Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00054 | $0.00747 |
| Opus 5.5 | $0.00022 | $0.00299 |
| Sonnet 5.5 | $0.00011 | $0.00149 |
| Haiku 4.5 | $0.00005 | $0.00075 |
Grade A, and why
framework-giraffe 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 2d 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Giraffe Framework
Every Giraffe rule is owned by Giraffe Standards, which inherits F# Standards and ASP.NET Core Standards. This skill inherits F# Programming and ASP.NET Core Framework and repeats neither: compile order, outcome shapes, service lifetimes, options, and host tests are theirs. It adds only the judgement at the boundary where a Giraffe handler meets them. Where a sentence here seems to state a rule, the standard decides.
Start From What the Project Records
Read the routing style the application records, its error-to-response mapping function, and the handler it uses for authorization. A new route follows the recorded style; a second style is a decision, not a local choice.
Compose the Chain in Order
Write the chain in the order the standard fixes, and read it back left to right:
- the route, with typed parameters;
- authentication and authorization;
- binding and validation;
- one call into the core; and
- the shared result mapping.
A chain where a later step appears earlier, such as binding before authorization, lets an unauthorized caller learn what the binder accepts. When a handler needs a step the chain lacks, add the step to the chain; do not repeat it inside the handler.
Bind Strictly, Then Convert
| Input arrives as | Handle it with |
|---|---|
| path parameters | the typed route, which rejects a malformed value before the handler runs |
| query or form fields | a strict binder, whose failure goes to the chain's error handler |
| a JSON body | a transport type with model validation, run by the validating handler |
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.

framework-giraffe is a skill published in the GitHub repository wahidyankf/ose-public (12 stars, last pushed today), licensed MIT. It adds 54 tokens to every session and 747 once invoked, about $0.0002 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 2026-10-14.
