The bundled plan skill's auto-generated slash command fell off the capped
Telegram/Discord command menus for most installs (skills are the only tier
trimmed at the platform caps, alphabetically — 'plan' sat past the cutoff at
index 57 of 82 bundled skills). Converting it to a first-class CommandDef
gives it a guaranteed core-tier menu slot on every platform.
- agent/plan_prompt.py: build_plan_prompt() — plan-mode rules + authoring
craft distilled from the retired skill; prompt-injection pattern like
/learn and /init (no engine, no model-tool footprint, cache-safe).
- CLI: _handle_plan_command mixin handler (pending-input injection).
- Gateway: /plan branch rewrites event.text and falls through (role
alternation preserved).
- TUI: command.dispatch branch ('plan' was already in
_PENDING_INPUT_COMMANDS).
- Removed skills/software-development/plan/ + docs pages (EN + zh-Hans),
catalog rows, sidebar entry, related_skills references.
- PROTECTED_BUILTIN_SKILLS is now empty (mechanism kept); dependent
curator/usage tests moved to monkeypatched sentinels.
Salvages #67292 by @webtecnica (credit: first /plan command submission,
issue #67264); reworked from inline planning prompt to the prompt-injection
pattern with workspace-saved plans. Closes#67264, closes#36821 (empty
/plan infers task from conversation context).
Claude Code's /simplify was renamed away, community-restored, and rebuilt
since our 3-agent port (v2.1.63 -> v2.1.154+). This brings simplify-code
in line with the current upstream design, re-expressed in our own wording
and layered onto our existing risk-tier/confidence machinery:
- New Reviewer 4 (Altitude): flags band-aid fixes layered on shared
infrastructure — special cases, symptom patches with unfixed sibling
sites, workaround stacks — and points at the deeper mechanism fix.
Matches our AGENTS.md 'fix the class, not the site' rubric.
- Explicit cleanup-vs-bug-hunt boundary: this skill improves working
code; correctness review stays with requesting-code-review.
- Inline single-pass fallback when delegate_task is unavailable (leaf
subagents, delegation disabled) — previously the skill just broke;
now all four angles run sequentially with honest disclosure.
- Finding format gains a concrete-cost field.
- Efficiency reviewer adds closure-capture scope-retention leaks.
- Pitfalls: fan-out cap 3 -> 4, band-aid-vs-deliberate-boundary caveat,
no-bug-hunting drift guard.
Kept our value-adds upstream lacks: SAFE/CAREFUL/RISKY tiers,
Chesterton's Fence via git blame, dry-run/focus/scope modifiers.
Five targeted enhancements to the upstream simplify-code skill:
1. Risk-tiered application (SAFE/CAREFUL/RISKY) — safe changes auto-applied,
careful changes verified per-file, risky changes flagged for human review.
Prevents auto-applying N+1 restructures and public API renames.
2. Chesterton's Fence — before flagging anything for removal, reviewers run
'git blame' to understand why it exists. Low-confidence findings are
escalated rather than guessed.
3. AI slop detection — Quality reviewer now catches: extra comments restating
obvious code, unnecessary defensive null-checks on validated inputs, 'as any'
casts, and patterns inconsistent with the rest of the file.
4. Silent failure detection — Efficiency reviewer now catches: empty catch
blocks, ignored error returns, except:pass, .catch(()=>{}) with no handling,
and error propagation gaps.
5. Structured reviewer output with confidence+risk tags — reviewers report in
'file:line → problem → fix | confidence: H/M/L | risk: SAFE/CAREFUL/RISKY'
format, enabling the orchestrator to tier the application.
Plus 3 new pitfalls: over-trusting dead code tools, public contract awareness,
and preserving intentional error handling.
Total: +45/-8 lines. Keeps the 212-line compact spirit.
Ref: #379
Inspired by Claude Code's /simplify. A bundled skill that captures recent
changes via git diff, fans out three focused reviewers (reuse, quality,
efficiency) via delegate_task batch mode, then aggregates findings and
applies the fixes worth applying.
Zero core changes — orchestrates existing tools (terminal/git, search_files,
delegate_task). Supports focus, dry-run, and scoped-diff modifiers.
Closes#379.
