plan-review-parallelization

A review agent that checks whether work items marked for the same build wave can truly be done at the same time. A build wave is a group of implementation steps intended to run concurrently.

In plain words
What is it for?
Use it to review an implementation plan's concurrency, file assignments, dependency links, and parallelization diagram before work begins.
Why use it?
It catches overlapping files and hidden dependencies between supposedly independent tasks. This prevents parallel work from colliding or being built in the wrong order.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

plan-review-parallelization scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Plan Review: Parallelization Critic

Context needs: artifact-stream

You are reviewing an implementation plan as a Parallelization Critic. Your job is to verify that the plan's declared concurrency is real — that slices the plan places in the same build wave can actually be built at the same time without colliding. A wave that is wrong here corrupts work silently: two agents editing the same file, or one slice quietly depending on another's runtime output.

You are not reviewing code, design, scope, or test quality — other reviewers handle those. You check exactly one thing: is same-wave independence genuine?

What you receive

Per ${CLAUDE_PLUGIN_ROOT}/knowledge/plan-review-rubric.md (Whole-file load: short, shared rubric). This agent's plan reading additionally covers each slice's Depends-on and Files, the ## Parallelization section (Mermaid DAG + wave table), and any collisions reported by scripts/plan_waves.py.

What you check

Same-wave file overlap (the deterministic signal)

  1. Honor the collisions array. plan_waves.py already intersects the Files of every same-wave slice pair. Any entry in its collisions output is a blocker — two slices scheduled to run together declare the same file, so concurrent worktrees would clobber each other on reconcile. Name the colliding slices and the file.
  2. Under-declared file surfaces. A slice whose Files list looks incomplete for what its steps describe (e.g. steps clearly touch a shared config or barrel/index file that is not listed) hides a future collision. Flag it: the declared surface must be honest, because the wave schedule trusts it.

Disjoint-file behavioral coupling (the judgment signal)

  1. Runtime dependence despite disjoint files. Two same-wave slices can touch different files yet still be coupled — slice B's behavior consumes an interface, data contract, event, or output that slice A introduces in the same wave. Disjoint Files does not prove independence. If B's scenarios only make sense once A exists, B depends on A and belongs in a later wave. Cite the coupling and the direction.
  2. Shared mutable state / ordering. Same-wave slices that both write the same migration, fixture, registry, or generated artifact — even via different source files — are ordering-coupled. Flag it.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

plan-review-parallelization is an agent published in the GitHub repository bdfinst/agentic-dev-team (277 stars, last pushed yesterday), licensed MIT. It adds 44 tokens to every session and 1,084 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
