13-13: Replace deprecated SqliteMemoryStore with AsyncSqliteMemoryStore.The pipeline failures indicate that
SqliteMemoryStoreis deprecated and blocks the async runtime. This is critical for proper async operation.Replace all instances of
SqliteMemoryStorewithAsyncSqliteMemoryStore:-use fluent_agent::memory::SqliteMemoryStore; +use fluent_agent::memory::AsyncSqliteMemoryStore; -let memory_system = Arc::new(SqliteMemoryStore::new(":memory:")?); +let memory_system = Arc::new(AsyncSqliteMemoryStore::new(":memory:").await?); -let memory = std::sync::Arc::new(SqliteMemoryStore::new(&memory_path)?); +let memory = std::sync::Arc::new(AsyncSqliteMemoryStore::new(&memory_path).await?);Note: This will require adding
.awaitto the async constructor calls and ensuring the calling functions are properly async.Also applies to: 23-23, 73-73, 91-91
tests/e2e_cli_tests.rs (1)
1-208: Significant reduction in test coverage needs justification.The test suite has been dramatically simplified, removing comprehensive async tests, detailed workflow tests, and configuration tests. While the tests are now simpler, this represents a major reduction in coverage that could allow regressions to slip through.
Additionally, there are no tests for:
- The new TLS configuration support in Neo4j
- The new MCP client/server functionality
- The engine list/test subcommands
- Enhanced security validation in commands
Consider adding at least basic tests for these new features to ensure they work as expected.

595-641: Fix the ambiguous numeric type error.The pipeline failure is due to ambiguous numeric types when parsing memory values. The
parse()calls need explicit type annotations.Apply this fix to resolve the compilation error:
for line in meminfo.lines() { if line.starts_with("MemTotal:") { if let Some(kb_str) = line.split_whitespace().nth(1) { - total_kb = kb_str.parse().unwrap_or(0); + total_kb = kb_str.parse::<u64>().unwrap_or(0); } } else if line.starts_with("MemAvailable:") { if let Some(kb_str) = line.split_whitespace().nth(1) { - available_kb = kb_str.parse().unwrap_or(0); + available_kb = kb_str.parse::<u64>().unwrap_or(0); } } else if line.starts_with("MemFree:") { if let Some(kb_str) = line.split_whitespace().nth(1) { - free_kb = kb_str.parse().unwrap_or(0); + free_kb = kb_str.parse::<u64>().unwrap_or(0); } } else if line.starts_with("Buffers:") { if let Some(kb_str) = line.split_whitespace().nth(1) { - buffers_kb = kb_str.parse().unwrap_or(0); + buffers_kb = kb_str.parse::<u64>().unwrap_or(0); } } else if line.starts_with("Cached:") { if let Some(kb_str) = line.split_whitespace().nth(1) { - cached_kb = kb_str.parse().unwrap_or(0); + cached_kb = kb_str.parse::<u64>().unwrap_or(0); } } }
571-672: Fix all parse() calls to specify explicit types.Similar ambiguous type issues exist in other platform-specific functions. All
parse()calls should specify the target type.Also apply these fixes:
In
get_memory_info_linux():if let Some(kb_str) = line.split_whitespace().nth(1) { - rss_kb = kb_str.parse().unwrap_or(0); + rss_kb = kb_str.parse::<u64>().unwrap_or(0); } } else if line.starts_with("VmSize:") { if let Some(kb_str) = line.split_whitespace().nth(1) { - virtual_kb = kb_str.parse().unwrap_or(0); + virtual_kb = kb_str.parse::<u64>().unwrap_or(0); }In
get_memory_info_macos():if parts.len() >= 2 { - let rss_kb = parts[0].parse().unwrap_or(0); - let virtual_kb = parts[1].parse().unwrap_or(0); + let rss_kb = parts[0].parse::<u64>().unwrap_or(0); + let virtual_kb = parts[1].parse::<u64>().unwrap_or(0); return Ok(MemoryInfo { rss_kb, virtual_kb });
