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 | $0.00325 | $0.00325 |
| Opus 5.5 | $0.00130 | $0.00130 |
| Sonnet 5.5 | $0.00065 | $0.00065 |
| Haiku 4.5 | $0.00032 | $0.00032 |
Grade A, and why
codemap 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
codemap
This repository holds a skill for turning a codebase into an explorable isometric diagram. The full instructions are in SKILL.md — read that file and follow it when asked to map, diagram or visually explain how a system fits together.
Two things worth knowing before you start:
The drawing is already done. assets/template.html is a complete,
self-contained page — isometric projection, panning, zooming, animation and the
side panel all work. Building a map means replacing four data arrays,
STATS, NODES, EDGES and REGIONS, plus the <title> and the
<svg aria-label>. REGIONS draws a dashed outline around the parts of the
system the repository does not own, and may be left empty.
The facts are the work. A diagram of boxes labelled Service, Database and API tells a reader nothing the directory listing would not have. Mine the repository for measured numbers, platform limits worked around, and comments explaining why a constant is what it is, and put real values on the edges.
Verify and render before handing anything over:
python3 scripts/verify.py my-map.html
python3 scripts/render.py my-map.html render.png
Look at the PNG. Several faults that matter — an empty panel from a bad default selection, labels clipped by the blocks in front of them — pass every static check and are obvious the moment the page is rendered.
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.
