Review feedback 2 #43

Description

@pardeike

This is feedback from an AI code review. Some topics might be too nitpicking or abstract and offer no real value. You decide which are worth to address:

  1. Port selection may yield negative or invalid values
    randomInt builds a signed int from raw bytes without error handling; findAvailablePort then uses that value modulo the port range, which can produce negative results and ignore read errors
    Suggested task
    Use secure, non-negative port generation

  2. Connection backoff jitter is deterministic
    rand.Float64() from the global math/rand source is used without seeding, causing identical retry patterns across runs
    Suggested task
    Seed or replace PRNG for backoff jitter

  3. Handshake reports a hard-coded bridge version
    BridgeVersion is fixed to "1.0.0" instead of the runtime version, risking mismatch with built binaries
    Suggested task
    Report actual build version in handshake

  4. GetGame returns a pointer to a copy
    The method returns a pointer to a copy of the map value, so any mutations won’t persist in the configuration map
    Suggested task
    Return configuration data without losing map linkage

  5. Backoff parser lacks range validation
    parseBackoff accepts any order of durations, so “5s..100ms” silently flips the window and yields unexpected delays
    Suggested task
    Validate backoff range order

  6. Resource handlers ignore JSON marshaling errors
    Each resource handler discards potential json.Marshal failures, which could mask serialization problems
    Suggested task
    Propagate marshal errors in resource handlers

  7. Tool results lose structure when not plain text
    When a GABP tool result lacks a "text" field, it’s formatted with %v, producing Go’s map representation rather than JSON
    Suggested task
    Serialize non-text tool results as JSON

  8. Process lookup may match unintended names
    Linux process discovery treats any substring or suffix match as valid, risking accidental termination of unrelated processes
    Suggested task
    Tighten process name matching
