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 | $0.00039 | $0.00356 |
| Opus 5.5 | $0.00016 | $0.00142 |
| Sonnet 5.5 | $0.00008 | $0.00071 |
| Haiku 4.5 | $0.00004 | $0.00036 |
Grade A, and why
dotnet-managedcode-markitdown 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 1mo 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.
This is a copy
91% identical to managedcode-markitdown — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
ManagedCode.MarkItDown
Trigger On
- integrating
ManagedCode.MarkItDowninto document ingestion flows - converting office or rich-text content into Markdown for downstream processing
- reviewing indexing, chunking, or AI-preparation pipelines that depend on Markdown output
- documenting file-conversion steps for a .NET application
Workflow
- Identify the document sources the app actually handles.
- Decide where Markdown conversion belongs in the pipeline:
- before indexing
- before chunking
- before AI summarization or enrichment
- Keep conversion isolated behind one ingestion or processing service instead of scattering format handling everywhere.
- Validate real converted output for structure, links, headings, and attachment handling.
- Document which downstream stage depends on the produced Markdown.

Deliver
- guidance on where ManagedCode.MarkItDown fits in a real processing pipeline
- conversion-boundary recommendations for application design
- output-validation expectations for document ingestion
Validate
- the converted Markdown is good enough for the actual downstream consumer
- conversion is isolated in one clear pipeline step
- tests or review samples cover the real input formats the application claims to support
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
