How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
4 rules. About 0 are common, 4 are distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈4
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 14
Use this parent skill as the active SDLC documentation entrypoint.
- Distinctive: line 48
Every document must be tied to a decision, acceptance criterion, release gate, or operating obligation.
- Distinctive: line 50
Avoid generic SDLC text that cannot guide an implementation or audit decision.
- Distinctive: line 88
Read and search are required.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

SDLC Documentation
Acknowledgement: Shared by Peter Bamuhigire, techguypeter.com, +256 784 464178.
Use this parent skill as the active SDLC documentation entrypoint. Keep the phase-specific details in references and load only the phase being authored or reviewed.
<!-- dual-compat-start -->Use When
- Creating or reviewing SDLC document sets, delivery evidence, traceability, phase gates, and lifecycle handoffs.
- Consolidating planning, design, testing, deployment, user rollout, post-deployment, and maintenance documents.
- Aligning project documentation with implementation, validation, release, and support obligations.
Do Not Use When
- The task is unrelated to this parent skill or is better handled by a narrower active parent named in the workflow.
- The request only needs a trivial answer and no reference module needs to be loaded.
Required Inputs
| Artefact | Required? | Purpose |
| System, repository, environment, and constraints | yes | Ground the document in actual delivery context |
| Requested lifecycle phase and audience | yes | Select only the needed reference and output |
Workflow
- Load
world-class-engineeringfor baseline delivery quality. - Load the needed phase reference:
references/sdlc-planning.mdfor project planning and initiation.references/sdlc-design.mdfor solution and technical design documents.references/sdlc-testing.mdfor test planning, evidence, and acceptance gates.references/sdlc-user-deploy.mdfor user rollout and adoption documents.references/sdlc-post-deployment.mdfor go-live review and stabilisation evidence.references/sdlc-maintenance.mdfor support, maintenance, and continuous improvement.
- Pair with
project-requirements,advanced-testing-strategy,deployment-release-engineering, orimplementation-status-auditorwhen the task needs those outputs.
Quality Standards
- Every document must be tied to a decision, acceptance criterion, release gate, or operating obligation.
- Preserve traceability from requirement to design, implementation, test evidence, release, and support.
- Avoid generic SDLC text that cannot guide an implementation or audit decision.
Anti-Patterns
- Treating absorbed reference files as active skills or separate routing entrypoints.
- Loading every migrated child reference instead of the one that matches the task.
- Producing generic advice without constraints, evidence, or next verification steps.
Outputs
- SDLC document, review findings, traceability notes, phase gate checklist, or handoff package.
Evidence Produced
| Category | Artifact | Format | Example |
| Correctness | Traceability results | Matrix | Requirement-to-test mapping |
| Security | Security review | Findings register | Unresolved authorization risk |
| Data safety | Data-control evidence | Checklist | Recovery verification |
| Performance | Performance verification | Test record | SLO result |
| Operability | Operational handoff | Runbook and checklist | Monitoring ownership |
| UX quality | User validation | Acceptance record | Accessibility result |
| Release evidence | Release decision | Approval record | Signed gate outcome |
References
- Load only the references/
<old-skill>.md files named in the workflow when their depth is required.
<!-- dual-compat-end -->Decision Rules
| Condition | Action |
| One lifecycle phase is requested | Load only its absorbed reference |
| Evidence conflicts with an older document | Flag and reconcile before update |
| Required operational fact is unknown | Mark it open; do not invent it |
Capability Contract
Read and search are required. Editing and validation execution require authorisation.
Degraded Mode
Fallback: without repository evidence, return a document skeleton and open-question register.
Domain Anti-Patterns
- Copying every phase template into one document.
- Presenting planned behaviour as implemented.
- Omitting owner or acceptance evidence.
- Leaving stale cross-document contradictions.
- Inventing deployment or maintenance facts.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
