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 | $0.00144 | $0.01577 |
| Opus 5.5 | $0.00058 | $0.00631 |
| Sonnet 5.5 | $0.00029 | $0.00315 |
| Haiku 4.5 | $0.00014 | $0.00158 |
Grade A, and why
tc-read-project 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.
How it starts
The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Reading TwinCAT projects through TcKit
First-touch orientation belongs to tc-orient-project. This skill picks up once orientation is done and the user asks for something specific.
Always read in layers. Never fetch a full POU when one method suffices.
Tool selection — read this before calling anything
This skill uses only the TcKit reader tools and the stock Read/Grep/Glob. The reader tools are:
mcp__tckit__GetStructure— project map (POUs, GVLs, DUTs, tasks, libraries)mcp__tckit__GetPouInterface— declarations and method signatures for one POUmcp__tckit__GetPouItem— declaration + body for one method, action, or property accessormcp__tckit__GetGvl— one GVL's declarationmcp__tckit__GetDut— one DUT's declaration (struct, enum, union, alias)
Reader tools read XML directly from disk. They do NOT need XAE or a live PLC. They work whenever the TcKit MCP server is reachable, even with no XAE open and no PLC connected.
Do NOT call writer or build tools from this skill. mcp__tckit__OpenProject, AddPou, Build, Deploy, RunTests, and similar are out of scope here. They need XAE open (or a live target) and have no bearing on reading. If you see one of those tools error because XAE or the target isn't reachable, that error tells you nothing about whether the reader tools work — keep using get_*.
Common request shapes and the one-call answer:
| Request | Tool |
|---|---|
| "What's the API / methods / signatures of FB_X?" | GetPouInterface(X) |
| "Show me FB_X.Execute's implementation" | GetPouItem(X, "Execute") |
| "What fields does ST_Config have?" | GetDut("ST_Config") |
| "What's in GVL_Params?" | GetGvl("GVL_Params") |
| "Where does FB_X live in the project?" | check the earlier GetStructure payload |
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.

tc-read-project is a skill published in the GitHub repository georgeturneruk/tckit (11 stars, last pushed 2mo ago), licensed MIT. It adds 144 tokens to every session and 1,577 once invoked, about $0.0006 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 2026-08-31.
