Snapshot async request configuration for HTTP sessions

Replaced retired Anthropic model ids with the recommended replacements: the default model in src/anthropic.c and decai (claude-sonnet-5-5), plus docs, examples and model lists.

Notice anthropic-retired-models-2026-10 about api.anthropic.com's API describes the change. It was read from a file and is not signed by the provider.

+## WASM HTTP
+
+With radare2's WASI HTTP build, decai defaults to `r2.http()` to reach the existing
+`r_socket_http_get/post` C APIs. Headers and JSON payloads go directly to the
+host HTTP adapter; no shell curl, temporary payload file or WebSocket proxy is
+needed. A failed/denied HTTP call is returned as an error, without a shell
+fallback. In `http=auto` mode, runtimes without `r2.http()` use system curl.
+
+Enable HTTP in the embedding application (`enabled: true` in JavaScript or
+`network=True` in Python). The radare2 sandbox must permit both `socket` and
+`network`; process execution is not needed. Browser requests remain subject
+to CORS. The host adapter controls the HTTP deadline in WASM; decai's `timeout`
+setting still controls native curl only. Responses are buffered, not streamed.
+
+This requires radareorg/radare2#27037 and the rebuilt decai script. For the
+C r2ai plugin compiled into WASM, the `auto` HTTP backend likewise selects
+radare2's C HTTP implementation; native backend selection is unchanged.

+# decai r2plugin
+
+Boilerplate to embed `decai.r2.js` inside the radare2 core library using the
+external plugin system (XPS). Unlike `r2ai/r2plugin`, this does not link any
+native code: the r2.js script is converted into a C buffer and registered as
+an embedded startup script, so r2 runs it at startup exactly like a file in
+the `plugins/*.r2.js` directory (honoring `cfg.plugins`).
+
+The `decai.r2.js` bundle is built from the typescript sources with
+`r2frida-compile` (see `make -C src` in the decai directory). The C buffer is
+generated at build time with `rax2 -C` (make builds) or `js2c.py` (meson).
+
+## Usage
+
+decai lives inside the r2ai repository, so expose it as `libr/xps/p/decai`:
+
+```console
+cd radare2/libr/xps/p
+git clone https://github.com/radareorg/r2ai
+ln -s r2ai/decai decai
+```
+
+For acr/make builds:
+
+```console
+cd radare2
+make -C libr/xps EXTERNAL_PLUGINS=decai
+./configure-plugins
+make
+```
+
+For meson builds, make `libr/xps/p/meson.build` contain:
+
+```meson
+subdir('decai/r2plugin')
+```

+
+Decai is the radare2 plugin for decompiling functions with the help of language models.
+
+By default uses a local ollama server, but can you can pick any other service by using 'decai -e api=?'.
+
+[0x00000000]> decai -e api=?
+r2ai deepseek anthropic claude gemini groq hf lmstudio mistral ollama ollamacloud openapi openai openrouter vllm xai zen
+
+## Using Ollama
+
+* Visit https://ollama.com to install it.
+* Download the model of choice: 'ollama run llama3.3'
+* Configure decai to use the given model with: 'decai -e model=?'
+
+These are the most recommended models for decompiling in local:
+
+* hhao/qwen2.5-coder-tools:latest (18GB of ram)
+* hhao/qwen2.5-coder-tools:32b (24GB of ram required)
+
+## Common Options
+* 'decai -e baseurl=<url>' override default host and port for API endpoint (e.g., 'http://localhost:11434')
+* 'decai -e apitype=chat|generate' choose the Ollama API endpoint (default: chat)
+* 'decai -e headers=Authorization: Bearer ...\\nUser-Agent: curl/8.7.1' add or override HTTP headers
+* "export DECAI_HEADERS='Authorization: Bearer ...\\nUser-Agent: curl/8.7.1'" set extra headers from the environment
+* 'decai -e http=auto|r2|curl' select the HTTP transport (default: auto, prefers r2.http)
+* 'decai -e timeout=0' disable curl timeouts, or set a positive number of seconds
+
+* 'decai -e deterministic=true' to remove randomness from decompilation responses
+* 'decai -e lang=Python' to output the decompilation in Python instead of C
+* 'decai -e hlang=Catalan' to add comments or explanations in that language (instead of English)
+* 'decai -e cmds=pdd,pdg' use r2dec and r2ghidra instead of r2's pdc as input for decompiling
+* 'decai -e prompt=..' default prompt must be fine for most models and binaries, feel free to tweak it
+
+## API Keys
+
+Remove services like OpenAI, Mistral, Anthropic, Grok, Gemini, .. require API keys to work.
+
+See 'decai -k' to list the status of available APIkeys
+Use 'decai -K' to edit apikeys.txt and 'decai -E' to edit decai.txt.
+
+Decai will pick them from the environment or the config files in your home:
+
+* echo KEY > ~/.r2ai.openai-key
+* export OPENAI_API_KEY=...
+* put one 'key=value' pair per line in ~/.config/r2ai/decai.txt
+
+## Using the R2AI Server:
+
+Install r2ai or r2ai-server with r2pm:
+
+[0x0000000]> decai -e api=r2ai
+[0x0000000]> r2pm -ci r2ai
+
+Choose one of the recommended models (after r2pm -r r2ai):
+
+* -m ibm-granite/granite-20b-code-instruct-8k-GGUF
+* -m QuantFactory/granite-8b-code-instruct-4k-GGUF
+* -m TheBloke/Mistral-7B-Instruct-v0.2-GGUF

