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.

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 5.1 | $0.00008 | $0.02369 |
| Opus 5 | $0.00004 | $0.01184 |
| Sonnet 5 | $0.00002 | $0.00474 |
| Haiku 4.5 | $0.00001 | $0.00237 |
Grade A, and why
prp-implement scanned grade A 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

97% identical to prp-implement — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 386 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PRP Implement
Execute a plan file step-by-step with continuous validation. Every change is verified immediately — never accumulate broken state.
Core Philosophy: Validation loops catch mistakes early. Run checks after every change. Fix issues immediately.
Golden Rule: If a validation fails, fix it before moving on. Never accumulate broken state.
Phase 0 — DETECT
Package Manager Detection
| File Exists | Package Manager | Runner |
|---|---|---|
bun.lockb |
bun | bun run |
pnpm-lock.yaml |
pnpm | pnpm run |
yarn.lock |
yarn | yarn |
package-lock.json |
npm | npm run |
pyproject.toml or requirements.txt |
uv / pip | uv run or python -m |
Cargo.toml |
cargo | cargo |
go.mod |
go | go |
Validation Scripts
Check package.json (or equivalent) for available scripts:
# For Node.js projects
cat package.json | grep -A 20 '"scripts"'
Note available commands for: type-check, lint, test, build.
Phase 1 — LOAD
Read the plan file:
cat "$ARGUMENTS"
Extract these sections from the plan:
- Summary — What is being built
- Patterns to Mirror — Code conventions to follow
- Files to Change — What to create or modify
- Step-by-Step Tasks — Implementation sequence
- Validation Commands — How to verify correctness
- Acceptance Criteria — Definition of done
If the file doesn't exist or isn't a valid plan:
Error: Plan file not found or invalid.
Run /prp-plan <feature-description> to create a plan first.
CHECKPOINT: Plan loaded. All sections identified. Tasks extracted.
Phase 2 — PREPARE
Git State
git branch --show-current
git status --porcelain
Branch Decision
| Current State | Action |
|---|---|
| On feature branch | Use current branch |
| On main, clean working tree | Create feature branch: git checkout -b feat/{plan-name} |
| On main, dirty working tree | STOP — Ask user to stash or commit first |
| In a git worktree for this feature | Use the worktree |
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.

prp-implement is a command published in the GitHub repository sifxprime/kodelyth-ecc (11 stars, last pushed 4d ago), licensed MIT. It adds 8 tokens to every session and 2,369 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 97% identical to prp-implement, differing in 12 lines, and is treated as a copy.
Other commands, from other repositories
maintainer-review-test-coverage
Review the PR for test coverage — does new behavior have tests, are critical paths exercised, do existing tests still cover what they should (Pi-tuned).
assess
Ground one dependency-update request against this repository as it exists right now, and decide whether an update is actually owed. You produce an assessment and a verdict; you change nothing. No one watches the run; the assessment file and your declared fields are the only things that persist.
review-tests
Find one defect: the change establishes or alters meaningful behavior, and no test would fail when that behavior regresses in a plausible way. Tests protect outcomes and invariants — count, lines, and coverage percentages are not outcomes. Read-only: never modify files, commit, or post anywhere.
e2e-echo-command
E2E test command — echoes back the user message.
test-coverage
Analyze coverage, identify gaps, and generate missing tests toward the target threshold.
e2e
Generate and run E2E tests with Playwright.
