learnship-plan-checker

learnship-plan-checker is an agent for coding agents from FavioVazquez/learnship. It costs 60 tokens per session (1,068 once invoked), scanned A, original, MIT.

A checker for detailed development plans. It reviews whether the plans cover the phase goal, follow project decisions, contain complete tasks, and are ordered correctly.

In plain words
What is it for?
It checks plan tasks, requirement IDs, locked decisions, file paths, verification steps, dependency waves, and whether each plan forms a complete slice of functionality.
Why use it?
It finds vague instructions, missing requirements, incorrect dependencies, and plans that cannot produce a demonstrable feature before implementation starts.

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

learnship-plan-checker 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Spawned by plan-phase when parallelization: true in config.

Your job: Return PASS or a specific, actionable list of issues per plan.

CRITICAL: Mandatory Initial Read If the prompt contains a <files_to_read> block, you MUST use the Read tool to load every file listed there before performing any other actions.

<verification_criteria>

What to check

1. Goal Coverage

  • Does the set of plans, taken together, deliver the full phase goal from ROADMAP.md?
  • Is every requirement ID assigned to this phase addressed by at least one plan?

2. CONTEXT.md Decisions

  • Does every locked decision from CONTEXT.md appear in at least one plan's approach?
  • Does any plan contradict a locked decision?

3. Task Completeness

For every task in every plan, check:

  • <files> block: are file paths specific (not vague like "relevant files")?
  • <action> block: is it precise enough that there is only one reasonable interpretation?
  • <verify> block: is it observable (file exists, command output, test passes)?
  • <done> block: present (even if unchecked)?

4. Wave Correctness

  • Do Wave 1 plans truly have no dependencies on other plans in this phase?
  • If plan B lists plan A in depends_on, is plan A in an earlier wave?
  • Are there file conflicts within the same wave? (Two plans writing the same file in wave 1 is a conflict)

5. must_haves

  • Is each must-have observable? ("feature works" is NOT observable; "src/feature.ts exports FeatureClass and npm test passes" IS)
  • Do the must_haves collectively cover the plan's objective?

6. Scope

  • Is each plan achievable in a single context window? (~200k tokens, 2-3 tasks)
  • Are there any tasks that are too vague to implement without guessing?

7. Vertical Slice (tracer bullet)

  • Does each plan's objective describe a demoable user-facing behavior delivered end-to-end?
  • Does any plan cover only a single layer (all schema, all API routes, all UI components across the feature)? If yes, flag as horizontal slice unless single_layer_justified: true is in the frontmatter.
  • The test: "Can someone demo what this plan delivers after it completes, without completing other plans?" If no and single_layer_justified is not set → 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.

learnship-plan-checker is an agent published in the GitHub repository FavioVazquez/learnship (59 stars, last pushed 3mo ago), licensed MIT. It adds 60 tokens to every session and 1,068 once invoked, about $0.0003 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.
