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 | $0.00069 | $0.03560 |
| Opus 5 | $0.00034 | $0.01780 |
| Sonnet 5 | $0.00014 | $0.00712 |
| Haiku 4.5 | $0.00007 | $0.00356 |
Grade C, and why
th0th-memory scanned grade C with 2 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 4d 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.

th0th-memory Skill
Mandatory rules for using th0th tools. Prioritize semantic search, compression, memory, and symbol graph tools over native tools (Glob, Grep, Read) to explore and understand code.
When to Apply
Reference these guidelines when:
- Searching for code patterns or implementations
- Navigating to symbol definitions or finding all usages of a symbol
- Understanding codebase architecture
- Storing important decisions or patterns
- Compressing large code contexts
- Retrieving memories from previous sessions
- Listing or checking the status of indexed projects
- Analyzing usage and performance metrics
Available Tools
| Priority | Tool | Use |
|---|---|---|
| 1 | th0th_index |
Index project before searching (returns jobId for background jobs) |
| 2 | th0th_index_status |
Poll background indexing job status by jobId |
| 3 | th0th_search |
Semantic + keyword search with filters |
| 4 | th0th_optimized_context |
Search + compress in one call (max token efficiency) |
| 5 | th0th_search_definitions |
Find symbol definitions (functions, classes, types) |
| 6 | th0th_get_references |
Find all usages of a symbol across the project |
| 7 | th0th_go_to_definition |
Jump to a symbol's definition with context |
| 8 | th0th_list_projects |
List all indexed projects and their status |
| 9 | th0th_reset_project |
Delete all indexed data for a project (vectors, symbols, memories) |
| 10 | th0th_remember |
Store important information in persistent memory |
| 11 | th0th_recall |
Retrieve memories from previous sessions |
| 12 | th0th_compress |
Reduce context size (70-98%) |
| 13 | th0th_analytics |
Usage patterns and metrics |
| 14 | th0th_read_file |
Read file/line-range with symbol metadata (prefer over Read when you have lineStart/lineEnd) |
| 15 | th0th_project_map |
One-shot project overview: PageRank backbone, symbol counts, language distribution |
| 16 | th0th_synapse_session |
Create/resume Synapse cognitive session (task alignment, agent affinity, working memory) |
| 17 | th0th_synapse_prime |
Seed Synapse buffer with recalled memories before searching |
| 18 | th0th_synapse_access |
Record file access for affinity scoring (call after reading/editing a file) |
| 19 | th0th_symbol_snippet |
Get raw code snippet by file + line range |
| 20 | th0th_memory_list |
Browse memories by type/importance without a query (audit mode) |
| 21 | th0th_reindex |
Force full reindex (when autoReindex/50-file limit is insufficient) |
| 22 | Glob/Grep/Read | Only when th0th doesn't find what you need |
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.
- 4d ago First seen · 400 lines · 69 tokens per session scan C 8bf2de91e182
th0th-memory is a skill published in the GitHub repository S1LV4/th0th (135 stars, last pushed 2mo ago), licensed MIT. It adds 69 tokens to every session and 3,560 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
