At a glance

Scores a coding task on Spread, Novelty, and Centrality (SNC 0-6) and maps the tier to autonomy, verification depth, review mode, reviewers, model tier.

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Choosing fast vs deep review

What it does

Common Task Complexity Routing is an agent skill from HoangNguyen0403/agent-skills-standard. Scores a coding task on Spread, Novelty, and Centrality (SNC 0-6) and maps the tier to autonomy, verification depth, review mode, reviewers, model tier. Use when sizing a fix or feature before planning, choosing fast vs deep review, or deciding whether HARD STOP approval is required.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `evals/evals.json`, `references/routing-table.md` and `references/snc-rubric.md`).

The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Feature before planning
  • Choosing fast vs deep review
  • Deciding whether HARD STOP approval is required

Example prompts

  • “Use the common-task-complexity-routing skill to score a coding task on Spread, Novelty, and Centrality (SNC 0-6) and maps the tier to autonomy…”
  • “/common-task-complexity-routing”

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. 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

Common Task Complexity Routing loads about 1.1k tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 466 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~79
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.5k

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.

Task Complexity Routing (SNC)

Priority: P1 (HIGH)

Same ticket label, different engineering difficulty. Score the task, not the label, then route by tier.

Score

Dimension012
Spread (how far the change reaches)one file, one moduleseveral files, one modulecross-module or cross-service
Novelty (new vs existing behavior)small edit or removal of existing behaviormodify existing logicnew behavior or rewrite
Centrality (how core the touched code is)peripheral codeshared but non-corecore domain, hot path, auth, money, trust boundary

Sum the three, never average. Output line: SNC: S=[0-2] N=[0-2] C=[0-2] total=[n] tier=[low|medium|high].

Tiers

  • tier=low: total 0-2
  • tier=medium: total 3-4
  • tier=high: total 5-6

Routing

TierAutonomyVerificationReviewApprovalmodel_tier
tier=lowautonomousbasic: focused tests + lintfast code-reviewnone requiredfast
tier=mediumguidedTDD + self-reviewdeep code-reviewplan reviewed, no HARD STOPstandard
tier=highplan-firstTDD + independent reviewers (specialist-architecture-guard, specialist-security-reviewer when relevant)deep code-reviewHARD STOP before code, human approval before mergestrong

Sensitive-Change Risk Floor

Sensitive changes touching authentication, authorization, payments/financial data, data integrity, secrets, or system trust boundaries have an explicit risk floor independent of arithmetic SNC totals:

  • Floor: Minimum tier=medium (guided execution, deep review, human plan acknowledgment) even if arithmetic total is ≤2 (e.g. S=0, N=0, C=2).
  • High Sensitivity: If spread or novelty is non-zero (S≥1 or N≥1 with C=2), enforce tier=high (plan-first HARD STOP, independent security review, human merge approval).
  • Irreversible Actions: Actions involving data destruction, schema drops, credential rotation, privilege escalation, or production cutover strictly require explicit human authorization regardless of tier.

Rules

  • Score before planning; emit snc_tier and model_tier in every Handoff Payload.
  • Label the score as inference when derived from ticket text alone; re-score after specialist-codebase-scout reports impact radius.
  • Round up on doubt. Any auth, money, trust-boundary, or hot-path touch is C=2 and subject to the sensitive-change risk floor.
  • Downward complexity reassessment is permitted ONLY with documented new evidence (e.g., scouted blast radius proves isolated scope with verified non-interference), NEVER to bypass unresolved risk, required approvals, or the sensitive-change risk floor.
  • Re-score when scope grows mid-task; the tier must rise immediately when expansion is detected.
  • Never downgrade a tier to skip a gate. Ticket type (bug vs feature) never sets the tier.

Red Flags

Stop and re-score when hearing or thinking: "it's just a bug fix", "one-line change", "skip the plan, it's small", "we'll review it later", "mark it low so we can merge tonight". Each is a rationalization, not a score.

Anti-Patterns

  • No tier by ticket type: "bug" and "feature" say nothing about S, N, or C.
  • No averaging: three 1s and one 2/0/1 both route differently only when summed.
  • No silent tier: a plan or handoff without snc_tier is incomplete.
  • No high tier without named reviewers: tier=high must list which specialists review before merge.
