bedrock: Skill for Claude Code

.agents/skills/ask-matt/SKILL.md

ask-matt is a skill for Claude Code, Codex from christopher-buss/bedrock. It costs 22 tokens per session (2,730 once invoked), scanned A, a copy of ask-matt, MIT.

A skill that recommends which workflow or skill fits a situation. It acts as a guide through steps such as shaping an idea, planning, prototyping, and building.

In plain words
What is it for?
Use it to choose an appropriate agent workflow and route a project to the relevant skill.
Why use it?
It helps when you do not know which available skill or workflow to use next.

Skill for Claude CodeCodex

Written for Claude Code and Codex: disable-model-invocation in frontmatter, but also agents/openai.yaml present. Also seen: mentions subagents; installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is christopher-buss/bedrock's own configuration. It tells Claude Code and Codex how to work on bedrock 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 bedrock configures →

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

ask-matt 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 6d 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.

Ask Matt

You don't remember every skill, so ask.

A flow is a path through the skills. Most paths run along one main flow, and two on-ramps merge onto it. Everything else is standalone, or a vocabulary layer that runs underneath.

The main flow: idea → ship

The route most work travels. You have an idea and want it built.

  1. /grill-with-docs sharpens the idea by interview. Start here whenever you are working in a working directory: it's stateful, retaining what it learns in CONTEXT.md and ADRs. (No working directory? Use /grill-me instead, covered under Standalone. Both run the same /grilling primitive; grill-with-docs is the one that leaves a paper trail, which makes it the better of the two whenever a repo is there to leave it in.)

  2. Branch: can you settle every question in conversation? If a question needs a runnable answer (state, business logic, a UI you have to see), detour through a prototype, bridged by /handoff in both directions (a prototype lives in its own directory, which is exactly what /handoff is for; see Phase boundaries):

    • /handoff out, then open a fresh session against that file,
    • /prototype to answer the question with throwaway code,
    • /handoff back what you learned, and reference it from the original idea thread.
  3. Branch: is this a multi-session build?

    • Yes/to-spec (turn the thread into a spec), then /to-tickets to split it into tracer-bullet tickets, each declaring its blocking edges. On a local tracker that's one file per ticket under .scratch/<feature>/issues/, worked blockers-first by hand; on a real tracker the edges become native blocking links, so any ticket whose blockers are done can be grabbed: kick off /implement per ticket, /clearing context between each one. Each ticket is self-contained, so the last one's context is disposable.
    • No/implement right here, in the same context window.

    Either way, /implement builds each issue by driving /tdd internally (one red-green slice at a time), then closes out by running /code-review, a two-axis review (Standards + Spec) of the diff, before committing. Reach for /tdd on its own when you just want to build a concrete behaviour test-first without a full spec, and /code-review on its own whenever you want to review a branch or PR against a fixed point.

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.
