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

dependabot-config 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.

Dependabot Configuration AI Skill Guide

Overview & Engine Architecture

Dependabot opens pull requests that bump dependency versions and alert on known vulnerabilities. Configuration lives in .github/dependabot.yml per ecosystem (npm, pip, docker, github-actions, terraform, etc.). Agents tune schedules, group related updates, ignore noisy packages deliberately, and require CI green before merge.

.github/dependabot.yml
   -> GitHub Dependabot service
       -> Version update PRs + security updates
           -> CI checks -> human/auto merge

When to use this skill

  • Enabling or retuning dependency update bots
  • Reducing PR floods with groups and schedules
  • Ignoring packages that must stay pinned
  • Aligning security updates with SCA tools like @snyk

Operational directives

  1. Commit a valid dependabot.yml under .github/.
  2. Prefer weekly schedules for apps; daily only if you can review volume.
  3. Group minor/patch updates where supported to cut PR noise.
  4. Never ignore all updates globally; ignore specific deps with reasons in comments/docs.
  5. Auto-merge only patch/minor with required status checks - never blind major auto-merge.

Tuning matrix

Problem Adjustment
Too many PRs Groups + lower limit + weekly interval
Majors break CI constantly Manual majors; group only minor/patch
Private registry fails Configure registry credentials in Dependabot secrets
Lockfile conflicts Smaller groups; rebase settings; keep CI fast

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.