🧹 Nitpick comments (5)
crates/fluent-agent/src/lib.rs (1)
152-164: Complete the custom allowed commands implementationThe TODO indicates that parsing custom commands from the environment variable is not yet implemented. This leaves the feature incomplete.
Would you like me to help implement the dynamic command parsing with proper lifetime management? One approach could be to use a static
OnceCellor return an ownedVec<String>instead ofVec<&'static str>.Example approach:
use once_cell::sync::Lazy; static CUSTOM_COMMANDS: Lazy<Option<Vec<String>>> = Lazy::new(|| { std::env::var("FLUENT_ALLOWED_COMMANDS") .ok() .map(|s| s.split(',').map(|cmd| cmd.trim().to_string()).collect()) }); fn get_allowed_commands() -> Vec<String> { if let Some(ref custom) = *CUSTOM_COMMANDS { custom.clone() } else { vec![ "cargo", "rustc", "git", "ls", "cat", "echo", "pwd", "which", "find" ].into_iter().map(String::from).collect() } }crates/fluent-cli/src/commands/engine.rs (2)
164-170: Extract duplicated URL construction logic.The URL construction logic is duplicated between the JSON and human-readable output paths. Consider extracting it to a helper method.
Add a helper method to construct the engine URL:
+ /// Construct URL from engine connection details + fn construct_engine_url(engine: &fluent_core::config::EngineConfig) -> String { + format!("{}://{}:{}{}", + engine.connection.protocol, + engine.connection.hostname, + engine.connection.port, + engine.connection.request_path + ) + }Then use it in both places:
- let url = format!("{}://{}:{}{}", - engine.connection.protocol, - engine.connection.hostname, - engine.connection.port, - engine.connection.request_path - ); + let url = Self::construct_engine_url(engine);Also applies to: 194-199
230-237: Implement actual connectivity test for engines.The current implementation only verifies that the engine can be instantiated, not that it can actually connect and respond. The TODO comment indicates this needs to be implemented.
Would you like me to help implement the actual connectivity test by making a simple request to verify the engine is reachable and responsive?
crates/fluent-cli/src/memory.rs (2)
15-23: Consider simplifying the cleanup counter implementation.The thread-local cleanup counter adds complexity without providing significant value. Since it's only used for debug logging and resets with each thread, consider using a simpler approach or removing it entirely.
- // Clear thread-local storage - std::thread_local! { - static CLEANUP_COUNTER: std::cell::RefCell<u64> = std::cell::RefCell::new(0); - } - - CLEANUP_COUNTER.with(|counter| { - let mut count = counter.borrow_mut(); - *count += 1; - debug!("Memory cleanup iteration: {}", *count); - }); + // Log cleanup operation + debug!("Performing memory cleanup iteration");
59-73: Memory compaction approach may be ineffective.Creating and dropping small allocations is unlikely to trigger meaningful memory compaction in modern allocators. Consider removing this method or documenting it as a best-effort attempt that may not have measurable impact.
Modern memory allocators (jemalloc, tcmalloc, etc.) handle fragmentation automatically. If memory fragmentation is a concern, consider using allocator-specific APIs or configuring the allocator appropriately instead.

