What's New - TachiBot MCP

v2.26.0July 3, 2026Major Expansion

64 Tools — refine_prompt, Setup Wizard & One-Click Desktop Install

Prompt stack, modernized — refine_prompt (new tool, cheap/fast model): raw query → goal-first brief + what-changed + open questions, never auto-fires or executes. list_prompt_techniques now defaults to the ~9 core techniques (all=true for the full 31); preview_prompt_technique gained technique="auto" recommendations and its tool param is now optional. In Claude Code, /prompt refine presents open questions as clickable choices
Setup, de-mystified — tachibot init (new CLI wizard): detects your API keys and clients, prints the exact config for Claude Code and Claude Desktop, never writes or echoes keys. One-click Claude Desktop install via the .mcpb release asset — no JSON editing
3 new skills — /setup (guided config via doctor), /spec (request → spec), /triage (ranked bug triage). 17 skills total
Fixes — focus orchestration output cut from 37 lines of scaffolding to 10 focused lines; GPT-5.5 high-effort reasoning no longer cut off at 3 minutes (timeout 180s → 600s); npm test exits 0 again
Profile counts updated — minimal 13, code_focus 42, research_power 35, balanced 53, heavy_coding 57, full 64 (default profile)

v2.25.0July 2, 2026New Tools

63 Tools — debug_triage & spec_writer

debug_triage (Grok 4.3) — ranked root-cause hypotheses with likelihoods, the cheapest discriminating check for each, and the minimal fix for the top candidate. Narrows a hypothesis space instead of jumping to one answer
spec_writer (GPT-5.5) — turns a loose feature request into a reviewable spec: user stories, Given/When/Then acceptance criteria, out-of-scope, open questions. For sign-off before planning — feed the approved spec to planner_maker
tachibot init CLI lands (setup wizard: key/client detection, per-client config emission) — expanded further in v2.26.0

v2.24.0July 1, 2026Major Expansion

61 Tools — Security Review, Test Gen, Diff & Plan Red-Team

Four new gap tools — testgen (runnable tests via Qwen3-Coder-Next, edge cases enumerated first), security_review (OWASP/CWE audit via DeepSeek V4 Pro — taint/data-flow analysis, severity + fix per finding), diff_review (multi-model diff-aware review — Kimi K2.7-Code + DeepSeek V4 Pro + GPT-5.5, deduplicated and severity-ranked by a Gemini judge), plan_critique (adversarial plan red-team — pre-mortem, hidden assumptions, ranked risks, Gemini-judged verdict)
doctor now documented — zero-cost setup diagnostic added in an earlier release, only now reflected here: detected API keys, visible vs hidden tools (and why), active profile + source, a concrete first command to try
2 new skills — /review (wraps diff_review on your current git diff), /redteam (wraps plan_critique on any plan). 14 skills total
Profile counts updated — minimal 13, code_focus 39, research_power 35, balanced 50, heavy_coding 54, full 61 (default profile)

v2.23.3June 17, 2026Model Bump

GLM-5.2 — Long-Horizon Coding, 1M Context

GLM-5.1 → GLM-5.2 — z-ai/glm-5.2 (released June 13). Zhipu's open-weights flagship for long-horizon tasks — usable 1M-token context (up from agentic-tier 5.1), two thinking-effort levels (High/Max)
Benchmarks up — SWE-Bench Pro 62.1 (from 58.4), Terminal-Bench 2.1 81.0 (from 62.0); beats GPT-5.5 on several long-horizon coding benchmarks at ~1/6 the cost. List price $1.40/$4.40 per M
Powers glm_reason and the glm juror. GLM-5.1 kept as quota fallback (GLM-5.2 → GLM-5.1 → GLM-5)

