What it costs to keep this loaded
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 | $0.00064 | $0.00221 |
| Opus 5.5 | $0.00026 | $0.00088 |
| Sonnet 5.5 | $0.00013 | $0.00044 |
| Haiku 4.5 | $0.00006 | $0.00022 |
Grade A, and why
coding-guidelines 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 10d 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
Coding Guidelines
CODING_GUIDELINES.md at the repository root is normative for every change. Read
it before writing code, and cite its sections when reviewing — do not paraphrase it here.
Before committing, pushing or opening a PR, run the tomtom-mcp-preflight skill: it runs the CI gates and audits
the diff against those guidelines. To review a branch or pull request, run the tomtom-mcp-review skill. To
bring the docs portal's MCP pages in line with the server, run the tomtom-mcp-docs-update-pr skill;
for public copy, apply the tomtom-mcp-tov skill.
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.

coding-guidelines is a skill published in the GitHub repository tomtom-international/tomtom-maps-mcp (59 stars, last pushed yesterday), licensed Apache-2.0. It adds 64 tokens to every session and 221 once invoked, about $0.0003 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.
