In plain words
What is it for?
Use it when working on mdingest, including its Medium, Dev.to, and Substack page-ingestion features.

Token cost

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.

Security

Grade A, and why

mdingest AGENTS.md scanned grade A with 1 finding 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 590 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — mdingest Operating Contract

API that ingests blog/article/newsletter pages to clean Markdown for LLM consumption. Currently supports Medium (via Freedium), Dev.to (via Forem API), and Substack (free posts via public API + HTML→Markdown). Designed for future providers.

Operating contract for any AI agent (Devin, Claude Code, Cursor) working on this repo. Read this file before writing code.

Communication style

  1. Lead with the next action. First line is something the reader can do.
  2. Number multi-step tasks. Each step is one bounded action.
  3. End with one concrete next step.
  4. Suppress tangents. Finish the first issue, then offer the second.
  5. Restate state every turn. One-line status before the new action.
  6. Specific time estimates. "About 15 minutes if tests cover this" — not "a bit".
  7. Make wins visible. When something works, say so with evidence.
  8. Matter-of-fact errors. State cause and fix. No "Uh oh" or "Oh no".
  9. Cap lists at 5 items. Group into sub-lists or split into steps if longer.
  10. No preamble, no recap, no closers.

Code style

  • Named exports only. No default exports. Greppable, explicit imports.
  • Short files. One responsibility per file. If a file exceeds ~150 lines, split it.
  • Tables over paragraphs in docs and comments. Scannable, not readable.
  • Flat folder structure. Max 2 levels deep under src/.
  • File names say what's inside. freedium.service.ts fetches from Freedium. No utils.ts.
  • No walls of text in comments. If a comment exceeds 3 lines, it's a doc — move it to docs/.
  • Functional style: pure functions where possible, no classes except NestJS modules/services/controllers.
  • Use TypeScript features: type narrowing, discriminated unions, satisfies, as const.

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.
