Removing both skill descriptions would make it harder for Claude Code and its users to distinguish commands that already share an invocation name. The ambiguity concerns command identity and scope, not the amount of prose in the description. Assign unique names or documented project/user scopes, then test which command resolves in the active environment. Hiding purpose information is not a conflict-resolution mechanism and can increase accidental invocation of the wrong behavior.

Selecting the most recently installed skill is a race based on installation history, not evidence that it implements the user's intended workflow. Two teams may use the same command name for incompatible effects; silently changing its meaning can make a safe review invoke a mutating process. Give the skills distinct names or explicit namespaces and make their descriptions and tool permissions unambiguous. Resolve the collision as configuration, rather than relying on whichever package happened to be installed last.

Running both same-named skills on every invocation can produce incompatible side effects, such as one skill generating a report while the other mutates or publishes resources. The user may have intended only one workflow and may not have authorized the second. Resolve the command name collision before dispatch, document which implementation is selected and scope each skill's capabilities. Executing both indiscriminately turns ambiguous discovery into duplicate work or unauthorized operations rather than clarifying the contract.

The user-invocable field governs whether the user sees and can invoke a skill from the command interface. Setting it to false hides the manual invocation route while still allowing Claude to invoke the skill itself, which reverses the required control. The deployment operation should be user-initiated, so this field is not the appropriate safeguard. It is useful for skills meant only as automatically applied background knowledge, not an explicitly invoked production-release command.

The context: fork frontmatter option controls the execution context, such as running a skill in a separate subagent rather than inline. Isolation can make a large procedure easier to manage, but it does not prevent Claude from choosing to invoke the skill when a request seems relevant. A production release requires invocation control as well as any desired isolation. Context placement and permission to start a side-effecting workflow are different concerns and should not be confused.

The allowed-tools field grants specified tool use within the invocation, subject to the surrounding permission model. Declaring Bash does not decide who can launch the skill and may authorize shell activity during a production procedure. It is neither a manual-trigger restriction nor a general guarantee that a deploy will be safe. Tool permissions should be scoped narrowly, but restricting automatic skill selection must be expressed by a separate invocation-control setting.

A warning displayed only after critical deletion cannot prevent the side effect. By that point the file or external resource may already be gone, and the owner has no meaningful opportunity to decline. The execution host must gate the destructive call on real prior consent and the exact target. Documentation may explain why confirmation is required, but placement after mutation makes it ineffective as a safety boundary.

Deleting first and requesting approval afterward reverses the required decision order. Permission is needed before the consequence, not as a retrospective statement that the user would have agreed. Even if an undo operation exists, the resource may have been copied, external systems notified or recovery made impossible. The workflow should identify the target, present material effects and wait for a real authorization result before allowing the deletion tool to run.

A default yes value in a command schema may cause a call to proceed when the user supplied no confirmation at all. It is not equivalent to explicit informed approval for a critical deletion. The host should require an affirmative authorized response tied to the actual target and effect, and reject missing or stale confirmation. Schemas validate data shape but cannot substitute for an authenticated consent workflow.

A reusable skill may encode useful defaults, but an unfamiliar repository can impose different language versions, safety rules or test runners. Running default edits before inspecting local guidance risks violating project-specific constraints. The correct preparation is to read applicable repository instructions and validate tool permissions, then adapt the skill’s workflow before touching files. Post-edit reconciliation cannot reliably undo every side effect.

A destructive cleanup is not a prerequisite for understanding an unfamiliar codebase. Deleting generated files, caches, or configuration before reading local instructions can erase evidence and trigger unintended changes. The safe first action is non-mutating discovery: identify the repository's active guidance, installed dependencies, existing test commands and the exact requested change. Only a cleanup explicitly justified by those findings and authorized in scope should be considered afterward.

Overwriting the root configuration before inspecting an unfamiliar repository risks removing project-specific build commands, access controls and conventions that the code-generation skill must respect. A generic default can be syntactically valid while breaking deployment or violating ownership rules. First read the applicable instructions and dependency manifests, identify the requested target and approved file scope, then prepare the smallest justified edit. A reusable skill should adapt to the repository rather than demand that the repository adopt its assumptions.

An invocation log records that the API-documentation skill was called, but it does not explain or authorize the unexpected deployment step. The defect is the skill exceeding its declared output and side-effect contract, not the presence of an audit record. Maintain logs so reviewers can see the attempted action, while restricting the skill to reading interfaces and generating documentation. Production deployment must require a separate authorized workflow with its own checks and confirmed execution receipt.

The number of code examples in generated API documentation does not explain why a documentation skill tried to deploy a service. Examples might affect readability or scope but do not grant permission for external mutation. This is a tool-authority and skill-boundary defect: the user authorized documentation generation, not a release operation. Remove or gate deployment capabilities, and require a separate explicit approval for any later deployment. Do not confuse editorial length with side-effect authorization.

Whether documentation is delivered as Markdown or HTML does not determine whether the skill exceeded its permission scope. The requested output is API documentation; deploying the service is an additional state-changing operation with separate release consequences. A file format choice cannot authorize a network deployment. The skill must stop after generating and validating documentation unless a specifically approved publishing workflow is invoked with its own target and acceptance gates.

Skill documentation cannot provide executable capabilities that are absent from a particular Claude Code client. Claiming universal compatibility would make the older installation fail unpredictably and could encourage unsupported workarounds. Test the skill against the advertised tool catalogs and record its minimum supported version. If the new file-reading API is essential, return a clear unsupported status rather than falsely claiming that a review ran successfully.

Renaming a skill changes how it is invoked but does not add the required file-reading tool to the host registry. This workaround can also break users’ existing automation and obscure which skill version produced a report. The maintainer should test feature detection and provide a supported fallback or a documented minimum client capability. Stable names and explicit compatibility requirements are preferable to disguising a missing implementation dependency.

