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

ai-native-sdlc 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 1mo 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.

What it actually says

AGENTS.md

This repo is a reusable skill and plugin bundle implementing the AI-native SDLC workflow. Follow these conventions when working in it.

Source of truth

  • The workflow lives in skills/ai-native-sdlc/SKILL.md. Read it first, then the references it routes to (references/playbook.md, references/adoption.md).
  • Templates in skills/ai-native-sdlc/assets/ are copied into target projects — never edited to fit one project.
  • skills/ai-native-sdlc/scripts/init_workflow.py performs that copy; change the script when the scaffold layout changes.
  • skills/ai-native-sdlc/scripts/init_org.py scaffolds the optional agent org (roles, protocol, intake); change it when the org templates change.

Validation

After changing the skill or plugin, run the self-check suite (from the repo root):

python3 skills/ai-native-sdlc/scripts/quick_validate.py skills/ai-native-sdlc
bash tests/test_gate.sh
bash tests/test_init.sh
python3 -m unittest discover -s tests -v

All must pass before finishing; CI runs the same checks (.github/workflows/self-check.yml). Keep plugin.json and SKILL.md consistent in name, description, and version — quick_validate.py enforces this.

Conventions

  • Keep SKILL.md short; put phase detail in references.
  • Keep artifacts (intent/spec/plan templates) generic; org specifics belong in the adopter's own skills and hooks.
  • Never add hooks or secrets for a specific adopter into the shared templates.
  • Commit with the repo-local git identity (bashebr <[email protected]>); never fall back to the global git identity.
Changes

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.
