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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00557 |
| Opus 5.5 | $0.00000 | $0.00223 |
| Sonnet 5.5 | $0.00000 | $0.00111 |
| Haiku 4.5 | $0.00000 | $0.00056 |
Grade A, and why
prp-base-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 2mo 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.

Execute BASE PRP
PRP File: $ARGUMENTS
Mission: One-Pass Implementation Success
PRPs enable working code on the first attempt through:
- Context Completeness: Everything needed, nothing guessed
- Progressive Validation: 4-level gates catch errors early
- Pattern Consistency: Follow existing codebase approaches
- Read PRPs/README.md to understand PRP concepts
Your Goal: Transform the PRP into working code that passes all validation gates.
Execution Process
-
Load PRP
- Read the specified PRP file completely
- Absorb all context, patterns, requirements and gather codebase intelligence
- Use the provided documentation references and file patterns, consume the right documentation before the appropriate todo/task
- Trust the PRP's context and guidance - it's designed for one-pass success
- If needed do additional codebase exploration and research as needed
-
ULTRATHINK & Plan
- Create comprehensive implementation plan following the PRP's task order
- Break down into clear todos using TodoWrite tool
- Use subagents for parallel work when beneficial (always create prp inspired prompts for subagents when used)
- Follow the patterns referenced in the PRP
- Use specific file paths, class names, and method signatures from PRP context
- Never guess - always verify the codebase patterns and examples referenced in the PRP yourself
-
Execute Implementation
- Follow the PRP's Implementation Tasks sequence, add more detail as needed, especially when using subagents
- Use the patterns and examples referenced in the PRP
- Create files in locations specified by the desired codebase tree
- Apply naming conventions from the task specifications and CLAUDE.md
-
Progressive Validation
Execute the level validation system from the PRP:
- Level 1: Run syntax & style validation commands from PRP
- Level 2: Execute unit test validation from PRP
- Level 3: Run integration testing commands from PRP
- Level 4: Execute specified validation from PRP
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.

prp-base-execute is a command published in the GitHub repository mort-lab/excel-mcp (5 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 557 tokens. 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.