Executing a guessed shell command based on a missing tool name crosses the host’s supported capability boundary and can cause unreviewed side effects. Shell availability and arguments are separate execution privileges; they cannot be inferred from the name of an absent reader. The skill must either use a documented supported fallback with appropriate permissions or reject that installation as incompatible. Otherwise users may receive false review evidence or unsafe commands rather than a controlled capability error.

Tone is not a reliable way to determine whether a path-specific TypeScript security rule applies. The assistant may sound confident while editing a file outside the intended payments subtree, or overlook a nested path that should be covered. Configure the actual glob under a supported project rules location and verify matches with representative filenames. Scope enforcement should depend on path and rule metadata, not conversational style or the model's intuition.

A personal global instruction file applies to a broader audience and may not travel with the repository or CI environment. That is the wrong scope for guidance intended only for TypeScript under src/payments. It could also overconstrain unrelated JavaScript or Python tasks outside this project. Store the project rule in a supported path-aware location, anchor the glob to the target directory and verify matching behavior on both intended and nonmatching files. Personal settings should not substitute for reviewed shared instructions.

Renaming Python files to have .ts extensions merely to satisfy a TypeScript rule would misrepresent source language and could break build tooling, syntax highlighting or import behavior. The requirement is to apply additional instructions to files that genuinely match a known target subtree and language. Configure the supported path glob correctly instead of altering unrelated files. A name change does not make Python code safe under TypeScript-specific validation, nor does it solve instruction-loading logic.

Glob matching semantics depend on the tool and pattern, and many single-star patterns match only one directory level. Here the failing path is nested under src/payments, so assuming implicit recursive matching can leave precisely the sensitive file unprotected. Inspect the actual path matcher, anchor point and support for a recursive expression such as **/*.py before changing the security rule. Validate the resulting matched and unmatched paths in tests rather than treating the extension alone as proof of coverage.

The presence or absence of the word Python inside a file is unrelated to whether a path-scoped rule matches its directory and extension. The example file is nested under src/payments, while the current glob may only cover a top-level location. Inspect the supported glob semantics, add an explicitly scoped recursive pattern if appropriate and test both covered and excluded paths. File contents are not a reliable substitute for correctly anchored filesystem matching.

Banning Bash may prevent useful read-only commands but would not necessarily cover Edit, Write or a separate filesystem-capable plugin. The identified defect is a path pattern that misses nested Python files, not a universal need to block every shell command. Repair the recursive matching scope and test sensitive paths through every relevant write-capable interface. A broad denial can increase false positives while still leaving alternate mutation paths available, so it does not establish the intended coverage.

Applying the strictest integration-test rule to every repository file may block unrelated production edits and hides why the rule was intended for a narrow package. A condition that is appropriate for integration fixtures may not apply to frontend or deployment sources. Fix the path matching at its definition, then confirm included and excluded examples in the instruction loader. Broad global enforcement is not a substitute for accurate path-scoped guidance.

A suffix-only match includes tests outside the intended integration package, which is exactly the defect described. Manual review after applying the rule cannot prevent the instruction from affecting unintended files during tool execution. Scope must be enforced by a path-aware pattern before the rule is loaded. Anchoring to the correct package directory prevents unrelated production test files from inheriting the integration-only behavior.

A one-file exception may suppress the current symptom but leaves the overbroad pattern active for every other matching production test. New test files could silently inherit the same misplaced instruction. The root cause is the rule’s path selector, not one filename. Tighten the glob to the intended package and verify representative matched and unmatched paths before accepting the configuration.

A maintainer's preference for YAML has no bearing on whether the frontmatter parses under the supported rule format. If the paths field contains an invalid list, Claude Code may ignore the scope or apply the guidance incorrectly. Inspect the actual syntax, correct the expected array structure and test which files match. Personal enthusiasm for one serialization format cannot make an invalid configuration machine-readable.

Markdown rendering can succeed while a malformed frontmatter structure is ignored or interpreted incorrectly by the instruction loader. The paths field governs which files receive the rule, so syntactic validity and actual glob matching must be checked separately from the displayed body text. A maintainer should parse the YAML with the supported schema and test the intended file patterns. A pretty preview provides no evidence that scoped instructions will activate.

A distant file sharing the same basename does not show whether this rule's YAML metadata parses or whether its path patterns match the intended source. The problem is the malformed paths field, which can prevent the instruction from being applied. Inspect the actual rule file, validate the frontmatter against supported syntax and test loading on representative paths. Filename coincidence elsewhere in the repository offers no evidence that this configuration is effective.

A stronger instruction can reduce accidental requests but is not an enforcement boundary. An agent can still attempt to modify a tracked generated artifact through Edit, Write, or shell commands despite the reminder. The observed failure is a write that should have been prevented, so the project needs host-side deny rules, filesystem restrictions, or CI checks against protected output paths. Prompt guidance can accompany those controls but cannot replace them.

Git ignore rules govern whether untracked files are offered for version control; they do not make existing tracked files read-only, and they do not prevent a process from changing bytes on disk. If the generated dist/app.js file is already tracked or writable, an agent can still modify it. Enforce the protected output boundary through file permissions, tool-policy restrictions, or CI verification, and regenerate artifacts only through an authorized build pipeline.

Post-build deletion may hide a modified generated artifact from the package, but it does not prevent the unauthorized edit to the working tree or the possibility that other tasks already consumed the changed file. It also risks deleting legitimate build output. The boundary should reject or detect writes to the protected generated directory before acceptance, with a clean rebuild and version-aware review where necessary. Removing a file after the fact is not equivalent to enforcing the no-edit path policy.
