resource-development

resource-development is a skill for Claude Code, Codex from kucherenko/gangsta. It costs 42 tokens per session (986 once invoked), scanned A, original, MIT.

A planning process that turns an agreed software contract into small, testable work packages. It assigns each package to a codebase area and defines its files, acceptance checks, dependencies, and resource budget.

In plain words
What is it for?
Breaking requirements into tasks, assigning ownership, setting acceptance criteria, choosing verification commands, estimating effort, and preparing isolated work areas.
Why use it?
It makes a large coding job easier to divide, verify, and run in parallel without losing track of requirements.

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

resource-development 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.

Resource Development: Infrastructure and Tooling

Overview

The Underboss decomposes the signed Contract into Work Packages, sets up infrastructure for parallel execution, and produces the Execution Plan — the detailed task breakdown that governs The Hit.

Trigger

Invoked after the Don signs the Contract (The Sit-Down complete).

Process

Step 1: Decompose Contract into Work Packages

For each requirement in the Contract:

  1. Identify affected files (create/modify)
  2. Determine territory ownership (which Crew Lead)
  3. Define acceptance criteria (from Contract)
  4. Write verification command
  5. Estimate token budget

Each Work Package must be:

  • Independent — Can be implemented without waiting for other Work Packages (within the same territory, order may matter)
  • Verifiable — Has a specific test or command that proves it works
  • Bite-sized — 2-5 minutes of Worker tasks
  • Traceable — References a specific Contract clause

Step 2: Define Territories

Group Work Packages by domain and define Crew Lead territories:

## Territory: <Name>
**Domain:** <Description>
**Files:** <Glob patterns>
**Work Packages:** WP-001, WP-003, WP-007
**Workers:** <Parallel count>
**Budget:** <Token allocation>

Step 3: Set Up Isolation

If the project uses git:

  • Create a branch for the Heist: heist/<heist-name>
  • Optionally create worktrees per territory for true parallel work

If not:

  • Document the isolation strategy (directory copies, etc.)

Step 4: Verify Prerequisites

Before The Hit begins:

  • All existing tests pass on the current baseline
  • Required dependencies are available
  • File paths in Work Packages are valid
  • No merge conflicts with the base branch

Step 5: Produce Execution Plan

Compile everything into the Execution Plan.

Execution Plan Format

Save to: docs/gangsta/<heist-name>/plans/YYYY-MM-DD-execution-plan.md

---
heist: <heist-name>
date: YYYY-MM-DD
total-work-packages: <N>
territories: <N>
estimated-total-budget: <tokens>

# Execution Plan: <Heist Name>

## Territories

### Territory: <Name 1>
**Crew Lead Domain:** <description>
**Files:** <globs>
**Workers:** <N parallel>
**Budget:** <tokens>

### Territory: <Name 2>
...

## Work Packages

**Prevention Guidance (all Work Packages):** Do NOT reproduce Gangsta-internal spec identifiers (FR-xxx, NFR-xxx, WP-xxx, where xxx is one or more digits) in any deliverable — source code, test files, code comments, or documentation. These identifiers belong only in `docs/gangsta/`.

### WP-001: <Title>
**Territory:** <Name>
**Contract Clause:** <FR-NNN>
**Files:**
- Create: `path/to/file`
- Test: `tests/path/to/test`
**Acceptance Criteria:**
1. <criterion>
**Verification:** `<command>`
**Budget:** <tokens>
**Dependencies:** None | WP-XXX

### WP-002: <Title>
...

## Execution Order
1. Independent packages (can run in parallel): WP-001, WP-002, WP-005
2. Depends on group 1: WP-003 (needs WP-001)
3. ...

## Baseline Verification
- Tests: <PASS/FAIL — must be PASS>
- Dependencies: <OK/MISSING>
- Branch: heist/<heist-name> created from <base>

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.

resource-development is a skill published in the GitHub repository kucherenko/gangsta (81 stars, last pushed 22d ago), licensed MIT. It adds 42 tokens to every session and 986 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 2026-08-30.
