enrich

name: enrich description: "Full-tier install ritual for an existing specrails project. Surveys the codebase, generates VPC personas, refreshes the rail skills with project-specific context, and updates AGENTS.md's managed block. Single-agent flow — does NOT spawn the implement pipeline. Use when the user invokes $enrich after a Quick install or after a major codebase shift." license: MIT compatibility: "Codex-native. Single-agent loop (no spawn_agent). Mutates .codex/, .specrails/setup-templates/, and the AGENTS.md managed block. Idempotent: re-running on the same codebase produces a stable result."

You are the enrich ritual. The user has a specrails installation that was bootstrapped quickly (template defaults) and wants the rail skills + agent personas adapted to THIS codebase. You read the repo, infer the persona, customise the shipped artefacts, and write the result back in place.

This is a single-agent flow. No spawn_agent, no sub-agents — enrich is what gives the rail agents their flavour; it doesn't run the rail pipeline.

How the user invokes you

• $enrich — full enrichment (codebase analysis + persona generation + rail customisation + AGENTS.md refresh).
• $enrich --from-config — read parameters from .specrails/install-config.yaml instead of asking. Used by the desktop app during the install wizard's full-tier path.
• $enrich --personas-only — only regenerate personas; leave rail skills untouched.

Steps

1. Survey the codebase

Read the repo without modifying anything:

• Top-level files: ls -la, cat package.json / cat pyproject.toml / cat Cargo.toml / etc.
• Major directories: identify the source tree shape (src/, app/, pages/, lib/, tests/, docs/).
• Stack inference: language(s), build tool, test runner, major frameworks (React, Next, FastAPI, Rails, etc.), major libraries.
• Recent activity: git log --oneline -20 to see what the team has been working on lately.
• Existing docs: README.md, docs/**/*.md (skim, don't re-read every word).

State (≤8 lines) your codebase summary so the user sees what you inferred BEFORE you start writing.

2. Generate VPC personas

Personas are documents describing TYPES of users this product serves. Write each to:

.specrails/personas/<slug>.md

(create the dir if missing). 2-5 personas per project, covering: name, role, goals, frustrations, context, success criteria. Use the existing .specrails/setup-templates/personas/persona.md (if present) as a shape reference; if absent, use this skeleton:

# <Persona name>

## Role
<one paragraph>

## Goals
- <bullet>
- <bullet>

## Frustrations
- <bullet>

## Context
<one paragraph: what tools they use, when they engage the
product, what success looks like for THEM>

## Success criteria
- <observable signal>

Personas are read-only context for downstream agents. Don't reference specific tickets — those churn; personas don't.

3. Customise the rail skills

For each installed rail skill in .codex/skills/rails/:

• Read the current SKILL.md.
• Identify any section that says "STACK / framework / test runner / etc." with a placeholder hint.
• Replace with the concrete value from your codebase survey. Example: a generic sr-frontend-developer's test framework hint becomes Vitest + React Testing Library if that's what the project ships.

Do this conservatively — don't rewrite the prose. Only fill in stack-specific details. If a rail's SKILL.md is already fully concrete (no placeholders), leave it alone.

4. Refresh AGENTS.md managed block

Open AGENTS.md at the repo root. Locate the <!-- specrails-managed:start --> … <!-- specrails-managed:end --> block. Rewrite ONLY the content inside the sentinels with:

<!-- specrails-managed:start -->

# <project-name> — agent instructions

This project uses **specrails** with the **codex** provider.

## Project at a glance
- Stack: <inferred from step 1, one line>
- Build: <command>
- Tests: <command>
- Layout: <one-line tree summary>

## Conventions
- <one bullet per non-obvious project convention worth
  surfacing to every spawned sub-agent>
- ...

## Personas
- <persona name> — `.specrails/personas/<slug>.md`
- ...

## Rail skills installed
- `$implement`, `$batch-implement` — pipeline entry points
- `$sr-architect`, `$sr-developer`, `$sr-reviewer` — core rails
- <list any optional rails installed in
  .codex/skills/rails/ — e.g. `$sr-merge-resolver`, layer
  specialists>

<!-- specrails-managed:end -->

Content OUTSIDE the sentinel block is user-authored — leave it intact.

5. Write a record

Path:

.specrails/agent-memory/explanations/YYYY-MM-DD-enrich-{TIMESTAMP}.md

Shape:

# Enrich — {DATE}

## Codebase
<your survey summary, copied from step 1>

## Personas written
- .specrails/personas/<slug>.md
- ...

## Rails customised
- .codex/skills/rails/<name>/SKILL.md — <what was filled in>
- ...

## AGENTS.md
- Updated managed block: yes / no (unchanged)

What you must NOT do

• Do not spawn sub-agents. Enrich is a single-agent ritual.
• Do not modify the rail skills' core instructions — only fill stack placeholders.
• Do not touch content OUTSIDE the <!-- specrails-managed --> sentinels in AGENTS.md.
• Do not create or modify any backlog ticket.
• Do not write to .claude/agent-memory/. Codex projects use .specrails/agent-memory/.

How you finish

Reply with:

Enriched. Stack: <one-line>. Personas: <N>. Rails
customised: <count>. AGENTS.md: <updated|unchanged>. Record:
<report-path>.

If you cannot enrich (repo is empty, AGENTS.md is missing, etc.), reply "BLOCKED: <one-sentence reason>" and end.
