harness-continue

harness-continue is a skill for Claude Code from oeftimie/vv-claude-harness. It costs 61 tokens per session (7,977 once invoked), scanned A, original, MIT.

A session guide for projects managed by vv-harness, a project-tracking plugin. It helps an agent understand the current work and choose how to continue.

In plain words
What is it for?
Use it at the start of a session to review project status, run a basic check, choose a work mode, and plan implementation with test-driven development (writing tests before code) and quality checks.
Why use it?
It reduces confusion when work is split across coding sessions, especially after context is shortened or handed over. It also helps catch incomplete tasks and unknown files before new work begins.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

harness-continue scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 519 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Harness Continue

Step 1: Orient Yourself

The vv-harness plugin's SessionStart hook auto-injects orientation at session start: feature summary, next claimable feature, last handoff, Active Context, a git identity warning on mismatch, and any SESSION_INCOMPLETE gaps from the previous session. Use that injected "## Harness orientation" block instead of re-reading the harness files. Resolve any SESSION_INCOMPLETE gaps it surfaces before starting new work.

This skill covers what the hook does not: mode choice, the smoke test, and workflow planning.

Check for untracked files and inherited task quality:

git status -s          # surface unknown untracked files

If you see untracked files you didn't create (e.g., notes.md, scratch files), surface them to the user immediately: "I see [file] untracked — should I delete it, gitignore it, or leave it?" This takes 5 seconds and prevents orphaned file accumulation.

If inheriting tasks from a previous session, verify they have required metadata fields (feature_id at minimum) via TaskList. Tasks without feature_id can't be correlated by hooks or retrospectives. Update them with TaskUpdate now if they're missing it.

Step 2: Verify Git Identity

The SessionStart hook already compared git config user.email against .harness/harness.json and warned on mismatch (non-blocking). If the orientation block shows an identity warning, fix it before proceeding. Also verify the SSH identity, which the hook does not check:

ssh -T [email protected] 2>&1 || true

Do not skip this.

Step 2.5: Smoke Test

Run the project's build/test smoke test:

./.harness/init.sh smoke_test

This is a gate, not a diagnostic. Its purpose is to confirm the environment is in a known-good state BEFORE any changes. If it fails, you know the problem is pre-existing, not something you introduced. Run it within the first 5 actions of every session. No exceptions. The 15-second cost prevents 15-minute debugging sessions later. (OVI-106: init.sh's own default target is full_test, not smoke_test -- pass the argument explicitly, or this step silently runs the full suite instead of the fast gate this section describes.)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

harness-continue is a skill published in the GitHub repository oeftimie/vv-claude-harness (19 stars, last pushed 18d ago), licensed MIT. It adds 61 tokens to every session and 7,977 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
