What is openwebui_anthropic_api_manifold_pipe AGENTS.md?

Repository instructions for an OpenWebUI connection to Anthropic’s Messages API. They explain the code structure, generated files, request handling, streaming, caching, and build commands.

Maintaining model discovery, API request assembly, tool loops, streamed responses, prompt caching, Files API features, code execution, and related filters.

They show contributors where to edit the source and how to rebuild generated output, preventing changes from being lost or leaving the distributed files out of date.

Token cost

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	$0.02221	$0.02221
Opus 5.5	$0.00888	$0.00888
Sonnet 5.5	$0.00444	$0.00444

Security

Grade A, and why

openwebui_anthropic_api_manifold_pipe AGENTS.md 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.

Anthropic API Manifold Pipe — agent notes

Scope

This repo holds one OpenWebUI manifold pipe for the Anthropic Messages API plus its companion/toggle filters. Tasks usually touch model discovery, request payload assembly, the tool loop, content-block streaming, prompt caching, Files API / code execution / skills, or the toggle filters.

Golden rule

anthropic_pipe.py and anthropic_pipe.min.py are generated (both committed). Edit src/anthropic_pipe/**, then rebuild. Hand-edits to the generated sections are lost on the next build.

Build

Need	Command (from repo root)
Compile the single-file artifact	`python helpers/build_anthropic_pipe.py`
Minify it standalone (the build already does this)	`python helpers/minify_pipe.py anthropic_pipe.py -o anthropic_pipe.min.py --check`
Pull the current artifact back into the template	`python helpers/build_anthropic_pipe.py --refresh-template`
Check model-list caching and invalidation	`python helpers/test_model_cache.py` (fakes the Anthropic client, no network)
Check API key encryption at rest	`python helpers/test_valve_encryption.py` (runs against the built artifact)

--refresh-template overwrites src/anthropic_pipe/pipe_template.py with the current artifact minus its generated sections. Use it only when the template drifted, never as a normal step.

The build works by marker pairs (# BEGIN/END GENERATED SECTION: anthropic_pipe.<section>) inside the template. Marker order in the template pins section order in the artifact — a module must appear above any code that annotates against it, because the build strips from __future__ import annotations.

File map

Path	Role
`src/anthropic_pipe/pipe_template.py`	Template for the pipe module: docstring/frontmatter (title, version, requirements), `class Pipe`, valves, generated-section markers. Version bumps and changelog live here.
`src/anthropic_pipe/request/payload.py`	Payload assembly source of truth: messages, tools, betas, thinking, Files API, context management, cache-control inputs. Compiled into a module-level `create_request_payload()`.
`src/anthropic_pipe/request/{cache_control,messages,tools,files,rag}.py`	`Pipe` method groups for the request half of a turn.
`src/anthropic_pipe/response/*.py`	Response half: one module per Anthropic content-block family (`text_block`, `thinking_block`, `client_tool`, `server_tool`, `code_execution_results`, `web_tool_results`, `internal_tool_results`, `compaction_block`, `status_events`) plus `state`, `handlers`, `registry`, `runtime`, `formatting`.
`src/anthropic_pipe/shared/{models,tasks}.py`	Model discovery/capabilities and OpenWebUI task handling (title, tags, follow-ups, memory review).
`src/anthropic_pipe/pipe_orchestrator.py`	`Pipe.pipe()` request orchestration and the high-level tool loop.
`helpers/build_anthropic_pipe.py`	Compiles `src/` into `anthropic_pipe.py`.
`helpers/minify_pipe.py`	Strips comments/docstrings (keeps the module docstring OpenWebUI parses) for the upload artifact.
`anthropic_pipe.py`	Generated single-file OpenWebUI artifact (committed; this is what users install).
`anthropic_pipe.min.py`	Generated minified artifact. Committed too -- it is offered as an install source, so it must never lag behind `anthropic_pipe.py`. The build writes both.
`anthropic_manifold_companion_filter.py`	Routes OpenWebUI's built-in web_search / code_interpreter buttons to Anthropic-native tools.
`anthropic_pipe_{thinking,web_search,code_execution,files}_toggle.py`	One-shot toggle filters.
`README.md`	User-facing docs: install, valves, changelog. Keep the changelog in sync with the template docstring.

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.
