What it does

Plan Review is an agent skill from KenjiOhtsuka/harmonica. Use when reviewing the Harmonica restart plan against reality — after a phase PR or milestone merges, before proposing the next phase, or when asked "are the specs up to date" / "what should we do next". Reconciles spec/plan.md, spec/tech-notes.md, and spec/issues-triage.md with the actual repo (git log, GitHub issues/PRs, dependency versions, test counts), applies updates to spec/, then verifies with the spec-review agent.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Databases, covering Project management, Database migrations and Android development. It works with Git, Gradle, GitHub and Kotlin. The repository describes itself as: Kotlin Database Migration Tool. This tool makes it really easy to create table, index, add columns, and so on, with Kotlin DSL. The licence is MIT.

When your agent uses it

  • Reviewing the Harmonica restart plan against reality — after a phase PR
  • Milestone merges
  • Before proposing the next phase
  • Asked are the specs up to date / what should we do next

Example prompts

  • “are the specs up to date”
  • “what should we do next”
  • “/plan-review”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Gather ground truth
  2. Diff the docs against ground truth
  3. Apply updates
  4. Verify
  5. Open a PR
  6. Report

What it can do on your machine

Read from SKILL.md and the folder at commit 32e06c9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • gh
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use gh and git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Plan Review loads about 1k tokens when it runs. Until then it costs about 110 tokens; SKILL.md has 516 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~110
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use when reviewing the Harmonica restart plan against reality — after a phase PR or milestone merges, before proposing the next phase, or when asked "are the specs up to date" / "what should we do next". Reconciles spec/plan.md, spec/tech-notes.md, and spec/issues-triage.md with the actual repo (git log, GitHub issues/PRs, dependency versions, test counts), applies updates to spec/, then verifies with the spec-review agent.

Plan Review

The spec/ planning docs are the source of truth and go stale every time a phase PR merges. This workflow reconciles them with reality: gather ground truth, diff the docs, apply updates, verify. Edit spec/ only; every change goes through a small PR against develop, never a direct push.

When to run

  • After any phase PR or milestone merge.
  • Before proposing the next phase of work.
  • When the user asks "are the specs up to date?" / "what should we do next?".

Scope

Keep in sync: spec/plan.md, spec/tech-notes.md, spec/issues-triage.md. Do not touch spec/ci.md, spec/testing.md, spec/exposed-integration.md, or spec/README.md unless a finding specifically requires it.

Steps

1. Gather ground truth

Run these and record the results before touching any doc:

  • git fetch origin then git log --oneline origin/develop -15 — recent merges.
  • gh pr list --state open and gh pr list --state merged --limit 25 — PR states.
  • gh issue list --state open — note the exact open count.
  • Grep versions from the build: gradle/wrapper/gradle-wrapper.properties, gradle.properties, root/core/gradle-plugin build.gradle.kts, settings.gradle.kts (wrapper, kotlin, junit, plugin-publish, dokka, test deps).
  • ./gradlew test (JDK 25, this machine) for the authoritative test count and build health. Static @Test grep counts drift from the real JUnit count — trust the Gradle output, not the source grep.
2. Diff the docs against ground truth

For each of the three docs, find every claim that disagrees with reality:

  • plan.md: phase status blocks (implemented/merged, PR numbers, dates, test counts); the phase checklists; §6 resolved/open decisions; §3 branch strategy notes.
  • tech-notes.md: dependency table rows still marked pending/untouched that are now DONE (add the PR ref); self-contradictions between a table row and a later note; test counts; repository/protocol notes.
  • issues-triage.md: the open-issue count in the header (re-snapshot); issues resolved by the work (move them out of the active table, note the closing PR); new issues created since the snapshot (add them); stale cross-references.

Cross-check the three docs against each other — no contradictions.

3. Apply updates
  • One logical change per edit; preserve the existing style and table format.
  • Mark resolved issues as resolved in the docs with the PR reference, but do not close the GitHub issues — that is a separate user decision.
  • Update the "Snapshot ... <date>" header in issues-triage.md to the actual review date and the current open-issue count.
4. Verify
  • Delegate a final pass to the spec-review agent (read-only) against the updated docs. Fix any BLOCKER/WARNING findings it reports.
5. Open a PR
  • Commit, push, and open the PR only when the user has explicitly asked for the reconcile to land as a PR; otherwise present the edits and ask first.
  • Commit the spec changes on a docs/... branch cut from the current origin/develop (fetch first; never cut from a sibling unmerged branch).
  • Push it and open a small PR against develop titled around what the reconcile covers.
  • Do not close GitHub issues yourself — that remains a user decision; list in the PR body the issues this reconcile marks as resolved, with the PR that resolves each.
6. Report

Summarize: what changed in each doc, the PR URL, the authoritative test count, and a list of GitHub issues the user should close.
