Getting it into your agent
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.

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 | $0.00404 | $0.00404 |
| Opus 5 | $0.00202 | $0.00202 |
| Sonnet 5 | $0.00081 | $0.00081 |
| Haiku 4.5 | $0.00040 | $0.00040 |
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 primeto load current project state and the full tbd workflow. - Run
tbd skillfor the complete reusable tbd skill instructions. - Run
tbd shortcut --listandtbd guidelines --listfor on-demand resources. - Track all work as beads:

flowmark
Auto-format Markdown with flowmark for clean, semantic git diffs.
- Run
flowmark --auto <files>on Markdown you create or edit. - Run
flowmark --docsfor full usage andflowmark --skillfor the skill. - If
flowmarkis not onPATH, use a pinneduvxrunner (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.
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.