+  auto: `# Radare2 Auto Mode
+
+Use function calling to execute radare2 commands in order to resolve the user request defined in the "User Prompt" section, analyze the responses attached in the "Command Results" section.
+
+## Function Calling
+
+Respond ONLY using plain JSON. Process user query and decide which function calls are necessary to solve the task.
+
+1. Analyze the user request to determine if we need to run commands to extend the knowledge and context of the problem.
+2. If function call is needed, construct the JSON like this:
+ - Fill the "action" key with the "r2cmd" value.
+ - Specify the "command" as a string.
+ - Optionally, provide a "reason" and "description"
+3. If the answer can be provided and no more function calls are required:
+ - Use the key "action": "reply".
+ - Include "response" with the direct answer to the user query.
+
+Return the result as a JSON object.
+
+### Sample Function Calling Communication
+
+Command Results: already performed actions with their responses
+User Prompt: "Count how many functions we have here."
+Response:
+{
+    "action": "r2cmd",
+    "command": "aflc",
+    "description": "Count functions"
+    "reason": "Evaluate if the program is analyzed before running aaa"
+}
+
+## Rules
+
+Use radare2 to resolve user requests.
+
+* Explain each step in the "reason" field of the JSON.
+* Follow the initial analysis instructions.
+* Output only valid JSON as specified.
+* Decompile and inspect functions, starting from main.
+* Run only the needed commands to gather info.
+* Use "@ (address|symbol)" to seek temporarily.
+* Output should be a verbose markdown report.
+* Use "sym." or "fcn." prefixes if "pdc" is empty.
+* If a seek fails, use "f~name" to find the symbol's address.
+
+### Initial Analysis
+
+1. Run "aflc" to count the number of functions
+2. If the output of "aflc" is "0" run "aaa" once, then "aflc" again
+3. Run only one command at a time (do not use ";")
+
+### Special cases
+
+* On Swift binaries run...

+# r2plugin
+
+This directory contains the make and meson files required to link r2ai
+inside radare2 through the external plugin system (XPS).
+
+```console
+cd radare2
+make -C libr/xps EXTERNAL_PLUGINS=r2ai
+./configure-plugins
+make
+```
+
+For meson builds, place this repository at `libr/xps/p/r2ai` and make
+`libr/xps/p/meson.build` include:
+
+```meson
+subdir('r2ai/r2plugin')
+```
+
+## WASI HTTP build
+
+Use a radare2 checkout with the host HTTP bridge and place this repository at
+`libr/xps/p/r2ai`. From that radare2 checkout:
+
+```sh
+echo 'EXTERNAL_PLUGINS+=r2ai' >> libr/xps/config.mk
+make -C libr/xps
+WASI_HTTP=1 sys/wasi-api.sh
+```
+
+This links the C plugin into the reactor; it does not load a native shared
+library at runtime. Enable HTTP in the host adapter. The `auto` backend selects
+`r_socket_http_get/post`, preserving provider authentication headers and JSON
+bodies, subject to the radare2 sandbox. `--disable-network` also denies these calls.
+
+WASI excludes POSIX signal/alarm handling; the host controls request timeouts,
+not `r2ai.http.timeout`. Normal queries and model listing use buffered HTTP.
+Vertex's automatic `gcloud` authentication and background tasks requiring
+threads are unavailable. Explicit shell backends (`system`/`curl`) cannot work;
+use `auto` or `socket`. Browser CORS and restricted-header rules still apply.