🔇 Additional comments (23)
crates/fluent-agent/src/action.rs (1)
3-3: Excellent logging standardization with clear documentation.The transition from
println!toinfo!for agent communication is appropriate, and the added comment clearly explains the purpose of the change.Also applies to: 625-626
crates/fluent-agent/src/performance/utils.rs (3)
1-1: LGTM! Good addition of structured logging imports.The import of
log::{debug, info}properly supports the logging standardization across the codebase.
222-232: Excellent logging level choices for performance test output.The use of
info!for test start anddebug!for progress updates follows best practices - progress messages will only appear with debug logging enabled, reducing noise in production logs.
318-326: Well-structured summary logging with appropriate levels.Converting summary output to
info!level provides structured logging while maintaining visibility of test results. The choice to keep the final two lines asprintln!(lines 327-331) ensures critical summary information remains visible regardless of log level configuration.crates/fluent-core/tests/config_tests.rs (1)
96-96: Proper test update for Neo4j TLS configuration support.Adding
tls: Nonecorrectly maintains test compatibility with the new optional TLS field inNeo4jConfig. This follows the expected pattern for backward-compatible configuration extensions.src/main.rs (1)
4-6: Clean transition to modular CLI architecture.The direct call to
fluent_cli::cli::run_modular().awaitproperly leverages the new modular CLI implementation. The added comment clearly documents the architectural change, and the async pattern remains consistent.crates/fluent-engines/src/openai_streaming.rs (1)
305-305: Good documentation update for async best practices.The comment correction from synchronous to asynchronous stdout flushing properly guides developers toward correct async I/O patterns. This aligns with the broader shift to asynchronous programming mentioned in the PR summary.
crates/fluent-engines/src/pipeline_executor.rs (1)
528-531: LGTM! Proper async I/O conversion.The conversion from synchronous
std::io::stdin().read_line()to asynchronous Tokio I/O primitives is correctly implemented. The use oftokio::io::stdin()withBufReaderandAsyncBufReadExt::read_line().awaitfollows Tokio best practices and aligns with the broader async I/O conversion effort across the codebase.crates/fluent-cli/src/mcp_runner.rs (2)
47-47: Good clarification comment.The comment clarifying that config loading is handled by
fluent_core::config::load_configimproves code readability and removes confusion about where configuration loading occurs.
94-94: Correct mutability tightening.Changing the
agentvariable from mutable to immutable is appropriate since the variable is not modified after initialization.crates/fluent-agent/src/mcp_adapter.rs (1)
367-367: Excellent async file I/O conversion.The replacement of synchronous
std::fsoperations withtokio::fsasync equivalents is correctly implemented. The use of.awaitand error handling maintains the same logic while enabling non-blocking file operations within the async MCP adapter context.Also applies to: 378-378
crates/fluent-cli/src/commands/agent.rs (2)
4-4: Proper async I/O imports.The addition of
tokio::io::{AsyncBufReadExt, AsyncWriteExt, BufReader}imports provides the necessary traits and types for the async I/O conversion in the interactive agent loop.
196-206: Excellent async I/O conversion for interactive loop.The conversion of the interactive agent command loop to async I/O is well-implemented:
- Proper setup of async stdin reader with
BufReader::new(tokio::io::stdin())- Correct async stdout operations with
write_all()andflush().await- Appropriate use of
read_line().awaitfor non-blocking user input- Maintains the same interactive behavior while being compatible with the async command handler context
This change aligns perfectly with the broader async I/O conversion effort across the CLI subsystem.
crates/fluent-cli/src/lib.rs (2)
53-53: Good module organization.Moving the
climodule declaration earlier in the file improves the logical organization of modules within the library structure.
80-80: Clear documentation of architectural change.The comment accurately reflects the CLI refactoring where functionality has been relocated to
main.rsas part of the modularization effort described in the PR objectives.crates/fluent-core/src/config.rs (1)
35-61: Well-structured TLS configuration implementationThe TLS configuration is comprehensive and well-designed:
- Covers all common TLS scenarios (system CA, custom CA, mutual TLS)
- Sensible secure defaults (TLS disabled, certificate verification enabled)
- Clear trust strategy options
- Proper use of
Optiontypes for optional fieldsexample_configurations/example_neo4j_tls_secure.json (1)
1-96: Excellent example configurations for TLS scenariosThe example file effectively demonstrates three common TLS configuration scenarios:
- Production setup with system CA trust (
neo4j_secure)- Enterprise setup with custom CA and mutual TLS (
neo4j_custom_ca)- Development setup without TLS (
neo4j_development)Good security practices with AMBER variables for sensitive data.
crates/fluent-core/src/neo4j_client.rs (1)
84-95: Good separation of concerns in the constructor.The refactoring to separate ConfigBuilder construction from the build step is a clean approach that allows for conditional TLS configuration.
crates/fluent-cli/src/cli.rs (1)
20-77: Excellent modular refactor of the CLI.The transformation from a monolithic CLI to a modular dispatcher is well-executed. The code is now much cleaner with clear separation of concerns. The graceful handling of missing config files (lines 36-41) is a good improvement for user experience.
crates/fluent-cli/src/cli_builder.rs (1)
20-21: Config file extension validated as .tomlNo occurrences of
fluent_config.yamlor.ymlwere found in the codebase. The default value
incrates/fluent-cli/src/cli_builder.rs(lines 20–21).default_value("fluent_config.toml") .global(true),is consistent.
crates/fluent-cli/src/memory.rs (3)
91-255: Well-implemented resource cleanup methods.The cleanup methods for temporary resources, checkpoints, cache files, and log files are well-designed:
- Proper error handling with logging
- Appropriate retention policies (7 days for checkpoints, 1 day for cache)
- Smart decision to truncate rather than delete log files
- Good use of platform-specific temp directories
374-504: Excellent ResourceGuard implementation.The enhanced ResourceGuard provides comprehensive resource management:
- Multiple resource types tracked (files, dirs, memory, callbacks)
- Proper cleanup order in
perform_cleanup- Good error handling with logging
- Correct Drop implementation
714-797: Comprehensive test coverage.The tests effectively cover the main functionality:
- Memory manager operations
- Resource guard cleanup including enhanced features
- Proper use of tempfile for test isolation

