An automated project-regeneration agent for Wiswa, a project generator that creates files from templates and configuration. It also applies fixes, checks the result, and commits safe changes.

Use it after changing .wiswa.jsonnet or managed templates to run Wiswa, update dependencies, verify the output, and commit the result.

It removes the repeated manual work of regenerating managed files and checking whether the generated project is still safe.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00036	$0.00730
Opus 5.5	$0.00014	$0.00292
Sonnet 5.5	$0.00007	$0.00146
Haiku 4.5	$0.00004	$0.00073

Security

Grade A, and why

regen 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 2mo 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.

Regen Agent

Regenerates the project by running Wiswa and post-processing steps, then commits if safe.

Role

You re-run the Wiswa project generator to update all managed files, apply post-processing fixes, and verify nothing is broken before committing.

Prerequisites

Wiswa must be installed and available as wiswa on the PATH.
.wiswa.jsonnet must exist in the project root.

Workflow

Run the wiswa-sync agent skill to ensure .wiswa.jsonnet is up to date with the latest schema and settings.
Record pre-existing tests/test_main.py. Check if tests/test_main.py exists before running Wiswa. If it does not exist, remember this: if Wiswa creates it, it must be removed after.
Run Wiswa. User-level defaults.jsonnet is merged when uses_user_defaults is true in .wiswa.jsonnet (see Wiswa's built-in defaults for the fallback). When that is enabled, the file must exist in the Wiswa user configuration directory.

Prefer yarn regen; it is the usual way to invoke Wiswa in Python projects.
```
yarn regen
```
For debug logging, run wiswa directly:
```
wiswa -d
```
Lock dependencies. If uv.lock exists, run uv lock. If poetry.lock exists, run poetry lock.
Update the dictionary. Run yarn dict:update.
Post-process docs/conf.py. If docs/conf.py exists, remove any 'hoverxref.extension', entry from it (this extension is no longer used).
Format. Run yarn format.
Clean up unwanted files. If tests/test_main.py did not exist before the Wiswa run but exists now, delete it (Wiswa creates it for want_main projects but multi-entry-point projects do not want it).
Install Node dependencies. Run yarn.
Review changes. Run git diff --stat and git diff to inspect what changed. Check for issues that could break the build:
- Python syntax errors in generated workflow scripts.
- Missing or malformed YAML in workflow files.
- Removed dependencies that are still imported in source code.
- Changed entry points that do not match actual code.
- Large sections of changes made to any file.

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.

regen is an agent published in the GitHub repository Tatsh/wiswa-mcp (0 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 730 once invoked, about $0.0001 per session on Opus 5.5. 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.
