- **[code-quality]** Docstrings and comments must stay in sync with code; renaming functions without updating docs creates lying documentation.
- **[testing]** Test function names get corrupted during bulk find-replace; verify test names remain valid after refactoring.
- **[code-quality]** Catch specific exception types (e.g., OSError, TimeoutExpired) instead of bare `except Exception` to avoid swallowing bugs.
- **[code-quality]** Use line-anchored regex (`^target:`) instead of substring checks (`"target:" in text`) when parsing structured files.
- **[architecture]** Extract duplicated inner functions (e.g., UI factories) into shared helpers rather than copy-pasting closures across methods.

_Date: 2026-03-18 | Feature: add_a_colonyos_stats_cli_command_that_reads_all_persisted_ru_

- **[code-quality]** Remove unused function parameters (e.g., accepted but ignored args) that mislead callers about behavior.
- **[style]** Move imports to module-level; imports inside loop bodies signal hasty implementation and reduce readability.
- **[architecture]** Keep feature branches single-purpose; unrelated changes increase rollback blast radius and pollute diffs.
- **[code-quality]** Delete unreachable code guards (e.g., filters redundant with an upstream glob); dead code misleads maintainers.
- **[code-quality]** Document implicit ordering contracts between components with comments to prevent silent breakage.

- **[security]** Sanitize user-controlled strings before interpolating into structured templates (XML, prompts) to prevent injection attacks.
- **[architecture]** Private (_prefixed) functions imported across module boundaries should be made public or moved to a shared module.
- **[testing]** Verify claimed test coverage actually exists in code; task descriptions listing tests don't guarantee implementation.
- **[code-quality]** Functions returning True for empty collections (e.g., `all_pass([])`) create silent semantic bugs; handle empty inputs explicitly.
- **[code-quality]** Silently swallowing network/IO failures (e.g., fetch, push) gives false confidence; log or propagate the error.

_Date: 2026-03-18 | Feature: add_a_colonyos_show_run_id_cli_command_that_renders_a_detail_

- **[architecture]** Return `str | list[str]` union types are fragile; use typed result dataclasses to make dispatch explicit and safe.
- **[code-quality]** CLI flag combinations that are logically useless (e.g., `--max-retries` without `--wait`) should auto-correct or warn the user.
- **[security]** Validate inputs at public function boundaries even when current callers pre-validate; defense-in-depth prevents future misuse.
- **[code-quality]** Implemented but never-called functions are dead code; wire them in or document them as forward-looking with a comment.
- **[style]** Duplicate near-identical branches (differing by one variable) should be collapsed into a single branch with a parameter.

_Date: 2026-03-18 | Feature: add_a_colonyos_queue_command_that_accepts_multiple_feature_p_

- **[security]** Exception messages persisted verbatim may leak secrets from tracebacks; redact or truncate before writing to disk.
- **[architecture]** Register signal/cleanup handlers before marking mutable state transitions to prevent crash-orphaned resources.
- **[code-quality]** Use enums instead of plain strings for fields with a fixed set of valid values to enable type-checking.
- **[architecture]** Extract feature logic from CLI entry-point files into dedicated modules; god files (>500 LOC) hinder review and testing.
- **[testing]** Test cross-command integration points; a subcommand passing its own tests doesn't guarantee correct parent output.

_Date: 2026-03-18 | Feature: i_think_we_should_add_some_sort_of_ui_for_managing_all_this__

- **[security]** Resolve user-supplied file paths and verify they stay within the allowed base directory to prevent path traversal.
- **[architecture]** Hand-maintained type mirrors across languages (e.g., TS types for Python models) drift silently; generate or validate via shared schema.
- **[code-quality]** Manual serialization helpers that enumerate fields silently drop new fields; co-locate serialization with the data model.
- **[security]** HTTP error handlers forwarding raw exception messages to clients can leak internal filesystem paths and stack details.

- **[code-quality]** Config loaded once before a long-running loop goes stale; reload configuration at the start of each iteration.
- **[code-quality]** Deserialization via direct key access (`d["key"]`) crashes on corrupted data; use `.get()` with defaults for resilience.
- **[security]** CORS allowed-origins must be scoped per environment; leaving dev-server origins in production builds weakens isolation.
- **[architecture]** Mutable state files (queues, logs) lack append-only audit trails; add forensic logging for add/remove operations.
- **[code-quality]** Reusable format/parse helpers (e.g. duration formatting) get copy-pasted instead of importing the shared utility.

_Date: 2026-03-19 | Feature: every_time_the_pipeline_starts_we_should_look_at_what_branch_

- **[architecture]** CLI god files (>2000 LOC) must be split proactively; extract each subcommand's helpers into dedicated modules.
- **[security]** Use allowlist serialization (explicit field inclusion) instead of blocklist (pop sensitive fields) to prevent leaking new fields.
- **[testing]** CLI entry points (flags, import guards, argument parsing) need dedicated unit tests separate from the underlying logic tests.
- **[code-quality]** Polling intervals using setInterval with stale closures cause subtle bugs; use refs or re-subscribe on dependency changes.
- **[architecture]** Prompt templates should use concrete glob patterns instead of natural-language directory descriptions to reduce ambiguity.
