Summary

  • implicitly trust and persist active config for mise run, mise install, mise exec, and mise watch in non-paranoid mode
  • keep automatic hook-env and inspection commands behind the existing trust boundary
  • preserve explicit trust requirements in paranoid mode and avoid trust writes in safe mode
  • update trust documentation and regression coverage

Why

These commands explicitly execute project-defined behavior, so invoking them is already a strong indication that the user accepts the active config. Persisting trust avoids a redundant prompt while keeping automatic shell activation conservative.

Validation

  • mise run lint-fix
  • mise run test:e2e e2e/config/test_non_paranoid_implicit_trust e2e/config/test_trust_safe_config e2e/cli/test_hook_env_untrusted_once_per_dir e2e/cli/test_prune_tracked_config_trust e2e/tasks/test_task_untrusted_config_error
  • mise run test:e2e e2e/config/test_safe_mode e2e/config/test_non_paranoid_implicit_trust
  • cargo test --locked --bin mise test_commands_that_implicitly_trust_active_config
  • mise run render:usage

AI-assisted — Tool: Codex; model: unavailable; version: unavailable.


Note

Medium Risk
Changes security-sensitive config trust boundaries for common execution paths; mitigated by paranoid/safe/CI/ignore exclusions and broad e2e coverage.

Overview
Normal mode now treats running project-defined behavior as consent to load the active config: after CLI parse, mise run, naked mise <TASK>, mise install, mise exec, and mise watch set an implicit-trust flag, call trust_active_config() to persist trust for discovered non-global configs, and extend trust_check to trust on load when appropriate. hook-env, env, ls, and similar commands are unchanged.

Guards: no implicit trust in paranoid or safe mode, on CI, or for ignored configs. mise untrust / --untrust copy now says they remove explicit trust.

Docs (trust FAQ, getting started, paranoid) and usage/man pages describe automatic vs explicit trust. E2E tests cover implicit trust, safe configs creating markers on run/install, and paranoid still requiring prompts.

Summary by CodeRabbit

  • New Features

    • Commands that execute project behavior automatically trust the active configuration in normal mode.
    • Paranoid mode requires explicit trust; safe configurations can be inspected without creating trust markers.
    • mise untrust and --untrust remove explicit trust.
    • Environment hooks do not automatically trust configurations.
  • Documentation

    • Clarified configuration trust rules, safe configurations, automatic trust, paranoid mode, and non-interactive behavior.
  • Tests

    • Expanded coverage for implicit trust and untrusted configurations.

📝 Walkthrough

Walkthrough

The CLI now implicitly trusts active project configurations for exec, install, run, watch, and naked tasks in normal mode. Paranoid mode and unsafe configuration checks remain explicit. Tests and documentation describe the updated behavior.

Changes

Implicit configuration trust

Layer / File(s) Summary
Trust state and checks
src/config/config_file/mod.rs
Adds process-wide implicit-trust state, active-config trust handling, and automatic trust persistence for eligible configurations.
CLI command classification and startup
src/cli/mod.rs
Classifies commands that imply trust, applies the setting during startup, and tests command behavior.
End-to-end trust behavior
e2e/config/*, e2e/cli/*, e2e/tasks/*
Validates normal-mode trust, safe-config loading, trust removal, tracked configurations, hook-env behavior, and paranoid-mode rejection.
Trust command and behavior documentation
docs/cli/*, docs/faq.md, docs/getting-started.md, docs/paranoid.md, docs/public/llms.txt, mise.usage.kdl, man/man1/mise.1, src/cli/trust.rs, src/cli/untrust.rs
Updates trust rules, safe-config criteria, paranoid-mode behavior, and explicit trust removal descriptions.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 56a12

This change localizes implicit trust persistence to explicit execution commands while preserving the documented safe and paranoid-mode boundaries; no actionable merge-blocking risk remains after normal checks and review.

Poem

A rabbit checks the config gate,
Then hops through commands without wait.
Paranoid mode keeps trust in sight,
Safe files load by day or night.
Explicit trust can still be cleared.
The burrow’s rules are now well-geared.

Greptile Summary

The PR makes explicit execution commands implicitly trust and persist their active project configuration in normal mode while preserving paranoid-mode, safe-mode, ignored-config, CI, and shell-activation boundaries.

  • Classifies run, naked tasks, install, exec, and watch as implicit-trust commands.
  • Persists active configuration trust during startup and allows unsafe configuration loading on those explicit command paths.
  • Updates trust documentation, generated usage material, and regression coverage.

Confidence Score: 5/5

The PR appears safe to merge because no blocking failure remains within the eligible follow-up-review scope.

No blocking failure remains.

Important Files Changed

Filename Overview
src/cli/mod.rs Classifies explicit execution commands and naked tasks for implicit trust, then persists active-config trust after settings initialization.
src/config/config_file/mod.rs Implements implicit active-config trust while retaining safe-mode, paranoid-mode, ignored-config, and CI protections.
e2e/config/test_non_paranoid_implicit_trust Covers normal-mode implicit trust and verifies the intended ignored-config, CI, and paranoid-mode boundaries.
docs/cli/trust.md Documents which commands automatically trust configuration and distinguishes normal mode from paranoid mode.

only as plain version strings or arrays of strings, excluding tool-option tables
and other top-level settings. Scope non-interactive pre-trust guidance to
commands other than normal-mode mise run, mise install, mise exec, and mise
watch, which automatically trust the active config.

In `@e2e/config/test_non_paranoid_implicit_trust`:
- Around line 29-36: Add persisted-trust verification to the test after both the
mise run and mise exec commands by invoking mise trust --show and asserting the
expected trust state, then remove the trust marker afterward to preserve test
isolation. Keep the existing command-output assertions unchanged.

In `@src/config/config_file/mod.rs`:
- Around line 394-401: Update the implicit-trust loop around
config::load_config_paths so it skips any path ignored at either the
configuration-file or config-root level before calling trust; preserve existing
global-config handling and trust only non-ignored roots. Add a regression test
covering Settings::try_get followed by an implicit-trust command, asserting that
an ignored safe configuration remains ignored.

Instruction counts

Nothing was compared, and so nothing was gated. No series appears on both sides: either the base has no measurements recorded, or the two were measured on different runner classes, which are deliberately not comparable — counts shift between machine types by more than a real regression does.

New, nothing to compare against: env on bamboo-v2-ubuntu24.04-x64-30vcpu-24gb-rust1.97.1, hook-env on bamboo-v2-ubuntu24.04-x64-30vcpu-24gb-rust1.97.1, ls on bamboo-v2-ubuntu24.04-x64-30vcpu-24gb-rust1.97.1, registry on bamboo-v2-ubuntu24.04-x64-30vcpu-24gb-rust1.97.1, startup on bamboo-v2-ubuntu24.04-x64-30vcpu-24gb-rust1.97.1

Only instruction counts gate. Wall clock is shown for context — on identical hardware it moves 4-20% run to run.

Measured by tak — instruction-counted CLI benchmarks, stored in this repository's git notes.

56a1229f07fd vs 82ca17ec5e85 · measured on the runner, not pushed to the history.

Preserve the existing statement that paranoid mode always requires explicit,
content-bound trust.

documentation to qualify that explicit, content-bound trust is required except
for safe configurations. Keep the following definition of safe config files
consistent and unchanged.
