What it does
Engineering Wisdom is an agent skill from hoangnb24/repository-harness. Use only when the user explicitly invokes $engineering-wisdom. Provide repository-grounded engineering advice using contextual heuristics. Advice does not establish repository policy or authorize an architecture rewrite.
Its SKILL.md is about 910 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `agents/openai.yaml`, `references/heuristics.md` and `references/sources.md`).
It sits in Agent Workflows. The repository describes itself as: Turn any repo into an agent-ready workspace for Claude Code, Codex, Cursor, and other coding agents. The licence is MIT.
When your agent uses it
- Explicitly invokes $engineering-wisdom
Example prompts
- “/engineering-wisdom”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Read AGENTS.md, docs/WORKFLOW.md, and only the repository material
- Confirm that the user explicitly invoked this skill. Installation alone is
- Determine whether the request is advice/review or an authorized change.
- Read references/heuristics.md. Select only
- When the request crosses a host boundary, inspect the composition root,
What it can do on your machine
Read from SKILL.md and the folder at commit 485fd40. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Engineering Wisdom loads about 910 tokens when it runs, and up to ~4.1k if it reads all its reference files. Until then it costs about 60 tokens; SKILL.md has 400 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- engineering-wisdom
- description
- Use only when the user explicitly invokes `$engineering-wisdom`. Provide repository-grounded engineering advice using contextual heuristics. Advice does not establish repository policy or authorize an architecture rewrite.
Engineering Wisdom
Give practical advice without treating a school of thought as universal law. Repository intent, code, tests, and observed behavior remain authoritative.
Establish Scope
- Read
AGENTS.md,docs/WORKFLOW.md, and only the repository material relevant to the request. - Confirm that the user explicitly invoked this skill. Installation alone is not activation.
- Determine whether the request is advice/review or an authorized change. Keep reviews read-only. For changes, follow repository authority and validation rules before editing.
- Read references/heuristics.md. Select only heuristics that match observed evidence. Read references/sources.md when attribution or the intellectual basis matters.
- When the request crosses a host boundary, inspect the composition root, external input, adapter semantics, shipped artifact, and cumulative state that are relevant. Do not assume isolated core tests prove those boundaries.
Review From Evidence
For each material finding, keep these fields separate:
- Observation: A concrete repository fact with a path, symbol, test, command result, or behavior.
- Heuristic: One named rule of thumb from the catalog and why it may apply.
- Trade-off: Counter-pressure, cost, or a condition under which following the heuristic would make the system worse.
- Proposed repository-owned enforcement: Either
None, or a separately labeled proposal naming the repository owner, authority still required, possible mechanism, and removal condition. Never describe advice as an existing rule unless repository evidence already establishes it. - Verification: A focused observation or executable check that could confirm or falsify the recommendation. Match proof to the claim: test pure policy in isolation, startup at the composition root, and delivery through the artifact users actually load.
Rank findings by user impact and change risk. Prefer one concrete example over several abstract claims.

Advise Before Enforcing
- Do not rewrite application architecture merely because a heuristic suggests a different shape.
- Do not introduce interfaces, layers, tests, linters, size limits, coverage targets, or dependency rules without repository-owned authority.
- Propose the smallest reversible experiment when evidence is incomplete.
- Preserve a deliberate duplication, coupling, integration test, or framework dependency when its local benefit outweighs the heuristic.
- Say when no catalog heuristic materially improves the observed code.
If the user requests implementation and authority is sufficient, make the smallest coherent change and run the repository's own proof. Keep the review rationale separate from the evidence that the change works.
Response Shape
Start with the outcome in one sentence. Then report only material findings:
Finding: <specific effect>
Observation: <repository evidence>
Heuristic: <contextual rule of thumb and applicability>
Trade-off: <counter-pressure or harm condition>
Proposed repository-owned enforcement: None | <owner, missing authority,
mechanism, removal condition>
Verification: <command, test, measurement, or observation>End with unresolved risks or None. Do not add a policy checklist by default.
