, enabling PMG_* env vars to work regardless of
whether a key exists in the user's config file.
* fix: Restore trusted_packages template entry and revert DefaultConfig change
* docs: Document environment variable overrides for config keys
* update npm test cmd
* refactor: extract shared non-download command detection helper
Replaces duplicated first-non-flag-arg detection loops in npm.go and
pypi.go (pip + poetry parsers) with a shared isFirstNonFlagArgInList
helper in packagemanager.go.

* fix: only strip own package manager name in ParseCommand args
ParseCommand was stripping the first arg if it matched any package
manager name (npm, pnpm, bun, yarn). This caused yarn's parser to
incorrectly strip "npm" from "yarn npm login", since "npm" is a
valid yarn subcommand, not a package manager prefix.
