What is index-manager?

A tool for building and searching indexes of documents and contract clauses. An index is a searchable catalogue that helps locate relevant records quickly.

Use it to rebuild document indexes or retrieve likely contract clauses for review, such as confidentiality clauses in non-disclosure agreements.

It narrows large document collections using contract, legal, approval, status, freshness, and clause information.

Token cost

What it costs to keep this loaded

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	$0.00970
Opus 5	$0.00000	$0.00485
Sonnet 5	$0.00000	$0.00194
Haiku 4.5	$0.00000	$0.00097

Security

Grade A, and why

index-manager 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 9d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/build-index.py, scripts/query-index.py, scripts/report-coverage.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

index-manager Skill

Manage library indexes for document and clause retrieval.

Capabilities

Index Build / Rebuild (scripts/build-index.py)
- Scans approved/ directory and rebuilds all indexes
- Usage: python3 build-index.py rebuild
- Or register a single document: python3 build-index.py register <manifest_path>
- Rebuilds: documents.json, clauses.json, terms.json, retrieval-map.json, supersession.json
Index Query (scripts/query-index.py)
- 2-stage deterministic filtering for review candidate retrieval
- Stage 1: filter by contract_family, jurisdiction, governing_law, approval_state, status
- Stage 1.5: narrow by clause_type when Stage 1 > 50 candidates
- Stage 2: exclude archived, superseded, quarantined records
- Freshness rules: downrank or exclude stale records
- Ranking honors retrieval-priority.yaml priority buckets, language preference, and affinity-family expansion
- Usage: python3 query-index.py query '{"contract_family":"nda"}'
- Token-efficient review usage: python3 query-index.py query '{"contract_family":"nda","target_clauses":[{"clause_type":"confidentiality"}],"summary_only":true,"top_k":5}'
- Hydrate selected candidates only: pass hydrate_candidate_ids:["doc_id::clause_id"]
- Search: python3 query-index.py search '{"query_text":"liability","clause_type":"limitation_of_liability"}'
- Redline patterns: python3 query-index.py redline-patterns '{"contract_family":"safe","clause_type":"indemnification"}'
Coverage Reporting (scripts/report-coverage.py)
- Summarizes configured family coverage, observed clause types, unmapped ratios, and top unmapped headings
- Usage: python3 report-coverage.py
Supersession Management (scripts/supersession.py)
- Mark documents as superseded: python3 supersession.py supersede <old_id> <new_id>
- View chain: python3 supersession.py chain <doc_id>

When to Use

After approval gate (WF1 Step 10): register new document
During review retrieval (WF2 Step 5): query candidates
During taxonomy / library audits: generate a coverage report
Library management commands: list, search, rebuild
When superseding documents

Files

What ships with it

4 files 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.

Changes

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.

index-manager is a skill published in the GitHub repository lowtidebuild/contract-review (40 stars, last pushed 1mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 970 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.
