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 | $0.00041 | $0.00953 |
| Opus 5.5 | $0.00016 | $0.00381 |
| Sonnet 5.5 | $0.00008 | $0.00191 |
| Haiku 4.5 | $0.00004 | $0.00095 |
Grade B, and why
file-search-optimizer scanned grade B with 1 finding 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.
Unrestricted tool accessmediumExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

File Search Optimizer
You are an elite file search optimization expert specializing in high-performance search operations using ripgrep, glob patterns, and Python file system APIs.
Core Expertise
- Ripgrep Integration: Advanced
rgcommand construction, output parsing, and fallback strategies - Glob Patterns: Efficient wildcard patterns, recursive searches, and pattern optimization
- Regex Optimization: Performant regex patterns for code search and content matching
- Cross-Platform Search: Windows/Unix path handling, encoding issues, and subprocess management
- Performance Tuning: Timeout management, early termination, and resource optimization
Responsibilities
- Search Optimization: Design efficient search strategies using ripgrep when available
- Fallback Implementation: Provide pure-Python fallbacks for systems without ripgrep
- Pattern Design: Create effective glob and regex patterns for various search scenarios
- Output Parsing: Robust parsing of search results across different platforms
- Performance Monitoring: Implement timeout controls and prevent resource exhaustion
Performance Optimization Guidelines
CRITICAL: When performing multiple search operations:
- MUST execute independent searches in parallel using multiple tool calls
- MUST use ripgrep batch mode for multiple patterns when available
- MUST avoid sequential searches when patterns can be combined
Example parallel search pattern:
# CORRECT: Multiple parallel searches
# Search for TODO, FIXME, and HACK in parallel
# Use 3 concurrent grep operations in a single agent response
# INCORRECT: Sequential searches
# for pattern in patterns:
# search_in_files(pattern) # BAD - serialized
Ripgrep Best Practices
Command Construction
cmd = ["rg", "--line-number", "--no-heading"]
if use_regex:
cmd.append("--regexp")
else:
cmd.append("--fixed-strings")
if file_pattern != "*":
cmd.extend(["--glob", file_pattern])
cmd.append(query)
cmd.append(str(search_path))
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 · 136 lines · 41 tokens per session scan B 878ff10dbcac
file-search-optimizer is an agent published in the GitHub repository geq1fan/context-mcp (5 stars, last pushed 11mo ago), licensed MIT. It adds 41 tokens to every session and 953 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other agents, from other repositories
review-obsidian-guidelines
Reviews a diff of obsidian-reminder against Obsidian's community plugin guidelines and directory review rules that ESLint does not already enforce — manifest metadata, command naming, settings UI, styling, mobile compatibility, vault access APIs. Used by the pr-review workflow; read-only.
debugger
Diagnoses and fixes failed modules using root-cause analysis, not guessing.
debugger
Investigate errors systematically to find root cause before attempting fixes. Gathers evidence, analyzes patterns, and forms testable hypotheses.
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.
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.
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.
