What is FixThis AGENTS.md?

A set of instructions for FixThis, a debugging companion for Android apps built with Jetpack Compose, Google's framework for creating Android user interfaces. The Android app reports connection status while a desktop console handles selection, notes, evidence, and handoff.

Routing tasks to the right project files, checking repository state, investigating bugs, making small compatible changes, and verifying results.

It gives agents a clear reading order and workflow for diagnosing or changing the project while preserving unrelated work and distinguishing reviews from authorized code changes.

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	$0.00810	$0.00810
Opus 5.5	$0.00324	$0.00324
Sonnet 5.5	$0.00162	$0.00162
Haiku 4.5	$0.00081	$0.00081

Security

Grade A, and why

FixThis 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 9d 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.

FixThis — Agent Operating Contract

FixThis is a debug-only Jetpack Compose sidekick. The Android app shows connection status. Selection, annotation, evidence, and handoff happen in the local desktop console.

Read Order

Read this file.
Read docs/index.md and the project map.
Run npm run agent:route -- --task console for an explicit route, or npm run agent:route -- --changed --json once paths are known.
Read only the maintained docs and first source files the router returns.
Treat docs/specs/* and docs/plans/* as historical context unless current source or maintained docs point there. Removed planning files remain available in Git history.

Current implementation wins over docs. docs/reference/* wins over historical planning.

Start

Run git status --short --branch, git log -5 --oneline --decorate, and git worktree list --porcelain before edits.
Leave unrelated dirty changes alone. Check whether another worktree owns the task.
Classify the request: explanation, diagnosis, implementation, review, release, connected proof, or feedback work.
Do not turn diagnosis or review into code changes without authorization.
Complete authorized work without repeated approval. Resolve routine choices from context; ask only when missing information affects correctness or scope.
User instructions take precedence over skill guidelines. If a skill blocks work, identify the exact rule and explain why it applies.

Change

Make the smallest compatible change. Follow the router’s maintained docs.
Keep compose-core free of MCP, CLI, Android UI, browser DTO, and .fixthis/ path dependencies.
Preserve persisted field names. Coordinate bridge changes through bridge protocol.
Use canonical generators. Never hand-edit build outputs.
Never commit .fixthis, screenshots, reports, fixture workspaces, or personal agent state.
Do not modify ~/.codex or project .codex for repository work.

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.
