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 | $0.00015 | $0.05870 |
| Opus 5 | $0.00008 | $0.02935 |
| Sonnet 5 | $0.00003 | $0.01174 |
| Haiku 4.5 | $0.00002 | $0.00587 |
Grade A, and why
lavra-review 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.
How it starts
The opening of the file, as written. The whole thing — 566 lines — stays where its author put it; the contents beside it link to each section on GitHub.

#$ARGUMENTS
<project_root>
All .lavra/ paths are relative to the project root. If you cd into a subdirectory during work, resolve the project root first:
PROJECT_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || echo "$PWD")
Then prefix all .lavra/ paths with "$PROJECT_ROOT/" when invoking them via Bash.
</project_root>
1. Determine Review Target & Setup (ALWAYS FIRST)
Immediate Actions:
- Determine review type: bead ID (BD-xxx), PR number (numeric), GitHub URL, or empty (current in-progress bead)
- If bead ID provided:
bd show {BEAD_ID} --json - If no target:
bd list --status in_progress --json | jq -r '.[0].id' - Check current git branch
- If ALREADY on target branch -> proceed with analysis on current branch
- If DIFFERENT branch -> offer worktree: "Use git-worktree skill for isolated checkout." Call
skill: git-worktreewith branch name - Fetch PR metadata via
gh pr view --jsonfor title, body, files, linked issues (if PR exists) - Set up language-specific analysis tools
- Verify on the branch being reviewed
Code must be ready for analysis before proceeding.
2. Recall Relevant Knowledge
# Extract keywords from bead title/description
PROJECT_ROOT=$(git rev-parse --show-toplevel 2>/dev/null || echo "$PWD")
"$PROJECT_ROOT/.lavra/memory/recall.sh" "{keywords from bead title}"
"$PROJECT_ROOT/.lavra/memory/recall.sh" "{tech stack keywords}"
"$PROJECT_ROOT/.lavra/memory/recall.sh" --recent 10
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

lavra-review is a skill published in the GitHub repository roberto-mello/lavra (51 stars, last pushed 2mo ago), licensed MIT. It adds 15 tokens to every session and 5,870 once invoked, about $0.0001 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.
Other skills, from other repositories
fabric-spec
Starts a persistent Pi Fabric spec supervisor that audits the main session against a feature design spec and steers only when a requirement lacks verified evidence. Use for strict, unblocked spec compliance while the main agent keeps full freedom to orchestrate.
fabric-advisor
Starts a persistent Pi Fabric peer advisor that reviews the main agent at decision points and surfaces only concrete, material advice. Use for ambient correctness review without another extension.
bt6-queue-audit
Audit the full pull-request and issue queue of a BT6 research or support repository, classifying readiness, evidence risk, and next action without mutating tracker state.
bt6-pr-audit
Audit one pull request in a BT6 research or support repository at an exact head SHA, covering correctness, research integrity, security, tests, contracts, and merge readiness.
bt6-provider-review
Audit an external AI/API provider and its integration into a BT6 repository for service reality, independent verification, trust boundaries, secret handling, API/model correctness, completeness, claim traceability, and merge readiness.
ubiquitous-language
Use when evaluating the ubiquitous language in a codebase - produces a glossary of domain terms with references and commentary on inconsistencies, awkward names, or overlapping concepts.
