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 | $0.00303 | $0.00303 |
| Opus 5.5 | $0.00121 | $0.00121 |
| Sonnet 5.5 | $0.00061 | $0.00061 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
apex-accelerator json.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 6d 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
JSON Guidelines
Repository-specific JSON and JSONC rules. Prettier formats .json/.jsonc (2-space
indent, LF, final newline); run it rather than hand-formatting. .json files never
contain comments or trailing commas.
JSONC (JSON with Comments)
Files like .mcp.json, devcontainer.json, and .markdownlint-cli2.jsonc
use JSONC format:
- Use
//for single-line comments explaining non-obvious configuration - Group related settings with section comments
- Do not use
/* */block comments
Key Ordering
Preserve the existing order and insert keys beside their logical neighbors. Group package metadata, scripts and dependencies separately; keep container build, lifecycle, environment and customization settings together. Group MCP servers by transport type. The current manifest is authoritative; do not reorder an entire file to satisfy a stale exhaustive key list.
Governance Constraint Files
04-governance-constraints.json in agent-output/ is generated by the
apex-azure-governance-discovery skill's discover.py; its fields are defined in the
skill's schema reference.
Do not edit it manually — regenerate it through the governance discovery workflow.
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.

apex-accelerator json.instructions.md is an instructions file published in the GitHub repository jonathan-vella/apex-accelerator (50 stars, last pushed yesterday), licensed MIT. It adds 303 tokens to every session, about $0.0012 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.
