Init is an agent skill from mattgierhart/PRD-driven-context-engineering.

Requirements

Workflow steps

What it can do on your machine

Read from SKILL.md and the folder at commit 30ed1b0. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Read
- Write
- Edit
- Glob
- Grep
- Bash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- bash
- python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Init loads about 1.2k tokens when it runs. Until then it costs about 145 tokens; SKILL.md has 505 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~145
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

The automated check noted patterns worth knowing about, such as sudo or a known installer.

NotePre-approves every shell command (allowed-tools: Bash)SKILL.md

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

/prd-ce:init — Greenfield Scaffold Seeder

Plant the consumer-owned scaffold for a fresh PRD-CE project. The methodology engine (lifecycle skills, the agent squad, governance hooks, readiness.py) is delivered live by the installed prd-ce plugin — it never gets copied into your repo. This skill seeds only what is yours to own and edit: PRD.md, the SoT/ graph, epics/ templates, your .claude/domain-profile.yaml, and per-agent MEMORY.md starters.

One manifest, no drift. The seed list comes from install-manifest.yaml's template_seed section — the same list install.sh (fork path) and ghm-template-sync (update path) read. This skill drives the deterministic prd-ce-init.sh so behavior is identical no matter who invokes it.

Scope (v1): greenfield only. This seeds an empty structure into a fresh repo. Mid-build and live-codebase on-ramps (entry-mode branching, graph extraction) are backlogged — see temp/plugin-conversion-plan.md. If the target already has PRD.md or SoT/ content, the seeder keeps it (non-destructive) rather than adapting to it.

Consumes

${CLAUDE_PLUGIN_ROOT}/templates/ — the bundled seed sources (mirrors template_seed paths) the packager ships with the plugin.
install-manifest.yaml template_seed + never_touch — authoritative seed/skip lists.
scripts/prd-ce-init.sh — the deterministic seeder this skill drives.

Produces

A seeded scaffold in the target repo (no new SoT IDs — this skill places templates, it does not author specs).
A freshly reset PRD.md (frontmatter at v0.1, today's date, no stale template_version).
A verification report (hooks emit valid JSON; readiness.py runs).

Workflow

Phase 1 — Preflight

Confirm git, python3, bash are present. Warn (don't block) if the target isn't a git repo.
Confirm greenfield: if PRD.md or non-empty SoT/ already exist, say so and stop — the seeder will keep them untouched, so there is nothing for init to do. (Point the user at the lifecycle skills to keep building, not at re-seeding.)

Phase 2 — Wizard questions

Ask only what changes the outcome (honor the execution mode's budget):

Target directory (default: current repo).
Domain profile: product (default) · library · infrastructure · research. Quick mode skips this and takes the default.

Show full SKILL.md (194 more words)Show less

Phase 3 — Seed (drive `prd-ce-init.sh`)

Run the deterministic seeder so behavior matches every other path:

bash

bash "${CLAUDE_PLUGIN_ROOT}/scripts/prd-ce-init.sh" --target <DIR> --dry-run   # preview
bash "${CLAUDE_PLUGIN_ROOT}/scripts/prd-ce-init.sh" --target <DIR>             # seed

Show the --dry-run plan first [standard+], then execute.
The seeder skips any file that already exists (never_touch honored) and resets a freshly seeded PRD.md frontmatter to v0.1.
After seeding, if the chosen domain profile differs from the default, update the profile: key in the seeded .claude/domain-profile.yaml [standard+].

Phase 4 — Verify (trust-but-verify)

Run each plugin hook against the target; assert valid JSON on stdout.
Run python "${CLAUDE_PLUGIN_ROOT}/scripts/readiness.py" run — a BLOCK on an empty scaffold is the gate working (no content yet), not a failure. Report the score.
Print next steps: customize README.md + PRD.md, then "Let's frame the problem" (v0.1).

Anti-patterns

Pattern	Fix
Hardcoding the seed file list in the skill	Drive `prd-ce-init.sh`; it reads `template_seed`
Copying the framework (skills/hooks) into the consumer repo	The plugin provides those live — seed only consumer-owned files
Overwriting an existing `PRD.md`/`SoT/`	Greenfield-only; the seeder skips what exists
Leaving `PRD.md` at the example's version header	Frontmatter reset to v0.1 happens automatically on a fresh seed
Treating a readiness BLOCK on a fresh scaffold as a bug	It's the gate working — report the score

Questions about Init

What does Init do?

Seed a fresh (greenfield) repository with the PRD-Driven Context Engineering scaffold — PRD.md, SoT/ knowledge files, EPIC templates, domain-profile config, and agent MEMORY starters. Init is an agent skill from mattgierhart/PRD-driven-context-engineering.md, SoT/ knowledge files, EPIC templates, domain-profile config, and agent MEMORY starters.

When should I use Init?

Init fits situations like: set up PRD lifecycle here; scaffold a new PRD-CE project; initialize the methodology.

How do I install Init in Claude Code?

Run `npx skills add mattgierhart/PRD-driven-context-engineering --skill init -a claude-code`. Or copy the skill folder (.claude/skills/init in mattgierhart/PRD-driven-context-engineering) into .claude/skills/init in your project. Claude Code loads it when a task matches its description.

How do I install Init in Codex?

Run `npx skills add mattgierhart/PRD-driven-context-engineering --skill init -a codex`. Or copy the skill folder (.claude/skills/init in mattgierhart/PRD-driven-context-engineering) into .agents/skills/init in your project. Codex loads it when a task matches its description.

Can I use Init in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mattgierhart/PRD-driven-context-engineering --skill init -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/init, .gemini/skills/init, .github/skills/init and .opencode/skills/init in your project.

What does Init need to run?

Going by SKILL.md and its folder, Init needs the command-line tools its instructions call (bash and python). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Write, Edit, Glob, Grep, Bash.

Does Init access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Init safe to install?

Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Init use?

Init is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Init use?

About 1.2k tokens (SKILL.md is roughly 4.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Init?

Skills that share tags, products or a category with Init: Pmstudio Comms (coco-research/coco, 513 stars), Saga (warpdotdev/common-skills, 610 stars), CCPM Project Management (automazeio/ccpm, 8.4k stars) and Memori Long-Term Memory (MemoriLabs/Memori, 17k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Init?

mattgierhart (a GitHub user) maintains it in mattgierhart/PRD-driven-context-engineering, which has 180 GitHub stars. The repository holds 45 skills in this directory. The repository was last updated on August 31, 2026.