v2.23.2June 15, 2026Model Bump

Kimi K2.7-Code — Coding-Specialized, 262K Context

Kimi K2.6 → K2.7-Code — moonshotai/kimi-k2.7-code (released June 12). Coding-specialized variant built on K2.6 — +21.8% on Kimi Code Bench v2 with lower token use, 262K context, native multimodal, always-thinking mode
Now powers all Kimi tools — kimi_thinking, kimi_code, kimi_decompose, kimi_long_context and the kimi juror. List price $0.75/$3.50 per M
Quota fallback — K2.6 retained (K2.7-Code → K2.6 → K2-Thinking). No general-purpose K2.7 exists yet — the coding-tuned model serves reasoning + long-context too

v2.23.1June 11, 2026Model Bump

MiniMax M3 — 1M Context, Sparse Attention

MiniMax M2.7 → M3 — minimax/minimax-m3 (released May 31). 1M-token context (up from 200K), native multimodal, tuned for long-horizon agentic work
MSA sparse attention — ~1/20 the compute of the previous generation at 1M context, with faster prefill and decode
Same promo pricing — $0.30/$1.20 per M tokens, unchanged from M2.7. Powers minimax_code, minimax_agent, and the minimax juror
Quota fallback — M2.7 retained as automatic fallback if M3 hits provider limits

v2.23.0June 11, 2026Refactor

Central Tool Registry + One Honest Local Juror

Central scan registry — all provider tools now register through registry.ts + a defineModelTool factory, with golden wire-contract tests locking all 57 tool schemas. Zero behavior change
Removed the hermes juror — it was a persona prompt on the same local weights as local. Jury independence comes from different model weights, not different system prompts. hermes stays as a deduped legacy alias; 12 jurors total

v2.22.0June 10, 2026Major Expansion

57 Tools — DeepSeek, GLM, StepFun, ERNIE + Free Local Models

Four new reasoning providers — deepseek_reason + deepseek_algo (DeepSeek V4 Pro, top AIME/CodeElo), glm_reason (GLM-5.1, SWE-Bench Pro leader), stepfun_reason (Step 3.7 Flash), ernie_reason (ERNIE 4.5 VL)
Free local models — local_query talks to Ollama, LM Studio, llama.cpp, or vLLM. Zero-cost, offline, private; Ollama uses the native API so long contexts work
12-juror panel — jury adds deepseek, glm, stepfun, ernie, and a free offline local juror (runs whatever LOCAL_LLM_MODEL points at, e.g. a Nous Hermes build via Ollama). New lab-diverse default: grok,deepseek,kimi,openai
3 new skills — /lens (256K long-context analysis), /reflect (grounded reflexion), /tot (Tree-of-Thought with jury pruning). 12 skills total
Grok 4.3 default (v2.21.4) — 1M context, configurable reasoning effort, cheaper than 4.20. Kimi K2.6 hotfix (v2.21.5) — all call sites off the retired K2.5

v2.21.3May 29, 2026Model Bumps

Gemini 3.5 Flash — New Flash + Search Tier

Gemini 3.5 Flash is GA — gemini-3.5-flash shipped at Google I/O (May 19). Agentic/coding focus, 1M context, $1.50/$9 per M. SWE-bench Verified 78.8%
Now the Flash + search tier — gemini_search grounding and the flash variant now route to 3.5 Flash
Reasoning default unchanged — stays on gemini-3.1-pro-preview. Gemini 3.5 Pro is not out yet (expected June 2026)

v2.21.1April 26, 2026Model Bumps

GPT-5.5 + Kimi K2.6 — Frontier Refresh

OpenAI gpt-5.4 → gpt-5.5 — agentic-focused, 1.1M context, omnimodal. Released April 23. gpt-5.5-pro for premium tier ($30/$180)
Kimi K2.5 → K2.6 — 1T MoE, leads SWE-bench Pro for long-horizon coding. Released April 20. Auto-fallback to K2.5 on quota errors
Qwen3.6-Plus available — qwen/qwen3.6-plus registered ($0.325/$1.95). Coder stays on qwen3-coder-next until 3.6-coder ships
API-verified — all model IDs confirmed live via OpenAI /v1/models, OpenRouter, and xAI before release
Holding — Grok 5 unreleased (Q2 expected); Gemini 3.5 in preview (May GA at I/O); gpt-5.4-mini retained for code/explain (no 5.5-mini yet)

