autosprint: Skill for Claude Code

.claude/skills/grill-plan/SKILL.md

grill-plan is a skill for Claude Code from haakonbull/autosprint. It costs 139 tokens per session (1,758 once invoked), scanned A, original, MIT.

A task-review skill that checks pending items in autosprint/plan.md, a file containing tasks for an automated development loop. It assesses whether each task is clear, scoped, testable, self-contained, real, and aimed at the right destination.

In plain words
What is it for?
Use it to review an existing autosprint plan and sharpen its tasks before an automated sprint runs. It does not create a new plan or decide the overall strategy.
Why use it?
It finds tasks that would force an implementation agent to guess. It can make weak tasks clearer, split them, reframe them, or recommend dropping them before execution.

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

grill-plan 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 11d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vet the pending tasks in <target_repo>/autosprint/plan.md for agent-readiness — whether an implement agent could pick each one up and execute it without guessing — and sharpen the weak ones with the user.

This is the plan-level companion to grill-destination. grill-destination sharpens the destination; grill-plan sharpens the next steps toward it. It is meant to be used during the hand-review of a plan that autosprint plan just drafted — a second pair of eyes on executability, before an autosprint run executes the plan as-is.

What this skill is NOT

It does not re-plan. Generating tasks from scratch — reading the gap between the repo and destination.md and proposing what to do — is the Plan phase's job (autosprint plan). grill-plan vets and sharpens the tasks that are already in plan.md. It may sharpen, split, drop, or reframe a task, but it never invents a fresh plan. If the plan is wrong at the root (wrong tasks entirely), the fix is to re-run autosprint plan or hand-author plan.md — not this skill.

It also does not second-guess strategy. Whether a task is the right priority is the user's call and the planner's job. grill-plan asks one question per task: could an agent execute this as written?

Run it between autosprint runs, not while a loop is live — a running loop rewrites plan.md itself and would clobber your edits.

Before starting

  1. Read <target_repo>/autosprint/plan.md — the ## Pending section is the subject. Leave ## Recent completed alone.
  2. Read destination.md and adr.md for context — a task must move toward the destination and must not contradict a locked decision.
  3. Read the actual code the tasks refer to. A task's claim ("the parser silently swallows errors") must be verified against the real code — a task aimed at a problem that doesn't exist is not ready.

The rubric — is a task agent-ready?

Judge each pending task against all of these:

  • Concrete — names files, functions, or observable behavior. "Improve the code" fails; "split the 400-line run_implement in implement_phase.py" passes.
  • Scoped — one coherent piece of work. Not a mega-task spanning many files, not so trivial it's noise. The trailing (N) story-point tag must be present and sane; anything clearly above SPRINT_STORY_POINT_MAX must be split.
  • Has a done-condition — there is a way to know it is finished: a test that would pass, an observable behavior, a check. A task with no done-condition is one an agent cannot finish.
  • Self-contained — does not depend on a decision nobody has made. A decision in disguise"use uv to add numpy for the vector math" — hides the unmade decision "do we want numpy?". That is not ready: it needs deciding (and recording in adr.md), not implementing.
  • Real — the problem it describes actually exists in the current code. Verify against the code, not the task's say-so. A task may carry an explicit (unverified: <…>) tag where the planner flagged a claim it could not check — treat those as your first priority: verify the tagged claim against the code, then strip the tag once confirmed, or sharpen/drop the task if the claim is false.
  • Destination-aligned — closes distance to something in destination.md. A task that does not is orphan scope.
  • Distinct — does not overlap or duplicate another pending task.

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.

grill-plan is a skill published in the GitHub repository haakonbull/autosprint (5 stars, last pushed 2mo ago), licensed MIT. It adds 139 tokens to every session and 1,758 once invoked, about $0.0007 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 2026-08-31.
