khashayar 1a70e4c9cd devin harvest: space turns >=5s so single-turn sessions aren't dropped
A harvested single-turn Devin session spanned only 1s (reply written 1000ms
after the prompt), which the engine's harvest filter conservatively classifies
as a <3s headless replay (skillopt_sleep Issue #62) and skips — so a real
single-turn session mined 0 tasks. Widen the prompt->reply gap to 5s. With this,
an end-to-end dry-run mines the task: "night 1: 1 sessions -> 1 tasks".

SkillOpt-Sleep — Devin integration

Give Devin (Cognition) a nightly sleep cycle via a tiny MCP server that exposes the skillopt_sleep engine as tools. MCP is Devin's supported way to add custom tooling, so this works in Devin's CLI and IDE.

Devin doesn't write transcripts in the format the engine consumes, so this plugin adds a Devin-specific harvester that converts every locally available source into the Claude Code-compatible JSONL the engine reads.

What's here

File Purpose
mcp_server.py stdlib-only MCP (stdio) server exposing sleep_* tools
harvest_devin.py converts Devin ATIF-v1.7 transcripts + agentmemory + .devin/skills into JSONL, with taskKey + outcome envelopes
judge.py reference judge for the deferred/judge branch of the validation gate
mcp-config.example.json drop-in MCP server config
devin-rules.snippet.md paste into .devin/rules/skillopt-sleep.md

What it harvests

Source Where
Devin transcripts (ATIF-v1.7) ~/.local/share/devin/cli/transcripts/*.json
agentmemory ~/.agentmemory/standalone.json
Skill files .devin/skills/*/SKILL.md

Workspaces are auto-detected from ~/.config/Devin/User/workspaceStorage/*/workspace.json. After sleep_adopt, the evolved skill is synced to .devin/skills/skillopt-sleep-learned/SKILL.md.

Install

Requires Python ≥ 3.10. No third-party packages — the server is pure stdlib.

  1. Register the MCP server. Use mcp-config.example.json as a template; set args to the absolute path of this mcp_server.py. The engine is found automatically (this plugin lives inside the SkillOpt repo). Or via the Devin CLI:

    devin mcp add skillopt-sleep \
      --env "SKILLOPT_DEVIN_CLAUDE_HOME=$HOME/.skillopt-sleep-devin" \
      -- python3 /abs/path/to/SkillOpt/plugins/devin/mcp_server.py
    
  2. (Optional) copy devin-rules.snippet.md to .devin/rules/skillopt-sleep.md so Devin proactively offers the tools.

  3. Ask Devin: "run the sleep cycle", "what did the last sleep propose?", "adopt it".

Tools

Tool What it does
sleep_status nights run so far + latest staged proposal
sleep_dry_run preview cycle — no staging, no changes
sleep_run full cycle; stages a proposal for review
sleep_adopt apply the staged proposal; syncs skill to the workspace
sleep_harvest debug: list the recurring tasks mined
sleep_schedule install a nightly cron entry (--hour / --minute)
sleep_unschedule remove the nightly cron entry

Default backend is mock (no API spend); --backend claude|codex uses your own budget. Same engine and sleep_* interface as the other plugins — all call python -m skillopt_sleep.
