Plannotator v0.27.4

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 portable guide exports, share links on guides.show, and a guide CLI any agent can drive, alongside a favicon style switcher, jj support for Call Flow, GitLab artifact fixes in PR review, and a smoother call-flow Lens. Eighteen PRs, four from community contributors, two of them first-timers. Portable Guided Reviews and guides.show Guided Reviews used to live and die inside your review session. Now a guide has three ways out: Download it. Every guide gets a "Download portable guide" button that produces one HTML file containing the full guide and the diff it describes. It opens anywhere, renders exactly like the in-app guide with side-by-side diffs and per-section reviewed checkboxes, and needs no Plannotator install. The file stays small because it carries your content, not the renderer: the viewer loads from guides.show, pinned by filename and cryptographic checksum, so a tampered or wrong viewer never executes. Offline, the file degrades to a readable plain-text version of the guide. Share it. "Create share link" uploads the guide to guides.show and hands you a link anyone can open in a browser. Shares are end-to-end encrypted by default: the key lives in the URL fragment after the #, which browsers never send to the server, so guides.show stores bytes it cannot read. You also get a one-time delete token, and "Remove link" works from the same dialog for as long as that Plannotator remembers the share. An optional "Allow link previews" checkbox stores the guide unencrypted so chat apps can show its title; that is a choice, never the default. Setting PLANNOTATOR_SHARE=disabled turns all of this off. Author it from anywhere. The new plannotator guide subcommands (list, export, share, unshare) let any agent or script produce and publish a guide from a guide JSON and a patch, without a browser in the loop. Saved guides from v0.27.x load unchanged. The share service runs on Cloudflare with add-only, content-hashed viewer publishing and per-IP rate limiting on creation. #1324, #1327, #1328, #1329, #1330, #1336, #1337 by @backnotprop Choose your favicon: Totman or the classic P The browser-tab icon is now a setting. Appearance settings offer two styles with visual previews: Totman, the current mascot, and Classic P, the original Plannotator mark restored byte-for-byte from the pre-mascot era. The server remembers your choice and serves it directly, so tabs show the right icon from the first paint without flashing the default. Hosts that embed the published UI packages are unaffected unless they opt in. #1325 by @FNDEVVE Call Flow analysis on jj repositories Call Flow previously required a plain Git checkout. Reviews running on jj (Jujutsu) colocated repos now get the same changed-call-path analysis: the jj snapshot is resolved to the underlying Git objects and fed to the same CallDiff engine, with the same per-file Lens and dock views. Diff collection is untouched; this only extends where the analysis can run. #1312 by @graemefolk GitLab PR artifacts fetch reliably and more safely Reviewing GitLab merge requests with uploaded artifacts (screenshots, logs, design files) got a hardening pass. Uploads now fetch through the authenticated API with a strict rewrite that only touches real upload URLs, falls back to the original web route when a self-hosted GitLab predates the API route, maps 401/403 responses to a clear "run glab auth login" hint, and no longer serves HTML or JavaScript content types through the artifact proxy. A regression test pins the invariant that credentials never follow a cross-origin redirect. #1228 by @yuensunn The call-flow Lens stops fighting your scroll Community feedback within hours of trying Call Flow in Safari: the per-file Lens popover closed randomly mid-scroll and popped open for every badge that passed under the cursor. Three causes, three fixes: the Lens's internal scroll no longer chains to the page when momentum hits its edge (the chain moved the popup out from under a stationary pointer, which read as a random close and was worst under Safari rubber-banding); hover now has a 100ms intent delay so drive-by badges stay closed; and an in-flight page scroll holds any pending close until the scroll settles. Reported by Rustan (@acewhocares on X). #1338 by @backnotprop Additional Changes Touch selection survives the comment composer. On phones and tablets, dragging a multi-line range in a single-file diff no longer collapses the selection when the composer opens; the range you dragged is the range you comment on. #1333 Skill picker works with screen readers. The / and $ skill reference menu now exposes real listbox semantics with option roles and active-descendant tracking, so assistive tech announces what Enter will insert, closing #1233. #1316 by @ashish921998 Blog: an interactive UI for the grill-me skill.

Their second contribution. @graemefolk extended Call Flow analysis to jj repositories in #1312, their third contribution to Plannotator's jj support, which they have carried since the original provider landed. @yuensunn fixed GitLab merge request artifacts in #1228, their first contribution, and stuck with it through a security-focused review round on the URL rewrite. @ashish921998 made the skill reference menu real for screen reader users in #1316, their first contribution. Rustan (@acewhocares on X) test-drove Call Flow in Safari and reported the Lens scroll behavior that #1338 fixes, hours after trying the feature.

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.
