Plannotator v0.27.2

Plannotator is an open-source platform designed to review and validate plans and code generated by AI coding agents.

The platform provides a centralized interface where developers can:

• Review AI-generated plans

• Annotate proposed actions

• Approve or reject tasks

• Inspect code changes

• Provide structured feedback

• Improve agent outputs

• Maintain human oversight

Rather than replacing developers, Plannotator aims to keep humans involved in critical decision-making during AI-assisted development.

As AI coding agents become increasingly capable, developers face a growing challenge: ensuring that AI-generated plans and code changes align with project requirements before they are executed. Plannotator addresses this problem by acting as a review layer between developers and AI coding agents.

Instead of generating code itself, Plannotator focuses on making AI-driven development more transparent and controllable. It allows teams to review, annotate, approve, reject, and refine agent-generated plans and code changes before they affect a project.

This release ships a full mobile experience for plan review, code review, and annotation, alongside a security hardening pass, a fix for Codex review jobs on current Codex CLI versions, a large folder-mode performance win, and configurable markdown extensions. Fourteen PRs, including a community fix from @leoreisdias and a community-requested feature from @sgiath. Plan and code review on phones and tablets Review a plan from your couch. Approve a diff from the train. Plannotator's plan review, code review, and annotate surfaces now adapt to phones and tablets with a compact touch experience: full-width reading layouts, a full-screen navigator for files and contents, touch-safe comment composition that stays clear of the software keyboard, 44px touch targets, and safe-area-aware layouts that respect notches and home indicators. On iPhone Safari, plans use the browser's natural document scroll so the address bar collapses as you read. Desktop behavior is unchanged. The compact experience activates only on coarse-pointer devices at tablet widths and below, so a narrow desktop window keeps the workspace you know. Pair it with v0.27.0's --tailscale flag or remote mode and your phone becomes a first-class review device: start a review on your workstation, scan the QR code, and annotate from anywhere on your tailnet. This shipped as a five-part stack: viewport and safe-area foundation, keyboard-safe comment composition, touch and dialog primitives, the code review shell, and the plan shell. #1295, #1297, #1300, #1301, #1303 by @backnotprop Codex review jobs work again on current Codex CLIs Codex CLI 0.147.0 removed the --full-auto flag, which broke every Plannotator Codex review, Guided Review, and Code Tour job at launch with an argument error. Plannotator now passes --approve-for-me, the flag Codex introduced as its replacement, across all three job builders. Note the floor this implies: Codex review jobs now require codex-cli 0.147.0 or newer. Older Codex CLIs do not recognize the new flag. Thanks to @tgenov for independently reporting the breakage and pushing on a read-only sandbox for review jobs, an idea now tracked in #1310. #1231 by @leoreisdias Folder annotate opens in milliseconds on large repos Opening a folder annotate session initialized a file watcher across the entire .git/refs tree to keep git status live in the file browser. On repos with hundreds of branches and tags that took 9 to 23 seconds before the first file selection was responsive. The watcher now targets the five specific git files that drive status display (HEAD, index, the reflog, packed-refs, and the current branch ref), bringing cold start to about 30ms on the same repos with the same live status behavior. #1306 by @backnotprop Annotate any markdown-like file with configurable extensions Livebook notebooks, Quarto documents, and other markdown-dialect files were rejected by annotate because the accepted extensions were hardcoded. A new config-only setting registers extra extensions to treat as markdown: json { "markdownExtensions": [".livemd"] } in ~/.plannotator/config.json. Listed extensions are accepted everywhere annotate accepts .md: the CLI, the folder file browser, linked-doc and wiki-link navigation, frontmatter stripping, and version history. Entries are validated hard, and dotenv-family extensions can never be registered since annotate history copies file contents. Requested by @sgiath in #1307. #1309 by @backnotprop Security hardening across the supply chain Four security-focused changes landed in this cycle: Pi 0.79+ required. The Pi extension now requires Pi 0.79.1 or newer and refuses older hosts with a clear message instead of running with weaker project-trust behavior. If you are on an older Pi, update Pi first. #1291 Continuous scanning. Semgrep CE and Trivy now run on every PR and weekly in monitor mode, with fail-closed scanner health checks and pinned, checksum-verified tooling. #1294 Weekly DAST. An isolated OWASP ZAP passive scan runs weekly against a disposable annotate session on an internal-only network with no credentials and blocked egress. #1299 Marketing site on Astro 7. plannotator.ai moved from Astro 5 to 7.1.6, clearing eight dependency advisories. #1293 Additional Changes New reviewers start in Tree view. First-time code review users now land on the file tree instead of the Git status panel. Returning users keep whatever view they had. #1292 Quieter first run. The plan-AI, vim-mode, and analysis-layers announcement dialogs are gone, and automatic AI provider selection no longer persists anything until you explicitly choose a provider. Fewer interruptions before your first review. #1295 Install / Update macOS / Linux: bash curl -fsSL https://plannotator.ai/install.sh | bash Windows: powershell irm https://plannotator.ai/install.ps1 | iex Claude Code Plugin: Run /plugin in Claude Code, find plannotator, and click "Update now".

