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

defi-native-skill AGENTS.md 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 8d 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md: how to work on this repo (any agent, any harness)

defi-native is a public Agent Skill (SKILL.md + references/) plus its marketing site (site/, deployed to https://defi-native.ai by GitHub Pages on every push to main). This file is the operating manual for any coding agent. CONTRIBUTING.md covers content rules for the skill body; MAINTENANCE.md covers the upkeep policy.

Hard conventions, every edit, no exceptions

  • Never use em or en dashes. Commas, colons, periods, parentheses.
  • Expand every acronym at first use per file.
  • Every number carries an as-of date or is labeled a calibration example.
  • Never invent a metric, count, or quote. Verify before writing.
  • SKILL.md stays lean; knowledge lives in references/ and loads per task.
  • The skill is read-only by design: it never constructs, signs, submits, or approves transactions. Do not weaken that language anywhere.

Versioning (MAINTENANCE.md is canonical)

Patch = calibration refresh. Minor = new section or reference file. Major = structural change to directives or workflow. Every release gets a CHANGELOG.md entry, and the site changelog gets a plain-language entry.

Gates: run these before any push

python3 scripts/verify_manifest.py --skip-network   # skill invariants, counts, caps
python3 scripts/build_site.py                       # site must match the skill

Both must exit 0. CI runs them on every PR (.github/workflows/pr-check.yml) and the Pages deploy refuses drifted pages. What build_site.py enforces: stat tiles match manifest/api-routes/glossary/evals counts, version strings match SKILL.md on both pages, the update page offers the current version, every must or core priority manifest source is named in the data-sources list, and asset URLs carry current content hashes.

Editing the site

  • Pages: site/index.html and site/update/index.html. Shared styles and script: site/assets/site.css and site/assets/site.js.
  • After ANY change to site/assets/site.css or site.js run python3 scripts/build_site.py --stamp to refresh the cache-busting hashes on both pages, then the gate. Skipping this fails the deploy.
  • Source logos for the marquee live in site/assets/logos/.
  • The GitHub star count is fetched live client side; the number in the HTML is only a no-JS fallback.

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.
