Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00034 | $0.00350 |
| Opus 5 | $0.00017 | $0.00175 |
| Sonnet 5 | $0.00007 | $0.00070 |
| Haiku 4.5 | $0.00003 | $0.00035 |
Grade A, and why
feature-rpi 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
Feature RPI
Use this skill for medium and large changes.
Start
Open these first:
README.mddocs/TECH_STACK.mddocs/RPI_METHODOLOGY.mdAGENTS.md- one or more of:
docs/AGENT_ARCHITECTURE.mddocs/ANTI_HALLUCINATION_SOP.mddocs/PHASE_REGISTRY.mddocs/algorithms.md
Research
- identify the real execution path before editing
- inspect affected interfaces, neighboring modules, and verification points
- capture file paths, constraints, and open risks
- keep reading focused; do not preload unrelated subsystems
Plan
- produce a short numbered plan before editing
- name touched files or areas
- define acceptance criteria and verification commands
- run the
gap-checkskill if the change affects architecture, scoring, safety, or orchestration
Implement
- make the smallest coherent multi-file change set
- preserve separation of concerns from
AGENTS.md - keep files under the 200-line guideline
- verify iteratively instead of waiting until the end
Verification
- run focused tests or lint/typecheck commands for the touched surface
- if full verification is not possible, state what was or was not run
Stop And Rescope When
- the task crosses into an unexpected subsystem
- the plan assumptions no longer hold
- context is approaching the dumb zone
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.

feature-rpi is a skill published in the GitHub repository matheusht/redthread (47 stars, last pushed 13d ago), licensed MIT. It adds 34 tokens to every session and 350 once invoked, about $0.0002 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 2026-09-01.
