Sync this port with upstream obra/superpowers or Reasonix main-v2: detect drift, re-port, bench-gate

  • Works in 6 steps: Detect → Classify content drift → Re-port → …

  • SKILL.md covers 1. Detect, 2. Classify content drift, 3. Re-port and 4. Classify harness drift, plus 2 more sections
  • Calls git and node

What it does

Superpowers Sync Upstream is an agent skill from christopherarter/superpowers-reasonix. Sync this port with upstream obra/superpowers or Reasonix main-v2: detect drift, re-port, bench-gate

Its SKILL.md is about 750 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 Development. It works with Git. The repository describes itself as: Superpowers skill port to Reasonix coding harness. The licence is MIT.

When your agent uses it

  • Development work in your project

Example prompts

  • “/superpowers-sync-upstream”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Detect
  2. Classify content drift
  3. Re-port
  4. Classify harness drift
  5. Bench-gate
  6. Finalize

What it can do on your machine

Read from SKILL.md and the folder at commit d202ba4. 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

    Shell commands in SKILL.md call:

    • git
    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    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

Superpowers Sync Upstream loads about 752 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 352 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~752

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.

Sync Upstream

Re-aligns this port with its two upstreams and re-pins UPSTREAM.json. Run when asked to sync or update from upstream, or after the upstream-drift CI issue fires.

1. Detect

Read UPSTREAM.json for the pinned commits and watched paths, then see what moved:

node .github/scripts/check-upstream-drift.mjs prints which upstreams drifted (read-only).

For full diffs, shallow-fetch and compare from the pins:

git clone --filter=blob:none --no-checkout <obra.repo> /tmp/obra && git -C /tmp/obra diff <obra.lastSyncedCommit>..HEAD -- skills/

git clone --filter=blob:none --no-checkout <reasonix.repo> /tmp/rx && git -C /tmp/rx diff <reasonix.lastVerifiedCommit>..origin/main-v2 -- internal/tool internal/hook internal/skill internal/frontmatter internal/command

Network blocked? web_fetch the GitHub compare page: <repo>/compare/<pinned>...<branch>. This step is read-only; dispatch it to a task subagent and keep only the drift report to save context.

2. Classify content drift

For each changed obra skill, decide edited, new, or removed.

  • New skill: port it only if no native Reasonix tool already covers it (task, review, wait, explore). Otherwise add it to UPSTREAM.json retired with a one-line reason.
  • Removed upstream skill: consider retiring the port equivalent.

3. Re-port

Load superpowers-writing-skills. For each edited or to-be-ported skill, apply the Adaptations rules: snake_case tool names (read_file, edit_file, bash), description rewritten as a forceful imperative within the 130-char index budget, references/* auto-fold, native-tool substitution, path renames (docs/reasonix/...). Preserve the disciplines verbatim: Iron Laws, red-flag tables, RED-GREEN-REFACTOR. Keep bodies lean enough for the flash model.

Show full SKILL.md (134 more words)Show less

4. Classify harness drift

Map each changed contract file to the port surface it touches:

  • internal/tool: tool names in every skill body and bench/reasonix.toml
  • internal/hook: AGENTS.md notes and any hook docs
  • internal/frontmatter: all skill frontmatter
  • internal/skill, internal/command: layout, loading, and /name assumptions

Update the affected skills, AGENTS.md, and bench config. If the change invalidated the local reasonix binary, rebuild it before trusting bench.

5. Bench-gate

  • node --test bench/structural.test.mjs (structure of every SKILL.md)
  • node bench/bench.mjs (invocation; prior cases must still pass)
  • exec-fidelity for any re-ported discipline skill, vs bench/BASELINE.json

Any structural failure or exec score below baseline blocks acceptance. Fix the skill body; do not lower the baseline.

6. Finalize

Bump UPSTREAM.json commits and dates to the synced HEADs, close the open upstream-drift issue, write a short report (changed, ported, retired, bench result), and commit.
