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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00083 | $0.00918 |
| Opus 5 | $0.00042 | $0.00459 |
| Sonnet 5 | $0.00017 | $0.00184 |
| Haiku 4.5 | $0.00008 | $0.00092 |
Grade A, and why
rpce-test-quality 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.

RepoPrompt CE Test Quality
Protect meaningful current contracts, not changed lines or method counts. Maximize regression signal per maintenance cost. Follow AGENTS.md and the repository harness in docs/testing.md.
Decide Before Writing
- Name the current behavior and plausible defect: user failure, data loss, protocol/security break, race, persistence error, malformed input, or costly operational failure.
- Search existing direct and outcome-level coverage.
- Define an observable oracle that distinguishes broken from fixed behavior.
- Choose the lowest layer that faithfully reproduces the risk.
- Add, consolidate, redesign, classify as diagnostics, or omit.
For a bug, prefer a test that fails against known-bad behavior. If no stable contract, credible defect, or discriminating oracle can be named, do not add a test.
Choose the Layer
- Isolated core: deterministic decisions, transformations, parsers, state machines, policy, invariants, and failure semantics.
- Provider package: provider protocol, codec, translation, launch arguments, and model mapping under
Packages/RepoPromptAgentProviders/Tests. - Root SwiftPM: module behavior without a GUI, including actors, persistence, fixtures, subprocess adapters, in-process MCP, and deterministic concurrency under
Tests/RepoPromptTests. - Runtime diagnostics: assembled-app-only rendering, restoration, routing instrumentation, churn, or resource investigations. Require a bounded scenario, privacy-safe machine-readable evidence, entry point, and cleanup path. Without an acceptance threshold, a benchmark is diagnostics.
- Live/packaged smoke: real app/MCP wiring, bundle layout, embedded helpers, ownership, signing, provenance, and a few critical journeys.
- Structural guard: last resort when executable behavior, compiler boundaries, lint, or guardrails cannot cheaply enforce a narrow constraint.
Do not use smoke as the only protection for deterministic logic.
Quality Gate
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

rpce-test-quality is a skill published in the GitHub repository repoprompt/repoprompt-ce (921 stars, last pushed today), licensed Apache-2.0. It adds 83 tokens to every session and 918 once invoked, about $0.0004 per session on Opus 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 2026-08-30.
