Closes #132

Adds an .editorconfig to enforce:

  • Tabs for .go files
  • 2 spaces for .yml, .yaml, and .md files
  • LF line endings, final newlines, and trimming trailing whitespace.

Summary by CodeRabbit

  • New Features
    • Plans returned by the provider are checked against the request and allowed actions before execution. Invalid or disallowed plans return a bounded error.
  • Bug Fixes
    • Clearing the terminal now also clears its accumulated output.
  • Documentation
    • Updated the host bridge guide to clarify plan validation and how invalid requests and plans are handled.
  • Chores
    • Example build, Docker, and test workflows now stop when a command fails or a required variable is missing.
    • Markdown files now follow the shared whitespace formatting rule.

📝 Walkthrough

Walkthrough

The change adds constrained provider-plan parsing and validation to the host bridge, expands shell command tests, and resets accumulated terminal output when Clear runs. It also updates EditorConfig rules and enables strict error handling in three example scripts.

Changes

EditorConfig rules

Layer / File(s) Summary
EditorConfig whitespace rules
.editorconfig
Markdown now uses the global trailing-whitespace setting. Explicit indentation rules for shell scripts, Makefiles, and Python were removed. Go and YAML indentation settings remain.

Example script error handling

Layer / File(s) Summary
Enable strict shell options
examples/build_and_run.sh, examples/run_docker.sh, examples/test_all.sh
All three scripts now enable errexit, nounset, and pipefail.

Provider plan validation

Layer / File(s) Summary
Define prompt and plan validation
scripts/agent_bridge_planner.py
The planner defines recognized action contracts, validates requests and provider content, and checks plan fields, actions, arguments, and UTF-8 size limits.
Connect provider and bridge validation
scripts/agent_bridge_provider.py, scripts/agent_bridge.py, scripts/test_agent_bridge.py, docs/v0.6.0/host_bridge.md
The provider uses the planner’s prompt and parsing functions. The bridge validates plans against requests and encodes planner errors. Tests cover valid and invalid plans, and the documentation describes the validation boundaries.

Shell command and terminal behavior

Layer / File(s) Summary
Cover shell commands and history
shell/shell_test.go, terminal/stubs.go
Tests cover built-in commands, filesystem operations, error cases, suggestions, and command history. Clear now also clears accumulated output.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Feature

Suggested reviewers: dmarro89

Merge Risk: 🔵 Low · up to 6a545

The change is mergeable with awareness that saving Markdown files may remove intentional line breaks. No affected hard break was found in the current files.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 6a545

The change strengthens provider-response validation without a demonstrated expansion of execution privileges. The main remaining uncertainties concern host-to-guest compatibility, target authorization, and recovery behavior.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — Within the inspected consumer, provider influence is constrained to guest-advertised actions and target values passed to configured handlers, rather than arbitrary shell execution. File reads and confirmed deletion are sensitive outcomes; the maximum accessible filesystem scope cannot be determined without the concrete adapter and handler authorization policy.

Trust Boundaries and Controls

  • observed — Input and context are placed in a user message, while the selected action contracts are supplied separately. The security control is deterministic response validation, not the instruction to treat input as untrusted. Guest validation and confirmation remain downstream controls.

Resilience and Maintainability Implications

  • observed — Planning failure returns before execution. Risky plans enter pending confirmation; confirmation or cancellation consumes that pending plan, and confirmed execution revalidates it. A repeated confirmation without pending state is rejected. Executor failure returns immediately, but these functions do not establish durable recovery or compensation for handler-side effects.

Hardening Proposals

  • proposed — As a follow-up, explicitly bind pending confirmation to a request identity and define its replacement or expiration when a new request begins. BeginRequest does not clear PendingPlan or ConfirmationPending. This is a state-lifecycle hardening proposal, not an established PR-introduced vulnerability.

Preserve Markdown hard breaks when trimming whitespace.

When a Markdown line uses two trailing spaces for a hard break, an editor that honors this rule removes them on save. Markdown then renders a soft break instead. Add a Markdown-specific override or require a hard-break form that survives trimming.

Restore the Makefile tab rule.

The head .editorconfig no longer requires tabs for Makefile. An EditorConfig-compliant editor with a spaces default can therefore insert spaces before a new recipe. Makefile does not define .RECIPEPREFIX, so GNU Make can reject that recipe with “missing separator”.

Not ready to merge. I compared the prospective merge with current main. EditorConfig is already in #200. This merge would remove the Markdown hard-break exception and the Makefile tab rule, and it would also change three example scripts. The original issue is covered. The script changes are tracked separately in #202.

Closing this - the EditorConfig is already on main via #200.
