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 | $0.00042 | $0.00295 |
| Opus 5 | $0.00021 | $0.00148 |
| Sonnet 5 | $0.00008 | $0.00059 |
| Haiku 4.5 | $0.00004 | $0.00030 |
Grade A, and why
cli-control 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 yesterday.
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
CLI Control
Gather reproducible evidence from terminal-hosted interfaces without changing production behavior.
Workflow
- Identify the command, working directory, terminal conditions, and observable contract.
- Choose the smallest repeatable method: direct execution or repository tests for ordinary output and status; a terminal-capable harness for prompts, signals, resizing, hangs, or restoration.
- Prefer an existing trusted harness. Otherwise use a temporary local harness outside the repository without adding dependencies.
- Drive one action at a time and capture the smallest transcript or measurement that proves or disproves the behavior.
- Check interrupts, cleanup, exit status, hangs, and terminal restoration only where relevant.
- Clean up only sessions, processes, and artifacts created by this workflow.
Keep verification read-only unless the parent task separately authorizes implementation. Use behavior-implement and test-design for fixes or regression tests. Leave browser, desktop, Electron, and other graphical surfaces to ui-control.
Do not send credentials or destructive commands, retain sensitive transcripts, or keep one-off harness code in the repository without a product-test consumer.
Finish with the command and conditions, observed output and exit status, evidence, and any blocker or limitation.
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.

cli-control is a skill published in the GitHub repository yarlson/yarstack (3 stars, last pushed 4d ago), licensed MIT. It adds 42 tokens to every session and 295 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 2026-08-31.

verify-regression-tests
Verify that a regression test actually detects the defect it claims to guard against. Use after adding or reviewing a bug-fix guard, reproducing the original failure after a fix, or investigating a suspiciously green regression test. Do not use for general TDD, broad test-suite audits, mutation-score optimization…
repository-bootstrap
Audit and establish or upgrade the canonical repository governance baseline. Use only when explicitly asked to bootstrap, standardize, or upgrade a repository; do not use for feature development or source-code restructuring.
repository-hygiene
Perform a read-only evidence-based audit of stale docs, agent files, scripts, generated artifacts, duplicate code, and optional tools. Use only when explicitly asked for cleanup or governance review; do not delete or refactor during the audit.
