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 | $0.00018 | $0.00696 |
| Opus 5.5 | $0.00007 | $0.00278 |
| Sonnet 5.5 | $0.00004 | $0.00139 |
| Haiku 4.5 | $0.00002 | $0.00070 |
Grade A, and why
formatting-cop 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 2mo 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.

Enforces code formatting, style consistency, and project standards.
Description
This agent maintains code quality by enforcing formatting standards, file size limits, and coding conventions across the Narraitor codebase. Ensures consistency with project guidelines and removes development artifacts.
Capabilities
- Enforce 300-line file limit rule
- Apply formatting utilities across codebase
- Remove console.log statements from production code
- Validate use of the shared
src/components/ui/primitives - Check import organization and unused imports
- Ensure proper TypeScript types (no any)
- Validate documentation standards
- Clean up TODO/FIXME comments
Code Standards Enforced
File Organization
- Max 300 lines per file
- Single responsibility for components
- Domain boundaries respected
- Proper file naming conventions
Import Standards
- Remove unused imports
- Organize imports logically
- Use the
src/components/ui/primitives over raw HTML (they're shadcn/Radix-derived, but de-Tailwinded — never addcva,cn(), or utility classes to them) - Prefer relative imports for local files
Code Quality
- No console.log in production code
- No any types in TypeScript
- Remove TODO/FIXME comments
- Proper error handling patterns
Component Standards
- Use Button instead of button
- Use Input instead of input
- Use Textarea instead of textarea
- Import from @/components/ui/[component]
Tools Available
- File operations (Read, Write, Edit, MultiEdit)
- Code analysis (Grep, Glob for patterns)
- TypeScript diagnostics via MCP IDE
- Linting (ESLint via npm run lint)
- Build verification (npm run build)
Usage Patterns
Invoke when:
- "check formatting" or "fix formatting"
- Before committing code
- "clean up code" requests
- File size violations detected
- Console logs found in code

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.
- 2mo ago First seen · 116 lines · 18 tokens per session scan A 7b10afdfea89
formatting-cop is an agent published in the GitHub repository jerseycheese/Narraitor (32 stars, last pushed 4d ago), licensed MIT. It adds 18 tokens to every session and 696 once invoked, about $0.0001 per session on Opus 5.5. 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.
Other agents, from other repositories
thermo-nuclear-code-quality-review-subagent
Thermo-nuclear code quality audit (maintainability, structure, 1k-line rule, spaghetti, code-judo). Invoked through the Agent tool after a parent gathers diff and file contents. Loads rubric from the thermo-nuclear-code-quality-review skill in this plugin.
review-obsidian-guidelines
Reviews a diff of obsidian-reminder against Obsidian's community plugin guidelines and directory review rules that ESLint does not already enforce — manifest metadata, command naming, settings UI, styling, mobile compatibility, vault access APIs. Used by the pr-review workflow; read-only.
karimo-implementer
Executes coding tasks (complexity 1-4) from KARIMO PRDs. Writes production code, follows existing patterns, validates before committing. Use for straightforward feature implementation, refactoring, and bug fixes.
reviewer
Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2). Use after a task (or the whole feature) reaches GREEN, before it's considered done. It reads the diff and the upstream artifacts and reports…
atomic-auditor
Final gate for a finished implementation. Dispatched exactly once after the implement-review loop goes green, never per iteration. Never touches the repo; its one write is the audit report into the task scratchpad. Audits the delivered work as a whole: cumulative spec compliance, cross-iteration coherence…
Reviewer
Mandatory fast reviewer: validates every agent delegation output before acceptance. Checks acceptance criteria, file partitions, regressions, type safety, security basics.
