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 | $0.01544 | $0.01544 |
| Opus 5 | $0.00772 | $0.00772 |
| Sonnet 5 | $0.00309 | $0.00309 |
| Haiku 4.5 | $0.00154 | $0.00154 |
Grade A, and why
code-copilot-team opus-4-7-features.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 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.
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.

Opus 4.7 Features & Optimization
Optional guidance for sessions using Claude Opus 4.7 (v2.1.111+). Load this rule when you want to leverage Opus 4.7-specific capabilities.
Adaptive Thinking (Breaking Change)
Opus 4.7 changes the API contract for extended thinking. The legacy form is rejected:
thinking: {type: "enabled", budget_tokens: N}→ returns 400 Bad Request on Opus 4.7.- Only
thinking: {type: "adaptive"}is accepted.
With adaptive thinking, the model dynamically decides when and how much to think based on query complexity. There is no fixed token budget — Claude self-regulates depth.
How to control depth:
- Use the
effortparameter (xhigh/high/medium/low) instead ofbudget_tokens. - Thinking is also promptable in-message:
- "Think carefully and step-by-step" → encourages deeper reasoning.
- "Prioritize responding quickly" → encourages a shorter thinking pass.
Older models: enabled/budget_tokens is deprecated on Opus 4.6 and Sonnet 4.6 (still functional today, but on the way out). Migrate to adaptive proactively so your code keeps working when the deprecation lands.
Effort Level: xhigh
Opus 4.7 introduces a new effort level xhigh between high and max. Other models fall back to high when xhigh is requested.
| Effort | When to use | Phase fit |
|---|---|---|
low |
Quick lookups, file searches, trivial edits | — |
medium |
Standard implementation, build tasks | Build |
high |
Architecture, planning, detailed review | Research, Plan, Review |
xhigh |
Complex multi-file reasoning, deep architectural analysis, hard debugging | Plan (large features), Review (cross-cutting PRs) |
Availability: xhigh became selectable in Claude Code v2.1.111+ when running Opus 4.7.
Default change: From Claude Code v2.1.117+, xhigh is the default effort level for Opus 4.7. On v2.1.111–v2.1.116 the default is still high and you must opt in with /effort xhigh. Other models continue to default to high regardless of Claude Code version.
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.

code-copilot-team opus-4-7-features.instructions.md is an instructions file published in the GitHub repository gosha70/code-copilot-team (6 stars, last pushed yesterday), licensed MIT. It adds 1,544 tokens to every session, about $0.0077 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
