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
AgentX 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 12d 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
Global Copilot Instructions
Frontier Corp is the canonical product and agent identity. AGENTS.md holds the
shared contract (quality loop, gates, classification, commits). This file adds
only Copilot-specific guidance and stays small because it loads on every request.
Paths below are plain text: read them when a task needs them.
Before Editing
Apply the runtime transport and guided interaction rules in AGENTS.md; do not
initialize a repository merely to satisfy a command-path example.
For covered work (AGENTS.md applicability), run
.frontier/runtime/frontier.ps1 loop start -p "<task>" before the first covered
mutation and finish with loop complete after an independent reviewer approves the final
state (--verdict approved --reviewer <id> --high 0 --medium 0).
Honesty rule: report gate state from loop status and real artifacts; do not
refresh old evidence or invent scores. Details: .github/AGENT-PROTOCOL.md
(relative to this file).
Loading Context
- Read the spec, skill or instruction that governs the task before generating; repository conventions override general knowledge. Skip that for plain questions and research.
- Language instructions load automatically by file pattern. For other file types,
pick the matching skill from
Skills.md(Terraform, Bicep, Blazor, SQL, YAML pipelines, API design, UX) instead of loading the whole index. - Load only the active phase's skills; prefer
grep/readof the exact section over whole-file reads.
Conventions
- ASCII only (U+0000-U+007F):
[PASS]/[FAIL],->, plain-. - Directive language follows RFC 2119 (MUST, SHOULD, MAY).
- Validate agent, skill and instruction frontmatter with
pwsh scripts/validate-frontmatter.ps1.
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.
