This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL. - Find the right fix for a failing Harness run: https://dedupedai.com/use-cases/sandbaseai-deepseek-harness-handbook/find-fix-for-failing-harness-run/ - Score a Harness setup against a reference scorecard: https://dedupedai.com/use-cases/sandbaseai-deepseek-harness-handbook/score-harness-setup-with-scorecard/ - Vet an ecosystem plugin before you install it: https://dedupedai.com/use-cases/sandbaseai-deepseek-harness-handbook/vet-awesome-resource-before-install/ - Recover Web startup when one corrupt Session blocks it: https://dedupedai.com/use-cases/sandbaseai-deepseek-harness-handbook/recover-web-startup-from-corrupt-session/ ## How to find the right fix for a failing Harness run with DeepSeek Harness Handbook Repo: [sandbaseai/deepseek-harness-handbook](https://github.com/sandbaseai/deepseek-harness-handbook) | Difficulty: Intermediate | Time: 15 minutes | Basis: From the README Route a failing DeepSeek Harness run to the guide that matches its failure boundary. **Who it is for:** A developer or operator whose DeepSeek Harness session fails and who needs the right runbook before retrying. **The problem:** Generic retries waste time when the failure sits in a different layer, such as auth, Session storage, or the sandbox. **The outcome:** One named failure boundary, one linked troubleshooting guide, and the evidence to collect before changing anything. ### Steps 1. Open the Interactive Failure Router at https://sandbaseai.github.io/deepseek-harness-handbook/diagnose.html. 2. Choose the symptom closest to what you see and note the boundary it points to. 3. Open the matching guide in docs/en/troubleshooting/, for example docs/en/troubleshooting/session-history-corruption-triage.md for a Web startup failure. 4. Check the guide's acceptance gates and collect the evidence it asks for before you change configuration. 5. If the guide does not match your runtime, open an evidence report at https://github.com/sandbaseai/deepseek-harness-handbook/issues/new/choose with the exact DSH version and first failing boundary. ### Prompt to paste into your agent ```text Using the DeepSeek Harness Handbook (sandbaseai/deepseek-harness-handbook), take this symptom: . Use the Interactive Failure Router and the docs/en/troubleshooting/ folder to name the failure boundary and the single guide to follow. Output the guide path, the first evidence to collect, and one check that would show the guide does not match my runtime. ``` ### Caveat The handbook is community-maintained and independent of DeepSeek AI, so a matching guide is a lead to verify, not a guaranteed fix. Risk, credentials: Do not paste API keys, private Session logs, or sensitive workspace data into a public issue or chat while collecting evidence.

Open the Agent Harness Scorecard at https://sandbaseai.github.io/deepseek-harness-handbook/agent-harness-scorecard.html. 2. Read the Agent runtime map at docs/en/architecture/agent-runtime.md to see how model routing, tools, approval, sandboxing, and Sessions connect. 3. Mark each scorecard item as present, missing, or unknown for your own setup. 4. For each missing or unknown item, open the guide the scorecard links to and note the acceptance gate it lists. 5. Record the DSH version and source revision you checked so the results stay version-specific. ### Prompt to paste into your agent ```text Using the sandbaseai/deepseek-harness-handbook repo, read the Agent Harness Scorecard and the Agent runtime map, then score my setup described as: . Output a table of scorecard items marked present, missing, or unknown, with the guide to read for each gap. Verify that you recorded the DSH version I give you. ``` ### Caveat The scorecard is a reading aid built from the handbook's source-backed guides, so it describes the boundaries to check rather than certifying your setup.

Open the Awesome resource map at https://sandbaseai.github.io/deepseek-harness-handbook/awesome-deepseek-harness-resources.html and find the entry you want. 2. Follow the entry's source link and read what permissions and credentials it asks for. 3. Confirm the rollback path the entry documents before you install anything. 4. Check the handbook's Awesome resource guide at docs/en/ecosystem/awesome-resources.md for the agent boundary it names for that resource. 5. Install only in a setup you can reset, and record the source revision you tested. ### Prompt to paste into your agent ```text Using the sandbaseai/deepseek-harness-handbook Awesome resource map, review the entry named . Follow its source link and report the permissions, credentials, and rollback path it requires. Output a go or no-go recommendation and one permission you would refuse to grant. ``` ### Caveat The handbook says each Awesome entry is an Agent-oriented discovery lead, not a compatibility or security endorsement, so the final check is yours. Risk, credentials: Never give a community plugin your API keys or workspace credentials until you have read what it requests and how it stores them.

Open docs/en/troubleshooting/session-history-corruption-triage.md and confirm your error matches a plugin tree failed to load message. 2. Identify the one Session artifact the guide says may hold a bad Zstandard header. 3. Isolate that artifact before you change the launcher, the profile, or any other Session. 4. Start the Web client again and check that it loads. 5. If startup still fails, keep the evidence and follow the handbook's failure router at https://sandbaseai.github.io/deepseek-harness-handbook/diagnose.html. ### Prompt to paste into your agent ```text Using the sandbaseai/deepseek-harness-handbook troubleshooting guide session-history-corruption-triage, help me with this startup error: . Identify the single Session artifact to isolate, and output the steps in order without changing the launcher or profile. Verify the Web client starts and that no healthy Session was altered. ``` ### Caveat The guide describes a Windows failure pattern, so confirm your error text matches it before isolating any artifact. Risk, credentials: Session logs can contain sensitive workspace data, so keep them local and do not share them publicly while you debug. Disclaimer: Third-party repos we don't own or vouch for.