Dangerous patterns list differs from tools/mod.rs
The dangerous patterns list here is much shorter than the comprehensive list in tools/mod.rs. This inconsistency could lead to security gaps where commands blocked in one module are allowed in another.
Consider extracting the dangerous patterns to a shared constant or module to ensure consistency across the codebase:
// In a shared module like crates/fluent-agent/src/security/patterns.rs
pub const DANGEROUS_PATTERNS: &[&str] = &[
// Command injection patterns
"$(", "`", ";", "&&", "||", "|", ">", ">>", "<", "<<",
// Path traversal

// ... rest of the comprehensive list from tools/mod.rs

In crates/fluent-agent/src/lib.rs around lines 128 to 133, the list of dangerous
patterns used to validate commands is shorter and inconsistent compared to the
comprehensive list in tools/mod.rs, which risks security gaps. To fix this,
extract the dangerous patterns into a shared constant or module (e.g.,
crates/fluent-agent/src/security/patterns.rs) containing the full list from
tools/mod.rs, then import and use this shared constant in lib.rs to ensure
consistent validation across the codebase.

Implement dynamic command whitelist parsing in output_processor
The get_command_whitelist function currently logs the FLUENT_ALLOWED_COMMANDS env var but always falls back to the default static list (see the TODO in crates/fluent-core/src/output_processor.rs). A similar TODO exists in crates/fluent-agent/src/lib.rs. Please:
- Parse the comma-separated
custom_commandsstring into an owned collection (e.g.Vec<String>) rather than returning&'static str. - Trim, validate, and sanitize each command entry.
- Update the function signature to return the owned collection.
- Remove the TODO once implemented and add tests covering both default and custom-whitelist paths.

change the function to return an owned collection like Vec<String> instead of

collect them into the Vec<String>. If the environment variable is not set or
invalid, return the default command list as owned Strings. Remove the TODO

Centralize Dangerous Pattern Definitions
There are now four distinct dangerous_patterns lists in the repo—two within output_processor.rs alone—leading to drift and extra upkeep:
• crates/fluent-core/src/input_validator.rs – regex-based injection checks
• crates/fluent-core/src/output_processor.rs – two separate substring-based checks in different functions
• crates/fluent-agent/src/lib.rs – minimal command-validation list
• crates/fluent-agent/src/tools/mod.rs – extended tool-invocation list
Recommend extracting a core set of patterns into a shared module or crate (e.g. fluent-security), then importing that in each location and layering on any context-specific entries. This consolidation will ensure a single source of truth and simplify future updates.

In crates/fluent-core/src/output_processor.rs around lines 417 to 430, the
dangerous_patterns list duplicates similar lists scattered across multiple files
in the repo, causing maintenance overhead. Refactor by extracting the core
dangerous patterns into a new shared module or crate (e.g., fluent-security)
that exports the base list. Then replace the local lists in output_processor.rs
and other files with imports from this shared source, adding only
context-specific patterns locally as needed. This centralization will unify
pattern definitions and reduce duplication.

