What is sruja-harness?

A verification checklist and command-line tool for checking work produced by other AI coding add-ons before it is marked complete.

Use it after coding, bug fixing, refactoring, or reviewing changes. It runs checks for code quality, tests, unintended drift, and alignment with the task.

It helps catch failed tests, style problems, unintended changes, and mismatches with the requested task. When checks fail, it records what should be corrected before trying again.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add sruja-ai/sruja --skill sruja-harness

Clone the repo

git clone --depth 1 https://github.com/sruja-ai/sruja

Made for: Claude Code, Codex.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.

Model	Per session	Once invoked
Fable 5.1	$0.00058	$0.00628
Opus 5.5	$0.00023	$0.00251
Sonnet 5.5	$0.00012	$0.00126
Haiku 4.5	$0.00006	$0.00063

Measured 2mo ago against content hash f69820df717b, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

sruja-harness 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 2mo 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.

What it actually says

Sruja Harness Skill

Universal verification adapter — works with any coding, bugfix, or review skill.

Quick Start

Install alongside other skills:

npx skills add https://github.com/sruja-ai/sruja --skill sruja-harness
npx skills add https://github.com/sruja-ai/sruja --skill sruja-architecture

Use with any skill: This skill does not generate code. It verifies output from other skills.

Before marking a task done:

sruja verify-task --profile coding -r .

On verify failure:

sruja agent record -r . \
  -c "<task context>" \
  -H "<what was tried>" \
  -o failed \
  -g "<correction for next time>"

Rules

Always verify before done — Run sruja verify-task with the appropriate profile before declaring a task complete.
Profile selection:
- coding — New features, refactors (default)
- bugfix — Bug fixes (use --file to target the bug location)
- review — Pre-merge review of changes
- arch — Architecture/DSL changes
On failure: Record a correction learning before retrying.
On success: Optionally record an affirmation learning ("what worked").

Integration with Other Skills

Coding Skill (e.g. /build) → sruja-harness verify → record_learning → done

This skill does not replace coding skills — it ensures their output passes Sruja's architecture gates.

Profiles

Profile	Verifies

Changes

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.
