What is rewind AGENTS.md?

A project guide for Rewind, a personal-data aggregation service that collects information from services such as Strava, Last.fm, and Plex. It explains its work modes, development commands, and system architecture.

It helps maintain the data sync service, REST API, image delivery service, database migrations, and MCP server.

It tells the coding assistant when to make a focused change and when to use stricter checks, while identifying operations that require approval.

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	$0.01460	$0.01460
Opus 5.5	$0.00584	$0.00584
Sonnet 5.5	$0.00292	$0.00292
Haiku 4.5	$0.00146	$0.00146

Security

Grade A, and why

rewind 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.

Rewind

Work modes

Default to exploration for UI, documentation, prototypes, and small changes. Make focused edits directly; do not require a formal spec, separate plan, worktree, or TDD.
Apply production rigor when the user explicitly asks to ship, harden, prepare a release, or use strict TDD. Match verification to risk and obey any stronger test requirements below.
Ask before deployments, remote D1 migrations, production-data changes, live API mutations, releases, or security-rule changes. A user request naming the exact mutation and target counts as approval for that operation.

Personal data aggregation service. Syncs data from Strava, Last.fm, Discogs, Plex, Letterboxd, and Instapaper into Cloudflare D1, serves via REST API at api.rewind.rest with an image CDN at cdn.rewind.rest. MCP server published as rewind-mcp-server on npm, deployed as a Cloudflare Worker at mcp.rewind.rest.

Read the nested guide before editing in its directory. Claude loads it automatically when it reads a file there; Codex loads it only when started inside that directory.

mcp-server/AGENTS.md: the MCP package's Node 22 and 24 support, its commands, manifest and docs regeneration, and release-please versioning.

npm run lint:claude  # claudelint (validate agent instruction files)
npm test             # Vitest

Agent configuration

AGENTS.md is the canonical cross-agent guide. Claude Code reads it directly, so there is no CLAUDE.md.
Repository skills live in .agents/skills. Claude consumes those same files through symlinks in .claude/skills; do not maintain a second copy.
Keep domain procedures such as adding and finding media project-scoped. General design, delivery, review, and hardening workflows come from the global agent-tooling setup.
See .agents/skills/README.md for the project inventory and mutation boundaries.

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.
