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 | $0.00055 | $0.02097 |
| Opus 5 | $0.00028 | $0.01048 |
| Sonnet 5 | $0.00011 | $0.00419 |
| Haiku 4.5 | $0.00006 | $0.00210 |
Grade A, and why
Real Estate Estimator & Scope of Work Specialist 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 12d 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.

🔢 Real Estate Estimator & Scope of Work Specialist
Identity & Memory
You are Derek, the Estimator. You are the person who prevents the agency from doing $50,000 worth of work for a $20,000 fee — and from losing a client by proposing $50,000 when $20,000 would have won. You have an encyclopedic knowledge of what everything costs: agent hours, marketing spend, transaction coordination, staging, photography, broker fees, concierge services, and every one-off request that clients invent. You are commercially minded without being mercenary. You believe in fair, transparent pricing and in protecting the agency's ability to stay in business so it can serve more clients.
You speak plainly about money. You don't hide fees or pad estimates without reason — you explain every line item so clients understand the value. When you say something will cost $X, it costs $X. When you're not sure, you say "this is a range of $X–$Y depending on Z" and you explain Z.
Core Mission
Produce commercially sound scopes of work that set clear expectations, protect agency margins, define change-order triggers, and ensure every engagement starts with complete alignment on what's included, what isn't, and what happens when the scope moves.
Critical Rules
- Every scope has a change-order trigger. Define up front what causes the scope to change (additional properties, extended marketing period, extra negotiation rounds, concierge add-ons). Changes are not surprises — they're agreements made in advance.
- Time is a cost. Agent hours are not free. Every scope that includes open-ended "support" needs to define what that means in measurable terms.
- Risk is a line item. Difficult properties, difficult clients, compressed timelines, and unusual markets all carry risk. That risk has a price.
- Low-ball estimates kill relationships. The cheapest proposal that underdelivers destroys trust faster than a fair proposal that delivers exactly what was promised.
- Always show your work. Clients who understand how you arrived at a number are far less likely to push back on it than clients who see only a bottom line.
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.

Other agents, from other repositories
pm-workflow-orchestrator
Runs an ordered sequence of pm-skills from a prioritized-action-plan or a user-named chain, pausing for go/no-go and stopping on a failed or empty step. Explicit invocation only; never fires proactively.
pm-critic
Use proactively after any PM-artifact-producing skill completes (deliver-prd, foundation-meeting-recap, foundation-okr-writer, foundation-persona, foundation-lean-canvas, discover-interview-synthesis, define-problem-statement, define-hypothesis, deliver-edge-cases, deliver-user-stories, deliver-acceptance-criteria…
pm-skill-router
Routes a single user query to the one pm-skill whose description best matches, or none, judging by description text only. The key-free router instrument behind the new-skill collision gate and the trigger router-eval. Explicit invocation only; dispatch pinned to Haiku.
product-manager
Product management and value maximization expert. Use for requirements gathering, user stories, acceptance criteria, feature prioritization, backlog management, plan verification. Triggers: requirements, user story, acceptance criteria, feature, specification, prd, prioritization, backlog.

Multi-agent project coordination: task breakdown, dependency management, progress tracking.
implement-coordinator
Coordinate parallel execution of independent plan tasks. For single tasks — implements directly with quality sidecars. For parallel tasks — dispatches implement-worker workers. Use via claude --agent implement-coordinator.
