repren AGENTS.md

Project instructions for using tbd, a tool that tracks software work as issues and plans, and flowmark, a tool that formats Markdown documents.

In plain words
What is it for?
Loading project guidance, creating and closing tracked tasks, checking available engineering instructions, and formatting Markdown files.
Why use it?
They tell the coding assistant where to find project rules, how to record work, and how to keep documentation consistently 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.

Security

Grade A, and why

repren 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 3d 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.

What it actually says

IMPORTANT: You MUST read ./docs/development.md and ./docs/docs-overview.md for project documentation. (This project uses Speculate project structure.)

IMPORTANT: Before adding or upgrading any dependency, read ./SUPPLY-CHAIN-SECURITY.md.

tbd

This repository uses tbd for git-native issue tracking (beads), spec-driven planning, and on-demand engineering guidelines. As the agent, you operate tbd on the user’s behalf: translate their requests into tbd actions rather than telling them to run commands.

  • Run tbd prime to load current project state and the full tbd workflow.
  • Run tbd skill for the complete reusable tbd skill instructions.
  • Run tbd shortcut --list and tbd guidelines --list for on-demand resources.
  • Track all work as beads: tbd create, tbd ready, tbd close, and tbd sync.

flowmark

Auto-format Markdown with flowmark for clean, semantic git diffs.

  • Run flowmark --auto <files> on Markdown you create or edit.
  • Run flowmark --docs for full usage and flowmark --skill for the skill.
  • If flowmark is not on PATH, use a pinned uvx runner (never @latest).
  • Fast Rust port (recommended): uvx --from flowmark-rs==0.3.2 flowmark.
  • Python build (library / newest patch): uvx --from flowmark==0.7.3 flowmark.
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.
