codebase-adapter

Instructions for adapting the files of the ts-dev-kit plugin to the project where the plugin is installed. A plugin is an add-on that gives a coding agent extra instructions or tools.

In plain words
What is it for?
Use them during first-time installation, after a project structure or technology change, or when the plugin points to missing files, skills, or services.
Why use it?
They help align the plugin with the project’s actual folders, technologies, installed agents, and available tools while preserving the plugin’s core workflow.

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.

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 B, and why

codebase-adapter scanned grade B with 1 finding 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 2d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

**Available MCPs** — read `.claude/settings.json` in project root (and `~/.claude/settings.json` as fallback). Extract `mcpServers` keys.

How it starts

The opening of the file, as written. The whole thing — 246 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pre-injected project snapshot (verify in phase 2 — do not skip discovery):

Working directory: !pwd

Lockfile detected: !ls bun.lock pnpm-lock.yaml yarn.lock package-lock.json 2>/dev/null | head -1 || echo "none"

Agents installed: !ls .claude/agents/ 2>/dev/null | tr '\n' ' ' || ls agents/ 2>/dev/null | tr '\n' ' ' || echo "(not found)"

MCP servers configured: !python3 -c "import json; s=json.load(open('.claude/settings.json')); print(', '.join(s.get('mcpServers',{}).keys()) or '(none)')" 2>/dev/null || echo "(not found)"

package.json: !cat package.json 2>/dev/null || echo "(not found)"

You MUST NOT change:

  • Any <phase_*> logic or step sequences
  • Dispatch protocols, decomposition rules, execution mode decisions
  • Core agent principles, role descriptions, or behavior narratives
  • Output template formats or section headers
  • Skill descriptions or their trigger conditions
  • XML tag structures (<workflow>, <domain_areas>, <skill_map>, etc.)

<phase_1_locate_plugin> Find the plugin root. Try in order:

  1. skills/execute-task/SKILL.md exists in current directory → user is inside the ts-dev-kit repo.
  2. node_modules/@jgamaraalv/ts-dev-kit/ → installed via npm.
  3. Search upward and in siblings for a directory containing plugin.json with "name": "ts-dev-kit".

Store the resolved plugin root. All edits in phases 3–5 use paths relative to it. </phase_1_locate_plugin>

<phase_2_project_discovery> Determine the target project root ($ARGUMENTS if provided, otherwise current working directory).

Discover with Read, Glob, Grep — verify everything, assume nothing.

Package manager — detect from lockfile: bun.lock → bun, pnpm-lock.yaml → pnpm, yarn.lock → yarn, package-lock.json → npm.

Monorepo — check for workspaces in package.json, pnpm-workspace.yaml, or turbo.json. Record workspace names and their paths.

Tech stack — read package.json dependencies in root and each workspace:

  • HTTP framework: Fastify, Express, Hono, Elysia, or none
  • ORM/DB: Drizzle, Prisma, Kysely + database type (PostgreSQL, MySQL, SQLite)
  • Frontend: Next.js (detect App Router via app/ directory), Vite + React, or none
  • Validation: Zod (check version — v3 imports from "zod", v4 imports from "zod/v4"), Valibot
  • Queue: BullMQ, or none
  • Cache: ioredis, @upstash/redis, or none
  • Testing: Vitest or Jest; Playwright or Cypress
  • Docker: check for Dockerfile or docker-compose.yml

Project paths (verify with Glob — record exact paths):

  • Backend source root (e.g., apps/api/src/, src/)
  • Routes/handlers directory
  • DB schema + migrations directory
  • DB client file (search for database connection setup)
  • Redis client file (search for Redis instantiation)
  • Frontend source root (e.g., apps/web/, src/)
  • Shared package: directory path and package name (e.g., packages/shared/, @acme/shared)

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

codebase-adapter is a skill published in the GitHub repository jgamaraalv/ts-dev-kit (15 stars, last pushed 6mo ago), licensed MIT. It adds 147 tokens to every session and 3,060 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
