What it does

Orch Fix Defect is an agent skill from affaan-m/ECC. Orchestrate fixing a bug — reproduce it as a failing regression test, fix to green, review, and gated commit — by delegating each phase to the matching ECC agent. Use when existing behavior is broken or wrong.

Its SKILL.md is about 410 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA. The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.

When your agent uses it

  • Existing behavior is broken

Example prompts

  • “/orch-fix-defect”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Run the orch-pipeline engine with the settings above.
  2. If the root cause is unclear, scope it with code-explorer before the red
  3. Stop at Gate 1 (only if a plan was produced) and Gate 2 (pre-commit).
  4. Add security-reviewer if the defect sits in a security-sensitive path.

What it can do on your machine

Read from SKILL.md and the folder at commit 4eb71d9. 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

Orch Fix Defect loads about 414 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 170 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~414

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.

orch-fix-defect

Actor · action · target: orch · fix · defect. Thin wrapper over the shared engine in orch-pipeline.

When to Use

  • Something is broken: wrong output, an error, a crash, a regression.
  • Distinguish from siblings:
    • behavior is correct but you want it different → orch-change-feature.
    • the capability does not exist yet → orch-add-feature.

Operation settings

  • Default size floor: small (often trivial).
  • Phase mask: 0 → (light 2 only if root cause is non-obvious or standard+) → 4 → 5 → 6. Research (1) is usually skipped.
  • First move (phase 4): reproduce the bug as a new failing test (regression test), then fix until it goes green. Proving the bug exists first is what separates a fix from a tweak.

How It Works

  1. Run the orch-pipeline engine with the settings above.
  2. If the root cause is unclear, scope it with code-explorer before the red test; escalate build breaks to build-error-resolver / /build-fix.
  3. Stop at Gate 1 (only if a plan was produced) and Gate 2 (pre-commit).
  4. Add security-reviewer if the defect sits in a security-sensitive path.

Example

orch-fix-defect: poller crashes on empty NWS response
→ write failing test reproducing the crash → fix to green
→ code-review → commit  [GATE 2: confirm]   (commit: fix:)
