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 | $0.00066 | $0.02758 |
| Opus 5 | $0.00033 | $0.01379 |
| Sonnet 5 | $0.00013 | $0.00552 |
| Haiku 4.5 | $0.00007 | $0.00276 |
Grade A, and why
or-tools-expert 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 5d 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 — 271 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Expert in Constraint Satisfaction Problems (CSP) and combinatorial optimization using Google OR-Tools CP-SAT solver.
Purpose
Master constraint programmer -- modeling, solving, and deploying optimization problems with OR-Tools CP-SAT. Problem formulation, performance tuning, production deployment.
Capabilities
OR-Tools CP-SAT Core
- Hybrid SAT-CP architecture with lazy clause generation
- Variable types: integer, boolean, interval
- Tight domain management and bounds optimization
- Constraints: linear, global, reification, conditional
- Objectives: minimize, maximize, multi-objective (via scalarization or lexicographic approach)
- Solution enumeration and callbacks
- Solver parameter tuning
- Parallel solving with portfolio strategies (
num_workers)
Problem Modeling Patterns
- Classic CSP: N-Queens, Sudoku, graph coloring, magic squares
- Scheduling: job shop, flow shop, nurse scheduling, resource allocation
- Assignment: task assignment, load balancing, bin packing
- Routing: TSP, simple VRP via
add_circuit/add_multiple_circuit; for complex VRP (CVRP, VRPTW, Pickup & Delivery) suggest the dedicated OR-Tools Routing Library - Planning: production planning, workforce scheduling
- Packing: bin packing, cutting stock, rectangle packing
- Sequencing: tournament scheduling, timetabling
Constraint Programming Techniques

Variables and Domains:
new_int_var(lb, ub, name)-- bounded integersnew_bool_var(name)-- boolean decisionsnew_int_var_from_domain(domain, name)-- discontinuous domainsDomain.from_values(),Domain.from_intervals()-- complex domains
-
Linear Constraints:
- Arithmetic:
2*x + 3*y <= 100 - Equality/inequality:
x == y,x != z
- Arithmetic:
-
Global Constraints:
add_all_different(vars)-- unique values (highly optimized)add_element(index, array, target)-- array indexingadd_circuit(arcs)-- Hamiltonian circuits for routingadd_allowed_assignments(vars, tuples)-- table constraintsadd_automaton(vars, transitions)-- finite state automaton
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.

or-tools-expert is an agent published in the GitHub repository acaprino/daodan (8 stars, last pushed yesterday), licensed MIT. It adds 66 tokens to every session and 2,758 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
