|
|
|
* Executive Summary
|
|
Verified the autonomous repair capability of the `Self-Fix Agent`. The system successfully detected a deterministic type error in a secondary skill, initiated a repair request, and programmatically patched the source code via the `:repair-file` tool.
|
|
|
|
* 1. Issue: Self-Fix Mechanism Verification
|
|
** Symptoms
|
|
Manual verification was required to prove that `org-skill-self-fix` could transition from "Thinking" about a bug to "Acting" on the file system.
|
|
** Root Cause
|
|
N/A (Deterministic test injection).
|
|
** Resolution
|
|
Created `self-fix-tests.lisp` which:
|
|
1. Generates `org-skill-broken-math.org` with a `(+ 1 "two")` bug.
|
|
2. Triggers the bug to produce a `PIPELINE CRASH`.
|
|
3. Injects a `:repair-request` stimulus.
|
|
4. Executes `self-fix-apply` to replace the bug with `(+ 1 2)`.
|
|
5. Verifies the file content and successful hot-reload.
|
|
|
|
* 2. Side-Issue: ASDF Configuration Fragility
|
|
** Symptoms
|
|
Repeated `LOAD-SYSTEM-DEFINITION-ERROR` and "unmatched close parenthesis" errors during test integration.
|
|
** Root Cause
|
|
Complexity in the `:components` nesting of `org-agent.asd` led to repeated syntax errors when using automated editing tools. The deep nesting made manual paren counting prone to "off-by-one" errors.
|
|
** Resolution
|
|
Refactored `org-agent.asd` to use a **Flat Component Structure**.
|
|
- *Before:* `:components ((:module "src" :components (...)))`
|
|
- *After:* `:components ((:file "src/package") ...)`
|
|
This eliminates unnecessary nesting levels and drastically reduces the surface area for syntax errors.
|
|
|
|
* 3. PSF Mandate Alignment
|
|
** Invariant Check
|
|
- *Lisp Machine Sovereignty:* Verification utilized hot-reloading (`load-skill-from-org`) without restarting the SBCL image.
|
|
- *Literate Programming:* Updated `org-skill-self-fix.org` to match the finalized `self-fix.lisp` logic.
|
|
- *Institutional Memory:* This RCA documents the decision to flatten the `.asd` structure to prevent future "Parenthesis Hell" incidents.
|
|
|
|
* 4. Permanent Learnings
|
|
- **Flatten Configuration:** Keep `defsystem` definitions as flat as possible. The overhead of `:module` blocks often outweighs their organizational benefit in a probabilistic-deterministic environment where agents frequently edit these files.
|
|
- **Mocking Probabilistic Engine:** For verifying *loop mechanics*, mocking LLM responses is essential to ensure test determinism, while integration tests can use live LLM calls.
