What it does
Logic Locate is an agent skill from sickn33/agentic-awesome-skills. Locate the root cause of a CONFIRMED failure via backward-then-forward semi-formal tracing.
Its SKILL.md is about 980 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `logic-locate-guide.md`).
It sits in Development, covering Root cause analysis. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- Tasks that involve Root cause analysis
Example prompts
- “/logic-locate”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Read ../_shared/common.md only for language, Iron Law, Fault Confidence, scope routing, Remedy discipline, config fields, and loading…
- Read only the relevant step in logic-locate-guide.md as you reach it.
- Load ../_shared/logic-risks.md, ../_shared/semiformal-guide.md, ../_shared/semiformal-checklist.md, and ../_shared/report-template.md on…
What it can do on your machine
Read from SKILL.md and the folder at commit 680176d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Logic Locate loads about 977 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 485 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Logic-Lens — Fault Locate
When to Use
Use this skill when you need locate the root cause of a CONFIRMED failure via backward-then-forward semi-formal tracing. Trigger when the user provides a stack trace, failing assertion, error message, or specific wrong-value observation — "find the bug", "this test is failing", "track down this crash", "why is...
Setup
Use lazy loading per ../_shared/common.md §13:
- Read
../_shared/common.mdonly for language, Iron Law, Fault Confidence, scope routing, Remedy discipline, config fields, and loading budget. - Read only the relevant step in
logic-locate-guide.mdas you reach it. - Load
../_shared/logic-risks.md,../_shared/semiformal-guide.md,../_shared/semiformal-checklist.md, and../_shared/report-template.mdon demand when the current step needs them.
Process
Step 0. Language + scope routing. Detect language per common.md §1. Confirm a concrete failure exists (stack trace, failing assertion, specific wrong value). If only a suspicion, switch to logic-review.
Step 1. Understand the failure (guide Step 1) — observed behavior, expected behavior, reproduction path.
Step 2. Identify the entry point (guide Step 2) — failing test, outermost application frame, or request handler — whichever is closest to the failure. Stay inside the failure cone first: stack frames, failing test fixture, directly called local functions, and config/env values read on that path. Do not scan unrelated modules unless the trace crosses into them.
Step 3. Trace backward from the failure point (guide Step 3) — walk each value and state back to its origin, building premises at every hop.
Step 4. Trace forward to confirm (guide Step 4) — from the suspected root, verify the trace reaches the observed symptom.
Step 5. Interprocedural tracing if a callee is implicated (guide Step 5) — trace into the callee; check return values under observed conditions, unhandled exceptions, shared-state mutation. Apply the depth limit and Call-Chain Context Label format defined in semiformal-guide.md §Call-Chain Context Labels; at the limit, state the remaining callee path as a premise assumption and downgrade to Medium confidence (per common.md §7).
Show full SKILL.md (173 more words)Show less
Step 6. Identify the root divergence and classify (guide Step 6) — state the exact line/expression, the violated premise, the actual behavior, the propagation chain to the symptom; pick the L-code.
Step 7. Output the focused report (guide Step 7) — Fault Confidence (High/Medium/Low, per common.md §7); Primary Fault (single five-field finding); optionally Contributing Factors; a minimal Remedy per common.md §10. Format is mandatory even for simple one-function bugs: always emit the labeled Premises / Trace / Divergence / Trigger / Remedy fields and the Fault Confidence line. Never answer with a plain fix suggestion.
Mode line in report: Fault Locate (Chinese: 故障定位).
Output format: the Findings section has ONE Primary Fault, not a full Critical/Warning/Suggestion split. The Logic Score line is replaced by Fault Confidence: High / Medium / Low.
Limitations
- Use this skill only when the task clearly matches its upstream source and local project context.
- Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
- Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