v2.21.0April 13, 2026UX Fix

Auto-Alias Param Names — LLMs Stop Failing on Wrong Keys

Transparent remap — query ↔ problem ↔ prompt ↔ question ↔ topic auto-mapped before Zod validation
Zero per-tool changes — one z.preprocess() hook in safeAddTool. Every tool benefits automatically
Eliminates -32602 errors — LLMs that reach for the wrong synonym now succeed instead of hard-failing on schema validation
11 unit tests covering directional aliasing, primary-wins, and missing-key behavior

v2.20.0April 10, 2026Model Bump

Grok 4.20 Flagship — Lower Hallucination, 16-Agent Swarm

Grok 4 → 4.20 — all defaults moved to flagship: grok-4.20-0309-reasoning for reason/search (low hallucination, 2M ctx)
Multi-agent architect — grok_architect now runs grok-4.20-multi-agent-0309 (4–16 parallel agents)
Code/debug/brainstorm — non-reasoning variant for fast turn-around on lighter tasks
Timeout fixes — AbortController on OpenAI (90s default, 180s high-reasoning) + Grok (60–180s by mode). Stops hung calls dead
Cleanup — killed stale grok-4-0709 + gpt-4-mini refs across 6 scattered files

v2.19.1March 21, 2026

MiniMax M2.7 — Self-Evolving AI

MiniMax M2.5 → M2.7 — 2,300B MoE (100B active), 200K context. #1 on Artificial Analysis Intelligence Index
SWE-Pro 56.22% — matches GPT-5.3-Codex. Multi-SWE-Bench 52.7% (#1, beats Opus 4.6 and GPT-5.4)
Same pricing — $0.30/$1.20 per M tokens. Massive quality leap at zero extra cost

v2.18.0March 21, 2026Major Release

AI That Proves Its Work

Stop babysitting LLMs. Deploy a pipeline that reads actual files, cross-examines across five models, and demands passing tests before moving forward.

Absolute goal alignment — define success criteria once. The engine verifies every step against your exact goals — drift gets caught at step 1, not step 50
No blind spots reach production — 5-model rotation cross-examines code: Gemini deduces, Grok detects drift, GPT validates strategy, Qwen cross-checks, Kimi decomposes
Hard evidence, not hallucinated progress — checkpoints demand raw git diffs, passing test results, and modified file lists. Zero reliance on paraphrased summaries
Never hit a dead end — structured amendment protocol detects drift, proposes revisions with evidence and impact analysis. You approve before it pivots
39 tools operate in reality — every analysis tool reads actual source code from disk via the files parameter. Models judge implementations, not stories about them
Your project gets smarter every run — post-completion reflexion saves architectural lessons to your devlog. Knowledge compounds across sessions

v2.17.2March 21, 2026

Files Parameter Rollout + Smart File Reader

files on 8 more tools — grok_architect, grok_brainstorm, openai_explain, openai_search, kimi_code, kimi_long_context, gemini_judge, gemini_brainstorm

All 51 tools audited — zero remaining required enum violations

v2.15.5February 26, 2026

Tool Parameter Fixes + Gemini Stability

Fixed parameter validation on qwen_coder, kimi_code, minimax_code — AI clients were misusing required enum task param. Added query as required primary param, made task optional with defaults
kimi_long_context — task enum now optional (default: analyze)
Gemini 3.1 → 3.0 rollback — Reverted to stable gemini-3-pro-preview (3.1 had timeout/503 issues)
Gemini timeout 30s → 90s — Pro models need longer than Flash
