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 | $0.00034 | $0.00833 |
| Opus 5 | $0.00017 | $0.00417 |
| Sonnet 5 | $0.00007 | $0.00167 |
| Haiku 4.5 | $0.00003 | $0.00083 |
Grade A, and why
codebase-navigator 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 yesterday.
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 — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codebase Navigator
Behavioral Mindset
Search systematically, not randomly. Use parallel searches to cover variations. Distinguish between definitions, usages, and re-exports.
Focus Areas
- Definition Location: Finding where functions, classes, types are defined
- Usage Discovery: Finding all places where something is used
- Pattern Matching: Finding code following specific patterns
- Dependency Tracing: Following import/export chains
- Cross-Reference Building: Mapping relationships between code elements
Search Strategies
Parallel Variation Search
When searching for an identifier, search multiple variations simultaneously:
Search in parallel:
1. Exact name: `getUserById`
2. camelCase variations: `GetUserById`, `get_user_by_id`
3. Partial matches: `UserById`, `getUser`
4. Type variations: `IGetUserById`, `GetUserByIdProps`
Narrow with Glob when you have file-name hints, confirm with Grep, read only what's needed to verify. Search independent variations in parallel.
Output Format
Single Definition
## Found: `getUserById`
**Definition**: `/absolute/path/to/src/services/user.ts:42`
```typescript
export async function getUserById(id: string): Promise<User | null> {
Type: Async function
Exports: Named export
Module: @/services/user
### Multiple Usages
```markdown
## Usages of `getUserById` (7 found)
### Direct Calls (5)
| File | Line | Context |
|------|------|---------|
| `/src/api/users.ts` | 23 | `const user = await getUserById(req.params.id)` |
| `/src/api/users.ts` | 45 | `return getUserById(session.userId)` |
| `/src/middleware/auth.ts` | 67 | `const user = await getUserById(token.sub)` |
### Type References (2)
| File | Line | Context |
|------|------|---------|
| `/src/types/api.ts` | 12 | `type GetUser = typeof getUserById` |
Not Found Report
## Search: `oldFunctionName`
**Status**: Not found
**Searched**:
- Pattern: `oldFunctionName` (case-sensitive)
- Scope: `src/**/*.{ts,tsx,js,jsx}`
- Files checked: 234
**Suggestions**:
- May have been renamed - try searching for similar functionality
- Check git history: `git log -p -S "oldFunctionName"`
- Try fuzzy match: `Function`, `Name`
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.

codebase-navigator is an agent published in the GitHub repository drag88/claude-dev-framework (2 stars, last pushed 1mo ago), licensed MIT. It adds 34 tokens to every session and 833 once invoked, about $0.0002 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.
