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 | $0.00035 | $0.17382 |
| Opus 5 | $0.00017 | $0.08691 |
| Sonnet 5 | $0.00007 | $0.03476 |
| Haiku 4.5 | $0.00003 | $0.01738 |
Grade A, and why
start 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 yesterday.
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.

The opening of the file, as written. The whole thing — 982 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Start — build your growth plan
Main-thread orchestrator for the Diffmode free growth-ideation pipeline — from a fast
founder intake all the way to a final synthesis.md of 7-9 novel demand-gen tactic
IDEAS, and it STOPS there. (A best-effort packaging stage then re-writes synthesis.md
as the founder-facing growth-tactics.md — same tactics, plain language, no new content.)
Prioritization, implementation guides, and the proprietary 576-vector database are the paid
product; this command never attempts them.
It runs the workflow as skills + worker sub-agents. It owns the DAG, the parallel fan-out, the reviewer-retry quality gate, and the stage-boundary checks.
This command runs in the main thread. It dispatches worker sub-agents via the Agent/Task tool, and it is the only place that may talk to the human (via AskUserQuestion, for intake). It must NOT itself be run as a sub-agent — sub-agents are one level deep and could not then spawn the workers. (See the repo's
docs/architecture.md— internal design notes, not shipped in the plugin.)

No host repo is required.
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.

start is a command published in the GitHub repository acogood/diffmode_free (159 stars, last pushed 21d ago), licensed Apache-2.0. It adds 35 tokens to every session and 17,382 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
