What is Fuse AGENTS.md?

Project instructions for Fuse, a .NET tool that gathers and reduces code so an AI agent can understand a project with fewer file lookups.

Use them when editing Fuse source code or documentation, especially when working with its code-collection, reduction, indexing, retrieval, and context components.

They preserve important project context between work sessions and explain how the codebase is organised, built, tested, and formatted.

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.

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	$0.10172	$0.10172
Opus 5	$0.05086	$0.05086
Sonnet 5	$0.02034	$0.02034
Haiku 4.5	$0.01017	$0.01017

Security

Grade A, and why

Fuse 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 4d 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.

Fuse - Agent and Contributor Guide

Read this before editing Fuse source or docs. It holds the durable context about the project so a session does not need it repeated in a prompt. For the full project briefing (architecture, all benchmark methodology and results, roadmap history), see briefing.md at the repo root.

What Fuse Is

Fuse is a .NET-native codebase context optimizer for AI-assisted development. It collects source files, reduces them for token efficiency, and emits one structured payload an agent or developer can read in a single call instead of opening thousands of files. It ships as a .NET global tool (fuse) and as a Model Context Protocol server (fuse mcp serve). It cuts tokens while keeping the public API intact, scopes to the files a task needs, and trims the round-trips an agent makes during its explore phase.

Repository Layout

src/Core: the pipeline and engine libraries - Fuse.Collection (discovery), Fuse.Reduction, Fuse.Emission, Fuse.Fusion (the orchestrator), Fuse.Indexing (the SQLite store and graph), Fuse.Semantics (workspace load, extraction, refactors), Fuse.Retrieval (ranking and resolution), Fuse.Scoping, Fuse.Context, Fuse.Workspace (resident compilation and test running).
src/Host: the executable surfaces - Fuse.Cli (CLI commands, the MCP server, and the fuse host daemon) and Fuse.BuildCaptureWorker (the out-of-process compiler-log worker).
src/Plugins: Fuse.Plugins.Abstractions, Fuse.Plugins.Languages.CSharp, Fuse.Plugins.Languages.CSharp.Roslyn, Fuse.Plugins.Formats.Web.
src/Packaging: Fuse.Capture, the build-target channel package (an MSBuild .targets file, no assembly).
tests/: unit, golden-output, architecture, and integration tests. tests/benchmarks/: the harness, corpus manifest, and recorded results, in their own solution.
site/: the documentation website (Next.js + Fumadocs), published at fuse.codes. All prose documentation lives here as MDX under site/content/docs; site/public holds the published static assets, including the fuse.json schema.
assets/: the benchmark figure (fuse-benchmarks.png and .svg) and the chart-generating script. mcp-registry/: the MCP Registry server manifest.
briefing.md (repo root): full project briefing for planners (architecture, benchmarks, gaps); see also roadmap/ for executable plans.
Solutions: Fuse.slnx is the product; Fuse.Benchmarks.slnx holds the benchmark harness and is deliberately excluded from the product build and package.

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.

Fuse AGENTS.md is an instructions file published in the GitHub repository Litenova-Solutions/Fuse (34 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 10,172 tokens to every session, about $0.0509 per session on Opus 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 2026-08-30.
