* feat(skills): add retry mechanism for HTTP requests
Implement a retry mechanism with exponential backoff for HTTP requests in the skill installer. This improves reliability when fetching skills from GitHub by automatically retrying failed requests up to 3 times.
Add comprehensive tests to verify retry behavior under different scenarios including success on different attempts and proper delay between retries.
* fix: improve http request retry logic with status code checks
Add shouldRetry helper function to determine retryable status codes.
Close response body between retry attempts and break early for non-retryable status codes.
* refactor: remove unused BuiltinSkill struct
The struct was not being used anywhere in the codebase, so it's safe to remove it to reduce clutter and improve maintainability.
* refactor(http): move retry logic to utils package
Extract HTTP retry functionality from skills package to utils for better reusability
Add context-aware sleep function and comprehensive tests
* refactor(http): extract retry delay unit to variable
Extract hardcoded retry delay unit to a variable for better testability and flexibility. Update tests to use milliseconds for faster execution while maintaining the same behavior.
* test(http_retry): remove t.Parallel from test cases
* test(http_retry): remove redundant test cases for retry success
The removed test cases for success on second and third attempts were redundant since the retry logic is already covered by other tests. This simplifies the test suite while maintaining coverage.
Change the default value of session.dm_scope from "main" to
"per-channel-peer" to provide better conversation isolation by
default. This prevents context leakage between different users
and channels.
* fix: remove redundant tools definitions from system prompt
Tools are already provided to the LLM via JSON schema through
ToProviderDefs(), so the text-based tools section in the system
prompt is redundant.
This removes the buildToolsSection() logic and the tools field
from ContextBuilder, reducing system prompt length while maintaining
the "ALWAYS use tools" rule reminder.

Whitespace is a linter that checks for unnecessary newlines at the start and end of functions, if, for, etc.

Avoid rebuilding the entire system prompt on every BuildMessages() call
by caching the static portion (identity, bootstrap, skills summary,
memory) and only recomputing it when workspace source files change.
Key changes:
- ContextBuilder caches the static prompt behind an RWMutex with
double-checked locking. Source file changes are detected via cheap
os.Stat mtime checks so no explicit invalidation is needed.
- Track file existence at cache time (existedAtCache map) so that
newly created or deleted bootstrap/memory files also trigger a
rebuild — the old modifiedSince() silently returned false on
os.IsNotExist.
- Walk the skills directory recursively with filepath.WalkDir to
catch content-only edits at any nesting depth; directory mtime
alone misses in-place file modifications on most filesystems.
- ToolRegistry.sortedToolNames() sorts tool names before iteration,
ensuring deterministic tool definition order across calls — a
prerequisite for LLM-side prefix/KV cache reuse.
- Merge all context (static + dynamic + summary) into a single
system message for provider compatibility: the Anthropic adapter
extracts messages[0] as the top-level system parameter, and Codex
reads only the first system message as instructions.
- Fix a data race in BuildMessages() where cachedSystemPrompt was
read without holding the lock in a debug log statement.
- Add tests: single system message invariant, mtime auto-invalidation,
new-file creation detection, skill file content change, explicit
InvalidateCache, cache stability, concurrent access (20 goroutines
x 50 iterations, passes go test -race), and a benchmark.
The spawn tool accepts empty strings as valid task arguments, which
causes a subagent to run with no meaningful work. The subagent's
completion message is then routed back to the originating channel
(e.g. Signal, Discord), where the main agent processes it and may
hallucinate an unrelated response that gets sent to users.
Validate that the task parameter is non-empty after trimming whitespace.

Walk backwards over preceding tool messages to find the nearest assistant
with ToolCalls, instead of only checking the immediate predecessor. Add
unit tests for sanitizeHistoryForProvider covering key edge cases.
* chore: Update default host bindings from 0.0.0.0 to 127.0.0.1 for various services and examples.
* config: Update default host bindings to 0.0.0.0 for improved Docker accessibility and add related documentation.
* chore: resolve conflict
* chore: remove link
* docs: Add a tip for Docker users regarding gateway host configuration to the French and Vietnamese READMEs.
* fix: typo issue
* docs: Update Chinese README.zh.md.
- Update Dockerfile to use golang:1.25-alpine to match go.mod (go 1.25.7)
- Optimize logger by avoiding string concatenation in file writes
- Add explicit empty string assignment for fieldStr when no fields
These changes improve build consistency and reduce memory allocations
in the hot logging path, which is important for the project's goal
of running on resource-constrained devices (<10MB RAM).

The configuration field for specifying the model has been renamed from
"model" to "model_name" for better clarity and consistency with the
model_list configuration.
A GetModelName() accessor method has been added to maintain backward
compatibility. Existing configurations using the old "model" field will
continue to work correctly.
This change affects:
- Configuration structure (AgentDefaults struct)
- All references across the codebase
- Documentation in all language variants
- Example configuration files
