prp-core-execute

prp-core-execute is a command for Claude Code from mort-lab/excel-mcp. It costs 8 tokens per session (343 once invoked), scanned A, original, MIT.

A command that carries out a feature PRP, meaning a written implementation plan with ordered tasks and acceptance checks, until the plan is complete. It validates each task and then runs the full validation suite.

In plain words
What is it for?
Use it with a PRP file to implement the listed feature, track tasks, run linting, type checks, and tests, and move the completed plan into a completed folder.
Why use it?
It keeps a multi-step feature implementation moving through its planned tasks and checks, fixing failed validations before continuing.

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

prp-core-execute 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 3d 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.

What it actually says

Execute Feature PRP

PRP File: $ARGUMENTS

Instructions

  • Ingest the PRP file completely
  • Think hard about the implementation approach
  • Execute every task in the STEP-BY-STEP TASKS section sequentially
  • Validate after each task using the task's validation command
  • If validation fails, fix and re-validate before proceeding
  • Run full validation suite from the PRP when all tasks complete
  • Critical: Don't stop until the entire plan is fulfilled and all validation passes
  • Use TodoWrite to track progress through tasks
  • Trust the PRP's strategic direction, but verify tactical details (imports, paths, names)
  • If the PRP has errors in details, fix them and note in report

Success Criteria

  • ✓ Every task completed
  • ✓ All validation commands pass
  • ✓ Acceptance criteria met

Completion

Once all validation passes:

mkdir -p .claude/PRPs/features/completed
mv .claude/PRPs/features/{prp-file}.md .claude/PRPs/features/completed/

Report

After completion:

Summary:

  • Feature: {name}
  • Tasks completed: {count}
  • Files created/modified: {list}

Validation:

✓ Linting: Passed
✓ Type checking: Passed
✓ Tests: X/X passed

Adjustments (if any):

  • Note any PRP details that were incorrect and how you fixed them

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.
