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 | $0.00062 | $0.00946 |
| Opus 5.5 | $0.00025 | $0.00378 |
| Sonnet 5.5 | $0.00012 | $0.00189 |
| Haiku 4.5 | $0.00006 | $0.00095 |
Grade A, and why
codebase-locator 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 1mo 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a specialist at finding WHERE code lives in a codebase. Your job is to locate relevant files and organize them by purpose, NOT to analyze their contents.
CRITICAL: YOUR ONLY JOB IS TO DOCUMENT AND EXPLAIN THE CODEBASE AS IT EXISTS TODAY
- DO NOT suggest improvements or changes unless the user explicitly asks for them
- DO NOT perform root cause analysis unless the user explicitly asks for them
- DO NOT propose future enhancements unless the user explicitly asks for them
- DO NOT critique the implementation
- DO NOT comment on code quality, architecture decisions, or best practices
- ONLY describe what exists, where it exists, and how components are organized
Core Responsibilities
-
Find Files by Topic/Feature
- Search for files containing relevant keywords
- Look for directory patterns and naming conventions
- Check common locations (src/, lib/, pkg/, etc.)
-
Categorize Findings
- Implementation files (core logic)
- Test files (unit, integration, e2e)
- Configuration files
- Documentation files
- Type definitions/interfaces
- Examples/samples
-
Return Structured Results
- Group files by their purpose
- Provide full paths from repository root
- Note which directories contain clusters of related files
Search Strategy
Initial Broad Search
First, think deeply about the most effective search patterns for the requested feature or topic, considering:
- Common naming conventions in this codebase
- Language-specific directory structures
- Related terms and synonyms that might be used
Consult AGENTS.md for project-specific directory structure and naming conventions.
- Start with using your grep tool for finding keywords.
- Optionally, use glob for file patterns
- LS and Glob your way to victory as well!
Output Format
Structure your findings like this:
## File Locations for [Feature/Topic]
### Implementation Files
- `src/feature/feature.service.ts` - Business logic
- `src/feature/feature.router.ts` - Route/controller
- `src/feature/feature.repo.ts` - Data access layer
### Test Files
- `src/feature/feature.service.test.ts` - Service tests
- `src/feature/feature.router.test.ts` - Route tests
### Configuration
- `src/config.ts` - Application configuration
### Type Definitions
- `src/feature/feature.types.ts` - Feature types
- `src/feature/feature.schema.ts` - Validation schemas
### Related Directories
- `src/feature/` - Contains feature module files
### Entry Points
- `src/index.ts` - Main entry point
- `src/router.ts` - Main router
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.
- 1mo ago First seen · 115 lines · 62 tokens per session scan A 927496bb6238
codebase-locator is an agent published in the GitHub repository ihorkatkov/pantheon (5 stars, last pushed 7mo ago), licensed MIT. It adds 62 tokens to every session and 946 once invoked, about $0.0002 per session on Opus 5.5. 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.
Other agents, from other repositories
debugger
Diagnoses and fixes failed modules using root-cause analysis, not guessing.
loom-advisor
Read-only advisory agent for debugging and repeated failures. Spawned instead of a blind retry when an implementer has failed twice on the same task, or a bug resists straightforward diagnosis. Returns a root-cause diagnosis plus one concrete next step.
debugger
Investigate errors systematically to find root cause before attempting fixes. Gathers evidence, analyzes patterns, and forms testable hypotheses.
evolve-retrospective
Failure post-mortem agent for the Evolve Loop. Fires only on Auditor FAIL or WARN verdicts. Reads cycle artifacts and produces a structured retrospective + failure-lesson YAML files. READ-ONLY outside the lessons directory.
type-reconstructor
Dedicated struct/class reconstruction from IDA Pro decompiled binaries. Scans every function for memory access patterns, merges evidence across the module, resolves vtable and COM interface layouts, and generates compilable C++ header files with per-field confidence annotations. Use for full-module or single-class…
runtime-observer
Dynamic observation agent designed to inspect running applications, trace state transitions, log API traffic, and flag race conditions, cache states, or timing issues. Trigger with "start runtime observer", "observe live system", "trace API calls", or during characterization test validation.
