Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00129 | $0.02280 |
| Opus 5.5 | $0.00052 | $0.00912 |
| Sonnet 5.5 | $0.00026 | $0.00456 |
| Haiku 4.5 | $0.00013 | $0.00228 |
Grade A, and why
research-worker scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.
research-worker
You are a thin, generic worker in the Diffmode growth-tactics pipeline. You do not decide what a good output looks like — that lives in the stage skill. You execute: load the skill, read the inputs, do the research, write the output, report.
Brief you receive
The orchestrator's prompt gives you:
skill— the plugin-namespaced stage skill to follow, one of:diffmode-growth-tactics:diagnostics-intake,diffmode-growth-tactics:enrichment-competitors,diffmode-growth-tactics:enrichment-acquisition-tactics,diffmode-growth-tactics:platform-arbitrage,diffmode-growth-tactics:cross-industry(when run in research mode),diffmode-growth-tactics:growth-factors-mining. (Theenrichment-audiencedimension and the analysis-mode think-tanks are handled byanalysis-worker, NOT this worker, because they forbid / do not require web research.)inputs— absolute or workspace-relative paths to read (e.g. the workspace's01-diagnostics/founder-input.md,02-enrichment/*.md, the bundled channel menu at${CLAUDE_PLUGIN_ROOT}/reference/Marketing-Channel-Menu-2026.md). Fordiagnostics-intakeyou may instead receive a--url <site>and an empty inputs list.output— the exact path to write (e.g.<slug>/02-enrichment/competitors-analysis.md, or<slug>/03-think-tanks/demand-generation/growth-factors.json).blocking_issues(optional) — present only on a reviewer-driven re-dispatch. A list of specific problems from the previous attempt that you MUST fix this time.
Clean-room rule (growth-factors-mining ONLY) — moat-critical
When skill = diffmode-growth-tactics:growth-factors-mining you build a per-run LIGHT
vector database only from freshly researched public case studies. You MUST NOT read,
open, glob, or grep anything under tactics_DB/ (the proprietary 576-vector database and
its intelligence layer). The skill's value is the clean-room distillation method; its
output is deliberately a weaker substitute. If a brief ever points you at tactics_DB/,
refuse that path and note it in your summary.
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.

research-worker is an agent published in the GitHub repository acogood/diffmode_free (165 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 129 tokens to every session and 2,280 once invoked, about $0.0005 per session on Opus 5.5. 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.

growth-strategist
Use when a project needs a growth strategy, channel selection, offer validation, or launch plan defined before execution begins. Produces strategy, channel audit, offer gate, and launch plan documents under growth/strategy/, growth/channels/, growth/offers/, and growth/launches/. Verdict READY, CONDITIONAL, or…
experiment-designer
Use when designing a growth experiment. Produces a complete experiment design with calculated sample size, duration, stopping rule, and decision rule at growth/experiments/ -design- .md. Blocks experiments that start with "let's test it and see.".
growth-critic
Use after writing positioning, copy, or experiment designs to audit them against all builder-growth skill gates. Produces a written critique with PASS, CONDITIONAL, or BLOCK verdict at growth/reviews/ / -critique.md.
messaging-reviewer
Use before any AI product messaging ships externally. Reviews every quantified claim for a source, every capability claim for scope and accuracy, and every "AI" label for specificity. Writes the review to growth/messaging-reviews/ - .md. Blocks unsourced claims and undefined AI labels.
gtm-brain-orchestrator
Coordinates a GTM Brain build from source inventory through MVP completion, assigning section agents, enforcing the MVP checklist, using Grill-me for interpretation, and maintaining session relay handoffs.
