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 | $0.00427 | $0.00427 |
| Opus 5.5 | $0.00171 | $0.00171 |
| Sonnet 5.5 | $0.00085 | $0.00085 |
| Haiku 4.5 | $0.00043 | $0.00043 |
Grade A, and why
pudo-code-system copilot-instructions.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
GitHub Copilot Instructions
This repository is an AI engineering methodology and prompt/skill pack. Treat changes as documentation, workflow, and agent-instruction changes unless the task explicitly says otherwise.
PUDO Workflow
Use the PUDO loop for non-trivial work:
- Plan: define goal, scope, constraints, success criteria, and non-goals.
- Understand: inspect relevant files and existing patterns before editing.
- Develop: make small, focused patches that stay within scope.
- Optimize: self-review, run relevant checks, and summarize risks.
Use quality gates before handoff:
quality/quality-gates.mdquality/qc-checklists.mdquality/ai-output-review.mdquality/edge-cases/general.md
Repository Shape

AGENTS.md,codex/,claude/,cursor/,opencode/,antigravity/,kiro/, and.github/.
Editing Rules
- Prefer Markdown changes that are concise, scannable, and consistent with nearby files.
- Do not rename or restructure directories unless the task requires it.
- Do not update model names or tool-specific claims unless they are verified from current docs.
- Keep legacy compatibility notes when adding newer agent config formats.
- Avoid invented commands, unsupported config keys, and broken links.
- Preserve translations unless the task explicitly asks to update them.
Verification
For docs-only changes, run the cheapest relevant checks:
git diff --check- targeted
Test-Pathchecks for new internal links - targeted
rgsearches for stale paths or deprecated wording
If checks are skipped, state why.
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.
