plan-guardian-skill

A mandatory 7-step plan, then verification by independent subagents — as a

DeepSeek Harness plugin. The skill ships inside the bundle: install the plugin

and it is there, with the reference documents it cites.

*A Codex skill that enforces verifiable planning, then validates completion with

independent memoryless subagents.*

Install

DeepSeek Harness Desktop — open Plugins in the sidebar, choose **Add

plugin**, and enter:

https://github.com/bauerelizabeth07139/plan-guardian-skill

Then switch the new dsh-plan-guardian bundle on. The Desktop app boots the

reserved desktop profile, so that is where it has to be enabled.

dsh CLI — install it into the profile you actually boot:

dsh plugin --profile web add bauerelizabeth07139/plan-guardian-skill

No git on the machine? pnpm resolves a git shorthand with git ls-remote,

which fails with 'git' is not recognized when git is missing. Use the tarball

instead — that path is plain HTTPS:

dsh plugin --profile web add https://codeload.github.com/bauerelizabeth07139/plan-guardian-skill/tar.gz/master

The same address works in the Desktop Add plugin dialog. Replace master

with a commit SHA to pin an exact revision (/tar.gz/).

Uninstall with dsh plugin --profile web remove dsh-plan-guardian.

The workflow

| Step | What happens |

|---|---|

| 0 | Establish verification capability — once per conversation |

| 1 | Restate the intent; name the core deliverable and the implicit requirements |

| 2 | Draft exactly 7 concrete steps, implementation and verification kept apart |

| 3 | Give every step at least one binary acceptance criterion |

| 4 | Execute through worker subagents — they never see the criteria |

| 5 | Verify every deliverable through a memoryless verifier subagent |

| 6 | On FAIL, revise the plan, re-execute, re-verify |

| 7 | Report every step as PASS or FAIL, with evidence |

Hard rules the skill will not bend: never skip a step, never self-verify, never

produce fewer than 7 steps, never report a step as passed without verifier

evidence.

What changed for DeepSeek Harness

The 7 steps, the hard rules and the acceptance-criteria discipline are

unchanged. Two things are genuinely different:

1. Step 0 is no longer a model probe. In Codex the skill had to discover

whether the session model could see images, by reading ~/.codex and

~/.mimo2codex and probing a model API. On DSH, every agent has read_image,

so visual verification is always available and there is nothing to detect.

The original probe is still in [scripts/detect_multimodal.py](scripts/detect_multimodal.py)

for Codex users; the DSH skill does not call it.

2. Subagent calls are the harness's. subagent (memoryless) replaces

multi_agent_v1__spawn_agent(..., fork_context=false), and a forked

subagent is explicitly forbidden for verifiers because it would inherit the

conversation's assumptions. Workers report back on their own instead of a

separate wait_agent call.
