What is forge AGENTS.md?

Repository guidance for coding agents working on Forge, a Rust program that provides a terminal-based AI coding assistant. It explains the project structure, development rules, checks, and Git workflow.

Use it when changing Forge code, understanding its crates, running checks, or following its feature-branch and pull-request process.

It gives an agent the project context and rules needed to make changes consistently and safely. It also clarifies how to validate work before submitting it.

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	$0.00716	$0.00716
Opus 5.5	$0.00286	$0.00286
Sonnet 5.5	$0.00143	$0.00143
Haiku 4.5	$0.00072	$0.00072

Security

Grade A, and why

forge 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 27d 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.

Project Overview

Forge is a Rust workspace for a terminal AI coding-agent harness. The main binary launches a full-screen TUI and lives in crates/forge-cli.

Key crates:

crates/forge-cli: CLI entrypoint and startup wiring.
crates/forge-tui: Ratatui terminal UI, overlays, commands, model picker, chat loop UI.
crates/forge-core: Agent loop, message/session lifecycle, tool execution orchestration.
crates/forge-model: Native provider transports and wire-format normalization.
crates/forge-connect: Provider profiles, credential store, model catalog, /connect support.
crates/forge-tools: Built-in tools and validation. Includes update_plan (model-callable checklist; emits a plan_update turn event; no persisted plan state) and ask_user_question (pauses the turn on WaitReason::Question until the user answers).
crates/forge-mcp: MCP client and remote tool registration.
crates/forge-config: Config loading and model/provider migration.
docs/: User/design documentation.

Development Rules

Keep changes focused; avoid unrelated refactors, dependency updates, or formatting churn.
Prefer small root-cause fixes over call-site patches.
Match existing Rust style and crate-local patterns.
Always run relevant tests for the code you change before handoff.
Add or update tests for behavior changes, and implement new test cases when changes are significant.
Update docs when commands, configuration, provider behavior, architecture, or safety behavior changes.
Never commit API keys, OAuth tokens, credentials, .forge/ runtime data, or proprietary fixtures.

Validation

Run only the tests that target the code you changed. Never run the full workspace test suite (cargo test --workspace); it is slow and agents should not spend time on it.

For any non-trivial code change, run the most relevant crate-level tests, filtered to the modules/behaviors you touched where possible.
For significant changes, add or expand targeted test coverage and run those new tests plus the directly affected ones.

Changes

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.
