bugfix

A guided workflow for finding the cause of a software bug, applying a fix, checking the result, and adding a regression test.

In plain words
What is it for?
It is for investigating bug reports, confirming the proposed cause, implementing the fix, verifying it, retrying changes when needed, and adding a test that catches the bug again.
Why use it?
It separates investigation, implementation, verification, and testing so a reported bug is not fixed without checking that it stays fixed.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

bugfix 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 2d ago.

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 — 289 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/soloflow:bugfix

You are running the SoloFlow bugfix workflow. The user has reported a bug. Your job is to:

  1. Identify the bug — spawn the bug-investigator to do read-only root-cause analysis.
  2. Confirm the hypothesis with the user (unless --no-confirm is in $ARGUMENTS).
  3. Resolve the bug — spawn the executor with a precise plan derived from the investigation.
  4. Verify the fix — spawn shadow-verifier; on NEEDS_CHANGES, retry the executor.
  5. Lock it in — spawn test-writer to add a regression test.

This command is a sibling of /soloflow:quick. Both run a single task inline (no run branch, no worktree, no parallelism, no per-task code review). The difference: /quick assumes the user already knows the fix; /bugfix performs a dedicated investigation step first and gates on user confirmation before any code changes.

The bug report is: $ARGUMENTS

Parse $ARGUMENTS for the optional --no-confirm flag. If present, strip it from the bug report text before passing the rest to the investigator, and skip the confirmation gate in Step 4.

Step 1: Resolve models + limits (cache for the rest of the run)

Run once at the start, cache the result:

node "${CLAUDE_PLUGIN_ROOT}/scripts/config/resolve.js" --all

Keys consumed:

  • models.bug_investigator (fallback: opus) — the investigator runs Opus by default for judgment.
  • models.executor / models.test_writer (fallback: sonnet)
  • models.verifier (fallback: opus)
  • limits.executor_retry_max (fallback: 3) — cap on NEEDS_CHANGES retries in Step 8.
  • limits.context_limit_respawn_max (fallback: 3) — cap on CONTEXT_LIMIT respawns for any agent.

Reuse the cached values across all agent spawns and respawns. Also cap investigator re-spawns (after INVESTIGATION_INCONCLUSIVE + new user input in Step 3) at 2 — independent of the context-limit budget.

Step 2: Check initialization

If .soloflow/ does not exist, report: "SoloFlow not initialized. Run /soloflow:init first." and stop.

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.

bugfix is a command published in the GitHub repository kesteva/soloflow (41 stars, last pushed 3mo ago), licensed MIT. It adds 23 tokens to every session and 3,750 once invoked, about $0.0001 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.
