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 | $0.01270 | $0.01270 |
| Opus 5.5 | $0.00508 | $0.00508 |
| Sonnet 5.5 | $0.00254 | $0.00254 |
| Haiku 4.5 | $0.00127 | $0.00127 |
Grade A, and why
Agent Naming Conventions 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.

Agent Naming Conventions for copilot-kit
These conventions ensure agents from this repository are instantly identifiable when mixed with project-specific agents in the VS Code agent picker.
Naming Pattern
All agents in this repository must follow:
kit-{category}-{role}(-{qualifier})*
| Segment | Purpose | Examples |
|---|---|---|
kit- |
Origin prefix — identifies the agent as coming from copilot-kit |
Always kit- |
{category} |
Domain grouping | copilot, sdd, backend |
{role} |
The persona or role the agent fulfills | architect, expert, engineer |
(-{qualifier})* |
Optional qualifier for specificity | -senior, -planner |
Why kit-?
ck-— too cryptic, not recognizable at a glancecopilot-kit-— too long, wastes space in the agent pickerkit-— 4 chars, groups all copilot-kit agents together when browsing
Agent naming is role-oriented, not action-oriented
Skills use kit-{category}-{verb}-{object} because they perform actions.
Agents use kit-{category}-{role} because they represent personas with expertise, tools, and behavioral guidelines.
Categories
| Category | Scope |
|---|---|
copilot |
Agents related to Copilot customization and configuration workflows |
sdd |
Agents related to Spec-Driven Development workflows |
backend |
Agents focused on backend / server-side engineering |
New categories follow the same pattern: short, lowercase, hyphenated. A category can be domain-specific (e.g., frontend, devops) or workflow-specific (e.g., sdd, copilot).
Filename Convention
The filename must follow:
{agent-name}.agent.md
Where {agent-name} matches the naming pattern. All agents live directly in .github/agents/ (flat structure, no subdirectories):
.github/agents/
kit-copilot-engineering-team.agent.md
kit-sdd-expert.agent.md
kit-backend-engineer.agent.md

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.