🧩 Analysis chain
TLS configuration is not actually applied to the Neo4j connection.
The apply_tls_config method validates TLS settings but doesn't actually configure TLS on the ConfigBuilder. The comment on lines 183-185 indicates this is a placeholder implementation. This means TLS won't be enabled even if configured, which could be a security issue if users expect TLS to be working.
Either implement the actual TLS configuration or clearly document that TLS is not yet supported.
🌐 Web query:
Does the neo4rs ConfigBuilder support TLS configuration methods? What are the available TLS configuration options in the latest neo4rs version?
💡 Result:
The neo4rs Rust driver’s ConfigBuilder does support TLS configuration methods in its latest versions. Here are the supported TLS (SSL) configuration options according to the most recent API documentation:
- with_client_certificate:
Allows you to specify a client certificate for mutual TLS authentication. This enables you to provide a path to a certificate file using the builder method:ConfigBuilder::default() .with_client_certificate("/path/to/client_cert.pem") // other config options... .build()
- skip_ssl_validation:
As of version 0.8.0, askip_ssl_validationflag has been introduced, enabling you to instruct the driver to bypass server certificate validation—useful for development and testing environments with self-signed certificates[5]. - URI scheme configuration:
By using aneo4j+sscconnection scheme in your.uri()method, the driver is instructed to accept self-signed certificates without validation[5]. - System certificates:
By default, the driver uses system-installed certificates for server validation unless otherwise configured[5].
Here’s a summary table of the TLS-related options currently available via ConfigBuilder:
| Option/Method | Description |
|---|---|
| with_client_certificate(path) | Specifies client certificate for mutual TLS. |
| skip_ssl_validation(bool) | Skips server certificate validation (should be used with caution). |
| .uri("neo4j+ssc://…") | Accepts self-signed certificates by using custom scheme. |
| System CA store | Used by default for SSL/TLS validation unless overridden. |
You can find these methods in the latest [API documentation][9] and the changelog for recent releases[5].
The following methods are available in ConfigBuilder for TLS configuration:
with_client_certificate,skip_ssl_validation, and automatic support for system certificates.
— Source: [neo4rs Rust Docs][9], [neo4rs GitHub Releases][5]
Note: The primary TLS configuration entry points are with_client_certificate for client authentication, skip_ssl_validation for disabling certificate checks, and the choice of URI scheme for controlling TLS mode. The ConfigBuilder does not expose fine-grained control of protocol versions or custom trust stores—the system default is used unless overridden as above[5][9].
If you need more advanced TLS setup, such as custom root CAs or protocol version selection, it may not be directly supported in neo4rs—these are usually handled at the system/OpenSSL layer rather than by the driver itself.

Implement actual TLS configuration in apply_tls_config
The method currently only validates and logs TLS settings but never invokes any ConfigBuilder TLS APIs, so no TLS is ever enabled.
Suggested fixes in crates/fluent-core/src/neo4j_client.rs within apply_tls_config:
- Initialize a mutable builder early:
let mut builder = builder;
- For “trust_all” / disabled verification:
Some("trust_all") => { warn!("Using trust_all strategy—this bypasses certificate validation and is insecure for production"); -
debug!("Would configure trust_all strategy");
-
}
builder = builder.skip_ssl_validation(true);
- For “trust_custom_ca” (not supported by neo4rs):
Some("trust_custom_ca") => { -
if let Some(ca_path) = &tls_config.ca_cert_path { -
debug!("Using custom CA certificate from: {}", ca_path); -
// Note: Actual implementation would load and configure the CA cert -
} else { -
return Err(anyhow!("trust_custom_ca strategy requires ca_cert_path")); -
}
-
return Err(anyhow!( -
"Custom CA trust is not supported by neo4rs; use system CA or skip_ssl_validation" -
}
));
- Apply client certificates when both cert and key are provided:
// Log client certificate configuration if tls_config.client_cert_path.is_some() && tls_config.client_key_path.is_some() { debug!("Client certificate authentication will be used"); -
// Note: The actual neo4rs API calls would go here
-
builder = builder.with_client_certificate( -
tls_config.client_cert_path.as_ref().unwrap(), -
}
);
- Finally, return the updated builder:
Ok(builder)
With these changes, you’ll actually enable TLS on the Neo4j connection using the driver’s APIs.

In crates/fluent-core/src/neo4j_client.rs from lines 107 to 188, the
apply_tls_config function currently only validates and logs TLS settings without
applying them to the ConfigBuilder, so TLS is never enabled. To fix this, make
the builder mutable at the start, then use the neo4rs ConfigBuilder TLS APIs to
configure TLS based on the trust strategy: for "trust_all", disable certificate
verification; for "trust_custom_ca", load and apply the custom CA certificate;
and if both client certificate and key paths are provided, load and apply the
client certificate authentication. Finally, return the updated builder with
these TLS settings applied.

In crates/fluent-cli/src/memory.rs between lines 35 and 56, the
clear_static_caches function does not effectively clear caches because
std::env::vars().count() does not refresh environment variable caches and the
platform-specific blocks only log messages without performing any cache
clearing. To fix this, either implement actual cache clearing logic for
environment variables and DNS caches on each platform or clearly document that
this function is a placeholder for future implementation, removing ineffective
code and adding comments to indicate the current limitations.
