fix

A plan-aware repair loop that runs tests, linting, formatting, and code-connection checks after implementation. It can update the status of tasks in the development plan and makes up to three repair attempts.

In plain words
What is it for?
Use it after implementing planned work to find and fix failing tests, lint issues, formatting problems, and graph-related risks in changed files.
Why use it?
It gathers common post-coding checks in one process and ties problems back to the implementation plan. This reduces manual back-and-forth when code does not pass validation.

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.

Security

Grade A, and why

fix 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/supergraph:fix

Plan-aware auto-fix loop. Ensure tests pass, lint clean, format applied, graph risks handled.

Usage

/supergraph:fix | /supergraph:fix plan auth-login | /supergraph:fix plan auth-login task 2

Steps

0. Announce

"🔧 /supergraph:fix — starting auto-fix loop..."

1. Select Plan Context

0 plans → skip | 1 → use | >1 → ask | plan <slug> → match. Read ## Environment Context, fix scoped task or all in-progress/stuck tasks.

2. Get Commands

Read from plan ## Environment Context or .supergraph-env (set by /supergraph:scan). Missing → STOP, run scan first. Missing command → skip phase, report as SKIP.

3. Get Changed Files

git diff --name-only && git diff --cached --name-only. Reindex CBM_PROJECT if stale (index_statusindex_repository, see references/codebase-memory-contract.md) via codebase-memory-mcp.

3b. Serena pre-loop (optional): See serena/SKILL.md:Setup. If scan not run, call initial_instructions; get_diagnostics_for_file per changed file to catch type errors early. Skip if SERENA_ACTIVE=false or unavailable.

4. Auto-Fix Loop (max 3 iterations)

At iteration start: "🔧 Fix iteration N/3 — running tests..."

Phase Action
Reproduce Smallest failing cmd + expected vs actual
Tests Targeted tests else $TEST_CMD; fix source. Dedup: if same HEAD_SHA and last PASS <120s and git diff unchanged, reuse evidence; else rerun fresh (respects verify freshness guard)
Serena fix get_diagnostics_for_file + replace_symbol_body/rename_symbol (see serena/SKILL.md)
Format+Lint $FORMAT_CMD$LINT_CMD; rerun lint if formatted
Graph Reindex CBM_PROJECT if stale (index_statusindex_repository) — respect scan: TTL 10m (skip index_repository if fresh per .supergraph-env), then codebase-memory-mcp recipes cycles/test-gaps/complexity/cross-boundary
Decide All clean→break else continue

5. Update Plan Status (if plan exists)

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.

fix is a skill published in the GitHub repository datit309/supergraph (21 stars, last pushed 4d ago), licensed MIT. It adds 33 tokens to every session and 824 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
