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 | $0.00000 | $0.01589 |
| Opus 5 | $0.00000 | $0.00794 |
| Sonnet 5 | $0.00000 | $0.00318 |
| Haiku 4.5 | $0.00000 | $0.00159 |
Grade A, and why
update_blas_lapack 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 6d 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.

Update BLAS/LAPACK Skill to Latest Library Version
This command updates the LAPACK library to the latest version and synchronizes all skill files with the updated CBLAS and LAPACKE APIs.
Working directory: plugins/blas_lapack/
Repository Structure
plugins/blas_lapack/
├── skills/blas_lapack/ # Skill content (SKILL.md and references/)
├── lapack/ # Upstream repo clone (NOT a submodule)
└── .claude-plugin/plugin.json # Plugin manifest
The lapack/ directory is a standalone git clone from https://github.com/Reference-LAPACK/lapack - updated independently via git fetch and git checkout <tag>.
Process
1. Update LAPACK Library to Latest Tag
cd plugins/blas_lapack/lapack
# Fetch all tags from upstream
git fetch --tags
# Check current version
CURRENT_TAG=$(git describe --tags --abbrev=0 2>/dev/null || echo "unknown")
echo "Current tag: $CURRENT_TAG"
# Get latest v3.x.y tag (stable releases use v#.#.# format)
LATEST_TAG=$(git tag --sort=-v:refname | grep "^v[0-9]" | head -n 1)
echo "Latest tag: $LATEST_TAG"
# Preview changes between versions
if [ "$CURRENT_TAG" != "unknown" ] && [ "$CURRENT_TAG" != "$LATEST_TAG" ]; then
echo "Commits between $CURRENT_TAG and $LATEST_TAG:"
git log --oneline "$CURRENT_TAG..$LATEST_TAG" | head -n 50
# Look for API-related changes
echo -e "\nAPI-related commits:"
git log --oneline "$CURRENT_TAG..$LATEST_TAG" --grep="LAPACKE\|CBLAS\|deprecat\|new routine" -i
fi
# Checkout latest tag
git checkout "$LATEST_TAG"
# Verify
echo "Now on: $(git describe --tags)"
cd ..
- Latest tags viewable at: https://github.com/Reference-LAPACK/lapack/tags
- Stable release tags use format:
v3.X.Y(e.g.,v3.12.0,v3.12.1)
2–6. Analyze & Update Documentation (subagent)
Dispatch a general-purpose subagent via the Task tool for the analysis and
documentation rewrite. This keeps the large header content out of the main context.
Provide the subagent with:
- Path to CBLAS header:
plugins/blas_lapack/lapack/CBLAS/include/cblas.h - Path to LAPACKE header:
plugins/blas_lapack/lapack/LAPACKE/include/lapacke.h - Path to skill references:
plugins/blas_lapack/skills/blas_lapack/references/ - Old tag and new tag (from Step 1 output)
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.

update_blas_lapack is a command published in the GitHub repository datathings/marketplace (11 stars, last pushed 9d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,589 tokens. 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.

Batch-lift all methods of a C++ class with shared type context, producing a single cohesive .cpp output file with struct definitions, constants, and all methods in dependency order. Uses assembly as ground truth to ensure 100% functional equivalence.
reconstruct-types
Reconstruct C/C++ struct and class definitions from a module's decompiled code by scanning memory access patterns, vtable contexts, and mangled names across all functions. Generates compilable C++ header files with per-field confidence annotations.
