repren: Skill for Claude Code

.agents/skills/tbd/SKILL.md

tbd is a skill for Claude Code from jlevy/repren. It costs 262 tokens per session (6,830 once invoked), scanned A, original, MIT.

A Git-based toolkit for tracking issues, planning features, and guiding coding work. It also provides reusable engineering instructions, including guidance for test-driven development (TDD), where tests are written to shape the implementation.

In plain words
What is it for?
It helps create and manage bugs, features, and tasks; plan work from specifications; apply coding guidance; and use templates for reviews, commits, cleanup, and handoffs.
Why use it?
It keeps tasks and their dependencies in the repository and connects planning with implementation, reviews, and handoffs.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is jlevy/repren's own configuration. It tells Claude Code how to work on repren itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything repren configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

tbd 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 436 lines — stays where its author put it; the contents beside it link to each section on GitHub.

tbd helps humans and agents ship code with greater speed, quality, and discipline.

  1. Beads: Git-native issue tracking (tasks, bugs, features). Never lose work across sessions. Drop-in replacement for bd.
  2. Spec-Driven Workflows: Plan features → break into beads → implement systematically.
  3. Knowledge Injection: 25+ engineering guidelines (TypeScript, Python, TDD, testing, Convex, monorepos) available on demand.
  4. Shortcuts: Reusable instruction templates for common workflows (code review, commits, PRs, cleanup, handoffs).

Installation

npm install -g get-tbd@latest      # Install or upgrade the CLI (same command for both)
tbd setup --auto --prefix=<name>   # Fresh project (--prefix is REQUIRED: 2-8 alphabetic chars recommended. ALWAYS ASK THE USER FOR THE PREFIX; do not guess it)
tbd setup --auto                   # Existing tbd project — also the upgrade step (applies any format migration; commit the diff it reports)
tbd setup --from-beads             # Migration from .beads/ if `bd` has been used

If tbd refuses with “This repository requires a newer version of tbd”, run the two install/upgrade commands above.

Routine Commands

tbd --help    # Command reference
tbd status    # Status
tbd doctor    # If there are problems

tbd setup --auto   # Run any time to refresh setup
tbd prime      # Restore full context on tbd after compaction
tbd web --open # Open the live, read-only bead viewer

CRITICAL: You Operate tbd, the User Doesn’t

You are the tbd operator: Users talk naturally; you translate their requests to tbd actions. DO NOT tell users to run tbd commands. That’s your job.

  • WRONG: “Run tbd create to track this bug”

  • RIGHT: (you run tbd create yourself and tell the user it’s tracked)

Live browser requests: When the user asks to see, show, open, or view beads in a browser, start tbd web --open yourself with the agent platform’s long-running process facility. Do not merely print the command. If the requested project is outside your current working directory, start tbd web <path> --open; the path may be its repository root or any subdirectory. Wait for the startup descriptor, give the user its loopback URL, and leave the process running until they ask you to stop it or the session environment requires cleanup.

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.