Key Features of Plannotator

Plan Review System

One of Plannotator's core capabilities is reviewing plans generated by AI agents before execution.

Developers can examine:

• Proposed tasks

• Implementation strategies

• Agent reasoning

• Planned file modifications

• Workflow sequences

This visibility helps reduce unintended changes and costly mistakes.

Annotation Tools

The platform allows users to add comments, notes, and guidance directly to AI-generated plans.

These annotations can be used to:

• Clarify requirements

• Correct misunderstandings

• Provide context

• Guide future agent actions

AI Code Review

Plannotator extends the review process beyond planning by supporting inspection of generated code.

Developers can:

• Review modifications

• Analyze diffs

• Leave comments

• Request revisions

• Validate implementation details

This workflow resembles modern pull-request review systems.

Human-in-the-Loop Workflows

A major design goal is ensuring that AI actions remain subject to human approval.

Organizations can establish review processes where important actions require validation before execution.

Open Source Foundation

Plannotator is open source, allowing teams to inspect, modify, and self-host the platform according to their needs.

This transparency is particularly valuable for organizations adopting AI-assisted software development.

User Experience

The interface is designed around review workflows rather than direct code generation.

Instead of interacting with a chatbot, users primarily:

1. Receive agent-generated plans

2. Review proposed actions

3. Add feedback

4. Approve or reject changes

5. Monitor execution results

The workflow feels familiar to developers accustomed to pull requests, code reviews, and project planning tools.

Productivity Benefits

As AI coding tools become more autonomous, review processes become increasingly important.

Plannotator helps organizations:

• Reduce risky AI actions

• Improve code quality

• Increase accountability

• Preserve architectural consistency

• Encourage collaboration between developers and AI agents

For teams adopting AI-driven development, these safeguards can be as valuable as the coding agents themselves.

Collaboration Features

The platform supports collaborative review workflows where multiple team members can participate in evaluating AI-generated outputs.

This allows:

• Peer review

• Team approval processes

• Shared annotations

• Collective decision-making

Such features are especially useful for larger engineering teams.

Performance

Because Plannotator focuses on workflow management and review rather than model inference, performance largely depends on the connected AI agents and integrations.

The platform itself is lightweight and primarily serves as an orchestration and review layer.

Open Source Advantages

Being open source provides several benefits:

• Transparent development

• Self-hosting capabilities

• Custom integrations

• Community contributions

• Vendor independence

Organizations concerned about compliance, security, or proprietary workflows may find these advantages particularly appealing.

Limitations

Plannotator is designed as a companion tool rather than a complete AI development platform.

Common limitations include:

• Requires external AI coding agents

• Best suited for teams already using AI-assisted development

• Smaller ecosystem than mature developer platforms

• Additional review steps may slow rapid prototyping

• Some users may prefer fully autonomous workflows

The software delivers the most value in environments where oversight and quality control are priorities.

Pros

• Improves transparency of AI-generated plans

• Supports structured review workflows

• Human-in-the-loop design

• Useful annotation system

• Open source

• Self-hosting support

• Familiar review experience for developers

• Helps reduce AI-generated mistakes

Cons

• Not a standalone coding agent

• Requires integration with AI development tools

• Smaller community than established developer platforms

• Adds review overhead to workflows

• Best suited for teams rather than casual users

Who Should Use Plannotator?

Plannotator is ideal for:

• Software development teams

• Engineering managers

• AI-assisted development workflows

• Organizations adopting coding agents

• Open-source projects

• Teams prioritizing code quality and governance

It is particularly valuable for environments where AI-generated code requires oversight before reaching production systems.

Plannotator fills an increasingly important role in the AI development ecosystem by providing visibility and control over AI-generated plans and code changes. Its focus on human oversight, structured reviews, and collaborative workflows makes it a useful companion for modern coding agents. While it is not a replacement for AI coding tools themselves, it offers a practical solution for teams seeking greater confidence and accountability in AI-assisted software development.
