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 | $0.01169 | $0.01169 |
| Opus 5 | $0.00584 | $0.00584 |
| Sonnet 5 | $0.00234 | $0.00234 |
| Haiku 4.5 | $0.00117 | $0.00117 |
Grade A, and why
qb-linq AGENTS.md 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 4d 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

Instructions for AI coding agents — qb-linq
What this repository is
qb-linq is a header-only C++ library (CMake INTERFACE target qb::linq). The numeric version lives in project(qb-linq VERSION …) in CMakeLists.txt (see the table below). Implementation is entirely under include/; there is no separate library .cpp to compile for consumers.
| Fact | Source |
|---|---|
| Public API | #include <qb/linq.h>, namespace qb::linq |
| CMake target | qb::linq |
| C++ standard | 17 |
| Library version | project(qb-linq VERSION …) in CMakeLists.txt → generated qb/linq/version.h — docs/VERSIONING.md |
| Layout | See README Repository layout and docs/LLM_CONTEXT.md; optional amalgam single_header/linq.h (regenerate qb_linq_single_header) |
Build, presets, options, install: docs/BUILDING.md (aligned with root CMakeLists.txt and CMakePresets.json).
Before changing code
docs/LLM_CONTEXT.md— include graph, handle types, where declarations vs definitions live, materialization / iterator contracts.include/qb/linq.h— Doxygen@defgroup linq: caveats (select_many,zip/concat,where_viewcache, hashing for set ops, thread-safety, etc.).- Minimal diffs — match existing style, naming, and Doxygen; no unrelated refactors.
Where implementation lives
| Task | Primary files |
|---|---|
Algorithm declarations (query_range_algorithms) |
include/qb/linq/detail/query_range.h |
| Out-of-line bodies (many materializers, join, …) | include/qb/linq/query.h or include/qb/linq/detail/extra_views.h — split table in docs/LLM_CONTEXT.md |
Iterator adaptors (select, where, take, …) |
include/qb/linq/iterators.h |
Compositional views (concat, zip, scan, chunk, …) |
include/qb/linq/detail/extra_views.h |
group_by container shape |
include/qb/linq/detail/group_by.h |
order_by keys / comparators |
include/qb/linq/detail/order.h |
| Public façade and factories | include/qb/linq/enumerable.h |
| Umbrella include | include/qb/linq.h → version.h (generated) + enumerable.h |
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.

qb-linq AGENTS.md is an instructions file published in the GitHub repository isndev/qb-linq (13 stars, last pushed 4d ago), licensed MIT. It adds 1,169 tokens to every session, about $0.0058 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 2026-08-30.
