What is devkit-knowledge?

A reference guide for the Cadre DevKit, covering its files, commands, skills, hooks, agents, and workflows. It points you to the actual files as the source of truth.

Use it when answering questions about DevKit structure, creating commands or skills, debugging hooks, or understanding skills versus agents.

It reduces the time spent searching for how the DevKit is organized or how a feature should be added.

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.

agentmods

npx agentmods add skills/benshapyro/cadre-devkit-claude/devkit-knowledge

Any agent

npx skills add benshapyro/cadre-devkit-claude --skill devkit-knowledge

Clone the repo

git clone --depth 1 https://github.com/benshapyro/cadre-devkit-claude

Made for: Claude Code, Codex.

Or install cadre-devkit-claude, the plugin that ships this one along with the rest of its 10 skills, 10 commands, 7 agents, 3 hooks.

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	$0.00035	$0.00661
Opus 5	$0.00017	$0.00331
Sonnet 5	$0.00007	$0.00132
Haiku 4.5	$0.00003	$0.00066

Security

Grade A, and why

devkit-knowledge 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.

Cadre DevKit Knowledge Base

This skill helps you find information in the devkit. Read the actual files - they are the source of truth.

Where to Find Things

Topic	Location
Global config	`~/.claude/CLAUDE.md`
Commands	`~/.claude/commands/*.md`
Skills	`~/.claude/skills/*/SKILL.md`
Hooks	`~/.claude/hooks/` + `settings.json`
References	`~/.claude/references/*.md`
Agents	Defined in system, use `Task` tool

Quick Answers

How do I add a command?

Create ~/.claude/commands/my-command.md:

How do I add a skill?

Skills vs Agents?

Skills = Knowledge (methodology, templates, best practices)
Agents = Workers (spawned via Task tool to do tasks independently)

Skills inform how to do something. Agents actually do things.

Debug hooks not running?

Enable debug mode: CLAUDE_HOOK_DEBUG=1
Check settings.json has hook registered
Verify file is executable (chmod +x)

Skill not activating?

Check YAML frontmatter is valid (name + description)
Ensure description has trigger keywords
Try explicit reference: "Use the X skill"

Command workflow?

New Project:

/greenfield → SPEC.md + DESIGN.md + PLAN.md → /plan [feature] → implement → /review → /validate → /ship

Existing Project:

/plan [feature] → implement → /slop (optional) → /review → /validate → /ship

Research:

/research [topic] → findings → /progress (save as docs)

Project vs Global

Location	Scope
`~/.claude/`	All projects (personal)
`./.claude/`	This project only (team)

Project-level config takes precedence over global.

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.

devkit-knowledge is a skill published in the GitHub repository benshapyro/cadre-devkit-claude (9 stars, last pushed 9mo ago), licensed MIT. It adds 35 tokens to every session and 661 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
