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

p6-func-regression 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 today.

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.

/p6-func-regression – Run Regression Tests

Ensures that existing functionality has not been broken by new changes.

Argument: $ARGUMENTS = [area/sprint]

If provided: Focus regression on the specified area. If not provided: Test all areas affected by the latest changes.

Prerequisites

  • Existing automated tests present
  • SPRINT.md with latest changes

Agent

  • Type: qa-tester
  • Model: sonnet

Context (Orchestrator prepares)

Orchestrator reads in advance and delivers inline:

  • From SPRINT.md: Which features/modules were changed most recently
  • From tests/: Existing test files (file names + test case overview only)

Prompt Template

Goal: Run regression tests – check whether recent changes have broken existing functionality

Recent Changes: [inline from SPRINT.md]

Output Format:

# Test Area Total Tests Passed Failed Regressions

New regressions (if any):

# Regression Affected Feature Suspected Cause

Constraints:

  • Run existing tests ONLY, do not write new ones
  • Focus on areas affected by recent changes
  • Assign each regression clearly to a change

Orchestrator Checkpoint

  • All existing tests executed?
  • Regressions clearly documented and assigned?

Write Detail File

Write the result to docs/quality/func_regression.md (overwrite). Frontmatter:

---
phase: P6
subskill: func-regression
status: active
last_updated: <DD.MM.YYYY>
---

Body sections: ## Scope, ## Test Results (table), ## Regressions Detected.

Update Sub-Index

Update docs/quality/FUNCTIONAL.md:

  • Set **Last Updated:** <DD.MM.YYYY>.
  • In its Detail Files table: ensure a row for [func_regression.md](func_regression.md) with status complete.
  • Lift any newly detected regression into Open Risks with assignment.

Handover Epilogue

Before writing. docs/HANDOVER.md is capped — the file states its own limit in its header (default: ≤5 KB / ~150 lines). Two rules follow from that, and neither is optional:

  • Replace this command's previous epilogue block, do not append a second one. Stacking is what pushes the file over; one skill run has been measured adding 1021 B, ~20 % of the cap.
  • If the file is already near its cap, shorten before you add. Reading the cap sentence is not the same as measuring: check the actual size, and when there is no room, condense existing content or hand the user /cleanup instead of growing the file further.

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.

p6-func-regression is a command published in the GitHub repository jonase47/ccpr (1 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 795 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 2026-09-03.
