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 | $0.00008 | $0.00343 |
| Opus 5.5 | $0.00003 | $0.00137 |
| Sonnet 5.5 | $0.00002 | $0.00069 |
| Haiku 4.5 | $0.00001 | $0.00034 |
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 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.
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
Files Changed:
git diff --stat
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-core-execute is a command published in the GitHub repository mort-lab/excel-mcp (5 stars, last pushed 2mo ago), licensed MIT. It adds 8 tokens to every session and 343 once invoked, about $0.0000 per session on Opus 5.5. 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.
