What is the Belief Rot Index?
The Belief Rot Index is a weekly publication that scans public repositories for agent instruction files to identify 'zombie beliefs,' which are retracted rules that have reappeared. It produces a census listing tracked repositories along with a score, the number of zombie rules detected, and how long the oldest one has persisted. Repositories remain unnamed unless their owners have explicitly consented to be named.
How can I check my own repository for zombie beliefs?
Users can verify a receipt or check their own repositories by running the accompanying sagrada-linter tool locally on their machine. Repository owners can add their projects to the index through a self-listing process. The project is run by Cruxia and presents its findings as a weekly census of zombie beliefs.
How frequently is the census updated and what were the latest results?
The index operates on a weekly cycle, with the latest census covering the period from 2026-W44 to 2026-W45. During this review, 0 zombies were found, 0 were interred, and 0 were rotten, representing a 31.6% change from the previous week. One high-count row is currently quarantined as a probable detector artifact pending review.
What technology is used to scan repositories?
The sagrada-linter tool runs entirely on a user's machine and can be invoked with the command 'uvx sagrada-linter read .copy'. This allows for clean reading and verification without needing external services. The tool is available on PyPI and GitHub.
What types of files and frameworks are included in the index?
The index tracks various types of files including AGENTS.md, CLAUDE.md, and rule files. It covers tracked developer tools, agent-tooling libraries, and agent frameworks. The Cruxia-Labs/cruxia-engines and Cruxia-Labs/sagrada-linters are self-listed with a score of 1000.
How are repositories named in the index?
No outside repository has consented to be named yet, meaning all non-self-listed entries remain unnamed. The two named rows are the self-listed entries for the Cruxia-Labs projects. Corrections ship in public with receipts, and every named claim recomputes on the user's machine.
Who runs the project and what industries does it serve?
The project is run by Cruxia and is categorized under Computer software, Publishing, and Information services. It provides a census of zombie beliefs by scanning public repositories for retracted rules that are back in force. The website states that agents read these files as standing instructions.
What is the official website of the Belief Rot Index?
The official website of the Belief Rot Index is beliefrotindex.com.
How is the Belief Rot Index rated on Trustburn?
On Trustburn, the Belief Rot Index has a rating of 4.3 out of 5 based on 4 reviews.
The Belief Rot Index is an interesting tool for tracking zombie beliefs. It compares well against other monitoring services by focusing on retracted rules. However, the method section could be clearer about how scores are calculated. I noticed that some rows are flagged as probable detector artifacts. It would be helpful to know if these are excluded from the final score. The availability of public repos is a strong point, but I wish there was more historical data. Overall, it is a useful addition to the developer toolkit, though it still has some growing pains.
The range of scores from zero to one hundred provides a comprehensive view of repository health. I appreciate how the index distinguishes between zombie counts and days walking. It is reassuring to see that unnamed rows are itemized from the last reviewed bank. This level of detail helps in understanding the actual state of agent frameworks. The self-listed rows add a nice touch of community involvement.
I am absolutely thrilled with how The Belief Rot Index operates! The fact that they re-read agent instruction files weekly to catch those sneaky zombie beliefs is brilliant. Knowing that a rule that returns after deletion is read exactly as it did before adds such a layer of trust. The availability of these updates in public repos means I can verify everything myself. The interface is clean, and the distinction between clear and rotten rows is crystal clear. It feels like the tool is always working for me, ensuring that the standing instructions are always accurate. I love that I can add my own repo and see it listed by the same path open to everyone. This level of openness is exactly what the developer community needs right now. Keep up the fantastic work!
The Belief Rot Index offers a fascinating approach to tracking zombie beliefs in public repositories. The weekly census model provides clear visibility into retracted rules that have returned to force. The pricing structure seems reasonable given the depth of analysis, though the exact cost for continuous monitoring remains a question. It is good to see that corrections are shipped with receipts, ensuring transparency. For developers who value verifiable data, this tool provides significant value. I appreciate the self-listing option and the ability to run checks locally.

The Belief Rot Index is a weekly publication that scans public repositories for agent instruction files and identifies "zombie beliefs," defined as rules that were retracted and have since reappeared. Each week it produces a census listing tracked repositories along with a score, the number of zombie rules detected, and how long the oldest one has persisted, while keeping repositories unnamed unless their owners have consented. Users can verify a receipt or check their own repositories by running the accompanying sagrada-linter tool locally on their machine, and repository owners can add their projects to the index through a self-listing process. The project is run by Cruxia and presents its methodology and results openly on the site.
