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 | $0.00046 | $0.01690 |
| Opus 5 | $0.00023 | $0.00845 |
| Sonnet 5 | $0.00009 | $0.00338 |
| Haiku 4.5 | $0.00005 | $0.00169 |
Grade A, and why
verify 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 192 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Adversarial Verification
Three agents with competing incentives: one finds issues, one disproves them, one judges.
Standalone Codex
Skip the Claude marker below. Create each fresh panelist with spawn_agent,
deliver context while it runs with send_message, trigger another turn once it
is idle with followup_task, wait with wait_agent, and stop its current turn
with interrupt_agent only when necessary. Never spawn codex-verifier and
never run codex-run.ts from inside Codex.
Only read-only reviewers may overlap. Writers share the working tree unless the live host explicitly offers isolation, so any implementer and test-writer follow-up must use non-overlapping ownership and run serially.
Claude-only marker: standalone Codex must skip this command.

When to Use
- Security-sensitive code (auth, crypto, permissions)
- Data integrity (migrations, schema changes, ETL)
- Financial logic (payments, billing, calculations)
- Breaking changes (API contracts, public interfaces)
The Three-Agent Pattern
Agent 1: Finder
Agent(reviewer, "You are a bug finder. Analyze the following code/changes thoroughly.
Score yourself: +1 for low-impact issues, +5 for medium-impact, +10 for critical.
Report every potential issue you find — edge cases, race conditions, missing validation,
security holes, logic errors, performance problems.
Report your total score at the end.
Target: [describe what to verify]
Files: [list files]")
Finder over-reports by design — this is the superset of all possible issues.
Standalone Codex panel
Use three separate native agents instead of the Claude bridge: spawn a fresh issue-finder, wait until it finishes, pass its report to a separate disprover, then wait until that agent finishes before spawning the judge with both reports. Follow the lifecycle above for each role. Skip the Claude cross-model finder below.
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.

verify is a skill published in the GitHub repository darkroomengineering/cc-settings (42 stars, last pushed 4d ago), licensed MIT. It adds 46 tokens to every session and 1,690 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 2026-08-30.

dotfiles-bootstrap
Bootstrap a workstation with the dotfiles framework. Takes a GitHub user / owner+repo / explicit clone URL and runs dot init (which shells out to chezmoi) with the right safety prompts. Honors the active agent profile (ask / plan / apply / audit) so it defaults to dry-run in safer modes and full apply in apply.
astro-dso-doc
Generates a complete, polished HTML documentation page, a processing checklist, an AstroBin post JSON, a PixInsight process icon set (XPSM), AND a ready-to-paste PixInsight project Description field for a deep-sky object (DSO) astrophotography project. Use this skill whenever the user mentions astrophotography, a DSO…
document-code
Apply Google Style documentation standards to Python, Go, TypeScript, and Terraform code. Use when writing or reviewing code that needs docstrings/comments/JSDoc, when asked to "document this code", "add docstrings", "follow Google Style", or when improving code documentation quality. Supports Python docstrings, Go…
work-on-ticket
Fetches Jira ticket details, creates an appropriately named branch, and initiates the task planning workflow. Use when the user says "work on [TICKETID]" or similar phrases.
datadog
Use this skill when you need to search Datadog logs, query metrics, tail logs in real-time, trace distributed requests, investigate errors, compare time periods, find log patterns, check service health, or export observability data.
document-project
Generate comprehensive, professional project documentation structures including README, ARCHITECTURE, USERGUIDE, DEVELOPERGUIDE, and CONTRIBUTING files. Use when the user requests project documentation creation, asks to "document a project", needs standard documentation files, or wants to set up docs for a new…
