mav-plan-execution

mav-plan-execution is a skill for Claude Code from thermiteau/maverick. It costs 66 tokens per session (1,269 once invoked), scanned A, original, Apache-2.0.

A step-by-step process for carrying out an implementation plan, with checks after each step. It also tracks progress and defines how to handle failures or lost sessions.

In plain words
What is it for?
Use it to implement issue tasks in order, verify each result, recover progress after a crash, and stop or escalate when a problem persists.
Why use it?
It prevents coding work from moving ahead without verification and limits repeated unsuccessful fixes. The process can pause for human checkpoints or continue autonomously.

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

mav-plan-execution 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 8d 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plan Execution

Execute an implementation plan step-by-step. Each step is implemented, verified, and committed before moving to the next. Progress is tracked durably on GitHub so it survives session loss.

Execution Mode

  • Solo mode (called from do-issue-solo): work autonomously. Only pause when genuinely blocked or when the issue is ambiguous. Press through recoverable problems.
  • Guided mode (called from do-issue-guided): provide checkpoints to the user. Pause when uncertain, report progress at natural break points.

Retry Budget (canonical)

Two fix attempts, then mav-systematic-debugging, then escalate per mode. This is the single retry budget for implementation work — other skills reference this rule rather than defining their own. If the same fix fails twice, the diagnosis is wrong: step back and think differently, never retry the same change a third time.

Execution Loop

1. Load the Tasks

Read the task list from one of:

  • The tasks comment on the GitHub issue (if working from do-issue)
  • The task list directly (if invoked standalone)
# The tasks comment id lives in the task-progress marker
uv run maverick task-progress read <repo> <issue>   # -> .comments.tasks
gh api "repos/<repo>/issues/comments/<id>" --jq '.body'

2. Check for Prior Progress

If resuming after a crash or new session:

  • Parse the checkboxes in the tasks comment (- [x] = done, - [ ] = pending)
  • Cross-reference with git log — if commits exist for tasks that aren't checked off, the comment update was lost. Check them off now (step 3.6).
  • Resume from the first genuinely unchecked task.

3. Execute Each Task

For each task in the list:

  1. Mark in-progress — note which task you are working on
  2. Implement — make the change described in the task
  3. Verify — run verification (lint, typecheck, tests) per the mav-local-verification skill
  4. Fix if needed — apply the retry budget above
  5. Commit — descriptive message referencing the issue number, using conventional commits
  6. Mark complete — check the task off durably:
    uv run maverick tasks check <repo> <issue> <n>
    
    The command is idempotent, edits exactly one checkbox, and goes through the App identity when configured. Never PATCH the comment body by hand.

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.
