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 | $0.00224 | $0.00224 |
| Opus 5.5 | $0.00090 | $0.00090 |
| Sonnet 5.5 | $0.00045 | $0.00045 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
tale 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 2mo 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
Tale — Copilot instructions
The canonical contract for working in this repository is AGENTS.md at the repo
root — the shared tale-project contract — followed by .agents/repo.md, the
repo-specific contract (layout, domain rules, skills index, debt ledger). Read both and follow
them.
Non-negotiable reflexes (full rules in the two contracts):
- Reuse before you write — search
packages/ui, then sharedapp//lib/, then the feature; extend existing primitives, never fork them. - A change is rarely one file — translations in all base locales, docs with code, a migration for any data-model change, WCAG 2.1 AA for UI, and a test for every change.
- Verify by observing the real outcome, not by inspection. Never claim a success you haven't seen.
- Think before acting — classify the task, weigh impact, prefer the smallest correct, most reversible change.
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.
