What is nginx-markdown-harness-maintenance?

A maintenance guide and command set for the nginx-markdown-for-agents project’s instructions, documentation, build files, and CI checks. A harness is the project’s tooling and rules for testing agent behavior.

Use it to resolve task intent, route changed files to risk checks, run quick harness checks, and perform fuller checks when documentation or release wiring changes.

It helps identify which specifications and verification checks apply when harness files change. It reduces guesswork about the tests needed before merging.

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	$0.00064	$0.01179
Opus 5.5	$0.00026	$0.00472
Sonnet 5.5	$0.00013	$0.00236
Haiku 4.5	$0.00006	$0.00118

Security

Grade A, and why

nginx-markdown-harness-maintenance 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 1mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/harness_route.py, scripts/test_harness_route.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

NGINX Markdown Harness Maintenance

Keep harness changes aligned with repo-owned truth surfaces and run the right verification matrix with minimal guesswork.

Quick Start

Resolve current spec intent: python3 tools/harness/resolve_spec.py --hint "<task summary>"
Route changed files to risk packs: python3 skills/nginx-markdown-harness-maintenance/scripts/harness_route.py --from-git
Run cheap blockers first: make harness-check
Run focused or umbrella checks from the route output.
If docs/release wiring changed, run: make harness-check-full

Example Output

$ python3 skills/nginx-markdown-harness-maintenance/scripts/harness_route.py --from-git
files: 2
  - docs/harness/README.md
  - docs/harness/HARNESS_MAINTENANCE.md
matched risk packs: 1
  - docs-tooling-drift (docs/harness/risk-packs/docs-tooling-drift.md)
    path hits:
      - docs/harness/HARNESS_MAINTENANCE.md
      - docs/harness/README.md
    keyword hits:
      - docs
verification families: 3
  - [cheap-blocker] docs-tooling
  - [cheap-blocker] harness-sync
  - [umbrella] release-quality

Workflow

Treat AGENTS.md and docs/harness/ as canonical contract surfaces.
Use tools/harness/resolve_spec.py before broad edits. Triage WARN_NEEDS_AUTHOR_REVIEW against the user request and current evidence. Record a resolved warning and continue. Ask only when missing information materially affects correctness or authorized scope; pause only dependent work. Missing optional specs do not block an explicit task.
Use python3 skills/nginx-markdown-harness-maintenance/scripts/harness_route.py --from-git to map changed files/hints to risk packs and verification families from docs/harness/routing-manifest.json.
Build a phased matrix:
- cheap-blocker first
- then focused-semantic
- then umbrella only when needed
On first drift trigger:
- identify minimal changed files related to the failing family
- rerun only affected verification family commands
- run make harness-check before broad retries
- if the same approach yields no new evidence or progress, change approach or escalate with relevant redacted error output and affected surfaces
Keep optional local adapters optional. Missing local files must degrade as SKIP_NOT_PRESENT, not repository failure.
If harness behavior changes, synchronize the affected truth surfaces and consumers in the same change set. Inspect AGENTS.md, docs/harness/, tools/harness/, Makefile, and CI; edit only consumers that need changes.
Follow explicit user scope over skill workflow defaults. Reviews and plans do not authorize writes. If this skill causes a pause, link this file, quote the applicable instruction, and explain the unresolved dependency.
Finish after applicable checks pass. Repeat checks only for new edits, failures, or unresolved risks; retain required production-code gates.

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
