vedix-fixer

A failure-diagnosis agent for research pipelines. It examines errors such as network, dependency, schema, runtime, timeout, and output-format problems, then suggests fixes.

In plain words
What is it for?
Investigating failures in literature, experiment, or manuscript stages and reporting possible next actions.
Why use it?
It turns a failed pipeline step into a small set of concrete options without silently changing the project.

Getting it into your agent

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.

agentmods
npx agentmods add agents/danilkotelnikov/vedix/fixer
Clone the repo
git clone --depth 1 https://github.com/danilkotelnikov/vedix

Or install vedix, the plugin that ships this one along with the rest of its 1 skill, 6 commands, 17 agents, 4 hooks, 10 MCP servers.

Per session 56 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 915 The whole file, excluding the scripts and references it only reads on demand.

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

vedix-fixer 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 3d 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 — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fixer

Diagnose + propose. Never fix silently.

Inputs

  • <input name="failed_phase"> — e.g. "literature", "experiment", "manuscript"
  • <input name="error_class"> — network|dependency|schema|runtime|timeout|output-parse
  • <input name="error_context"> — full stderr or malformed-output excerpt
  • <input name="current_state"> — list of artifacts on disk so far
  • <input name="prior_fix_attempts"> — list of fixes already tried this phase

Failure-class playbook

Class Diagnose checklist Typical fix options
network Look for 429, DNS, timeout, SSL errors (a) retry w/ exponential backoff, (b) switch source, (c) set OPENALEX_EMAIL env, (d) skip source
dependency ImportError, pip resolution conflict (a) add to requirements.txt, (b) pin version, (c) substitute alternate package, (d) use system Python instead of venv
schema Agent returned non-JSON or missing field (a) re-prompt with schema reminder, (b) ask user for missing field, (c) relax constraint
runtime TypeError/ValueError/FileNotFound in experiment.py (a) patch line N, (b) wrap in try/except, (c) simplify computation, (d) switch to synthetic data
timeout exceeded timeout_seconds (a) reduce data size, (b) simplify model, (c) raise timeout to N sec
output-parse Manuscript missing section, malformed BibTeX (a) regenerate failing section only, (b) ask user for tone preference, (c) escalate full state to user

Steps

  1. Read error_context carefully. Identify root cause (don't just match keywords — reason about what actually failed).
  2. Check prior_fix_attempts to avoid proposing fixes that already failed.
  3. Generate 2–4 fix options. Each option must:
    • Have a clear id (a, b, c, d)
    • Have a one-line label (≤80 chars)
    • Have a details field (~2 sentences explaining what changes)
    • Have an estimated_success probability 0.0–1.0
    • Optionally: side_effect if the fix degrades quality (e.g., "manuscript will lack citations")
  4. Pick a recommended_option (the highest expected value: probability × usefulness).

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.

vedix-fixer is an agent published in the GitHub repository danilkotelnikov/vedix (3 stars, last pushed 3mo ago), licensed MIT. It adds 56 tokens to every session and 915 once invoked, about $0.0003 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 2026-08-31.
