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 | $0.00853 | $0.00853 |
| Opus 5.5 | $0.00341 | $0.00341 |
| Sonnet 5.5 | $0.00171 | $0.00171 |
| Haiku 4.5 | $0.00085 | $0.00085 |
Grade A, and why
zeph 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.
How it starts
The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Copilot Code Review Instructions
Project Context
Zeph is a Rust AI agent workspace (Edition 2024, resolver 3) with 31 library crates under crates/ plus the zeph CLI binary. Review all changes against these standards.
Architecture Rules
zeph-coreorchestrates all leaf crates; no reverse dependencies allowedzeph-agent-context,zeph-agent-persistence, andzeph-agent-toolsMUST NOT depend onzeph-core— the dependency runszeph-core→ these crates, never the reverse; flag any newzeph-coreimport added to themzeph-durableis a Layer-0 infra crate (alongsidezeph-db,zeph-common); it MUST NOT depend onzeph-llm,zeph-memory,zeph-core,zeph-sanitizer, or any business-layer cratezeph-tui,zeph-a2a,zeph-acp,zeph-gateway,zeph-scheduler, andzeph-benchare feature-gated and optional- All dependencies defined in root
[workspace.dependencies]with no features at workspace level - Crates inherit via
workspace = trueand specify features locally - TLS:
rustlsonly — reject anyopenssl-sysintroduction - Dependencies must be sorted alphabetically in Cargo.toml
Rust Code Standards
- Edition 2024 native async traits — reject
async-traitcrate usage unsafecode is not allowed — if you see anyunsafeblock, treat it as a blocking issue and call it out explicitly- Avoid
.unwrap()and.expect()in non-test code — prefer?with error propagation - Library crates use

tracingcrate only — rejectlogcrate orprintln!in library code - Builder methods must return

impl Into<String> - Feature-gated modules:
#[cfg(feature = "name")]onpub modinlib.rs - Formatting: use rustfmt’s default settings (no project-specific rustfmt.toml)
Security Review (Critical)
- Flag hardcoded secrets, API keys, tokens, or credentials
- Flag SQL injection risks in SQLite queries (must use parameterized queries)
- Flag command injection in shell executor (validate and sanitize inputs)
- Flag path traversal in skill loader and file operations
- Flag missing input validation at system boundaries
- Flag XSS in any user-facing output
- Verify

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.

zeph copilot-instructions.md is an instructions file published in the GitHub repository bug-ops/zeph (65 stars, last pushed 5d ago), licensed MIT. It adds 853 tokens to every session, about $0.0034 per session on Opus 5.5. 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 2026-08-30.
