V4 Flash "god mode" for DeepSeek Harness: w7 persona anchoring + first-turn tool anchoring + complexity-dispatched guidance — turn Flash's unstable thinking into reproducible capability.

简体中文版见 README.zh.md

V4 Flash on reasoning: max is powerful but unstable: it over-thinks simple tasks, under-thinks complex ones, and drifts mid-session. This plugin turns that instability into a routed capability, using the measured persona bands from dsh-router-standard:

• w7 persona (author-measured Flash optimum) — neutral identity + classify-then-act instruction + recall/anti-runaway anchors. No deep-thinking sentence baked in (author's correction: per-message guidance is negative on related-task chains, P21).
• Complexity-dispatched guidance — complex tasks get the decision-closure deep guide, simple tasks get the fast-convergence guide. Dispatched on the very first request, thanks to a capture path that works on headless (see below).
• First-turn tool anchoring — the first request sees only the core tool set (read/write/edit + shell); after the first durable tool call the full catalog is exposed.

Dependencies: DSH 0.1.x (headless profile) + any openai-completions provider (built and tested with the opencode-go channel, deepseek-v4-flash, reasoning: max).

Why the capture path matters

The author's own router reads the first user message via user/message events. On headless, that event lands after the first prompt assembly — too late for the path-committing first request. This plugin listens for agent/inbox/spliced instead, which carries the task text before the first assembly (verified on rc.6 headless). Result: the guidance decision is present on request #1, where it counts.

Quick start

# bundle install (recommended)
dsh plugin --profile headless add github:Cavan-Ou/dsh-flash-godmode

# verify: run any task; stderr shows the dispatch decision
dsh --profile headless "简单任务：运行 python3 -c 'print(1+1)' 并报告输出" 2>&1 | grep godmode
# → [godmode] taskLen=NN complex=false guide=fast mode=weak

Flash models are routed to weak mode automatically (model-id detection). Non-Flash models fall back to keyword task classification (react/spec/weak).

Observed results

Result	Evidence
Complexity dispatch works end-to-end on headless	2026-08-18, three real runs: simple task → guide=fast (1-step convergence); refactor/architecture task → guide=deep (decision-closure guide, deep analysis proceeded); multi-turn write+run task → completed correctly with tool anchoring intact. 3/3 passed
Environment-check rumination suppressed	2026-08-15 five-anchor experiment: echo/whoami/uname/node --version/date calls recognized as wasted turns and suppressed via the anti-runaway anchor (now also a global rule in the workspace's ~/.dsh/AGENTS.md)
Zero tool failures across real sessions	Observation journal, 2026-08-15/16: 8 sessions, 129 tool calls, 0 failures
w7 persona is the measured Flash optimum (author-published)	dsh-router-standard: discrimination +5.67 (P11), single-task completion 100% (P23), decision-closure deep guide: depth +12% with faster convergence 8.0 vs 8.3 steps (P30)

Known edges

• The complexity heuristic (text.length > 120 or architecture keywords) is the author's original — a filename like analyze.py counts as complex. False positives lean toward the safe direction (deep guide, not no guide).
• If the agent/inbox/spliced capture fails on a future DSH version, the plugin falls back to the bare w7 persona (no guidance) — safe per P23, and the task still runs.
• All author-measured numbers above come from the official DeepSeek API; this plugin was verified on the opencode-go channel (same weights, different serving) — see the local runs in the table.

Relationship to dsh-routing-suite

dsh-routing-suite is the author's full kit (runtime injector + router presets) aimed at the web profile (PowerShell installer, preset selection per session). This plugin is the headless-native single-plugin form: installable via dsh plugin add, no installer script, first-request guidance on headless (which the suite's own issue tracker flags as not taking effect on rc.6).
