What it does

Orch Change Feature is an agent skill from affaan-m/ECC. Orchestrate altering an existing, working feature to new desired behavior — update its tests to the new spec, change the implementation to match, review, and gated commit. Use when behavior is not broken but should be different.

Its SKILL.md is about 420 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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

  • Behavior is not broken but should be different

Example prompts

  • “/orch-change-feature”

Workflow steps

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

  1. Run the orch-pipeline engine with the settings above.
  2. Keep the plan light — only standard+ size warrants the full planner pass.
  3. Stop at Gate 1 (plan / changed-test approval) and Gate 2 (pre-commit).
  4. Add security-reviewer if the change touches a security trigger.

What it can do on your machine

Read from SKILL.md and the folder at commit 2d515e4. 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 Change Feature loads about 420 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 167 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~420

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-change-feature

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

When to Use

  • An existing feature works, but the desired behavior is different ("change", "adjust", "make it also …", "instead of X do Y").
  • Distinguish from siblings:
    • not broken → not orch-fix-defect (no bug to reproduce).
    • not new → not orch-add-feature (the capability already exists).

Operation settings

  • Default size floor: small — most tweaks are a function or two.
  • Phase mask: 0 → (1 only if the new behavior needs research) → light 2 → 4 → 5 → 6.
  • First move (phase 4): update the existing tests to express the new desired behavior, then change the implementation until they pass. Changing the tests first is what separates a tweak from a fix.

How It Works

  1. Run the orch-pipeline engine with the settings above.
  2. Keep the plan light — only standard+ size warrants the full planner pass.
  3. Stop at Gate 1 (plan / changed-test approval) and Gate 2 (pre-commit).
  4. Add security-reviewer if the change touches a security trigger.

Example

orch-change-feature: make nws-poller alert at 2 warnings instead of 3
→ update threshold tests to new spec → change impl to green
→ code-review → commit  [GATE 2: confirm]
